Description

[0001] The present invention relates to a modular ammunition launching system, of the type comprising at least one ammunition receiving box forming at least one firing channel for a munition emitting a pyrotechnic jet in a longitudinal direction, the modular system further comprising at least one attenuation device.

[0002] The invention also relates to a naval platform comprising at least one such modular munitions launching system.

[0003] Such modular munitions launching systems are typically mounted on a vessel, such as a naval platform or a vehicle, and are configured to allow the launch of different types of munitions in order to adapt the vessel's or vehicle's response to a threat or its environment. For example, such modular launching systems are suitable for the selective launch of rockets, missiles, or even attack and / or observation aircraft, such as drones.

[0004] When certain munitions are fired, they emit a pyrotechnic jet outward from the modular ammunition launch system. This pyrotechnic jet has a high temperature and pressure, resulting in the high-speed ejection of solid or molten particles.

[0005] Due to the limited space available on a naval platform, the pyrotechnical discharge from munitions impacts one or more surfaces of components or walls surrounding the modular launch system in a concentrated area, resulting in damage to these surfaces, especially during repeated firings. Furthermore, the pyrotechnical discharge from a single munition can damage other munitions stored in the receiving caisson.

[0006] One of the aims of the invention is to overcome these drawbacks by proposing a modular ammunition launching system that mitigates the effect of the pyrotechnic jet generated when firing a munition.

[0007] To this end, the invention relates to a modular munitions launching system of the aforementioned type, in which said attenuation device comprises at least one jet-breaking element arranged to separate the pyrotechnic jet from the munition into at least two sub-jets, each extending in a different direction from the other sub-jet and from the longitudinal direction.

[0008] By breaking up the pyrotechnic jet of a munition and dividing it into several sub-jets, it is possible to diffuse the impact of the pyrotechnic jet across a surface, thus preventing it from being concentrated in a single area. Changing the direction of the sub-jets also has the advantage of creating pressure losses within each sub-jet. These pressure losses result in a deceleration of the gas and particle flow, thereby reducing surface damage. Furthermore, the effect of each sub-jet on the impacted area is attenuated compared to the entire pyrotechnic jet. In addition, the attenuation device allows for the evacuation or trapping of solid or molten particles contained within the pyrotechnic jet, preventing them from damaging other munitions received in the receiving container.

[0009] The modular launching system according to the invention may comprise one or more of the following features, considered alone or in any technically feasible combination: the attenuation device comprises a main body including a tubular wall extending along an axis substantially parallel to the longitudinal direction between an inlet of the pyrotechnic jet and an outlet of the pyrotechnic jet, the jet-breaking element extending at least in or opposite the outlet along the longitudinal direction and comprising at least one deflection surface inclined with respect to the axis of the main body; the jet-breaking element comprises a plurality of blades extending around the axis of the main body, each blade comprising a deflection surface extending from the axis of the main body to the tubular wall of the main body, the blades being spaced apart from each other and defining between them a plurality of channels for the passage of the sub-jets of the pyrotechnic jet at the outlet of the main body;The passage channels direct the sub-jets in divergent directions away from the axis of the main body along the longitudinal direction from the inlet to the outlet of the main body; the deflection surface of the jet-breaking element has a substantially conical shape extending along the axis of the main body, said deflection surface extending opposite the outlet of the main body and flaring out in the direction from the inlet to the outlet of the main body; the jet-breaking element is mounted on a shaft extending in the main body along the axis of said main body, the jet-breaking element being movable in translation on said shaft between a closed position, in which the jet-breaking element closes the outlet of the main body, and an open position, in which the jet-breaking element is away from the outlet of the main body, the jet-breaking element moving from the closed position to the open position under the effect of the pyrotechnic jet;The attenuation device includes a constraint element forcing the jet-breaking element towards the closed position; the receiving chamber forms a plurality of ammunition firing channels, the jet-breaking element of the attenuation device extending in the path of the pyrotechnic jets from the munitions placed in the firing channels, each pyrotechnic jet being separated into at least two sub-jets, each extending in a direction different from the other sub-jet and from the longitudinal direction of said jet-breaking element; the jet-breaking element includes at least two deflection surfaces extending in directions of deflection different from each other and from the longitudinal direction, each deflection surface guiding one of the sub-jets of the pyrotechnic jets along their direction of deflection.

