The invention relates to the technical field of pneumatic measurement, and particularly discloses a fixed-wing unmanned aerial vehicle crosswind effect aerodynamic wind tunnel test device and method, and the device comprises a wind tunnel device used for providing a crosswind condition, and a rotating disc used for supporting an unmanned aerial vehicle to carry out an experiment. The turntable is arranged between a wind tunnel contraction section and a wind tunnel diffusion section of the wind tunnel device; a hydraulic cylinder for adjusting the attack angle of the wings of the unmanned aerial vehicle is arranged on the turntable; the electric turntable is used for driving the turntable to rotate so as to adjust the horizontal angle of the unmanned aerial vehicle; the controller is used for controlling the electric turntable; and a pneumatic balance for measuring pneumatic characteristics is arranged between the turntable and the electric turntable. The device can automatically realize aerodynamic force measurement of the unmanned aerial vehicle under crosswind, does not need manual operation, has the characteristics of good stability, high precision and high test efficiency, and can measure other physical quantities such as aerodynamic noise, velocity field and the like at the same time.

    本发明涉及气动测量技术领域,具体公开了一种固定翼无人机侧风效应气动力风洞试验装置及其方法,该装置包括用于提供侧风条件的风洞装置、用于支撑无人机进行实验的转盘;所述转盘设置在所述风洞装置的风洞收缩段与风洞扩散段之间;并且转盘上设置有用于调节无人机机翼攻角的液压缸;还包括用于驱动转盘转动从而调整无人机水平角度的电动转台以及用于控制电动转台的控制器;所述转盘与电动转台之间设置有用于测量气动特性的气动天平。本发明可自动实现无人机在侧风下的气动力测量,不需要手动操作,具有稳定性好、精度高、试验效率高特点,同时可以兼顾气动噪声、速度场等其它物理量的测量。
