Description

[0001] CLAMPING SYSTEM

[0002] TECHNOLOGICAL FIELD

[0003] The presently disclosed subject matter relates to systems for releasably clamping or connecting together two components.

[0004] BACKGROUND

[0005] A variety of systems are known in which it is necessary to releasably join or clamp or otherwise connect two elements or structures together.

[0006] In one such class of systems relating to aerospace applications, it is often necessary to releasably connect or clamp together a lower stage and a higher stage of a rocket launch vehicle, and to release such connection / clamping once the lower stage has terminated its part of the mission. In many such cases there it is often also necessary to releasably connect or clamp together a payload to a stage of the launch vehicle, and to release the payload at some point in the launch process, and / or to detach a fairing that covers the payload for the initial stages of the launch.

[0007] For example, LM-3A Series Launch Vehicle User’s Manual Chapter 4 relates to payload fairings, which is designed to limit the aerodynamic thermal load transmitted to the satellite and attenuate the acoustic loads from the main engines during launch.

[0008] In many such applications, clampbands are often used for temporarily joining the various components together, and the clampbands are disengaged from the components when separation of the components is required. Common examples of such clampbands are based on Marman clamps.

[0009] Other solutions include a system of pyrotechnic bolts that hold the components together, and that are explosively sheared when separation of the components is required. By way of non-limiting example, WO 2023 / 111463 relates to an assembly that is separable by means of pyrotechnic cutting, the assembly comprising a structure to be cut, a holding element and a detonating cord, the assembly being characterized in that the detonating cord has an oblong cross section, the shortest axis of symmetry of which extends between a first elongate surface and a second elongate surface of the detonating cord, the detonating cord being arranged in a cavity formed between the structure to be cut and the holding element such that the first elongate surface of the detonating cord is held in contact with the structure to be cut and such that the second elongate surface of the detonating cord is held in contact with the holding element.

[0010] Also by way of non-limiting example, KR 20170136890 relates to utilizing the force of release of gas which occurs when a flexible detonating fuse detonates in terms of a cutting method applied when missiles and space launch vehicles are separated. While the conventional cutting method is provided to cut a weak portion of a lid using the inflation force by an inflatable tube, the present invention is configured to effectively introduce emitted gas into a fragile portion and cut the emitted gas by the pressure, thereby reducing impact transmitted to a launch vehicle which is less than that of the conventional method, thereby minimizing damage to an internal device. According to the present invention, the cutting device using a flexible detonating fuse includes: a cylindrical tube having a central portion penetrated; and a U-shaped columnar gas guide portion having predetermined thickness, wherein the tube is positioned in contact with the gas guide portion.

[0011] Also by way of non-limiting example, US 8,967,030 discloses a device comprising a bolt including a locking member which is mounted such that it can slide with respect to a first component and can adopt a locked position in which the locking member retains the second component and an unlocked position in which the locking member releases the second component, the transition from the locked position to the unlocked position taking place under the action of pyrotechnic means. In addition, a branch that is at least partially deformable under the action of the pyrotechnic means is arranged with respect to the holt in such a way that the transition from the locked position to the unlocked position takes place by means of the deformation of said branch. Also by way of non-limiting example, US 7,127,994 discloses methods and apparatus for a low shock separation joint. A first member couples to a first structure and includes surfaces to prevent separation under compressive and tensile force placed on the separation joint. A second member couples to a second structure and includes surfaces corresponding to the surfaces of the first member. The first member is elastically flexed to allow the surfaces of the first and second members to be aligned to one another. The first member is released from flexing which couples the first and second members together. An explosive device is placed within the separation joint. Detonating the explosive device moves the surfaces of the first and second members out of contact with one another decoupling the first and second members. A passive force is applied to accelerate the first and second members away from one another. After detonation the first and second members are intact.

[0012] Also by way of non-limiting example, US 2003 / 196544 discloses a temporary connection and pyrotechnic separation device that normally connects two elements. This device comprises a connecting part, of which a bottom portion is fixed to one of the elements. Active portions of the connecting part cover a space in which there is pyrotechnic expansion tube. The active portions are deformable and comprise hookshaped ends that fit into a notch formed in the second element, so that normally there is a pressure connection between the two elements. The effect of firing is to deform the active parts and consequently break this pressure connection.

[0013] Also by way of non-limiting example, US 6,820,559 discloses a temporary connection of two elements that is ensured by U-shaped connecting components held in place by a moving part. A pyrotechnic composition is housed between two shoulders situated respectively on the first of the elements and on the moving part. Igniting the pyrotechnic composition causes the moving part to slide over the first element. The connecting components are released and the connection between the elements is said rto be eliminated without breaking any parts.

[0014] Also by way of non-limiting example, "Refinement of a Low-Shock Separation System" (Chuck Lazansky ~ Proceedings of the 41st Aerospace Mechanisms Symposium, Jet Propulsion Laboratory, May 16-18, 2012), discusses the design of Marman Clamp-band Separation Systems, and several lessons learned by SNC over 12 years and multiple programs. An overview of the purpose, components, and function of a clamp-band system are presented.

[0015] Also by way of non-limiting example, "Separation Joint Technology" (Jamesd E. Fritz ~ 39thAIAA / ASME / SAE / ASEE Joint Propulsion Conference, Huntsville, Alabama, July 20-23, 2003) provides a historical overview of linear explosive separation technologies.

For example, the holding plate is configured for providing load-bearing connection between the first wedge element and the first shoulder, and between the second wedge element and the second shoulder, in the engaged configuration. For example, said load bearing is in said first direction. Additionally or alternatively, for example, the first holding element abutment surface is complementarily shaped with respect to the first flange abutment surface, such that mechanical contact between the first holding element abutment surface and the first flange abutment surface enables loads to be transmitted via the mutually abutting surfaces.

Additionally or alternatively, for example, said second inclination angle is any one of 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 80°, 90°.

[0023] Additionally or alternatively, for example, the second holding element abutment surface is inclined at the second inclination angle with respect to the reference longitudinal axis.

[0024] Additionally or alternatively, for example, the second holding element abutment surface is configured for being in load-bearing and abutting contact with the second flange abutment surface at a second contact plane, wherein the second contact plane is inclined at the second inclination angle with respect to the reference longitudinal axis.

[0025] Additionally or alternatively, for example, said first inclination angle and said second inclination angle are equal to one another, or, said first inclination angle and said second inclination angle are unequal with respect to one another.

[0026] Additionally or alternatively, for example, said reference spacing is parallel to the reference longitudinal axis, and wherein said reference spacing is sized such as to ensure load-bearing abutting contact between the first wedge element and the first shoulder, and between the second wedge element and the second shoulder, in the engaged configuration. Additionally or alternatively, for example, said reference spacing is sized such as to ensure load-bearing abutting contact between the first holding element abutment surface and the first flange abutment surface, and between the second holding element abutment surface and the second flange abutment surface.