[0010] According to another aspect, the invention relates to a naval platform comprising at least one modular munitions launching system as described above.

[0012] With reference to the Fig. 1 A modular munitions launch system 1 is described, comprising primarily a chassis 2 and at least one munitions receiving pod 4. Such a modular launch system 1 is, for example, installed on a naval platform, particularly one used for military purposes, such as a naval vessel, a warship, or the like. It is understood, however, that the modular system 1 is also suitable for installation on other types of platforms, such as a land-based military vehicle or a fixed naval or land-based vessel. Such a modular launch system 1 is designed to launch or fire munitions at a distance from the platform on which it is installed, including different types of munitions depending on the target(s) identified around the platform. These munitions include, for example, rockets, missiles, and other types of projectiles. They also include attack and / or observation aircraft, such as drones.

[0013] The chassis 2 is arranged to receive the receiving box 4 so that the ammunition contained in the receiving box 4 can be fired when the receiving box 4 is received in the chassis 2. For this purpose, the chassis 2 defines at least one housing accommodating the receiving box 4. According to one embodiment, the chassis 2 is arranged to receive several receiving boxes 4 and thus defines as many housings 6.

[0014] The frame 2, for example, has a substantially parallelepiped shape and is delimited by a plurality of walls defining the dwelling(s). More specifically, the frame 2 extends along a longitudinal direction L, corresponding to the length of the frame 2, a transverse direction T, substantially perpendicular to the longitudinal direction L and corresponding to the width of the frame 2, and along an elevation direction Z, substantially perpendicular to the longitudinal direction L and the transverse direction T and corresponding to the height of the frame 2. The frame 2 is delimited by a lower wall 6 and an upper wall 8 separated from each other along the elevation direction Z, and by two lateral walls 10 separated from each other along the transverse direction T and connecting the lower wall 6 and the upper wall 8. The frame 2 is open at at least one of its longitudinal ends so as to provide access to the dwelling(s) 6.According to one embodiment of the . Fig. 1 , chassis 2 includes two lower housings and two upper housings 6 to receive four receiving boxes 4.

[0015] When one or more receiving pods 4 are received in the corresponding housing(s), the munitions can be fired from the open longitudinal end of the chassis 2. Advantageously, the firing direction of these munitions is adjustable relative to the platform on which the modular launch system 1 is installed. For this purpose, the modular launch system 1 includes, for example, a base 12 on which the chassis 2 is mounted in a movable rotational manner around a first axis of rotation R1 extending along the transverse direction T. Such rotation makes it possible to adjust the firing direction along the elevation direction Z. In other words, this rotation makes it possible to adjust the firing angle of the munitions, for example, relative to the deck of the naval platform on which the modular launch system 1 is installed.In one embodiment, the base 12 is itself mounted to rotate about a second axis of rotation R2 extending along the elevation direction Z. This rotation allows the firing direction of the munitions to be oriented transversely, i.e., to the right or left of the platform receiving the modular launching system 1. The base 12, for example, has the shape of a fork comprising two arms 14 spread apart along the transverse direction T and receiving the chassis 2 between them. Each side wall 10 of the chassis 2 is articulated to one of the arms 14 about the first axis of rotation R1, and the arms 14 are mounted on a base 16 to rotate about the second axis of rotation R2, the base 16 being fixed to the platform receiving the modular launching system 1.

[0016] The ammunition receiving compartment 4 is designed to receive ammunition 20 of a certain type, such as rockets or missiles as described previously. For this purpose, the receiving compartment 4 has the shape of a box, for example, a substantially parallelepiped shape, defining one or more firing channels 18, each firing channel 18 receiving one round of ammunition 20 (only one is shown in the diagram). Fig. 1 ) ready to be fired. When the receiving pod 4 is received in a housing of the chassis 2, the firing channel 18 opens outwards from the modular launch system 1 at the open longitudinal end of the chassis 2, as shown in the Fig. 1 .

[0017] Each firing channel 18, for example, has a substantially tubular shape extending along the longitudinal direction L. From one receiving box 4 to another, the firing channels 18 are not necessarily identical, but are adapted, in particular in terms of dimensions, more specifically diameter, to the munitions 20 received in the firing channels 18.

[0018] At least some of the munitions 20 are propelled, for example by means of a propellant 22, resulting in the generation of a pyrotechnic jet 24 in the firing channels 18 receiving these munitions during firing. In a firing channel 18, such a pyrotechnic jet 24 extends along the longitudinal direction L opposite the head of the munition 20; that is, the pyrotechnic jet 24 is directed towards a rear end 26 of the firing channel 18 opposite a mouth 28 of the firing channel 18 through which the munition 20 is fired. The pyrotechnic jet 24 is formed, for example, of combustion gases at high temperature and high pressure, the gas further containing solid or molten particles.Therefore, this pyrotechnic jet 24 is evacuated through the rear end 26 of the firing channel 18 and impacts the surface 30 located opposite the modular launch system 1 on the opposite side of the mouth 28, for example a wall or the deck of the naval platform on which the modular launch system 1 is installed.

[0019] To prevent damage to this surface 30 from the pyrotechnic jet, the modular launching system 1 includes at least one attenuation device 32 arranged to break up the pyrotechnic jet 24, i.e., to separate this jet into at least two sub-jets 34 whose impact on the surface 30 is reduced compared to the pyrotechnic jet 24 as a whole. To this end, the attenuation device 32 includes at least one jet-breaking element 35 arranged to separate the pyrotechnic jet 24 extending along the longitudinal direction L into at least two sub-jets 34, each extending in a direction different from the other sub-jet 34 and from the longitudinal direction L, as shown in the figure. Fig. 4 The change in direction of the sub-jets 34 also has the advantage of creating pressure losses in each sub-jet. These pressure losses result in a deceleration of the gas and particle flow, and therefore a reduction in damage to the surface 30.

[0020] According to the embodiments shown on the Figs. 2 à 6 The modular launch system 1 includes a mitigation device 32 per firing channel 18, while according to the embodiments of Figs. 7 And 8 which will be described later, the modular launch system 1 includes a damping device 32 for a plurality of firing channels 18.

[0021] A mitigation device 32 according to the embodiment shown in the Figs. 2 And 3 will now be described.

[0022] The attenuation device 32 comprises a main body 36 including a tubular wall extending along an axis substantially parallel to the longitudinal direction L between an inlet 38 of the pyrotechnic jet 24 and an outlet 40 of the pyrotechnic jet 24. The main body 36 has, for example, a diameter substantially equal to that of a firing channel 18, and the inlet 38 of the pyrotechnic jet 24 is positioned opposite the rear end 26 of the firing channel 18, such that the pyrotechnic jet 24 exiting through the rear end 26 of the firing channel 18 enters the main body 36 through the inlet 38 and is guided within the main body 36 to the outlet 40 of the pyrotechnic jet 24. The main body 36 and the firing channel 18 are, for example, more specifically arranged so that the entire pyrotechnic jet 24 enters the main body 36.For this purpose, the main body 36 is, for example, mounted directly on the rear end 26 of the firing channel 18 or is placed immediately opposite the rear end 26, for example by being pressed against it. According to the embodiment of the... Fig. 2 , each firing channel 18 opens into a attenuation device 32, the main bodies 36 of these attenuation devices 32 being mounted on one or more plates 42 mounted on the chassis 2 and placed against a receiving box 4 on the rear end 26 side of the firing channels 18. Such an assembly allows the attenuation devices 32 to be placed immediately at the rear end 26 of the firing channels 18 without mechanical connection between the receiving box 4 and the attenuation devices 32, which facilitates the extraction of the receiving box 4 from the chassis 2 during reloading operations or replacement of the receiving box 4.

[0023] The jet-breaking element 35 extends at least in or opposite the outlet 40 in the longitudinal direction L and includes at least one deflection surface 44 inclined with respect to the axis of the main body 36. The shape of such a deflection surface 44 is arranged to deflect the parts of the pyrotechnic jet 24 flowing along this surface with respect to the longitudinal direction L so as to form at least two sub-jets 34 extending in two different directions from each other and different from the longitudinal direction L.

[0024] Depending on the method of implementation of Figs. 2 And 3 The jet-breaking element 35 comprises several deflection surfaces 44 extending in different directions within the main body 36 so as to deflect different parts of the pyrotechnic jet 24 in different directions. For this purpose, as particularly visible on the Fig. 3 The jet-breaking element 35 comprises a plurality of blades 46 extending around the axis of the main body 36, each blade 46 comprising a deflection surface 44 extending from the axis of the main body 36 to the tubular wall of the main body 36. The blades 46 are spaced apart from each other and define between them a plurality of passage channels for the sub-jets 34 of the pyrotechnic jet 24 to the outlet 40 of the main body 36. The different passage channels extend in different directions so that the sub-jets 34 exiting these passage channels are oriented in these different directions, which are also different from the longitudinal direction L. Thus, the sub-jets 34 are oriented in divergent directions away from the axis of the main body 36 to the outlet 40 of the main body 36.The blades, for example, have curved deflection surfaces 44 that are substantially parallel to each other, so as to present a corolla shape at the outlet 40 of the main body 36, the blades forming the "petals" of the corolla and the passage channels extending between these different petals. It is understood that the shape of the blades 46 shown in the figure... Fig. 3 is given as an example and other forms are conceivable. In particular, on the Fig. 3 , all the blades have an identical shape, but blades with different shapes from each other can also be considered.

[0025] According to one embodiment, the blades 46 extend substantially over the entire length of the main body 36, from the inlet 38 to the outlet 40 thereof, and form a spiral around the axis of the main body 36.

[0026] Depending on the method of implementation of Figs. 5 And 6Apart from the jet-breaking element 35, the attenuation device 32 has the same structure as that of the embodiment of the Figs. 2 And 3 Thus, the attenuation device 32 also comprises a main body 36 including a tubular wall with a diameter substantially equal to that of a firing channel 18, and each firing channel 18 is provided with an attenuation device 32. Only the differences between the attenuation device 32 and the embodiment of the Figs. 5 And 6 compared to that of Figs. 2 And 3 will now be described.

[0027] The deflection surface 44 of the jet-breaking element 35 has a substantially conical shape extending along the axis of the main body 36 opposite the outlet 40 of the main body 36. The deflection surface 44 widens in the direction from the inlet 38 to the outlet 40 of the main body 36; that is, its diameter increases with distance from the outlet 40 of the main body 36. Thus, the pyrotechnic jet 24 flowing along the deflection surface 44 "spreads out" in a plurality of directions diverging from the longitudinal direction L in the direction from the inlet to the outlet of the main body 36, as shown in the diagram. Fig. 4 In other words, the pyrotechnic jet 24 separates into an infinite number of sub-jets 34 which move away from each other as they move away from the outlet 40 of the main body 36.

[0028] As most particularly visible on the Fig. 6 The jet-breaking element 35 is, for example, mounted on a shaft 48 extending into the main body 36 along the axis of the main body 36. The shaft 48 is, for example, connected to the tubular wall of the main body 36 by a plurality of arms 50 extending substantially radially from the tubular wall to the shaft 48. The shaft 48 projects out of the outlet 40 of the main body 36 in the longitudinal direction L, and the jet-breaking element 35 is mounted at the end of the shaft 48 so as to form a passage between the outlet 40 of the main body 36 and the deflection surface 44 of the jet-breaking element 35.

[0029] According to one embodiment, the jet-breaking element 35 is movable in translation along the longitudinal direction L on the shaft 48 between a closed position (not shown), in which the jet-breaking element 35 blocks the outlet 40 of the main body 36, and an open position ( Figs. 5 And 6), in which the jet-breaking element 35 is moved away from the outlet 40 of the main body 36 and defines the aforementioned passage between the outlet 40 and the deflection surface 44. The movement of the jet-breaking element 35 from the closed position to the open position is triggered when the ammunition present in the corresponding firing channel 18 is fired under the effect of the pyrotechnic jet 24 pushing on the deflection surface 44 of the jet-breaking element 35. A constraint element 52 can further be arranged to constrain the jet-breaking element 35 towards its closed position so as to return the jet-breaking element 35 to the closed position after the pyrotechnic jet 24 ceases to apply a force on the deflection surface 44 moving the jet-breaking element 35 towards the open position.The constraint element 52 is for example formed by a helical spring extending around the shaft 48 and applying a force on the jet-breaking element 35 in the longitudinal direction L in the direction from the outlet 40 to the inlet 38 of the main body, as shown in the . Figs. 5 And 6 . Thus, the attenuation device 32 according to this embodiment acts as a valve evacuating and dispersing the pyrotechnic jet 24 during the firing of a munition 20.

