[0001] The present invention relates to the field of probe testing, particularly of Pitot probes.

[0002] The invention relates more specifically to an adapter for a test device. State of the art

[0003] Adapters for Pitot probe test devices are known in the prior art, for example the adapter described in document US3518870.

[0004] There is a general need to improve the robustness, efficiency, and compatibility of currently known adapters. Description of the invention

[0005] The invention relates to an adapter for connecting a test device to a probe, in particular a Pitot type probe.

[0006] The adapter of the invention generally comprises a body and components having structural and functional characteristics which include, but are not limited to, those described below in the context of different aspects of the invention which can be implemented independently of each other.

[0007] According to a first aspect of the invention, the adapter may include a receiving member housed in the body, the receiving member comprising a central orifice which preferably extends along a longitudinal axis and lateral orifices.

[0008] In one embodiment, the receiving organ forms a cavity intended to receive one end of the probe.

[0009] The cavity can be configured to establish fluidic communication between said central orifice of the receiving organ and a central Pitot duct of the probe.

[0010] Alternatively or complementarily, the cavity can be configured to establish fluidic communication between said lateral orifices of the receiving organ and the respective lateral orifices of the probe.

[0011] In one embodiment, the receiving organ comprises recesses and surface elements delimiting said cavity, the recesses preferably being spaced circumferentially from each other around said longitudinal axis, each of said surface elements extending circumferentially between two of said respective recesses.

[0012] In one embodiment, each of said lateral orifices of the receiving organ opens onto one of said respective surface elements.

[0013] In one embodiment, the cavity formed by the receiving organ has a cross-section that varies along the longitudinal axis, preferably monotonically.

[0014] In one embodiment, the receiving element comprises an airtight material.

[0015] In one embodiment, the receiving organ comprises a silicone-based material.

[0016] In one embodiment, the adapter includes reinforcing elements respectively housed in the lateral openings of the receiving member.

[0017] Reinforcing elements can be components such as metal inserts.

[0018] In one embodiment, the adapter body forms an axial stop.

[0019] In one embodiment, the adapter includes a positioning ring disposed axially between the receiving member and the axial stop of the adapter body, preferably so as to prevent translation of the receiving member relative to the body in one direction along said longitudinal axis.

[0020] In one embodiment, the positioning ring includes an opening having a continuity of form with respect to the cavity of the receiving organ.

[0021] According to a second aspect of the invention, the adapter may include a clamping element for the receiving element.

[0022] In one embodiment, the clamping member includes a movable piston, preferably in translation along the longitudinal axis, between a loosening position and a clamping position in which the piston exerts a clamping force on the receiving member against the body of the adapter.

[0023] In one embodiment, the clamping member includes a cam mounted for rotation relative to the adapter body (3), in particular mounted movably between a first and a second rotational position relative to the body, such that a movement of the cam between the first and second position causes a movement of the piston between the loosening position and the clamping position.

[0024] In one embodiment, the clamping element includes a crank configured to allow an operator to move the cam, in particular between the first and second positions.

[0025] According to a third aspect of the invention, the adapter may include a fluidic connection ring housed in the body of the adapter.

[0026] In one embodiment, the fluidic connection ring is configured to form a radially connected chamber between the fluidic connection ring and the adapter body.

[0027] In one embodiment, the fluidic connection ring includes radial orifices for establishing fluidic communication between said chamber and lateral orifices formed by an intermediate part of the probe.

[0028] According to a fourth aspect of the invention, the adapter may include one or more spacers and sealing elements which are each axially interposed between two respective components of the adapter.

[0029] These components can be chosen from a list including said spacers.

[0030] The said list may also include the aforementioned fluidic connection ring.

[0031] According to a fifth aspect of the invention, the adapter may include a retaining member intended to hold the adapter body in a test position relative to the probe.

[0032] In one embodiment, the retaining member is configured to cooperate with the adapter body via a helical link.

[0033] By way of non-limitation, the retaining element may form a nut configured to cooperate with an external thread of the adapter body.

[0034] According to a sixth aspect of the invention, the adapter may include connection elements configured to connect the adapter to external conduits intended to be connected to said test device.

[0035] In one embodiment, said connection elements can be configured to allow the establishment of fluidic communication between each of said central and lateral orifices of the aforementioned receiving organ and one respective of these external conduits.

[0036] The adapter of the invention can implement only one of the aspects described above, or simultaneously several of these aspects, for example but not limited to all of the aspects described above.

[0037] The invention also relates to a system comprising a test device and an adapter as defined above.