[0027] Additionally or alternatively, for example, said reference spacing is sized such as to ensure that, when the clamping system is in the engaged configuration and is affixed to the first component and to the second component, the first component and the second component are in, and are maintained in, a predetermined relative spatial dispositions with respect to one another.

[0028] Additionally or alternatively, for example, the orthogonal load bearing arrangement is configured for providing shear resistance for the holding plate in the second direction, generally orthogonal to the reference longitudinal axis, and thereby prevent relative movement between the holding plate and each one of the first flange arrangement and the second flange arrangement in the engaged configuration.

[0029] Additionally or alternatively, for example, the orthogonal load bearing arrangement is configured for providing a resisting force between the at least one holding plate and the first flange arrangement and the second flange arrangement, in the second direction orthogonal to the reference longitudinal axis, in the engaged configuration, and to discontinue said resisting force in the disengaged configuration. For example, the orthogonal load bearing arrangement comprises a first plurality of shear pins that are engaged directly between the first component and the at least one holding plate, and a second plurality of shear pins that are engaged directly between the second component and the at least one holding plate.

For example, said predetermined shearing force is selectively provided responsive to activation of the actuator device. Additionally or alternatively, for example, the actuator device selectively operates to selectively apply a force to the at least one holding plate in the second direction, sufficient to shear the plurality of shear pins.

For example, said short time period is in the order of microseconds, or in the range of example 1 to 10 milliseconds to 1 to 10 microseconds, or in the range between 1 microsecond to 100 microseconds.

[0036] Additionally or alternatively, for example, the actuator device comprises a pyrotechnic system for selectively morphing the shape of the tube element from the first tube configuration to the second tube configuration responsive to a suitable activation command.

[0041] Alternatively, for example, said first component is one stage of a rocket launch vehicle, and wherein said second component is an adjacent stage of the rocket launch vehicle.

[0070] DETAILED DESCRIPTION

[0071] Referring to Fig. 1, a clamping system, according to a first example of the presently disclosed subject matter, generally designated 100, comprises a first flange arrangement 200A, a second flange arrangement 200B, a holding arrangement 300, and an actuator device 400.

[0072] The clamping system 100 (also interchangeably referred to herein as a connection system) longitudinally extends along a system axis SA, which can be rectilinear or curved, or can have bends, for example, depending on the specific application of the clamping system 100. The clamping system 100 is configured for releasably connecting a first component 10 and a second component 20 in a first direction A parallel to a reference longitudinal axis LA. The clamping system 100, the first component 10 and the second component 20 together form an assembly 50, when connected such that the first component 10 and the second component 20 are releasably clamped to one another via the clamping system 100.

[0073] As will become clear herein, the clamping system 100 has an engaged configuration EC and a disengaged configuration DEC. In the engaged configuration EC, the first flange arrangement 200A, the second flange arrangement 200B, and the holding arrangement 300 are mutually engaged, and the actuator device 400 has not yet been activated. In the engaged configuration EC the first component 10 and the second component 20 are mechanically engaged to one another via one or more clamping systems 100, and the resulting assembly 50 behaves as a single body. In the disengaged configuration DEC, the first flange arrangement 200A, the second flange arrangement 200B, and the holding arrangement 300 are mutually disengaged, as a result of activating the actuator device 400, thereby disengaging the first component 10 and the second component 20 from one another..

[0074] In at least one example, the first component can be one stage of a rocket launch vehicle, and the second component can be an adjacent stage of the rocket launch vehicle, for example: the first and second stages, respectively of a rocket launch vehicle; or, the second and third stages, respectively of a rocket launch vehicle; or, the third and fourth stages, respectively of a rocket launch vehicle.

[0075] For example, referring to Figs. 8(a) and 8(b), the second component 20 can be the penultimate stage STP of a rocket launch vehicle, and the first component 10 can be the last stage STU of the rocket launch, or, the first component 10 can be a fairing that is provided to protect the payload for the initial stages of the launch.

[0076] In at least another example, the first component can be a payload carried by a rocket launch vehicle, and the second component can be an adjacent stage of the rocket launch vehicle; for example, the payload can be one or more satellites.

[0077] In at least another example, and for example referring to Figs. 9(a) and 9(b), the first component 10 and the second component 20 are each fairing halves, and can together provide a fairing that is provided to protect a payload for the initial stages of the launch. In at least some such examples, for example, and referring again to Figs. 8(a) and 8(b), the reference longitudinal axis LA can be coaxial or parallel to a central longitudinal axis CAX of the rocket launch vehicle, or the common central longitudinal axis CAX of the adjacent stages, or of one of the stages thereof. In yet other examples, and referring again to Figs. 9(a) and 9(b), the reference longitudinal axis LA can be orthogonal to a central longitudinal axis CAX of the rocket launch vehicle or of the fairing itself.

[0078] As will become clearer herein, while in some applications of the presently disclosed subject matter only a single clamping system 100 is required to clamp together the first component 10 and the second component 20, in other such applications two or more than two clamping systems 100 can instead be required to clamp together the respective first component 10 and the respective second component 20; in such latter cases each clamping system 100 of the plurality of clamping systems 100 can include its own respective actuator device 400, or two or more such clamping systems 100 can share the same actuator device 400.

[0079] In some applications of the presently disclosed subject matter, and as illustrated in Figs. 1, 8(a), 8(b), 9(a), 9(b) for example, the clamping system 100 can be provided on external portions of the respective first component 10 and the respective second component 20. Conversely, in other alternative applications of the presently disclosed subject matter, the clamping system 100 can be provided on internal portions of the respective first component and of the respective second component.

[0080] For example, in the example illustrated in Figs. 8(a), 8(b), 10, the clamping system 100 is configured for releasably connecting and locking together a first component 10 and a second component 20, in which by way of non-limiting example the first component 10 and the second component are generally cylindrical, and coaxially aligned about the common longitudinal reference axis LA. While in the illustrated example of Fig. 10 a number of serially aligned clamping systems 100 together partially or fully circumscribe the circumference of the first component 10 and the second component 20 when clamped together, in at least some alternative variations of this example a single clamping system 100 is configured for circumscribing the entire circumference of the first component 10 and the second component 20 when clamped together. In at least some examples, the locking system 100 comprises a single actuator device 400 configured for concurrently activating all said locking devices 200 of the plurality of locking devices 200. In alternative variations of this example, the locking system 100 comprises a number of actuator devices 400 (for example 2, 3, 4, or more than 4 actuator devices 400), and each actuator device 400 is configured for concurrently activating all said locking devices 200 of a set of 1, 2, 3, 4 or more than 4 locking devices 200.

