During the test running, the linkage of the engine and the fuel, hydraulic, electrical and other systems is checked to ensure that each component works normally, so as to verify the system cooperation, and the thrust, speed, oil pressure and other parameters of the engine are tested under simulated flight conditions to verify whether the performance meets the design standard. During this process, the high-temperature and high-speed exhaust gas discharged by the aircraft engine under high-thrust test running threatens the safety of ground personnel and vehicles. Therefore, the high-temperature and high-speed exhaust gas needs to be guided.

[0004] The above document uses the function of the guide wall to guide the exhaust gas into the inside of the blade group and drive the blade group to rotate, so that the rotating shaft rotates, and under the action of the transmission mechanism, the generator works to complete power generation, thereby increasing the utilization rate of high-temperature and high-speed exhaust gas. However, the entire structure of the guide wall is fixed on the support truss, and the guide wall is transported to the test site by a transport vehicle before use, and also needs to be transported away from the test site after use.

[0012] Further, the turning device comprises a first drive, a first connecting rod and a second connecting rod, both ends of the first connecting rod are respectively connected with the first frame and the first drive output end fixed on the first frame, both ends of the second connecting rod are respectively connected with the second frame and the first drive output end;

[0013] Step S3 also includes:

[0014] Through the first drive output end to execute the action and drive the first connecting rod around the first frame downward, while driving the second connecting rod downward, then make the second connecting rod to the first connecting rod of the second frame generates a push force and acts on the second frame, and then make the second frame around the first frame and the hinge of the second frame upward, so as to turn over the second frame to the first deflector above.

[0015] The above setting, when not in use, can be driven by the first drive to make the first connecting rod rotate downward around the first frame, while making the second connecting rod generate a push force to the second frame, acting on the second frame and making the second frame rotate upward around the hinge of the first frame and the second frame, so as to turn over the second frame to the first frame above; while in use, the first drive is reversed to drive the first connecting rod and the second connecting rod to rotate, so as to turn over the second frame downward around the first frame to realize the reset.

[0018] Further, the second frame body is provided with a first connecting rod, the first connecting rod is arranged between the two second limiting rods, the first connecting rod is provided with a first connecting ear, and the first connecting rod is hingedly connected to the second limiting rods in the second limiting through slot after penetrating through the two second limiting rods through a first rotating shaft.

[0019] The above arrangement facilitates the rotation connection of the first driving member to the first connecting ear of the first connecting rod through the second connecting rod, limits the first connecting rod by the two second limiting rods, and avoids the deviation swing of the first connecting rod during the rotation.

[0020] Further, the first connecting rod is provided with two ends, one end of the two first connecting rods rotatably connected to the output end of the first driving member is arranged on the two sides of one end of the second connecting rod rotatably connected to the output end of the first driving member, the other end of the first connecting rod is rotatably connected to the second connecting ear through a second rotating shaft, and the other end of the second connecting rod is rotatably connected to the first connecting ear through a third rotating shaft.

[0021] The above arrangement facilitates the rotation of the first connecting rod of the first frame body through the joint action of the first connecting rod and the second connecting rod.

[0022] Further, the first frame body is provided with a first flow guide plate, the second frame body is provided with a second flow guide plate, the support devices on each flow guide wall are provided with two and are arranged on the side of the first frame body away from the first flow guide plate, the support devices include a second driving member, a support frame, and a fixed shaft, the second driving member is hingedly connected to the first frame body, the fixed shaft is rotatably connected to a third connecting ear arranged on the first frame body after penetrating through one side of the support frame, and one side of the support frame is rotatably connected to the output end of the second driving member.

[0023] The step S1 further includes:

[0024] The second driving member performs the extension action to push the support frame to rotate 90° around the first frame body and be perpendicular to the reference line;

[0025] The step S3 further includes:

[0026] The second driving member performs the retraction action to pull the support frame to reversely rotate 90° around the first frame body and be attached to the side of the first frame body away from the first guide plate.

[0027] The above arrangement can support the entire guide wall through the support device during the gas guiding process of the guide wall, preventing the guide wall from deviating from the position.

[0028] Further, the locking assembly includes a first locking plate, a locking member, and a second locking plate, and the first locking plate and the second locking plate are both provided with through holes matched with the locking member;

[0029] The step S2 further includes:

[0030] After the adjacent guide walls are spliced along the reference line, the first locking plate and the second locking plate are respectively placed on the adjacent two guide walls, and the through holes of the first locking plate and the second locking plate are aligned with the through holes of the fourth connecting lug arranged at the splicing position of the adjacent two guide walls, and then the locking member is sequentially inserted through the first locking plate, the fourth connecting lug, and the second locking plate to be fixed.

[0031] The above arrangement can improve the connection stability between the adjacent guide walls spliced along the reference line.

