[0031] Aerodynamic performance is an important indicator in the development of aircraft. Wind field testing is an important way to verify and evaluate the aerodynamic performance of the device. In order to verify the impact of different working conditions on the aircraft, it is often necessary to test the working conditions of the aircraft in various wind fields.

[0032] At present, wind field tests for aircraft generally use wind tunnels to generate wind fields, but traditional wind tunnels used for full-scale aircraft testing are large in size and expensive. In addition, the wind field generated by traditional wind tunnels is relatively simple and is generally used to simulate fluid mechanics for fixed-wing aircraft. It is difficult to simulate the scenarios when rotary-wing UAVs encounter complex flight conditions such as gusts, shear winds, and time-varying winds.

[0033] In order to better evaluate and improve the aerodynamic performance of related devices under complex and changeable working conditions and observe the flow field generated when the rotor UAV is hovering, it is of great significance to design a flow field generating device that can generate complex and changeable flow fields simulating multi-rotor UAVs.

[0034] In this regard, the present application proposes a wind field generating device, which generates a wind field by combining independent wind power units 400 into a wind matrix; each wind power unit 400 can be disassembled and assembled as needed, and the wind force and wind direction of each wind power unit 400 can also be controlled individually, thereby changing the airflow state in the local area, and simulating complex wind field conditions.

[0035] Reference Figure 1 and Figure 2The wind field generating device in the embodiment of the present application includes a fixing frame 100, a connecting member 300, a wind power unit 400 and a control console 500. The fixing frame 100 is the main structure of the wind field generating device, which supports and protects other components. The connecting member 300 is used to install the wind power unit 400 to the fixing frame 100. The wind power unit 400 is used to generate wind power, and multiple wind power units 400 can generate a wind field when started at the same time. The control console 500 is used to control each wind power unit 400 to generate different types of wind fields to meet various wind field test requirements of the rotor UAV.

[0036] Specifically, a plurality of equally spaced fixing plates 200 are arranged in the fixing frame 100, and the number of connecting members 300 is multiple and all of them can be detachably mounted on the fixing plates 200. In order to prevent the fixing frame 100 from being pushed down by the reaction force of the airflow after starting each wind power unit 400, the fixing frame 100 also includes a wind field section 110 and a control section 120 that are interconnected. The fixing plates 200, the connecting members 300 and the wind power units 400 are all arranged in the wind field section 110, which is used to generate airflow for testing the rotor drone. The console 500 is installed in the control section 120, which is used to store the control components of the wind field generating device.

[0037] Furthermore, the control unit 120 is disposed at the bottom of the wind farm unit 110, so that the console 500 is disposed at the bottom of the wind farm generating device, which is used to move the center of gravity of the wind farm generating device downward to improve the structural stability. Moreover, in a top-down perspective, the shadow area of ​​the control unit 120 is larger than the shadow area of ​​the wind farm unit 110, so that the contact area with the ground is increased by the control unit 120, thereby reducing the overturning risk of the wind farm generating device.

[0038] Furthermore, the fixing frame 100 further includes a diagonal bracing beam 130. The diagonal bracing beam 130 is tilted, and its two ends are respectively connected to the wind farm unit 110 and the control unit 120 to form a triangular structure, which plays a role in improving the structural strength of the fixing frame 100 and reducing the risk of the fixing frame 100 overturning.

[0039] Reference Figure 3 The wind power unit 400 specifically includes a motor 410 and a rotor 420. The motor 410 is detachably mounted on the end of the connector 300. The output shaft of the motor 410 drives the rotor 420 to rotate. The wind direction generated can be changed by changing the installation direction of the rotor 420. There are multiple wind power units 400 and they are arranged in a matrix. The number of wind power units 400 can be increased or decreased according to the test requirements, and the installation position of each wind power unit 400 can also be selected on each fixing plate 200 according to the test requirements.

[0040] The detachable connection between the motor 410 and the connector 300 may be a bolt connection, a snap connection, a Velcro connection, etc. In this embodiment, the motor 410 is connected to the connector 300 by bolts.

