Description

Technical Field

[0001] The present application relates to the technical field of aerospace test devices, and particularly relates to a gas rudder force measurement test installation bracket and an operation method thereof. Background Technique

[0002] With the continuous improvement of air combat requirements and the continuous development of aircraft technology, thrust vector control has become an important technology adopted in the vertical launch of aircraft. The gas rudder is a key component of the aircraft thrust vector control technology. Generally, it is arranged at the engine tail nozzle. Under the action of the engine jet flow, the force and moment required to control the rapid turning of the aircraft are generated. Since the flow field of the engine tail nozzle is very complex, and the working space of the gas rudder is small, resulting in serious interference between rudders, it is difficult to obtain the theoretical solution of the aerodynamic characteristics of the gas rudder. Conducting a gas rudder mounted engine ignition force measurement test provides a good method for obtaining the aerodynamic characteristics of the gas rudder. During the preparation process of this test, quickly and accurately adjusting the position between the gas rudder and the engine tail nozzle is a key step in obtaining accurate test data. And this step is achieved through the force measurement test installation bracket.

[0003] The gas rudder force measurement test installation bracket mainly has two methods: the independent installation bracket and the flange installation bracket. Among them, the independent installation bracket is fixed on the test bench, and the flange installation bracket is connected to the engine end flange. The independent installation bracket in the related technology has poor versatility and is difficult to adjust the radial position of the gas rudder relative to the engine; in order to meet the requirements of strength and stiffness, the weight of the installation bracket is generally large. Even when using the cooperation of multiple on-site personnel and a crane to adjust its position relative to the engine, the test preparation time is still long and the efficiency is low, and the position accuracy cannot be fully guaranteed. The independent installation bracket in the related technology is generally composed of multiple plate parts welded into a whole structure, which greatly limits the versatility and adjustability of the bracket.

[0004] Therefore, aiming at the new gas rudder force measurement test requirements, an independent installation bracket for the gas rudder mounted engine ignition force measurement test is developed, which can improve the test efficiency and installation accuracy while meeting the repeated use of multiple models of tests, and provide accurate and reliable aerodynamic test data for gas rudder force measurement.

[0067] To make the objectives, technical solutions, and advantages of the present application more clear and understandable, the following further details the present application in combination with specific embodiments and with reference to the accompanying drawings.

[0068] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of this application should have the ordinary meanings understood by those with ordinary skills in the field to which this application belongs.

The terms such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to represent relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0069] Please refer to Figure 1 , Figure 2 As shown in, this application provides a mounting bracket for a gas rudder force measurement test, including: a frame body 1, which is fixed to the top of a test bench 6 by bolts; a mounting plate 2, on one side of which there are a keyway 201 and bolt holes 202 for mounting a gas rudder force measurement device 5. The keyway 201 is symmetrically arranged along the central hole 203 of the mounting plate 2, and the bolt holes 202 are symmetrically arranged on both sides of the keyway 201; a vertical adjustment device 3, which is installed on the frame body 1 and is used to adjust the position of the mounting plate 2 in the vertical direction; a horizontal adjustment device 4, which is installed on the frame body 1 and is used to adjust the position of the mounting plate 2 in the horizontal direction. Through the gas rudder force measurement test bracket of this application, the frame body 1 and the mounting plate 2 are independently separated compared with the related art, rather than directly fixing the mounting plate 2 on the frame body 1. For different gas rudder force measurement tests, it is more convenient when the mounting plate 2 is damaged or needs to be replaced. Just directly install the mounting plate 2 with the same model size on the frame body. At the same time, for different gas rudder force measurement tests, in the related art, the frame body 1 and the mounting plate 2 are welded into a whole. When it is necessary to adjust the radial position of the gas rudder force measurement device relative to the engine 8, it is necessary to move and adjust the whole frame body 1 and the mounting plate 2, which is difficult. Further, after the frame body 1 and the mounting plate 2 are welded into a whole, when adjusting the position, relative to the radial position of the engine 8, it can still move in the left and right directions, but because it has been welded into a whole in the up and down directions, it is more difficult to meet the movement in the up and down directions. Therefore, its versatility is poor and it is difficult to meet the requirements of the gas rudder force measurement test. However, in this application, the mounting plate 2 can be independently installed on the frame body 1, and then the gas rudder force measurement device 5 is installed on the mounting plate 2. At the same time, the position of the mounting plate 2 is adjusted through the horizontal adjustment device 4 and the vertical adjustment device 3, so that the gas rudder force measurement device 5 moves to a suitable position, and then the gas rudder force measurement test is completed.

