Description

Technical Field

[0001] This utility model relates to the field of simulation device technology, and in particular to a device for simulating aircraft wing lift and stall phenomena. Background Technology

[0002] Aircraft wings are an important component of an aircraft, and their main function is to generate lift to support the aircraft in flight. The wings are installed on both sides of the fuselage and are usually divided into two symmetrical wing surfaces. Before the aircraft wings are installed on the fuselage, their lift and stall conditions are tested, which requires the use of aircraft wing lift and stall simulation devices.

[0003] Existing aircraft wing lift and stall simulation devices typically place an aircraft wing model in a wind tunnel to detect its lift and stall conditions. However, wind tunnels are slow to change wind direction and cannot simulate transient airflow such as gusts and turbulence. Therefore, we propose an aircraft wing lift and stall simulation device that uses a longitudinal / lateral adjustment mechanism to change the spatial attitude of the air outlet device, thereby achieving airflow vector control.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Example 1 like Figure 1-4 As shown: This application provides an aircraft wing lift and stall simulation device, which includes a device body (1); a simulation chamber (2) is provided inside the device body (1); a wing fixing structure is provided in the simulation chamber (2) for fixing the wing to be tested; an air outlet device, a longitudinal adjustment mechanism, and a lateral adjustment mechanism are rotatably arranged in the simulation chamber (2); the lateral adjustment mechanism is driven to the air outlet device and is used to drive the angle of the air outlet device in a first direction; the longitudinal adjustment mechanism is driven to the lateral adjustment mechanism and is used to drive the position of the lateral adjustment mechanism in a second direction, thereby driving the angle of the air outlet device in the second direction.

[0032] In this embodiment, existing data acquisition and data analysis devices are also included. These devices are directly purchased and no improvements have been made to them in this application. During use, after the wing is placed in the simulation cabin, subsequent analysis can be performed using the data acquisition device and data analyzer used for wing detection.

[0033] Furthermore, in this embodiment, the following technical solution is provided: It includes a device body 1, with a simulation chamber 2 inside the device body 1, where simulation experiments can be conducted. A mounting groove 3 is provided on the front of the device body 1, and a first drive motor 301 is installed inside the mounting groove 3. The first drive motor 301 can drive the fan blades 306 to rotate. A first rotating ball 302 is sleeved around the first drive motor 301. A first rotating groove 303 is provided on the inner wall of the mounting groove 3 corresponding to the first drive motor 301. The first rotating ball 302... The device can rotate within the first rotating slot 303, making it easier for the first drive motor 301 to change orientation. A mounting cover 4 is fixed to the front of the main body 1. A second drive motor 401 is mounted on the top of the mounting cover 4. A longitudinal linear guide rail 402 is provided on the inner wall of the mounting cover 4 corresponding to the second drive motor 401. A longitudinal lead screw 403 is rotatably connected inside the longitudinal linear guide rail 402. A longitudinal slider 404 is fitted around the longitudinal lead screw 403 and inside the longitudinal linear guide rail 402. The second drive motor 401 can drive the longitudinal linear guide rail 401 to rotate within the longitudinal linear guide rail 402. The lead screw 403 rotates inside the longitudinal linear guide 402. As the lead screw 403 rotates, it rotates relative to the thread inside the longitudinal slider 404, applying a force to the longitudinal slider 404. This allows the longitudinal slider 404 to move within the longitudinal linear guide 402. A first limiting block 405 and a second limiting block 406 are provided on the longitudinal linear guide 402. The longitudinal lead screw 403 passes through both the first limiting block 405 and the second limiting block 406, and is respectively positioned relative to both the first limiting block 405 and the second limiting block 406. 406 Rotational engagement; the first limiting block 405 and the second limiting block 406 are used to limit the longitudinal movement distance of the longitudinal slider 404; during use, the first limiting block 405 and the second limiting block 406 are used to limit the maximum upward movement distance and the maximum downward movement distance of the longitudinal slider 404. In this way, when adjusting the vertical angle of the first drive motor 301, it can be ensured that the first rotating groove 303 and the first rotating ball 302 are always kept within the effective release range, and the first rotating ball 302 is prevented from disengaging from the first rotating groove 303.A transverse linear guide 5 is mounted on the side of the longitudinal slider 404 away from the longitudinal linear guide 402. A transverse lead screw 501 is rotatably connected inside the transverse linear guide 5. A transverse slider 502 is sleeved around the transverse lead screw 501 and inside the transverse linear guide 5. When the transverse lead screw 501 rotates, it rotates relative to the thread inside the transverse slider 502, applying a force to the transverse slider 502. This allows the transverse slider 502 to move relatively easily inside the transverse linear guide 5, thereby driving the rotating seat 503 to move. A rotating seat 503 is fixed on the side of the transverse slider 502 away from the transverse linear guide 5. A telescopic rod 304 is mounted on the back of the first drive motor 301 corresponding to the rotating seat 503. A second rotating ball 305 is mounted on the end of the telescopic rod 304 away from the first drive motor 301. A corresponding second rotating ball 305 is mounted on the outer wall of the rotating seat 503. A second rotating groove 504 is provided on one side of the first drive motor 305, allowing the second rotating ball 305 to rotate within the second rotating groove 504, thus facilitating a convenient change in the orientation of the first drive motor 301. A third limiting block 506 and a fourth limiting block 507 are provided on the inner wall of the transverse linear guide rail 5. The transverse lead screw 501 passes through the third limiting block 506 and the fourth limiting block 507 respectively, and rotatably engages with them. The third limiting block 506 and the fourth limiting block 507 limit the transverse movement distance of the transverse slider 502. Thus, when adjusting the angle of the first drive motor 301 in the horizontal direction, it ensures that the first rotating groove 303 and the first rotating ball 302 remain within the effective release range, preventing the first rotating ball 302 from disengaging from the first rotating groove 303.