[0081] For example, in the example illustrated in Fig. 10, the respective clamping system 100 is configured for releasably connecting and locking together a first component 10 and a second component 20, in which by way of non-limiting example the first component 10 and the second component are generally cylindrical, and coaxially aligned about the common longitudinal reference axis LA.

[0082] In alternative variations of this example, at least one of the first component 10 and the second component 20 is cylindrical, and / or, at least one of said first component 10 and the second component 20 is frustro conical. In yet other alternative variations of this example, both the first component 10 and the second component 20 are cylindrical, or, both said first component 10 and the second component 20 are frustro conical.

[0083] In yet other alternative variations of this example, the first component 10 and the second component 20 are each fairing parts in the form of fairing halves, for example as illustrated in Fig. 9(a) and Fig. 9(b), and are releasably engaged together with the system 100 to provide the complete fairing. In yet other alternative variations of this example, the complete fairing can be made from a plurality of fairing parts or segments that are adjacently connected together, in a transverse and / or longitudinal direction, for example. In such a case, the first component 10 and the second component 20 are each in the form of such fairing parts or segments that are releasably engaged together with the system 100 to provide a unit of two engaged fairing segments. Such a unit can in turn be releasably engaged to other such fairing parts or segments, each time using a system 100.

[0084] Referring again to Fig. 1, and also to Fig. 2, and Fig. 2(a), the clamping system 100 is configured for releasably clamping together the first component 10 and the second component 20. In particular, the first component 10 comprises a first interface zone 12, and the second component 20 comprises a second interface zone 22, and the clamping system 100 is configured for being affixed to each one of the first interface zone 12 and the interface zone 22.

[0085] For the purpose of example, and in at least the example, of Figs. 1, 2, 2(a), the first component 10 and the second component 20 are illustrated as being generally planar, and the clamping system 100 correspondingly extends along the respective system axis SA, wherein the system axis SA is nominally rectilinear in this example. However, and as will become clearer herein, the precise form and curvature of each respective clamping system can vary according to the geometry of the respective first component 10 and the respective second component 20, in particular according to the geometry of the respective first interface zone 12, and the respective first interface zone 22 of the respective first component 10 and the respective second component 20, respectively. Thus, and as will become clearer herein, in examples in which the geometry of the respective first interface zone 12 and of the respective first interface zone 22 is generally curvuate, for example, the respective system axis SA is also correspondingly curvuate.

[0086] In any case, and referring again to Fig. 2(a), in at least this example, the first interface zone 12 is in the form of a strip or flange at one end of the first component 10, and comprises a first free edge 14, and a first upper surface 15 and a first lower surface 16 each extending from the first edge 14 and separated from one another by the first thickness Tl. Similarly, and in at least this example, the second interface zone 22 is in the form of a strip or flange at one end of the second component 20, and comprises a second free edge 24, and a second upper surface 25 and a second lower surface 26 each extending from the second edge 24 and separated from one another by the second thickness T2.

[0087] Referring also to Fig. 3, the first flange arrangement 200A, is configured for being affixed to the first component 10, in particular for being affixed to the first interface zone 12 of the first component 10. In at least this example, the first flange arrangement 200A comprises a pair of first flanges 210A and 220A separated from one another by a first spacing SP1, defining a first cavity CV1. While in at least this example, first flanges 210A and 220A parallel to one another, in at least some alternative variations of this example, the first flanges 210A and 220A can be converging or diverging with respect to one another.

[0088] In at least this example, the first spacing SP1 corresponds to the first thickness Tl, and thus the first interface zone 12 is snugly received in the first cavity CV1. The first interface zone 12 can be affixed in the first cavity CV1 by any suitable fixing method, for example via rivets or bolts that pass through aligned openings 230 that are provided in first flanges 210A and 220A and in the first interface zone 12. Additionally or alternatively, the first interface zone 12 can be affixed in the first cavity CV1 by welding. Alternatively, the first interface zone 12 can be integrally affixed in the first cavity CV1 by being integrally formed with the first component 10, in particular by being integrally formed with the first interface zone 12. The first flange arrangement 200A further comprises a first web 215A interconnecting the inner ends of the first flanges 210A and 220A. The first flanges 210A and 220A and the first web 215A co-extend along the system axis SA along the length L of the clamping system 100. The length L is taken parallel to the system axis SA and extends from one longitudinal end LEI to the other longitudinal end LE2 of the clamping system 100. Thus, in at least this example in which the system axis SA is rectilinear, the length L is along a straight line, whereas for example in examples in which the respective system axis is in the shape of an arc, for example, the respective length is along the arc.

[0089] In at least this example, in which the first interface zone 12 is in the form of a flat planar strip or flange, the two first flanges 210A and 220A are also planar.

[0090] In at least some alternative variations of this example, the respective first flange arrangement 200A comprises only one of the first flanges 210A, 220A, and the first component 10, in particular the first interface zone 12, is affixed only to the respective first flange 210A or only to the respective first flange 220A, in a similar manner to the above example, mutatis mutandis.

[0091] In at least this example, the second flange arrangement 200B is a mirror image of the first flange arrangement 200A. Thus, the second flange arrangement 200B, is configured for being affixed to the second component 20, in particular for being affixed to the second interface zone 22 of the second component 20. In at least this example, the second flange arrangement 200B comprises a pair of second flanges 210B and 220B, parallel to one another and separated from one another by a second spacing SP2, defining a second cavity CV2. . While in at least this example, second flanges 210B and 220B parallel to one another, and also parallel to the first flanges 210A and 220A, in at least some alternative variations of this example, the second flanges 210B and 220B can be converging or diverging with respect to one another., and or, can be inclined with respect to the first flanges 210A and 220A.

[0092] In at least this example, the second spacing SP2 corresponds to the second thickness T2, and thus the second interface zone 22 is received in the second cavity CV2. The second interface zone 22 can be affixed in the second cavity CV2 by any suitable fixing method, for example via rivets or bolts that pass through aligned openings 230B (provided in second flanges 210B and 220B) and the second interface zone 22. Additionally or alternatively, the second interface zone 22 can be affixed in the second cavity CV2 by welding. Alternatively, the second interface zone 22 can be integrally affixed in the second cavity CV2 by being integrally formed with the second component 20, in particular by being integrally formed with the second interface zone 22. The second flange arrangement 200B further comprises a second web 215B interconnecting the inner ends of the second flanges 210B and 220B. The second flanges 210B and 220B and the second web 215B co-extend along the system axis SA along the length L of the clamping system 100.

[0093] In at least this example, in which the second interface zone 22 is in the form of a flat planar strip or flange, the two second flanges 21 OB and 220B are also planar.