[0038] The invention also relates to a method of mounting an adapter as defined above on a probe, in particular a Pitot probe.

[0039] By way of non-limitation, the probe may include an end provided with a central Pitot tube and lateral ports.

[0040] In an embodiment in which the first aspect described above is implemented, the method may include positioning the adapter so that the probe tip is received in the cavity formed by the receiving member of the adapter, so as to establish fluidic communication on the one hand between the central orifice of the receiving member and the central Pitot duct of the probe and, on the other hand, between the lateral orifices of the receiving member and the respective lateral orifices of the probe tip.

[0041] The invention provides a robust, efficient and ingenious adapter that can be used to test different probes.

[0042] Other advantages and features of the invention will become apparent from the detailed, non-limiting description that follows. Brief description of the figures

[0043] The detailed description that follows refers to the attached drawings on which: - Figure 1 is a simplified schematic view of a system according to the invention and a Pitot probe, the system comprising a test device and an adapter, the system being at a distance from the probe; - Figure 2 is a simplified schematic view of the system and probe of Figure 1, in a configuration in which the adapter is mounted on the probe; - Figure 3 is a perspective view of an adapter according to the invention; - Figure 4 is an axial cross-sectional view of the adapter in Figure 3, along a first cross-sectional plane; - Figure 5 is an axial cross-sectional view of the adapter in Figure 3, along a second cutting plane perpendicular to the first cutting plane; - Figure 6 is a perspective view of a component of the adapter in Figure 3, this component forming a receiving element for the probe; - Figure 7 is a perspective view of a spacer of the adapter in Figure 3. Detailed description of implementation methods

[0044] The figures include a reference frame defining orthogonal directions D1, D2 and D3.

[0045] Figures 1 and 2 schematically and simply represent a system 1 according to the invention and part of a probe 100.

[0046] System 1 more specifically includes a test device 2, an adapter 3 and conduits 4 intended to fluidly connect the device 2 and the adapter 3 to each other.

[0047] The D1-D2-D3 reference frame indicates a relative position of adapter 3 in space.

[0048] In this example, probe 100 is a combined Pitot-static probe, here called a "Pitot probe", belonging to an aircraft's anemobarometric system.

[0049] The probe 100 is in the form of a piece of generally cylindrical shape which extends along an axis A100 defining a central conduit 101, of axis A100, which opens at an end 102 of the probe 100.

[0050] The duct 101 thus forms a Pitot tube allowing the dynamic or impact pressure generated by the movement of the aircraft in the atmosphere to be measured, in this case a movement along the A100 axis.

[0051] In this document, duct 101 is also referred to as the "Pitot duct" or "central Pitot duct".

[0052] In this example, the probe 100 includes lateral orifices 103 which also open at the end 102 of the probe 100, radially outside with respect to the central conduit 101.

[0053] The lateral orifices 103 can be four in number and regularly spaced from each other, circumferentially around the axis A100 of the probe 100.

[0054] Such lateral ports 103 can be used to measure dynamic pressure at different angles of attack during aircraft movement.

[0055] The probe 100 also includes lateral orifices 104 opening radially at an intermediate part 105 of the probe 100.

[0056] The lateral openings 104 form static sockets in a way that is known in itself.

[0057] The test device 2 of system 1 in figures 1 and 2 is a device known by the Anglo-Saxon name "Air Data Test System" or "Air Data Test Set", which typically allows the simulation of pressure conditions to which a Pitot probe is subjected, in particular to test its operation.

[0058] Device 2 includes for this purpose a pressure generator (not shown) and corresponding measuring means (not shown).

[0059] In this non-limiting example, the 4 conduits are flexible pipes.

[0060] The conduits 4, also called "external conduits", are configured to fluidly connect the adapter 3 to the test device 2.

[0061] In this example, adapter 3 is configured to receive a probe such as probe 100 according to the configuration illustrated in Figure 2. In this configuration, system 1 allows probe 100 to be subjected to known pressure conditions which are characteristic of flight conditions, according to techniques which are known as such.

[0062] System 1 can therefore be used to detect possible anomalies in probe 100, for example leaks.

[0063] Figures 3 to 5 show an adapter 3 according to the invention.

[0064] Adapter 3 includes a body 10 which extends along a longitudinal axis Al.

[0065] In this example, the Al axis is parallel to the Dl direction.

[0066] With reference to figures 4 and 5, the body 10 includes a bore 11 opening at a first axial end of the body 10 and a bore 12 opening at a second axial end of the body 10.

[0067] Axially between bores 11 and 12, the body 10 includes an annular ring 13 which extends radially inwards so as to form an opening with axis Al whose diameter is less than that of bores 11 and 12.