[0070] Generally, the gas rudder force measuring device 5 is fixed to the bolt holes 202 on the mounting plate 2 by bolts. The gas rudder force measuring device 5 generally has a boss, which is fittingly embedded into the keyway 201, thus completing the fixation of the gas rudder force measuring device 5. In actual operation, there are generally 4 keyways 201, and the overall contour formed is a "cross shape" or an "X shape". It should be noted that the gas rudder force measuring device 5 generally includes two parts: a force measuring device and a heat protection device.

[0071] Specifically, the main function of the frame 1 is to provide support and fixation, providing stable support and fixation for the installation of the gas rudder force measuring device 5 on the mounting plate 2 later. Therefore, the material requirements for the frame 1 are materials with high rigidity and hardness, and materials that can meet the welding requirements are all acceptable. The horizontal adjustment device 4 and the vertical adjustment device 3 need to be fixed on the frame 1, and at the same time, it is necessary to ensure that the vertical adjustment device 4 and the vertical adjustment device 3 can adjust the vertical position and horizontal position of the mounting plate 2.

[0072] Furthermore, in some embodiments, as Figure 5 、 Figure 6 shown, the frame 1 includes: a cross beam 101, a first side vertical plate 102, a second side vertical plate 103, a lower vertical plate 104, and a base plate 105. By arranging the first side vertical plate 102 and the second side vertical plate 103 opposite to each other, welding the cross beam 101 at their tops, welding the lower vertical plate 104 at their bottoms, and welding the base plate 105 on the lower surface of the lower vertical plate 104, the frame 1 is a frame structure. The cross beam 101 includes opposite first vertical surfaces 1011 and second vertical surfaces 1012. There are a first through hole 1013 and a first through slot 1014 on the cross beam 101 for installing the vertical adjustment device 3. There are a second through hole 1021 and a second through slot 1022 on the first side vertical plate 102 for installing the horizontal adjustment device 4. In order to install the vertical adjustment device 3 and the horizontal adjustment device 4, bolts are respectively passed through the first through hole 1013 to fix the vertical adjustment device 3, and bolts are passed through the second through hole 1021 to fix the horizontal adjustment device 4. Generally speaking, the vertical adjustment device 3 and the horizontal adjustment device 4 also have matching through holes to facilitate bolt fixation. Among them, the vertical adjustment device 3 is arranged in the first through slot 1014, and the horizontal adjustment device 4 is arranged in the second through slot 1022.

[0073] U-shaped grooves 1051 are symmetrically arranged on both sides of the base plate 105, and the base can be fixed to the test bench through T-slot bolts, thereby further fixing the frame 1 to the test bench.

[0074] Furthermore, in some embodiments, as Figure 7 、 Figure 8As shown in the figure, the vertical adjustment device 3 includes: a first bottom plate 31, a first middle slide plate 32, a first upper slide plate 33, a first bearing fixing seat 34, a first lead screw 35, and a first handwheel 36;

[0075] The first bottom plate 31 is fixedly connected in the first through groove 1014 of the cross beam 101. A first strip-shaped groove 311 is provided in the middle of the first bottom plate 31. Through the first through hole 1013 on the second vertical surface 1012 of the cross beam 101, relatively speaking, corresponding through holes 137 are also provided on the first bottom plate 31, so that the first bottom plate 31 is directly fixed on the cross beam 101. The first middle slide plate 32 is slidably connected to the first bottom plate 31 through a first vertical dovetail groove 37, so that the first middle slide plate 32 can move up and down along the first vertical dovetail groove 37. The first upper slide plate 33 is slidably connected to the first middle slide plate 32 through a first horizontal dovetail groove 38, so that the first upper slide plate 33 can move left and right along the first horizontal dovetail groove 38.