[0094] In at least some alternative variations of this example, the respective second flange arrangement 200B comprises only one of the second flanges 210B, 220B, and the second component 20, in particular the second interface zone 22, is affixed only to the respective second flange 210B or only to the respective second flange 220B, in a similar manner to the above example, mutatis mutandis.

[0095] Referring in particular to Fig. 3 and Fig. 4, the first flange arrangement 200A further comprises a first shoulder 250A defining a first flange abutment surface 260A. The first abutment surface 260A is non-parallel with respect to the reference longitudinal axis LA. In at least this example, the first flange abutment surface 260A is inclined at a first inclination angle 01 with respect to the reference longitudinal axis LA. In at least this example, the first inclination angle 01 is in the range from just over 0° to just under 90°. More in particular, in at least this example, the first inclination angle 01 is in the range 60° to 89°; or in the range 70° to 89°, or in the range 70° to 80°, or in the range 80° to 89°. In at least the illustrated example, the first inclination angle 01 is any one of 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 80°. In yet other alternative variations of these examples, the first inclination angle 01 is in the range 60° to 90°, for example the first inclination angle 01 is 90°.

[0096] The first flange abutment surface 260A faces generally towards the first flanges 210A, 220A, and generally away from the second flange arrangement 200B, at least in the assembly 50.

[0097] The first shoulder 250A also comprises a first aft surface 255A that faces generally away from the first flanges 210A, 220A, and generally towards from the second flange arrangement 200B, at least in the assembly 50.

[0098] In at least this example, the first shoulder 250A and the first flange abutment surface 260A are coextensive along the length L. However, in at least some alternative variations of this example, the first shoulder 250A and / or the first flange abutment surface 260A are not fully coextensive along the length L. For example, the first shoulder 250A can comprise a series of castellations, indentations or recesses uniformly or non-uniformly arranged along the length L, such that first shoulder 250A, or at least the abutment surface 260A, is not continuous along the length L.

[0099] The first shoulder 250A has a wedge cross-section. In at least this example the abutment surface 260A is nominally flat, since the system axis SA is rectilinear. However, in at least some alternative variations of this example, in which for example the respective system axis is in the shape of an arc, the respective abutment surface 260A is nominally conical, in particular convexly conical.

[0100] As will become clearer herein, the first abutment surface 260A is a load-bearing surface, and configured for being in load-bearing abutment contact with the holding arrangement 300, at least in the engaged configuration EC.

[0101] The first flange arrangement 200A, together with the second flange arrangement 200B and the holding arrangement 300, define an actuation chamber 420 for accommodating at least a portion of the actuation system 400, in the engaged configuration EC, as will become clearer herein. In this connection, the first flange arrangement 200A comprises a shelf 270A, projecting in a general direction parallel to the reference longitudinal axis LA away from the first flanges 210A, 220A and the first shoulder 250A, and towards the second flange arrangement 200B, at least in the engaged configuration EC. The first shelf 270A comprises a first shelf edge 275A.

[0102] The first shoulder 250A and the first aft surface 255A together define a portion of the actuation chamber 420.

[0103] Referring in particular to Fig. 3 and Fig. 5, the second flange arrangement 200B further comprises a second shoulder 250B defining a second flange abutment surface 260B. The second abutment surface 260B is non-parallel with respect to the reference longitudinal axis LA. In at least this example, the second flange abutment surface 260B is inclined at a second inclination angle 02 with respect to the reference longitudinal axis LA. In at least this example, the second inclination angle 02 is in the range from just over 0° to just under 90°. More in particular, in at least this example, the second inclination angle 02 is in the range 60° to 89°, or in the range 70° to 89°, or in the range 70° to 89°, or in the range 70° to 80°, or in the range 80° to 89°. In at least the illustrated example, the second inclination angle 02 is any one of 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 80°.

[0104] In yet other alternative variations of these examples, the second inclination angle 02 is in the range 60° to 90°, for example the second inclination angle 02 is 90°.

[0105] In at least this example, the first inclination angle 01 and the second inclination angle 02 are identical to one another. However, in at least some alternative variations of this example, the first inclination angle 01 and the second inclination angle 02 can be different, i.e. can have different magnitudes, from one another.

[0106] The second flange abutment surface 260B faces generally towards the second flanges 210B, 220B, and generally away from the first flange arrangement 200A, at least in the assembly 50.

[0107] The second shoulder 250B also comprises a second aft surface 255B that faces generally away from the second flanges 210B, 220B, and generally towards the first flange arrangement 200A, at least in the assembly 50.

[0108] In at least this example, the second shoulder 250B and the second flange abutment surface 260B are coextensive along the length L. However, in at least some alternative variations of this example, the second shoulder 250B and / or the second flange abutment surface 260B are not fully coextensive along the length L. For example, the second shoulder 250B can comprise a series of castellations, indentations or recesses uniformly or non- uniformly arranged along the length L, such that the second shoulder 250B, or at least the second abutment surface 260B, is not continuous along the length L.

[0109] The second shoulder 250B has a wedge cross-section. In at least this example the second abutment surface 260B is nominally flat, since the system axis SA is rectilinear. However, in at least some alternative variations of this example, in which for example the respective system axis is in the shape of an arc, the respective second abutment surface 260B is nominally conical, in particular convexly conical.

[0110] As will become clearer herein, the second abutment surface 260B is a load-bearing surface, and configured for being in load-bearing abutment contact with the holding arrangement 300, at least in the engaged configuration EC.

[0111] The second flange arrangement 200B further comprises a second shelf 270B, projecting in a general direction parallel to the reference longitudinal axis LA away from the second flanges 210B, 220B and the second shoulder 250B, and towards the first flange arrangement 200A, at least in the engaged configuration EC. The second shelf 270B comprises a second shelf edge 275B.

[0112] The second shoulder 250B and the second aft surface 255B together define another portion of the actuation chamber 420.

[0113] In at least this example, in the assembly 50, second shelf edge 275B and the second shelf edge 275B are facing one another and separated by a spacing SPX.

[0114] In at least this example, the holding arrangement 300 comprises one holding plate 350 and a respective orthogonal load bearing arrangement 380. However, in at least some alternative variations of this example, the holding arrangement 300 comprises a plurality of holding plates 350, each holding plate 350 having a respective orthogonal load bearing arrangement 380. In examples wherein the holding arrangement 300 comprises a plurality of holding plates 350, the holding plates 350 can be similar to one another, or can be different from one another, generally depending on the form of the system axis SA. For example in examples in which the system axis SA is rectilinear or has a fixed curvature, the respective holding plates 350 can be identical to one another; on the other hand in examples in which the system axis SA has a varying curvature, or different curvatures along different parts of the system axis SA, the precise form of the various holding plates 350 can be different one from the other, and generally correlated to the curvature of the respective portions of the system axis SA corresponding to the individual holding plates 350.