[0032] Further, the connecting assembly includes an arc-shaped connecting plate and a connecting member, and the arc-shaped connecting plate is provided with two or more screw holes matched with the connecting member;

[0033] The step S3 further includes:

[0034] After the second frame body is flipped to the top of the first frame body, the upper end of the flipped second frame body forms an arc-shaped mounting surface with the upper end of the first frame body, the screw holes of the arc-shaped connecting plate are aligned with the screw holes of the upper connecting block of the first frame body and the screw holes of the upper connecting block of the second frame body, and then the connecting member is sequentially inserted through the arc-shaped connecting plate and the connecting block and is threadedly connected with the screw holes to be fixed.

[0035] The above arrangement can connect the first frame body and the second frame body on the two symmetrically arranged guide walls to form an integral whole, thereby making the overall stability better.

[0036] Further, in the step S2, the second frame body is flipped downward around the first frame body to the side of the first frame body by the flipping device, so that the second frame body and the side of the second frame body are attached to each other to form an arc-shaped mounting surface.

[0037] The above setup involves flipping the second frame to one side of the first frame before testing, thus creating an arc-shaped mounting surface between the first and second frames, which allows for the installation of the first and second air deflectors.

[0038] Furthermore, step S4 also includes:

[0039] Release the locking mechanism from fixing the first and second locking plates, and then remove the first and second locking plates.

[0040] Step S5 also includes:

[0041] The first locking plate and the second locking plate are placed between the two first frames of the two guide walls, and the through holes of the first locking plate and the second locking plate are aligned with the through holes of the fourth connecting ear. Then, the locking member is passed through the first locking plate, the fourth connecting ear and the second locking plate in sequence to achieve fixation.

[0042] The above setup involves disassembling the first and second locking plates used for fixing in step S2 before hoisting, and then using the disassembled first and second locking plates to fix the guide walls together. This avoids the need for additional parts for fixing and prevents the loss of parts. At the same time, it makes the connection between the two symmetrically arranged guide walls more stable before hoisting and transportation.

[0043] The beneficial effects of this invention are as follows: After the first frame is placed on the test site, by opening the support device and setting it perpendicular to the baseline, the first frame can be better supported. Simultaneously, using the first placed guide wall as a reference, other guide walls can be aligned and spliced ​​along the baseline. Adjacent guide walls are then fixed together using locking components, forming a single unit, thus improving overall support stability. After gas flow is completed, the second frame is flipped above the first frame using a flipping device, while the support device is closed, thereby reducing the overall space occupied by the guide walls. After an adjacent guide wall is rotated along the baseline, the adjacent guide walls are symmetrically arranged about the baseline. The two symmetrical guide walls are fixed by the locking components after disassembly. This makes the two guide wall structures connected into one unit along the width of the guide wall. The upper ends of the two symmetrical guide walls are also connected into one unit by the connecting components, which makes the overall structure more compact. Because of the symmetrical arrangement, the stress on the whole structure is even during hoisting and transportation, effectively avoiding the problem of uneven stress on the overall structure due to the inability to fold the structure, which would lead to inconvenience and time-consuming hoisting and transportation.

Detailed Implementation

[0060] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0061] like Figures 1-13 As shown, the present invention provides a method for using an aircraft ground test deflector wall. The deflector wall 21 includes a first frame 1, a flipping device, and a second frame 2. The first frame 1 is provided with a first deflector plate 3, and the second frame 2 is provided with a second deflector plate 4. The flipping device is disposed on the first frame 1. The first frame 1 is provided with two second limiting rods 5, forming a second limiting through groove between the second limiting rods 5. The second limiting rods 5 are provided with second connecting ears 6. The second frame 2 is provided with a first connecting rod 7, which is disposed between the two second limiting rods 5. The first connecting rod 7 is provided with a first connecting ear 8. The first connecting rod 7 passes through the two second limiting rods 5 via a first rotating shaft 9 and is hinged to the second limiting rods 5 in the second limiting through groove. This allows the first frame 1 and the second frame 2 to rotate hingedly. During the rotation, the two second limiting rods 5 simultaneously limit the first connecting rod 7 to prevent the first connecting rod 7 from deviating or swinging. In this embodiment, there are two hinges between the first frame 1 and the second frame 2 on each guide wall 21, which makes the second frame 2 more stable during rotation when the flipping device drives the second frame 2 to rotate.