[0076] A first nut 321 is provided on one side of the first middle slide plate 32 close to the first bottom plate 31. A first bearing fixing seat 34 is provided at the top of the first bottom plate 31. A first tapered roller bearing 341 is installed face to face inside the first bearing fixing seat 34. The first lead screw 35 vertically penetrates the first bearing fixing seat 34 and the top of the first bottom plate 31. The first nut 321 is engaged with the first lead screw 35. The first lead screw 35 is fixedly connected to the inner ring of the first tapered roller bearing 341. The outer ring of the first tapered roller bearing 341 is fixed to the first bearing fixing seat 34. Here, by rotating the first lead screw 35, the first nut 321 can be driven to move along the first lead screw 35 on the first lead screw 35, thereby driving the first middle slide plate 32 to move. The first vertical dovetail groove 37 can not only limit the first middle slide plate 32 and the first bottom plate 31, but also enable the first middle slide plate 32 to slide. It should be noted that the number of the first nuts 321 can be configured as needed. As an alternative solution, the present application provides a first nut 321 at each of the upper and lower ends on the back of the first middle slide plate 32. In addition, in order to cooperate with the first lead screw 35 to rotate in the first bearing fixing seat 34, two first tapered roller bearings 341 are arranged face to face inside the first bearing fixing seat 34. Due to the characteristics of the tapered roller bearing and the force analysis, it can effectively bear the weight of the subsequent mounting plate 2 and the weight of the gas rudder force measuring device 5. Here, the first nut 321 is coaxial with the first tapered roller bearing 341 to ensure that the first middle slide plate 32 moves smoothly in the vertical direction.

[0077] The first handwheel 36 is fixedly connected to one end of the first lead screw 35 close to the first bearing fixing seat 34. Here, the first handwheel 36 is fixed to the first lead screw 35 by a flat key. Here, in order to make the connection between the first lead screw 35 and the first tapered roller bearing 341 closer, a first gasket 3411, a first round nut 3412 and a second gasket 3413 are respectively arranged on the first lead screw 35 in the middle section between the first handwheel 36 and the first tapered roller bearing 341. The first gasket 3411 is installed on the inner ring of the first tapered roller bearing 341. The first round nut 3412 is connected to the first lead screw 35 by a thread. At the same time, the first round nut 3412 is fixed on the upper surface of the first gasket 3411. And the first handwheel 36 further presses the handwheel on the second gasket 3413 through an M16 nut. The lower surface of the second gasket 3413 is fixed to the upper surface of the first round nut 3412.

[0078] Further, in some embodiments, as Figure 9 , Figure 10 shown, the horizontal adjustment device 4 includes: a second bottom plate 41, a second middle slide plate 42, a second upper slide plate 43, a second bearing fixing seat 44, a second lead screw 45 and a second handwheel 46. Compared with the vertical adjustment device 3 above, the horizontal adjustment device 4 has the same principle as the vertical adjustment device 3. However, it should be noted that here, the second bottom plate 41 has the same thickness as the first bottom plate 31, the second middle slide plate 42 has the same thickness as the first middle slide plate 32, the second upper slide plate 43 has the same thickness as the first upper slide plate 33, and even their size specifications can be the same. The second bottom plate 41 is also installed on the second rear vertical plate 1032 through the second through hole 1021. The second bearing fixing seat 44 is installed on the left side of the second middle slide plate 42. The second strip-shaped groove 421 is arranged on the second middle slide plate 42. Through the second vertical dovetail groove 47, the second middle slide plate 42 moves up and down. The second horizontal dovetail groove 48 makes the second upper slide plate 43 move left and right. Correspondingly, a second tapered roller bearing (not shown in the figure) arranged face to face is also provided in the second bearing fixing seat 44. The installation principle of the second handwheel 46 is the same as that of the first handwheel 36 and will not be elaborated here.

