Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of turbulence experimental devices for aircraft research, specifically a turbulence experimental device for electric aircraft research. Background Technology
[0002] Atmospheric turbulence is an important form of atmospheric motion. Its presence significantly enhances the vertical and horizontal exchange of momentum, heat, water vapor, and pollutants in the atmosphere, far exceeding the exchange intensity of molecular motion. Atmospheric turbulence also interferes with the propagation of light waves, sound waves, and electromagnetic waves in the atmosphere. To test aircraft safety, turbulence simulation experiments are often conducted on aircraft.
[0003] In existing turbulence experiments, most aircraft models are fixed. Since aircraft adjust their altitude during flight, existing experimental devices cannot adjust their altitude in all directions, thus reducing the efficiency of turbulence experimental devices. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3 This utility model provides a technical solution: a turbulence experimental device for electric aircraft research, including a workbench 1, a turbulence simulator 2 fixedly installed on the workbench 1, a cover 3 fixedly installed on the turbulence simulator 2, a support platform 4 provided inside the cover 3, an adjustment component provided on the support platform 4, a fixing component provided on the adjustment component, and a door panel 5 provided on the cover 3.
[0019] In this embodiment, the adjustment assembly includes a cylinder 6, which is fixedly mounted on a support platform 4. A motor 7 is fixedly mounted on the lower wall of the workbench 1, and a lead screw 8 is fixedly mounted on the drive end of the motor 7. The lead screw 8 passes through the workbench 1 and the support platform 4 and is located inside the cylinder 6. The upper end of the cylinder 6 has an open structure, and a moving rod 9 is inserted into the upper end of the cylinder 6. Sliding grooves 10 are respectively opened on the two inner side walls of the cylinder 6. Sliding blocks 11 are slidably installed in the sliding grooves 10. The moving rod 9 is fixedly installed between the sliding blocks 11. A threaded groove is opened at the lower end of the moving rod 9, and the lead screw 8 is engaged in the threaded groove. A support plate 12 is movably mounted on the upper end of the moving rod 9, and an angle adjustment part is provided between the moving rod 9 and the support plate 12.
[0020] In this embodiment, the angle adjustment part is further configured to include a pair of electric push rods 13, one end of the pair of electric push rods 13 is hinged to the moving rod 9, and the other end of the electric push rods 13 is hinged to the lower wall of the support plate 12.
[0021] In this embodiment, a connecting frame 14 is fixedly installed on the lower wall of the workbench 1, and the motor 7 is fixedly installed on the connecting frame 14.
[0022] In this embodiment, the fixing component includes a U-shaped plate 15, with ear plates 16 fixedly installed on both sides of the U-shaped plate 15. The ear plates 16 have a first through hole, and the bearing plate 12 has a pair of second through holes. The first through hole and the second through hole correspond to each other. A fixing bolt 17 is inserted between the first through hole and the second through hole. A fastening nut 18 is screwed onto the lower end of the fixing bolt 17. The U-shaped plate 15 has a threaded hole, and a limit bolt 19 is screwed into the threaded hole.
[0023] In this embodiment, the lower end of the limiting bolt 19 is rotatably mounted with a top plate 20, and a rubber pad 21 is fixedly mounted on the lower wall of the top plate 20.
[0024] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0025] Example: As shown in the accompanying drawings, during use, the door panel 5 is opened, and the airplane model is placed on the support plate 12. The U-shaped plate 15 is then placed on the airplane model, aligning the first through hole with the second through hole. The fixing bolt 17 is inserted into the first and second through holes, and the fastening nut 18 is screwed onto the fastening bolt, thus fixing the U-shaped plate 15 and initially securing the airplane model. Then, the limiting bolt 19 is rotated, advancing along the path of the threaded hole and pushing the top plate 20. The top plate 20 pushes the rubber pad 21, which then contacts the airplane model. Pressure is applied to limit the airplane model's movement (the rubber pad 21 provides better friction for the limiting bolt 19 and deforms during the downward pressure, better conforming to the airplane model). The door is then closed. Plate 5, at this time, the turbulence simulator 2 is started (the turbulence simulator 2 is Lexitek's turbulence simulator 2). The turbulence simulator 2 generates turbulence and blows it towards the aircraft model, thereby conducting turbulence detection experiments on the aircraft. When it is necessary to adjust the height of the aircraft, the motor 7 is started. The drive end of the motor 7 drives the lead screw 8 to rotate. Since the lead screw 8 and the moving rod 9 are engaged through the threaded groove, the rotation of the lead screw 8 has a driving effect on the moving rod 9. The moving rod 9 moves along the path of the slide groove 10 under the action of the fast point, thereby adjusting the height of the aircraft model. When it is necessary to adjust the pitch angle of the aircraft model, the electric push is started. One of the telescopic ends of the pair of electric push rods 13 extends, and the other telescopic end of the pair of electric push rods 13 retracts, thereby causing the support plate 12 to adjust the angle, thereby adjusting the pitch angle of the aircraft model.