[0041] The control console 500 is electrically connected to the motors 410 of each wind unit 400 through wires and can control them individually, so as to adjust the start and stop and rotation speed of each motor 410, thereby obtaining more varied wind field forms to meet different wind field test requirements.

[0042] Furthermore, a guard plate 240 is installed on the outer side of the fixing plate 200, and a cavity is reserved between the fixing plate 200 and the guard plate 240, and the cavity is used to allow the wires connecting the console 500 and the motor 410 to pass through. Therefore, the wires extending from the motor 410 can be connected to the console 500 through the cavity, preventing the wires from being exposed to the outside and avoiding accidents caused by the wires being scratched by the rotating rotor 420.

[0043] Specifically, refer to Figure 4 The console 500 includes a power supply 510, a communication module 520 and a control module 530. The power supply 510 is used to supply power to each motor 410, the communication module 520 is used to interconnect with a remote terminal device (such as a mobile phone, a computer or a tablet computer), and the control module 530 is used to control the start and stop, rotation direction and speed of each motor. In actual work, the power supply 510 continuously supplies power to each motor 410, and after receiving the command issued by the remote terminal device, the communication module 520 transmits the command to the control module 530, and the control module 530 drives each motor 410 to perform corresponding actions, thereby completing the generation of different wind fields.

[0044] For the specific connection mode of each wind unit 400 in the wind farm generating device, the present application proposes two possible embodiments. It should be noted that the invention is not limited to the embodiments, and those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present application.

[0045] First embodiment:

Thus, each wind power unit 400 is only provided on one side of the fixing frame 100 .

[0047] The wind farm generating device further includes an L-shaped connecting plate 600, and two mutually perpendicular side surfaces of the L-shaped connecting plate 600 are respectively abutted against the fixing plate 200 and the connecting member 300. The L-shaped connecting plate 600, the fixing plate 200 and the connecting member 300 are all provided with fixing holes for bolts to pass through, so that the L-shaped connecting plate 600 can be fixedly connected with the fixing plate 200 and the connecting member 300 by bolts.

[0049] Furthermore, the middle portion of the connector 300 is snapped into the fixing groove 230 , and wind power units 400 are installed at both ends of the connector 300 , thereby further increasing the density of the wind power units 400 per unit area, enhancing the wind force of the wind farm, and making full use of the space in the fixing frame 100 .

The fixing plate 200 is provided with a plurality of fixing grooves 230 equidistantly on the first side and the second side thereof along the length direction thereof, and the connecting member 300 is snapped into the fixing groove 230 to achieve position limiting. Thus, wind power units 400 are provided on both sides of the fixing frame 100. The wind power units 400 located on both sides of the fixing frame 100 can generate the same wind direction to superimpose the two airflows, thereby increasing the wind force; or, the wind power units 400 located on both sides of the fixing frame 100 can also generate opposite wind directions to counteract the two airflows, thereby generating turbulence.

[0052] The wind farm generating device further includes an L-shaped connecting plate 600, and two mutually perpendicular side surfaces of the L-shaped connecting plate 600 are respectively abutted against the fixing plate 200 and the connecting member 300. The L-shaped connecting plate 600, the fixing plate 200 and the connecting member 300 are all provided with fixing holes for bolts to pass through, so that the L-shaped connecting plate 600 can be fixedly connected with the fixing plate 200 and the connecting member 300 by bolts.

[0053] Furthermore, the number of L-shaped connecting plates 600 can be increased or decreased according to actual conditions, and the common connection of multiple L-shaped connecting plates 600 can enhance the connection strength and connection stability between the connecting member 300 and the fixing plate 200. In this embodiment, the number of L-shaped connecting plates 600 is four.

[0054] Furthermore, the middle portion of the connector 300 is snapped into the fixing groove 230 , and wind power units 400 are installed at both ends of the connector 300 , thereby further increasing the density of the wind power units 400 per unit area, enhancing the wind force of the wind farm, and making full use of the space in the fixing frame 100 .

[0055] The following is an introduction to the working process of the wind field generating device:
