The invention belongs to the field of unmanned aerial vehicle aerodynamics, and particularly relates to a device and a method for testing transient longitudinal aerodynamic characteristics of a fixed-wing unmanned aerial vehicle. According to the scheme, the electric cylinder is used as an actuator, and the pitching angle of the unmanned aerial vehicle can be dynamically adjusted by controlling the elongation change of the electric cylinder. The supporting legs, the bottom frame, the front vertical frame and the rear vertical frame which are used by the device can be built by adopting profiles, and the device is simple in structure, low in cost and convenient to assemble.

    本发明属于无人机空气动力学领域,具体涉及一种固定翼无人机瞬态纵向气动特性测试装置及方法。本发明装置使用电缸作为作动器的方案,能够实现通过控制电缸的伸长量变化从而实现无人机俯仰角度的动态调节。本发明装置所用支腿、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。
