The invention relates to the technical field of aerodynamics of unmanned aerial vehicles, in particular to a device and a method for testing transient composite working condition aerodynamic characteristics of a fixed-wing unmanned aerial vehicle. According to the device, the four electric cylinders are used as the actuators, the pitching angle and the rolling angle of the unmanned aerial vehicle can be dynamically adjusted by controlling the elongation change of the four electric cylinders, and the defect that an existing fixed-wing unmanned aerial vehicle aerodynamic characteristic testing device can only conduct static pure working condition testing is overcome. The bottom frame, the front vertical frame and the rear vertical frame can be built through sectional materials, the structure is simple, cost is low, assembling is convenient, an electric cylinder is used as an actuator, the control method is simple and convenient, and control precision is high.

    本发明涉及无人机空气动力学技术领域,具体涉及一种固定翼无人机瞬态复合工况气动特性测试装置及方法。本发明装置使用四电缸作为作动器,能够实现通过控制四电缸的伸长量变化从而实现无人机俯仰角度与横滚角度的动态调节,克服了现有固定翼无人机气动特性测试装置只能进行静态纯工况测试的不足。所用底架、前后立架均可采用型材搭建,结构简单,成本较低,组装方便,且使用电缸作为作动器,控制方法简便,控制精度高。