[0034] Example 2 like Figure 1-4 As shown, it also includes: a wing fixing member 6; the end of the wing fixing member 6 is used to clamp the wing to be tested and place the wing to be tested inside the simulation cabin 2, the wing fixing member 6 can rotate relative to the simulation cabin 2 to adjust the angle of the wing to be tested; an angle indicator is provided on the outside of the simulation cabin 2, the angle indicator 7 is used to indicate the angle of the wing fixing member 6.

[0035] In this embodiment, the purpose of the wing fixing component 6 is to secure the wing. Specifically, one end of the wing fixing component 6 can be equipped with a claw, which can be readily purchased. The claw is used to secure the end of the wing; this application does not represent an initial improvement on this. Furthermore, the end of the wing fixing component 6 extends through the simulation chamber 2 and to the outside of the simulation chamber 2, facilitating angle adjustment of the wing to be tested within the simulation chamber 2 by the user. To facilitate the operator in obtaining the current angle of the wing to be tested, the aforementioned angle indicator 7 is also provided. A pointer is set on the wing fixing component. Based on the initial fixed wing angle and the relationship between the pointer and the wing fixing component—for example, if the horizontal direction of the wing is parallel to the pointer—the wing rotates by the same number of degrees as the pointer. The current angle of the wing to be tested can be determined using the relationship between the pointer and the angle indicator, making the operation simple.

[0036] Support bases 101 are installed at the bottom of the main body 1 near the corners. The support bases 101 are made of rubber and can effectively help fix the main body 1.

[0037] The first rotating ball 302 is adapted to the first rotating groove 303, and the first rotating ball 302 and the first rotating groove 303 are rotatably connected. Through the rotatable connection between the first rotating ball 302 and the first rotating groove 303, the first drive motor 301 can rotate more freely, thereby changing the wind direction more quickly.

[0038] A fan blade 306 is installed on the output end of the first drive motor 301. The fan blade 306 is adapted to the simulation chamber 2 and the mounting slot 3. By adapting the fan blade 306 to the simulation chamber 2 and the mounting slot 3, the first drive motor 301 can more conveniently blow air into the interior of the simulation chamber 2 when it drives the fan blade 306 to rotate.

[0039] The output end of the second drive motor 401 extends to the longitudinal linear guide rail 402 and is fixedly connected to the longitudinal lead screw 403. The longitudinal slider 404 is slidably connected to the longitudinal linear guide rail 402 and threadedly intersects with the longitudinal lead screw 403. Through the slidable connection between the longitudinal slider 404 and the longitudinal linear guide rail 402 and the threadedly intersects with the longitudinal lead screw 403, the longitudinal slider 404 can move relatively easily inside the longitudinal linear guide rail 402 when the second drive motor 401 drives the longitudinal lead screw 403 to rotate.

[0040] The transverse slider 502 is slidably connected to the transverse linear guide 5 and threadedly intersects with the transverse lead screw 501. Through the slidable connection between the transverse slider 502 and the transverse linear guide 5 and the threaded intersection with the transverse lead screw 501, the transverse lead screw 501 can drive the transverse slider 502 to move within the transverse linear guide 5 when it rotates.

[0041] The second rotating ball 305 is adapted to the second rotating groove 504. The second rotating ball 305 and the second rotating groove 504 are rotatably connected. Through the rotatable connection between the second rotating ball 305 and the second rotating groove 504, when the rotating seat 503 changes position, it can drive the second rotating ball 305 to rotate inside the second rotating groove 504, thereby changing the orientation of the first drive motor 301.

[0042] A third drive motor 505 is installed on the left side of the transverse linear guide 5. The output end of the third drive motor 505 extends into the interior of the transverse linear guide 5 and is fixedly connected to the transverse lead screw 501. By extending the output end of the third drive motor 505 into the interior of the transverse linear guide 5 and fixing it to the transverse lead screw 501, the third drive motor 505 can drive the transverse lead screw 501 to rotate inside the transverse linear guide 5 after it is turned on, thereby making it easier to drive the transverse slider 502 to move inside the transverse linear guide 5.

[0043] The working process of this utility model is as follows: When using an aircraft wing lift and stall simulation device, the operator can first turn on the second drive motor 401, which will drive the longitudinal lead screw 403 to rotate inside the longitudinal linear guide rail 402. This will facilitate the movement of the longitudinal slider 404 and the transverse linear guide rail 5, thereby changing the horizontal height of the rotating seat 503. At the same time, the operator can also turn on the third drive motor 505, which will drive the transverse lead screw 501 to rotate inside the transverse linear guide rail 5. This will change the transverse position of the transverse slider 502 and the rotating seat 503, allowing the second rotating ball 305 to rotate inside the second rotating groove 504. While the second rotating ball 305 rotates, the telescopic rod 304 can retract appropriately according to the position of the second rotating ball 305 to apply force to the first drive motor 301. This, in conjunction with the rotation of the first rotating ball 302 inside the first rotating groove 303, changes the orientation of the first drive motor 301. Compared with existing aircraft wing lift and stall simulation devices, this device can more quickly and naturally simulate complex and changeable weather environments when wind direction needs to be changed, improving the efficiency and practicality of the aircraft wing lift and stall simulation device during simulation.