[0068] The bores 11 and 12 and the opening formed by the crown 13 thus constitute a common opening which passes through the body 10 from one side to the other along the axis Al.

[0069] The crown 13 has an annular surface 14 which forms an axial stop.

[0070] In this example, the ring 13 includes four blind holes (not shown) which open onto the surface 14. These holes are parallel to the axis Al and are regularly spaced from each other, circumferentially around the axis Al.

[0071] With further reference to figures 4 and 5, the body 10 also includes four radial orifices 17 which open into the part of the opening formed by the bore 11, the orifices 17 being regularly spaced from each other circumferentially around the axis Al.

[0072] The body 10 also includes a radial orifice 18, visible in figure 4, which opens into the part of the opening formed by the bore 12.

[0073] With reference to figures 3 to 5, said first axial end of body 10 forms two legs 20 symmetrical to each other with respect to a plane D1-D2 passing through axis Al.

[0074] The legs 20 each include an orifice 21 defining an axis A2, which in this example is parallel to the direction D3.

[0075] With reference to figures 4 and 5, said second axial end of body 10 has an external thread 25.

[0076] In the non-limiting embodiment described herein, the adapter 3 includes a receiving element 30, shown in isolation in Figure 6.

[0077] The receiving organ 30 has a generally cylindrical shape with axis Al defining axial end surfaces 31 and 32 as well as a peripheral surface 33.

[0078] Surfaces 31 and 32 are each orthogonal to the axis Al. The peripheral surface 33 extends circumferentially around the axis Al.

[0079] Without limitation, the receiving element 30 in this example comprises a silicone-based material forming a molded seal.

[0080] In this embodiment, the receiving member 30 includes a cavity 34 which opens onto the end surface 32. The receiving member 30 includes a central orifice 35 which extends along the axis Al, opening on one side onto the end surface 31 and on the other side into the cavity 34.

[0081] In this example, the cavity 34 has an overall frustoconical geometry, presenting a cross-section which varies monotonically along the axis Al, in this case decreasing along the axis Al from the end surface 32 to the entrance of the central orifice 35.

[0082] In this particular example, the receiving organ 30 comprises four recesses 36 and four surface elements 37 which delimit the cavity 34.

[0083] The recesses 36 are spaced circumferentially from each other around the axis Al, each of the surface elements 37 extending circumferentially between two of these respective recesses 36.

[0084] With further reference to Figure 6, the receiving organ 30 includes lateral orifices 38.

[0085] In this example, the orifices 38 extend radially so as to open, on the one hand, onto one of the surface elements 37 of the cavity 34 and, on the other hand, onto the peripheral surface 33.

[0086] In this example, the receiving organ 30 also includes four lugs 39 which extend to the right of the end surface 32.

[0087] With reference to figures 3 and 6, the adapter 3 includes reinforcing elements 40, in this example in the form of metal inserts, which are each housed in one of the respective lateral orifices 38 of the receiving member 30, in order to prevent their deformation during tightening of the member 30 (see further below).

[0088] With reference to figures 4, 5 and 7, the adapter 3 in this embodiment includes a part 42, also called a "positioning ring" or "spacer".

[0089] With reference to figure 7, the ring 42 has a generally cylindrical shape with axis Al and includes axial end surfaces 43 and 44 as well as a peripheral surface 45.

[0090] In this example, surfaces 43 and 44 are orthogonal to the axis Al. Surface 45 extends circumferentially around the axis Al.

[0091] In this embodiment, the ring 42 includes a bore 46 which opens onto the end surface 44. The ring 42 also includes an opening 47. The opening 47 opens axially on one side onto the end surface 43 and, axially on the other side, is delimited by a shoulder of the ring 42 which forms the opening 47.

[0092] In this example, the opening 47 has a cross-section identical in shape to the cross-section of the cavity 34 of the receiving member 30 at its end surface 32, thus ensuring a continuity of shape between the cavity 34 of the member 30 and the opening 47 of the ring 42. In particular, the opening 47 of the ring 42 has four notches 48 which are configured to come opposite the recesses 36 of the receiving member 30 (see figures 6 and 7).

[0093] With reference to figure 7, the ring 42 includes four orifices 49A and four orifices 49B each passing axially through the ring 42, so as to open each onto the end surfaces 43 and 44.

[0094] The orifices 49A and 49B are spaced circumferentially around the axis Al in an alternating manner.

[0095] The orifices 49A are intended to receive the lugs 39 of the receiving member 30 when the adapter 3 is in the assembled configuration of figures 3 to 5 (see further below).