[0030] The embodiments represented on the Figs. 7 And 8 , in which the same attenuation device 32 is used for a plurality of firing channels 18 will now be described.

[0031] According to these embodiments, several firing channels 18, or even all the firing channels 18 of one or more receiving pods 4, open into the main body 36 of the attenuation device 32, the shape of which is arranged accordingly. Thus, the main body 36 is, for example, formed by a frame, or a structure, mounted on the longitudinal end of the chassis 2 opposite the opening through which the munitions 20 exit the modular launching system 1 during firing.

[0032] According to these embodiments, the jet-breaking element 35 of the attenuation device 32 extends in the path of the pyrotechnic jets 24 from the munitions 20 placed in the firing channels 18 opening into the main body 36. Each pyrotechnic jet 24 is then separated into at least two sub-jets 34, each extending in a different direction from the other sub-jet and from the longitudinal direction L, by the same jet-breaking element 35 common to the different pyrotechnic jets 24. The deflection surface(s) 44 extend, for example, in the transverse direction T and in the elevation direction Z across the main body 36, and their shape is arranged so that all the pyrotechnic jets 24 meet and flow along a deflection surface 44 and separate into two or more sub-jets 34 extending in different directions from each other and from the longitudinal direction L.Thus, the jet-breaking element 35 comprises at least two deflection surfaces 44 extending along different deflection directions from each other and from the longitudinal direction, each deflection surface 44 guiding one of the sub-jets 34 of the pyrotechnic jets 24 according to their deflection direction.

[0033] According to the embodiment shown in the Fig. 7 The jet-breaking element 35 comprises a plurality of deflection surfaces 44 curved upwards and downwards along the elevation direction Z so as to disperse the sub-jets 34 along the elevation direction Z. More particularly, according to the example of the Fig. 7 The deflection surfaces 44 extending opposite one or more upper rows of firing channels 18 are curved upwards in the direction from the inlet 38 to the outlet 40 and the deflection surfaces 44 extending opposite one or more lower rows of firing channels 18 are curved downwards in the direction from the inlet 38 to the outlet 40. Thus, the upward-oriented deflection surfaces 44 form channels between them directing the pyrotechnic jets 24 upwards and the downward-oriented deflection surfaces 44 form channels between them directing the pyrotechnic jets 24 downwards.

[0034] According to the embodiment shown in the Fig. 8 The jet-breaking element 35 comprises a plurality of deflection surfaces 44, each including at least one change of direction from the inlet to the outlet of the main body 36. Thus, each deflection surface 44 comprises, for example, a first segment oriented upwards along the elevation direction Z and a second segment oriented downwards along the elevation direction Z. Each deflection surface 44 therefore has the shape of a downward-facing V. The deflection surfaces 44 then form channels oriented first upwards and then downwards. This shape promotes the bursting of the pyrotechnic jets 24 in different directions when they strike the deflection surfaces 44. Furthermore, the channels, by changing direction, form particle traps, in which the solid or molten particles contained in the pyrotechnic jets 24 are retained when the pyrotechnic jets 2 circulate through the channels.

[0035] It is worth noting again that the deflection surface shapes 44 shown on the Figs 7 And 8 are given only as examples and other forms can be considered.

[0036] By splitting the pyrotechnic jets 24 into several sub-jets 34 extending in different directions, the attenuation device(s) 32 prevent the concentration of each pyrotechnic jet 24 in a small area relative to the modular launching system 1. Thus, the impact zone of each pyrotechnic jet 24 is spread out, reducing its harmful effect on the affected wall(s). Furthermore, the pyrotechnic jet 24 from a munition 20 is efficiently evacuated so that it does not risk damaging munitions 20 present in other firing channels 18.