[0062] like Figure 13As shown, the lower end of the first frame 1 is provided with a first frame 101, the cross-section of which is a square frame structure. The upper end of the first frame 101 is provided with a first second frame 102, which includes a first second horizontal frame 1021, a first second vertical frame 1022, and a first second arc-shaped frame 1023. The first second horizontal frame 1021, the first second vertical frame 1022, and the first second arc-shaped frame 1023 are connected end to end to form a frame. The second frame 2 includes a second first horizontal frame. The second vertical frame 202, the second arc-shaped frame 203, the second horizontal frame 201, the second vertical frame 202, and the second arc-shaped frame 203 are connected end to end to form a frame. After the second frame 2 is unfolded, the height of the second vertical frame 202 is set to be equal to the height of the first frame 101. The first and second arc-shaped frames 1023 and the second arc-shaped frame 203 are arranged opposite to each other to form a complete arc-shaped support frame. The first guide plate 3 and the second guide plate 4 are set on the arc-shaped support frame.

[0063] like Figure 6 and 7 As shown, the flipping device includes a first driving member 10, a first connecting rod 11, and a second connecting rod 12. The two ends of the first connecting rod 11 are rotatably connected to the first frame 1 and the output end of the first driving member 10, which is hinged to the first frame 1, respectively. The two ends of the second connecting rod 12 are rotatably connected to the second frame 2 and the output end of the first driving member 10, respectively. Two first limiting rods 13 are also provided on the first frame 1. The first limiting rods 13 and the second limiting rods 13 are inclined and form a first limiting through groove between adjacent first limiting rods 13. The output end of the first driving member 10 passes through the first limiting through groove and is rotatably connected to the first frame 1 through a fourth rotating shaft. This facilitates the first driving member 10 to drive the first connecting rod 11 and the second connecting rod 12 to push the second frame 2 to rotate and flip around the first frame 1. During the flipping process, the first driving member 10 can also rotate around the first frame 1 to avoid jamming. At the same time, the two first limiting rods 13 can limit the two sides of the first driving member 10 to prevent the first driving member 10 from deviating and swinging during rotation. In this embodiment, the first driving component 10 is a cylinder.

[0064] like Figure 6 and 7As shown, there are two first connecting rods 11. One end of the first connecting rod 11 and one end of the second connecting rod 12 are rotatably connected to the output end of the first driving member 10 through the fifth rotating shaft 120. One end of the two first connecting rods 11 rotatably connected to the output end of the first driving member 10 are respectively set on both sides of one end of the second connecting rod 12 rotatably connected to the output end of the first driving member 10. The other end of the first connecting rod 11 is set inside the second connecting ear 6 and is rotatably connected to the second connecting ear 6 through the second rotating shaft 14. At the same time, the distance between the second connecting ears 6 matches the distance of the second limiting through groove. The other end of the second connecting rod 12 is rotatably connected to the first connecting ear 8 through the third rotating shaft. In this embodiment, the width of the second connecting rod 12 is smaller than the distance of the second limiting through groove so that the second connecting rod 12 can pass through the second limiting groove during the rotation of the second frame 2.

[0065] In this embodiment, the length of the first link 11 is greater than the length of the second link 12. Since the first connecting ear 8 is located above the second connecting ear 6, the first link 11 needs to rotate around the first frame 1 by a larger radius during the process of pushing the second frame 2 to rotate to the position above the first frame 1.

[0066] like Figure 12 As shown, each guide wall 21 has two support devices, both located on the side of the first frame 1 away from the first guide plate. Each support device includes a second drive member 22, a support frame, and a fixed shaft 23. The second drive member 22 is hinged to the first frame. The fixed shaft 23 passes through one side of the support frame and is rotatably connected to a third connecting ear 24 located on the first frame. One side of the support frame is rotatably connected to the output end of the second drive member 22. In this embodiment, the support frame includes a first support rod 25, a second support rod 26, a third support rod 27, a fourth support rod 28, and two fifth support rods 29. The fourth support rod 28 has a fifth connecting ear 30, which is connected to the output end of the second drive member 22 via a sixth rotating shaft 301. The fourth support rod 28 is rotatably connected to the fifth support rod 29 at both ends. The fixed shaft 23 passes through the fifth support rod 29 and is rotatably connected to the third connecting ear 24. One end of the first support rod 25 is fixedly connected to a fifth support rod 29. One end of the second support rod 26 is fixedly connected to another fifth support rod 29. The other end of the first support rod 25, which is inclined downward relative to a fifth support rod 29, is fixedly connected to the other end of the second support rod 26, which is inclined downward relative to another fifth support rod 29. The third support rod 27 is fixedly connected between the first support rod 25 and the second support rod 26, so as to stably support the first frame. In this embodiment, the second driving component 22 is a cylinder.

[0067] like Figure 10 and 11As shown, the locking assembly includes a first locking plate 31, a locking element, and a second locking plate 32. Both the first locking plate 31 and the second locking plate 32 have through holes that match the locking element. This locking assembly, through its fixing effect, improves the connection stability between adjacent guide walls 21 spliced ​​along the baseline, and also provides greater stability for the connection between two symmetrically arranged guide walls 21 before hoisting and transportation. In this embodiment, the lengths of the first locking plate 31 and the second locking plate 32 match the spacing between the fourth connecting ears 33 on the first frame, and the locking element consists of a bolt and a nut that matches the bolt.