[0096] In the embodiment of figures 4 and 5, the adapter 3 also includes a ring 50 called a fluidic connection ring.

[0097] In this example, ring 50 includes a bore with axis Al passing axially through ring 50 from one side to the other.

[0098] The ring 50 includes a radially external surface which has a recess 51. The recess 51 is configured so that, when the ring 50 is housed in the body 10 in the configuration illustrated in Figures 4 and 5, this recess 51 delimits an annular chamber 52 which extends radially between the ring 50 and the body 10 of the adapter 3.

[0099] The ring 50 also includes radial orifices 53. The orifices 53 open radially inwards onto said bore of the ring 50. The orifices 53 open radially outwards into the chamber 52 delimited by the recess 51.

[0100] With reference to figures 3 to 5, adapter 3 also includes a clamping element 60.

[0101] In this embodiment, the clamping member 60 comprises a piston 61, a cam 62 and a crank 63.

[0102] Piston 61 has an overall cylindrical shape with an Al axis.

[0103] With reference to figure 4, the piston 61 includes a flat 64 which opens onto a first axial end surface of the piston 61.

[0104] The piston 61 also includes an axial orifice 65 centered on the axis Al. The orifice 65 opens onto a second axial end surface of the piston 61.

[0105] The piston 61 also includes a radial orifice 66. The orifice 66 opens on one side into the axial orifice 65 and, on the other side, onto the flat 64.

[0106] The crank 63 is integral with the cam 62, in this example by being screwed into a threaded hole in the cam 62.

[0107] The cam 62 is mounted to rotate around the axis A2, on a shaft 68 housed in the orifices 21 of the legs 20 of the adapter 3.

[0108] With further reference to figures 3 to 5, adapter 3 also includes a retaining element 70.

[0109] In this example, the component 70 forms a nut configured to cooperate with the external thread 25 of the body 10.

[0110] In the embodiment of figures 4 and 5, the adapter 3 also includes three spacers 80, 81 and 82, as well as three sealing rings 85, 86 and 87.

[0111] A non-limiting method of assembling adapter 3 will now be described.

[0112] The steps described below are provided as a non-limiting example, based on a configuration in which the components of adapter 3 are not assembled together.

[0113] The ring 42 is inserted into the bore 11 of the body 10 and placed against the surface 14 formed by the crown 13 of the body 10, in an angular position in which the orifices 49B are respectively arranged opposite said blind holes of the crown 13.

[0114] In this example, stepped pins (not shown) connect the ring 42 and the body 10 to each other. For each of these pins, a first stage is housed in one of the blind holes in the ring 13, and a second stage is housed in one of the openings 49B in the ring 42. Such pins thus ensure that the ring 42 is held in an angular position relative to the body 10.

[0115] The member 30 is also inserted into the bore 11 of the body 10 and positioned against the surface 43 of the ring 42. The member 30 is angularly arranged so that each of the lugs 39 is housed in one of the respective orifices 49A of the ring 42.

[0116] Thus, the organ 30 and the ring 42 are fixed together in rotation around the axis Al and, by means of said stepped pins, are maintained in an angular position relative to the body 10.

[0117] Axially, the ring 42 is thus positioned between the receiving organ 30 and the crown 13 of the body 10.

[0118] In this example, the piston 61 of the clamping member 60 is then inserted into the bore 11 of the body 10 until said second axial end surface of the piston 61 comes into contact with the surface 31 of the member 30.

[0119] The cam 62 carrying the crank 63 is mounted on the shaft 68 inserted into the orifices 21 of the lugs 20 of the adapter 3, according to the configuration illustrated in figures 3 and 4 in which the cam 62 is in a first angular position which corresponds to a loosening position of the piston 61.

[0120] The cam 62 can be rotated about axis A2 from its first angular position to a second rotary position (not shown). This movement can be achieved by manually operating the crank 63. Given the geometry of the cam 62, such a movement of the cam 62 causes the piston 61 to translate along axis A1 towards the ring 13 of the body 10, thus moving the piston 61 from the loosening position to a tightening position.

[0121] In the clamping position, the piston 61 exerts a clamping force on the receiving member 30, which presses this member 30 against the ring 42 and consequently against the axial stop formed by the surface 14 of the ring 13 of the body 10. The clamping thus results in an axial compression of the receiving member 30.

[0122] Axially on the other side of the ring 13, the following components are inserted into the bore 12 of the body 10 and stacked axially against the ring 13, in the order indicated below and according to the configuration illustrated in Figures 4 and 5: the spacer 80, the sealing ring 85, the ring 50, sealing ring 86, spacer 81, sealing ring 87 and spacer 82.