[0115] Referring to Fig. 3 and Fig. 4, the holding plate 350 is configured for being in load bearing and abutting contact with the first flange arrangement 200A and the second flange arrangement 200B, in the engaged configuration EC, and thus prior to actuation of the actuation device 400. In particular, the holding plate 350 is configured for supporting clamping loads between the first flange arrangement 200A and the second flange arrangement 200B in a direction nominally parallel to the reference axis, i.e., in the first direction A, in the engaged configuration EC.

[0116] In at least this example, the holding plate 350 comprises a first wedge element 340A, a second wedge element 340B, and an interconnecting bridge element 340C that mechanically and rigidly connects the first wedge element 340A and the second wedge element 340B at a reference spacing LS therebetween.

[0117] The first wedge element 340A defines a first holding element abutment surface 360A, and the second wedge element 340B defines a second holding element abutment surface 360B.

[0118] The holding plate 350 is configured for providing load-bearing connection between the first flange arrangement 200A and the second flange arrangement 200B, in particular between the first wedge element 340A and the first shoulder 250A, and between the second wedge element 340B and the second shoulder 250B, in the engaged configuration EC.

[0119] Also, and as will become clearer herein, the holding plate 350 is configured for providing load-bearing connection between the first flange arrangement 200A and the second flange arrangement 200B, in particular between the first wedge element 340A and the first shoulder 250A, and between the second wedge element 340B and the second shoulder 250B, in the engaged configuration EC, in which such load bearing is in the first direction A parallel to the reference longitudinal axis LA.

[0120] In particular, the first holding element abutment surface 360A is configured for being in load-bearing and abutting contact with the first flange abutment surface 260A of the first shoulder 250A, in the engaged configuration EC. In such abutting contact, tensile and compressive stresses can be transmitted between the holding plate 350 of the holding arrangement 300 and the first flange arrangement 200A, and thus between the holding arrangement 300 and the first component 10, in the engaged configuration EC. Accordingly, in at least this example, the first holding element abutment surface 360A is complementarity shaped with respect to the first flange abutment surface 260A, such that mechanical contact between the first holding element abutment surface 360A and the first flange abutment surface 260A enables such loads to be transmitted via the mutually abutting surfaces. Thus, the first holding element abutment surface 360A is also inclined at the first inclination angle 01 with respect to the reference longitudinal axis LA, and the first holding element abutment surface 360A is configured for being in load-bearing and abutting contact with the first flange abutment surface 260A at a first contact plane PL1, also inclined at the first inclination angle 01 with respect to the reference longitudinal axis LA.

[0121] Similarly, the second holding element abutment surface 360B is configured for being in load-bearing and abutting contact with the second flange abutment surface 260B of the second shoulder 250B, in the engaged configuration EC. In such abutting contact, tensile and compressive stresses can be transmitted between the holding plate 350 of the holding arrangement 300 and the second flange arrangement 200B, and thus between the holding arrangement 300 and the second component 20, in the engaged configuration EC. Accordingly, in at least this example, second holding element abutment surface 360B is complementarity shaped with respect to the second flange abutment surface 260B, such that mechanical contact between the second holding element abutment surface 360B and the second flange abutment surface 260B enables such loads to be transmitted via the abutting surfaces. Thus, the second holding element abutment surface 360B is also inclined at the second inclination angle 02 with respect to the reference longitudinal axis LA, and the second holding element abutment surface 360B is configured for being in load-bearing and abutting contact with the second flange abutment surface 260B at a second contact plane PL2, also inclined at the second inclination angle 02 with respect to the reference longitudinal axis LA. The first holding element abutment surface 360A and the second first holding element abutment surface 360B are thus generally facing one another along a direction parallel to the reference longitudinal axis LA.

[0122] The reference spacing LS is parallel to the reference longitudinal axis LA, and is sized such as to ensure load-bearing abutting contact between the first wedge element 340A and the first shoulder 250A, and between the second wedge element 340B and the second shoulder 250B, in the engaged configuration EC, and in particular such as to ensure loadbearing abutting contact between the first holding element abutment surface 360A and the first flange abutment surface 260A, and between the second holding element abutment surface 360B and the second flange abutment surface 260B.

[0123] The reference spacing LS is also sized such as to ensure that, in the engaged configuration EC, and in assembly 50, the first component 10 and the second component 20 are in, and are maintained in, a predetermined (i.e., the required) relative spatial dispositions with respect to one another when the clamping system 100 is in the engaged configuration EC.

[0124] In at least this example, the orthogonal load bearing arrangement 380 is configured for providing a resisting force between the respective holding plate 350 and the first flange arrangement 200A, and between the respective holding plate 350 and the second flange arrangement 200B, in a second direction B orthogonal to the reference longitudinal axis LA, in the engaged configuration EC, and to discontinue such a resisting force in the disengaged configuration DEC. However, in at least some alternative variations of this example, the orthogonal load bearing arrangement 380 is configured for providing a resisting force between the respective holding plate 350 and the first component 10, and between the respective holding plate 350 and the second component 20, in the second direction B orthogonal to the reference longitudinal axis LA, in the engaged configuration EC, and to discontinue such a resisting force in the disengaged configuration DEC.

[0125] In at least this example, the orthogonal load bearing arrangement 380 is configured for selectively supporting clamping loads in the second direction B nominally orthogonal to the reference axis LA in the engaged configuration EC, and for selectively terminating supporting said clamping loads in said second direction B in the disengaged configuration DEC. In at least this example, the orthogonal load bearing arrangement 380 is in particular configured for providing resistance for the holding plate 350 in the second direction B, generally orthogonal to the reference longitudinal axis LA, and thus prevent relative movement between the holding plate 350 and each one of the first flange arrangement 200A and the second flange arrangement 200B, as a result of the load bearing contact between the holding plate 350 and each one of the first flange arrangement 200A and the second flange arrangement 200B, in the engaged configuration EC.

[0126] In the engaged configuration EC, the holding plate 350 is in a pre-stressed condition, and induces a holding force FH between the first flange arrangement 200A and the second flange arrangement 200B, in a direction parallel to the reference longitudinal axis LA, via the first contact plane PL1 and the second contact plane PL2. Referring to Fig. 6(a), in the engaged configuration EC, this holding force FH is resisted by the holding plate 350 via respective first and second resistive forces Fl and F2 at and orthogonally to the first contact plane PL1 and the second contact plane PL2, respectively.