[0079] Compared with the vertical adjustment device 3, a second strip-shaped groove 421 is provided on the second middle slide plate 42 of the horizontal adjustment device 4. At the same time, a second nut 431 is provided on one side of the second upper slide plate 43 close to the second middle slide plate 42. The second nut 431 is also coaxial with the second tapered roller bearing on the left side of the second middle slide plate 42. The second nut 431 moves horizontally in the second strip-shaped groove 421 by relying on the rotation of the second lead screw 45, thereby driving the second upper slide plate 43 to move horizontally along the second horizontal dovetail groove 48 in the horizontal direction.

[0080] It should be noted here that in order to increase the load-bearing capacity of the first lead screw 35 and the second lead screw 45, both the first lead screw 35 and the second lead screw 45 are trapezoidal lead screws.

[0081] In some embodiments, as Figure 10 shown, at one end of the second strip-shaped groove 421 away from the second bearing fixing seat 44, there is a bearing base 49. The bearing base 49 is fixed in the second strip-shaped groove 421. An angular contact bearing 491 is provided in the bearing base 49. One end of the second lead screw 45 away from the bearing fixing seat is fixed to the inner ring of the angular contact bearing 491; a retaining ring 492 is provided in the bearing base 49, and the retaining ring 492 is fixedly connected to the outer ring of the angular contact bearing 491. Here, the angular contact bearing 491 is coaxial with the second tapered roller bearing. In order to keep the second lead screw 45 horizontal and prevent its position from shifting when the second lead screw 45 is subject to gravity, a retaining ring 492 is provided on the outer ring of the angular contact bearing 491 so that it will not come out of the bearing base 49 when it is subject to a large single-direction axial load.

[0082] Furthermore, in some embodiments, as Figure 5 shown, the first side vertical plate 102 further includes a first front vertical plate 1023 and a first rear vertical plate 1024, and the second side vertical plate 103 further includes a second front vertical plate 1031 and a second rear vertical plate 1032. The first vertical surface 1011 of the cross beam 101, the first front vertical plate 1023, the second front vertical plate 1031, and the lower vertical plate 104 are in the same plane. Here, it provides a fixing plane for the subsequent fixing installation plate 2. If they are not in the same plane, then when the installation plate 2 is fixed through the first elongated hole 1025 and the second elongated hole 204 later, the installation plate 2 cannot be completely attached to the surfaces of the first vertical surface 1011, the first front vertical plate 1023, the second front vertical plate 1031, and the lower vertical plate 104, and there will be gaps, making it impossible to complete the overall fixing of the installation plate 2.

[0083] The second vertical surface 1012 of the cross beam 101 is in the same plane as the first rear vertical plate 1024 and the second rear vertical plate 1032. The first bottom plate 31 of the vertical adjustment device 3 needs to be fixed on the second vertical surface 1012. The second bottom plate 41 of the horizontal adjustment device 4 needs to be fixed on the first rear vertical plate 1024. The third bottom plate 71 of the cross adjustment device 7 needs to be fixed on the second rear vertical plate 1032 after fixation. During the process of adjusting the mounting plate 2, the mounting plate 2 needs to be fixed on the mounting surfaces of the first upper slide plate 33, the second upper slide plate 43 and the third upper slide plate 73 first; the first rear vertical plate 1024, the second rear vertical plate 1032 and the second vertical surface 1012 of the cross beam 101 are in the same plane; the vertical adjustment device, the horizontal adjustment device and the cross adjustment device mounted on the frame 1, the thickness selection of the first bottom plate 31, the second bottom plate 41 and the third bottom plate 71 can be of the same specification, and the thickness selection of the first middle slide plate 32, the second middle slide plate 42 and the third middle slide plate 72 can also be of the same specification. Correspondingly, the thickness selection of the first upper slide plate 33, the second upper slide plate 43 and the third upper slide plate 73 can also be of the same specification. During the production process, there is no need to make different settings for the thickness alone, and there is no need to design the thickness specification parameters separately, saving production time.