[0123] The nut 70 can then be screwed onto the thread 25 of the body 10 so as to press these components against the ring 13 of the body 10. In this example, this pressing results from an axial force exerted by the nut 70 on a shoulder 90 of the spacer 82 (see figures 4 and 5).

[0124] With reference to figures 3 and 4, the nut 70 can in this example be held fixed in such a position, relative to the body 10. A screw 91 is fixed to the nut 70 and acts as a handle for the nut 70, in order to provide a grip for tightening said nut 70. Thus, the nut 70, by means of the screw 91, allows the nut 70 to rotate along the thread 25 of the body 10.

[0125] With reference to figures 4 and 5, when the adapter 3 is thus assembled, it forms a probe receiving opening which extends along the axis Al. This probe receiving opening has an axial end delimited by the cavity 34 of the member 30 and comprises a succession of axial sections which are respectively delimited, radially outwards, by the ring 42, the crown 13 of the body 10, the spacers 50, 80, 81 and 82 as well as the sealing rings 85, 86 and 87.

[0126] In this embodiment, when the adapter 3 is assembled as described above, the central orifice 35 of the member 30 is in fluidic communication with the axial orifice 65 of the piston 61 and consequently with the radial orifice 66 of the piston 61 (see Figures 4 and 6). The lateral orifices 38 of the member 30 are in fluidic communication respectively with the orifices 17 of the body 10 (see Figures 4 to 6). The radial orifices 53 of the ring 50 are in fluidic communication with the chamber 52, which extends radially between the ring 50 and the bore 12 of the body 10, and consequently with the orifice 18 of the body 10 (see Figure 4).

[0127] With reference to Figures 3 to 5, the adapter 3 in this example comprises connecting elements 95, 96, and 97 which are fixed to the body 10. Connecting element 95 is connected to the port 66 of the piston 61. Four connecting elements 96 are connected respectively to the orifices 17 of body 10. The connecting element 97 is connected to the orifice 18 of body 10.

[0128] To test a probe such as probe 100 illustrated in Figures 1 and 2, the adapter of the invention, in this non-limiting example the adapter 3 described above with reference to Figures 3 to 7, can be connected to the test device 2 by connecting the conduits 4 to the connection elements 95, 96 and 97 of the adapter 3.

[0129] Adapter 3 can be mounted on probe 100 as illustrated in Figure 2, so that the axis A100 of probe 100 coincides with the axis Al of adapter 3.

[0130] To do this, the adapter 3 can be moved along the axis A100 so that the probe 100 enters said probe receiving opening formed by the adapter 3, in particular so that the end 102 of the probe 100 is received in the cavity 34 of the receiving member 30 of the adapter 3.

[0131] In this particular example, which is by no means limiting, the notches 48 formed by the part 42 (see Figure 7) and the recesses 36 formed by the receiving member 30 (see Figure 6) can be configured to receive ribs (not shown) formed at the end 102 of the probe 100, thus improving the guidance and angular positioning of the adapter 3 when mounted on the probe 100. Furthermore, the arrangement of such ribs of the probe 100 in the recesses 36 of the receiving member 30 improves the test conditions of the probe 100, in particular by preventing or reducing air circulation between the surface elements 37 of the receiving member 30.

[0132] In this example, adapter 3 and probe 100 are arranged relative to each other, establishing fluidic communication: - between the central conduit 101 of the probe 100 and the connecting element 95, via the central orifice 35 of the receiving member 30 and the orifices 65 and 66 of the piston 61; - between each of the lateral ports 103 of the probe 100 and one of the respective connecting elements 96, via the lateral ports 38 of the receiving organ 30 and the corresponding orifices 17 of the body 10; - between the lateral ports 104 of the probe 100 and the connecting element 97, via the radial ports 53 of the ring 50, the chamber 52 and the port 18 of the body 10.

[0133] The component 70 allows the adapter 3 to be maintained on the probe 100 in such a so-called test position.

[0134] Of course, the invention is not limited to the examples just described. In particular, the adapter of the invention may incorporate one or more of the functionalities described above with reference to Figures 3 to 7 and not implement the other functionalities, or implement them differently. Without limitation, the aforementioned functionalities may relate to receiving the probe tip, fluidic connection of the static ports, tightening one or more components of the adapter, locking the adapter onto the probe, etc.

[0135] Furthermore, the components described above may have geometries and / or materials different from those given as examples. For instance, the receiving element 30 may be made of a material lacking silicone.