[0068] like Figure 10 As shown, the connecting assembly includes an arc-shaped connecting plate 34 and a connector 35. The arc-shaped connecting plate 34 has two or more screw holes that match the connector 35. Through the fixing connection of the connecting assembly, the first and second frames on the two symmetrically arranged guide walls 21 can be connected into one unit, thus ensuring overall stability. In this embodiment, the connector 35 is a screw that matches the screw holes.

[0069] The installation method includes the following specific steps:

[0070] S1 marks a preset baseline on the test site along the direction perpendicular to the gas flow. Based on the preset baseline, the side of the first frame 1 away from the first guide plate 3 is aligned with the baseline and placed on the test site. Then, the support device is opened, and the second drive member 22 performs an extension action, pushing the support frame to rotate 90° around the first frame 1 and set it perpendicular to the baseline.

[0071] S2 continues to splice the guide wall 21 along the baseline at one end of the first frame 1, and then fixes it between the guide walls 21 by locking components. Specifically, the first locking plate 31 and the second locking plate 32 are placed on two adjacent guide walls 21 respectively, and the through holes of the first locking plate 31 and the second locking plate 32 are aligned with the through holes of the fourth connecting ear 33 set at the splicing point of the two adjacent guide walls 21. Then, the locking component is passed through the first locking plate 31, the fourth connecting ear 33 and the second locking plate 32 in sequence to achieve fixation until the length of the spliced ​​guide wall 21 meets the length required by the test site.

[0072] After completing the test run, S3 folds up the adjacent guide wall 21. The specific folding process is as follows: the output end of the first drive unit extends and drives the first connecting rod 11 to rotate downward around the first frame 1, while simultaneously driving the second connecting rod 12 to rotate downward. Then, the second connecting rod 12 exerts a pushing force on the first connecting rod 11 of the second frame 2 and acts on the second frame 2, thereby causing the second frame 2 to rotate upward around the hinge between the first frame 1 and the second frame 2, thus flipping the second frame 2 above the first guide plate 3. After the second frame 2 is flipped above the first guide plate 3, the screw holes of the arc-shaped connecting plate 34 are aligned with the screw holes of the connecting block on the first frame 1 and the connecting block on the second frame 2, respectively. Then, the connecting piece 35 passes through the arc-shaped connecting plate 34 and the connecting block in sequence and is threadedly connected to the screw holes to achieve fixation. Then, the second drive unit 22 performs a retraction action, pulling the support frame to rotate 90° in the opposite direction around the first frame 1 and then attaching it to the side of the first frame 1 away from the first guide plate.

[0073] S4 Remove the locking parts used to fix the first locking plate 31 and the second locking plate 32 between the guide walls 21, and remove the first locking plate 31 and the second locking plate 32. Rotate an adjacent guide wall 21 180° along the intersection of the two adjacent guide walls as the rotation axis, so that the two guide walls 21 are symmetrically arranged about the baseline and the two ends of the guide walls 21 are aligned.

[0074] S5 places the first locking plate 31 and the second locking plate 32 between the two first frames 1 of the two guide walls 21 at both ends of the guide wall 21, and aligns the through holes of the first locking plate 31 and the second locking plate 32 with the through holes of the fourth connecting ear 33. Then, the locking member passes through the first locking plate 31, the fourth connecting ear 33 and the second locking plate 32 in sequence to fix the two guide walls 21, so that the two guide walls 21 after folding the first frames are symmetrically arranged and connected to form a whole. The guide wall is lifted onto the transport vehicle and transported away from the test site by hooking the arc-shaped mounting plate position with the hoisting equipment.

[0075] The working principle of this invention is as follows: After the first frame 1 is placed on the test site, the support device is opened and set perpendicular to the baseline to support the first frame 1. Then, using the first placed guide wall 21 as a reference, the other guide walls 21 are aligned and spliced ​​along the baseline. The adjacent guide walls 21 after splicing are fixed by locking components, thus forming a whole, thereby achieving better overall support stability. After the gas flow is completed, the second frame is flipped above the first frame by the flipping device, and the support device is closed at the same time. The adjacent guide walls 21 are then symmetrically arranged about the baseline and fixed by locking components. This makes the two guide walls 21 structurally connected to form a whole, thus making the overall structure more compact. Moreover, due to the symmetrical arrangement, the stress on the whole is uniform during hoisting and transportation, effectively avoiding the problem of uneven stress on the overall structure due to the inability to flip the structure, which would lead to inconvenience and time-consuming hoisting and transportation.