[0127] The first resistive force Fl has a first component FHI parallel to the reference longitudinal axis LA, and a second component Fvi orthogonal to the reference longitudinal axis LA, as follows:

[0128] FHI = Fl * sin (01)

[0129] Fvi = Fl * cos (01)

[0130] Similarly, the second resistive force F2 has a first component FH2 parallel to the reference longitudinal axis LA, and a second component Fv2 orthogonal to the reference longitudinal axis LA, as follows:

[0131] FH2 = F2 * sin (02)

[0132] FV2 = F2 * cos (02)

[0133] The respective first components FHI and FH2 are in opposite directions from one another, and parallel to the reference longitudinal axis LA, and thus resist the holding force FH, since the first plane PL1 and the second plane PL2 are converging with respect to one another, and the first inclination angle 01 and the second inclination angle 02 are in mutually opposite directions with respect to the reference longitudinal axis LA. However, the respective second components Fvi and Fv2 are in the same direction, and orthogonal to the reference longitudinal axis LA, and in the engaged configuration EC are resisted by the orthogonal load bearing arrangement 380.

[0134] It is assumed that shear forces between the first holding element abutment surface 360A and the first flange abutment surface 260A, or between the second holding element abutment surface 360B and the second flange abutment surface 260B, are insignificant or minimal as compared with the respective first components FHI and FH2 or the respective second components Fvi and Fv2.

[0135] It is to be noted that in view that the first plane PL1 and the second plane PL2 are converging with respect to one another, and the first inclination angle 01 and the second inclination angle 02 are in mutually opposite directions with respect to the reference longitudinal axis LA, in the disengaged configuration DEC, in which there is an absence of any restraining force (otherwise provided by the orthogonal load bearing arrangement 380 in the engaged configuration EC) resisting the summation of respective second components Fvi and Fv2, there is nothing preventing the holding plate 350 becoming detached from the first flange arrangement 200A and the second flange arrangement 200B, and thus terminating the load-bearing contact between the holding plate 350 becoming detached from the first flange arrangement 200A and the second flange arrangement 200B. This allows the first component 10 and the second component 20 to become disconnected from one another.

[0136] It is to be noted that the clamping system, via the first shelf 270A and the second shelf 270B, can also provide resistance to torsion or bending moments between the first flange arrangement and the second flange arrangement, and thus between the first component and the second component in the engaged configuration in one rotational direction. Similarly, the first wedge element 340A and the second wedge element 340B can provide resistance to torsion or bending moments between the first flange arrangement and the second flange arrangement, and thus between the first component and the second component in the engaged configuration in the opposite rotational direction.

[0137] The hear load bearing arrangement 380 is configured for resisting the orthogonal clamping forces Fvi and Fv2 in the engaged configuration, and for discontinuing such resistance in the disengaged configuration. In at least this example, the orthogonal load bearing arrangement 380 is configured for resisting the orthogonal clamping forces Fvi and Fv2 in shear, i.e., via shear resistive forces FRI and FR2 provided by the orthogonal load bearing arrangement 380 in the engaged configuration.

[0138] In at least this example, the orthogonal load bearing arrangement 380 comprises a first plurality of shear pins 390 that are engaged between the holding plate 350 and the first flange arrangement 200A, and a second plurality of shear pins 390 that are engaged between the holding plate 350 and the second flange arrangement 200B. In at least some alternative variations of this example, the respective first plurality of shear pins 390 can instead be engaged directly between the first component 10 and the holding plate 350, and the respective second plurality of shear pins 390 can instead be engaged directly between the second component 20 and the holding plate 350.

[0139] Referring again to Fig. 3, Fig. 4 and Fig. 5, each holding plate 350, comprises a first lateral plate 320A and a second lateral plate 320B, each projecting laterally away from the interconnecting bridge element 340C, i.e., orthogonally with respect to the reference longitudinal axis LA, and spaced longitudinally from one another.

[0140] The first flange arrangement 200A comprises a first flange plate 240A projecting laterally away from the first flange 210A, i.e., orthogonally with respect to the reference longitudinal axis LA. In the engaged configuration EC, the first flange plate 240A and the first lateral plate 320A are parallel to one another and superposed with one another in a direction parallel to the reference longitudinal axis LA. The first flange plate 240A and the first lateral plate 320A each comprises a plurality of bores, 242A, 322A, respectively, that are mutually aligned in the engaged configuration EC. In the engaged configuration EC, one shear pin 390 is inserted into each aligned pair of bores, 242A, 322A, thereby engaging the first flange plate 240A and the first lateral plate 320A to one another, and thus thereby engaging the first flange arrangement 200A and the holding plate 350 to one another.

[0141] Similarly, the second flange arrangement 200B comprises a second flange plate 240B projecting laterally away from the second flange 210B, i.e., orthogonally with respect to the reference longitudinal axis LA. In the engaged configuration EC, the second flange plate 240B and the second lateral plate 320B are parallel to one another and superposed with one another in a direction parallel to the reference longitudinal axis LA. The second flange plate 240B and the second lateral plate 320B each comprises a plurality of bores, 242B, 322B, respectively, that are mutually aligned in the engaged configuration EC. In the engaged configuration EC, one shear pin 390 is inserted into each aligned pair of bores, 242B, 322B, thereby engaging the second flange plate 240B and the second lateral plate 320B to one another, and thus thereby engaging the second flange arrangement 200B and the holding plate 350 to one another.

[0142] The plurality of shear pins 390 are configured for supporting in shear the summation of the respective second components Fvi and Fv2 acting on the holding plate 350 in the engaged configuration EC via shear resistance forces FRI and FR2. Furthermore, the plurality of shear pins 390 are configured for shearing off when subjected to a predetermined orthogonal force SF, i.e.. in the form of a shearing along the second direction B parallel to a reference transverse axis TA, thereby terminating resistance to the summation of the respective second components Fvi and Fv2 acting on the holding plate 350 in the disengaged configuration DEC.

[0143] It is to be noted that the mechanical properties of the first flange arrangement 200A, the second flange arrangement 200B, and of the holding plate 350 are such that these components retain mechanical integrity in the disengaged configuration, and thus activation of the actuator device 400 serves to mechanically destroy only the shear pins to thereby enable the disengaged configuration to occur.

[0144] The reference longitudinal axis LA and the reference transverse axis TA are nonparallel with respect to one another. In particular, the reference transverse axis TA is generally orthogonal to the reference longitudinal axis LA.

[0145] However, it is to be noted that in at least some alternative variations of these examples, the orthogonal load bearing arrangement 380 is configured for resisting the orthogonal clamping forces Fvi and Fv2 in tension, i.e., via tensile resistive forces FRI and FR2 provided by the orthogonal load bearing arrangement 380 in the engaged configuration. For example, and referring to Fig. 11, such tensile forces can be provided by tensile pins or bolts 390A arranged between the holding plate 350 and each one of the first flange arrangement 200A and the second flange arrangement 200B, in which, in the disengaged configuration, the tensile pins or bolts are selectively fractured longitudinally (parallel to the second direction B) by the force SF, thereby disengaging the holding pate from each one of the first flange arrangement and the second flange arrangement. In such examples the pins or bolts can be aligned with the second direction B, i.e., the direction of the orthogonal clamping forces Fvi and Fv2.