[0084] Further, in some embodiments, such as Figure 4 , Figure 11 shown, it further includes a cross adjustment device 7, including a third bottom plate 71, a third middle slide plate 72 and a third upper slide plate 73. Through the above description, the third bottom plate 71 has the same thickness as the first bottom plate 31 and the second bottom plate 41, the third middle slide plate 72 has the same thickness as the first middle slide plate 32 and the second middle slide plate 42, and the third upper slide plate 73 has the same thickness as the first upper slide plate 33 and the second upper slide plate 43. The cross adjustment device 7 mainly plays a supporting role. The horizontal adjustment device 4 is installed on the first side vertical plate 102. In order to ensure that when the mounting plate 2 is installed, and even when the gas rudder force measuring device 5 is installed subsequently, the force is balanced and the horizontal adjustment device 4 will not be damaged, the cross adjustment device 7 is installed. In addition, the third vertical dovetail groove 75 can assist vertical movement, and the third horizontal dovetail groove 74 can assist horizontal movement. It should be noted that for the convenience of description, the horizontal adjustment device 4 is installed on the first side vertical plate 102, while the cross adjustment device is installed on the second side vertical plate. It is also feasible to interchange the positions of the horizontal adjustment device 4 and the cross adjustment device 7.

[0085] So far, the mounting plate 2 is mounted on the mounting surfaces of the first upper slide plate 33, the second upper slide plate 43 and the third upper slide plate 73. By rotating the first handwheel 36, the first middle slide plate 32 moves up and down along the rotation of the first lead screw 35, and the second middle slide plate 42 and the third middle slide plate 72 also move up and down. After adjusting the vertical position, rotate the second handwheel 46, and the second upper slide plate 43 moves horizontally along the rotation of the second lead screw 45. The first upper slide plate 33 and the third upper slide plate 73 also move horizontally to adjust the horizontal position of the mounting plate 2. It should be noted here that when adjusting the horizontal position and the vertical position of the mounting plate 2, there is no order priority, and the adjustment can also be carried out simultaneously.

[0086] Further, in some embodiments, as Figure 5 , Figure 6 shown, the first vertical surface 1011, the first front vertical plate 1023, the second front vertical plate 1031, and the lower vertical plate 104 of the cross beam 101 are all provided with first strip-shaped holes 1025. The mounting plate 2 is provided with second strip-shaped holes 204 corresponding to the first strip-shaped holes 1025. After the mounting plate 2 is adjusted to the proper position, in order to prevent the mounting plate 2 from moving again, the mounting plate 2 and the frame body 1 are fixed by bolts in the first strip-shaped holes 1025 and the corresponding second strip-shaped holes 204, preparing for fixing the gas rudder force measuring device 5 and the test later.

[0087] In some embodiments, as Figure 3 shown, the mounting plate 2 is provided with counterbores 205. The mounting plate 2 is fixedly connected to the first upper slide plate 33, the second upper slide plate 43 and the third upper slide plate 73 respectively by bolts through the counterbores 205. Of course, it should be noted that the first upper slide plate 33, the second upper slide plate 43 and the third upper slide plate 73 also have corresponding bolt holes. After the bolts are inserted into the counterbores 205, the mounting plate 2 is fixed on the first upper slide plate 33, the second upper slide plate 43 and the third upper slide plate 73 through the cooperation with the bolt holes.

[0088] As Figure 5 shown, it further includes triangular reinforcing plates 106. The triangular reinforcing plates 106 are welded between the first rear vertical plate 1024 and the bottom plate and between the second rear vertical plate 1032 and the bottom plate, maintaining the stability of the frame body 1 and providing a stress point for the frame body 1 when conducting tests later.