[0146] Furthermore, it is to be noted that in at least some alternative variations of these examples, the orthogonal load bearing arrangement 380 is configured for resisting the orthogonal clamping forces Fvi and Fv2 in compression, i.e., via compressive resistive forces FRI and FR2 provided by the orthogonal load bearing arrangement 380 in the engaged configuration. For example, and referring to Fig. 12, such compressive forces can be provided by a clutch arrangement arranged between the holding plate 350 and each one of the first flange arrangement 200A and the second flange arrangement 200B. Such a clutch arrangement can include a plurality of clutch elements 390B, each clutch element 390B having a respective ball element 391 that in the engaged configuration is pressed against a respective indentation 392 in the respective first lateral plate 320A or second lateral plate 320B, via a spring 393. The spring 393 and ball 392 can be prestressed to any desired compressive stress via turning bolt 394. In the disengaged configuration, clutch elements 390B operate such that the balls 392 are pressed back into the well 395 and against the compressive force of the springs 393, in a direction parallel to the reference longitudinal axis LA, responsive to the orthogonal force SF being applied to the holding plate 350, thereby disengaging the holding pate from each one of the first flange arrangement and the second flange arrangement. In such examples the holding plate is non-destructively disengaged with respect to the first flange arrangement and the second flange arrangement.

[0147] The predetermined orthogonal force SF is selectively provided by the actuator device 400, as will become clearer herein.

[0148] It is to be noted that the said actuator device 400 is mechanically distinct from the holding plate 350, the first flange arrangement 200A and the second flange arrangement 200B. In other words, the actuator device 400 is not necessarily mechanically coupled with the holding plate 350, the first flange arrangement 200A and the second flange arrangement 200B at least in the engaged configuration EC.

[0149] The actuator device 400 operates to selectively apply a force to the holding plate 350 in the second direction B parallel to the reference transverse axis TA, sufficient to shear the plurality of shear pins 390. As will become clearer herein, and referring to Fig. 7(a) and Fig. 7(b), and also to Fig. 6(a) and Fig. 6(b), the actuator device 400 comprises a first configuration TCI and a second configuration TC2. In the first configuration the actuator device 400 comprises a first transverse dimension DI in a second direction B parallel to the reference transverse axis TA. In the second configuration the actuator device 400 comprises a second transverse dimension D2 in the second direction B, the second transverse dimension D2 being greater than the first transverse dimension DI. Furthermore, a transverse displacement AD can be defined as a difference between the second transverse dimension D2 and the first transverse dimension DI. In the engaged configuration EC, the actuator device 400 is in the first configuration TCI, and in a mutually abutting relationship or in a transverse spaced relationship with respect to the mounting plate 350. In the disengaged configuration DEC, the actuator device 400 is in the second configuration TC2. The actuator device 400 is configured for selectively applying to the mounting plate 350 a force SF in the second direction B to thereby displace the mounting plate and concurrently apply a shearing force to the shearing pins 390, responsive to a change in configuration of the actuator device 400 from the first configuration TCI to the second configuration TC2, to thereby transition the clamping system 100 from the engaged configuration EC to the disengaged configuration DEC.

[0150] Referring also to Fig. 3, the actuator device 400 is in the form of an expansion tube, in at least this example in the form of a pyrotechnic expansion tube, and comprises a tube element 450 configured for shape-morphing from the first tube configuration TCI having the first transverse dimension DI (also referred to interchangeably hereon as the first tube dimension DI) parallel to the second direction B, and a second tube configuration TC2 having the second transverse dimension D2 (also referred to interchangeably herein as the second tube dimension D2) parallel to the second direction B. In particular, the first tube dimension DI and the second tube dimension D2 correspond to parts of the tube element 450 at or in proximity to the holding plate 350.

[0151] The second tube dimension D2 is significantly greater than the first tube dimension DI.

[0152] The second transverse dimension TCI is sufficient to enable the actuator device 400 to displace the holding plate 350 in the second direction B to thereby become disengaged with respect to the first flange arrangement 200A and the second flange arrangement 200B, and thereby transit the clamping system 100 to the disengaged configuration DEC.

[0153] For example, in the first tube configuration TCI, the tube element 450 has a generally flattened circle cross-sectional shape, while in the second tube configuration TC2, the tube element 450 has a generally circular cross-sectional shape.

[0154] According to an aspect of the presently disclosed subject matter, the actuator device 400 is configured for providing such a second tube dimension D2, in particular a tube wall displacement AD (= D2 - DI) that is sufficient to concurrently shear the shear pins 390 and to eject the holding plate 350 from the first flange arrangement 200A and the second flange arrangement 200B, such that the first wedge element 340A and the second wedge element 340b completely clear the first shoulder 250A and the second shoulder 250B in the second direction B.

[0155] In other words, the value of AD can be equal to or greater than required lateral displacement of the holding plate 350 along the second direction B, such as to ensure the first wedge element 340A and the second wedge element 340b completely clear the first shoulder 250A and the second shoulder 250B in the second direction B.

[0156] In at least this example, the actuator device 400 is configured for providing the required second tube dimension D2 in a predetermined short time sufficient to concurrently cause the respective holding plate 350 to be moved from the engaged configuration EC to the disengaged configuration DEC. For example, such a short time period can be in the order of microseconds, or in the range of a few milliseconds (for example 1 to 10 milliseconds) to a few microseconds (for example 1 to 10 microseconds), or in the range between 1 microsecond to 100 microseconds. This enables the actuator device 400 to operate to effectively disassemble the clamping system 100, enabling the first component 10 and the second component 20 to become uncoupled very quickly.

[0157] In at least this example, the actuator device 400 comprises a pyrotechnic system (not shown) for selectively morphing the shape of the tube element 450 from the first tube configuration TCI to the second tube configuration TC2 responsive to a suitable activation command. For example, such an activation command can include an electrical, electronic or digital signal, from a suitable controller, or can include a pyrotechnic shock.

[0158] The tube element 450 comprises an internal lumen 455, and the pyrotechnic system 490 comprises a linear explosive assembly (not shown) accommodated in the internal lumen 455.

[0159] The tube element 450 is accommodated in the actuation chamber 420, defined by the first flange arrangement 200A, the second flange arrangement 200B and the holding pate 350. The first shelf 270A and the second shelf 270B together provide a mechanical restraint to the tube element 450, so that the full dimensional change from DI to D2 occurs in the second direction B towards the holding plate 350.