[0089] Through Figure 3 , Figure 5It can be seen that after adjusting the position of the mounting plate 2 relative to the frame body through the vertical adjusting device 3 and the horizontal adjusting device 4, it is necessary to fix the mounting plate 2. The fixing bolts are used to pass through the first elongated hole 1025 and the corresponding second elongated hole 204 for fixing. Here, the first elongated hole 1025 and the corresponding second elongated hole 204 are vertically arranged. For example, if the first elongated hole 1025 extends in the up-and-down direction in the spatial direction, then the corresponding second elongated hole 204 extends in the horizontal direction in the spatial direction. By doing so, the adjustment range of the position of the mounting plate 2 is increased, and at the same time, it can be carried out for different gas rudder force measurement tests. At the same time, different specifications of mounting plates 2 need to be used, and there is greater versatility when adjusting the position.

[0090] It should be noted that there are mounting round holes on the second vertical surface 1012 of the cross beam 101 corresponding to the first elongated hole 1025, the first rear vertical plate 1024 corresponding to the first front vertical plate 1023, and the second rear vertical plate 1032 corresponding to the second front vertical plate 1031. Here, it is for the convenience of operation when fixing the first elongated hole 1025 and the second elongated hole 204.

[0091] As Figure 12 shown, the present application also proposes an operation method for a gas rudder force measurement test mounting bracket, including:

[0092] S101. Fix the vertical adjusting device 3 and the horizontal adjusting device 4 to the frame body 1 through bolts respectively;

[0093] Specifically, here, the first bottom plate 31 of the vertical adjusting device 3 is fastened to the second vertical surface 1012 of the cross beam 101 through bolts, the second bottom plate 41 of the horizontal adjusting device 4 is fastened to the first rear vertical plate 1024 through bolts, and at the same time, the third bottom plate 71 of the cross adjusting device 7 can also be fastened to the second rear vertical plate 1032 through bolts to achieve the purpose of fixing the vertical adjusting device 3, the horizontal adjusting device 4, and the cross adjusting device 7 to the frame body respectively.

[0094] S102. Fix the mounting plate 2 to the vertical adjusting device 3, the horizontal adjusting device 4, and the cross adjusting device 7 through bolts respectively;

[0095] The mounting plate 2 is fixed to the bolt holes corresponding to the counterbores 205 on the first upper sliding plate 33, the second upper sliding plate 43, and the third upper sliding plate 73 through bolts inserted into the counterbores 205 on it.

[0096] S103. Fine-tune the vertical position of the mounting plate 2 through the vertical adjusting device 3, and fine-tune the horizontal position of the mounting plate 2 through the horizontal adjusting device 4 until the central hole 203 of the mounting plate 2 is coaxial with the engine 8;

[0097] Among them, by rotating the first handwheel 36, the first nut 321 of the first middle slide plate 32 moves up and down along the first lead screw 35 in the first strip-shaped groove 311 to adjust the vertical position of the mounting plate 2. Then, rotate the second handwheel 46, and the second nut 431 of the second upper slide plate 43 moves horizontally along the second lead screw 45 in the second strip-shaped groove to adjust the horizontal position of the mounting plate 2 until the central hole 203 of the mounting plate 2 is coaxial with the engine 8.

[0098] It should be noted that it is possible to rotate the first handwheel 36 or the second handwheel 46 first, or rotate both of them simultaneously for adjustment. For the convenience of description here, this is not a limitation on the sequence.

[0099] S104. Fix the mounting plate 2 on the frame body 1 by using hexagon socket head cap screws. Pass the hexagon socket head cap screws through the first strip-shaped hole 1025 and the corresponding second strip-shaped hole 204 to fix the mounting plate 2 on the frame body 1, so as to prevent the first handwheel 36 and the second handwheel 46 from being accidentally rotated to move the position of the mounting plate 2 again, and at the same time prevent the mounting plate 2 from shifting in position due to the force during the test.

[0100] S105. Install the gas rudder force measuring device 5 on the mounting plate 2 by using the bolt holes 202 and the keyway 201.