[0160] The size and potency of the pyrotechnic charge will generally depend on the shear force that is required to be generated to shear the shear pins 390.

[0161] On the other hand, the size and number of shear pins 390, and thus the magnitude and potency of the pyrotechnic charge, will depend on the first inclination angle and the second inclination angle, and on the magnitude of the axial force that is required to maintain engaged the first component 10 and the second component 20 up to when it is required for the clamping system 100 to transit to the disengaged configuration DEC.

[0162] Without being bound to theory, when the actuator device 400 is selectively activated, the respective command signal detonates the linear explosive assembly of the pyrotechnic system 490, resulting in an expansion and resultant morphing of the tube element 450 from a relatively small cross-sectional area to a relatively large cross- sectional area, thereby increasing the transverse dimension from DI to D2 and in the process displacing the holding plate 350 in the second direction B and shearing the shearing pins 390. The amount and type of the explosive materials in the liner explosive assembly can be such as to ensure sufficient deformation of the tube element 450, while not rupturing or otherwise destroying the tube element 450 itself. This can result in the actuator device 400 not contributing to particulate debris after the first component 10 and the second component 20 are uncoupled.

[0163] It is to be noted that at least in some alternative variations of this example, the tube element 450 can be flexible and / or elastic, and coupled with a pneumatic source or hydraulic source, such that activation of the actuator device in a pressure build up in the lumen 455, thereby resulting in an expansion and resultant morphing of the tube element from a relatively small cross-sectional area to a relatively large cross-sectional area, thereby increasing the transverse dimension from DI to D2, and in the process similarly causing displacement of the holding plate 350 in the second direction B and shearing the shearing pins 390.

[0164] In at least this example, the tube element 450 can be in abutting contact, or spaced by a small spacing, with respect to the respective holding plate 350.

[0165] In at least some examples, the clamping system 100 comprises a plurality of holding plates 350, wherein all the holding plates 350 are operatively coupled with respect to a single actuator device 400. In other words, a single actuator device 400 is provided, for concurrently actuating all the holding plates 350. In this manner, all the holding plates 350 can be concurrently transitioned to disengaged configuration DEC to thereby ensure a clean uncoupling between the first component 10 and the second component 20.

[0166] The number of holding plates 350 included in any particular application of the clamping system 100 can generally depend on the mechanical loads expected between the first component 10 and the second component 20, and on the mechanical properties of the various components of the clamping system 100, including the mechanical properties of the holding plates 350 themselves. In this manner, the number of required holding plates 350 can be matched to any particular application in a relatively straightforward manner, and thus allows the same type of clamping system 100 to be used for many and varied applications.

[0167] In operation of the clamping system 100, when it is required for the first component 10 and the second component 20 to become uncoupled, a suitable command signal is transmitted to the actuator device 400, whereupon the pyrotechnic system morphs the tube element 450 to thereby provide the required shearing force SF to the respective orthogonal load bearing arrangement 380, the shearing force SF being concurrently applied to all the mounting plates 350 in the respective directions B. In such a case, each second direction B can be radial, originating from the reference longitudinal axis LA, for example. The shear force SF transits each clamping system 100 to the respective disengaged configuration DEC, completely disengaging the first flange arrangement 200A from the second flange arrangement 200B, and thereby terminating the mechanical force that formerly maintained the first component 10 axially engaged with the second component 20, along the first direction A.

[0168] As schematically illustrated in Fig. 7(a) and Fig. 7(b), the clamping system 100 can optionally further comprise a restrainer 800 configured for mechanically coupling the respective mounting plate 350 to only one of the first component 10 or the second component 20. Thus for example each mounting plate remains mechanically connected to the second component 20 or to the first component 10, after the second component 20 is disengaged with respect to the first component 10. This can provide the benefit of minimizing or avoiding generating many independent debris elements resulting from operation of the clamping system 100.

[0169] Referring to Fig. 3, in another example, the respective system axis SA is circular, having the center intersecting the reference longitudinal axis LA. In such an example, a plurality of clamping systems 100 can be provided for clamping the respective first component 10 and the respective second component 20 together, which can be cylindrical or frusto-conical for example. Each such clamping system 100 can be similar to the clamping system 100 of Figs. 1 to 7(b) as disclosed herein mutatis mutandis, with the main difference that in the example of Fig. 10 the respective system axis SA is curved with a fixed curvature, while in the example of Figs. 1 to 7(b) the respective system axis SA is rectilinear. Thus, in the example of Fig. 1, the respective first and second flange arrangements, as well as the respective holding plates, are curved rather than flat.

[0170] Furthermore, in the example of Fig. 3, the respective clamping systems 100 cover only part of the circumferential periphery of the first component 10 and the second component 20. The various clamping systems 100 are equi-spaced circumferentially around the periphery, and there is a spacing between each pair of adjacent clamping systems 100. In such cases, a single actuation device 400 can optionally be provided for actuating all the separate clamping systems 100, or, each clamping system 100 can have its own separate actuation system 400.

[0171] However, in alternative variations of this example, the full periphery can be covered with clamping systems 100. For any particular application of the example OF Fig. 3, the number of clamping systems 100 provided will generally depend on the magnitude of the loads expected to have to be supported by the totality of clamping systems 100 in the respective engaged configuration EC.

[0172] Referring again to the example of Fig. 9(a) and Fig. 9(b), for example, in at least some other examples, in which the system axis SA is not rectilinear or of fixed curvature, a number of separate clamping systems 100 can be provided, each being shaped in conformity with the shape of the respective portion of the system axis SA.

[0173] It is thus evident from the above, that at least the above examples of the clamping system do not require tangential or circumferential tension loads to be applied at the interface portion between the first component and the second component. Without being bound to theory, inventors consider that the clamping system of the presently disclosed subject matter does not require large circumferential loads to be applied at the interface portion, and thus there is less stored potential energy during disengagement than, for example a Marman based system, which stored energy could otherwise induce shock and / or vibration when released at disengagement.

[0174] It is also evident that at least the above examples of the clamping system also provide resistance to torsion or bending moments between the first flange arrangement and the second flange arrangement, and thus between the first component and the second component in the engaged configuration.

[0175] In the method claims that follow, alphanumeric characters and Roman numerals used to designate claim steps are provided for convenience only and do not imply any particular order of performing the steps.

[0176] Finally, it should be noted that the word “comprising” as used throughout the appended claims is to be interpreted to mean “including but not limited to”.

[0177] While there has been shown and disclosed examples in accordance with the presently disclosed subject matter, it will be appreciated that many changes may be made therein without departing from the scope of the presently disclosed subject matter as set out in the claims.
