Abstract

The invention relates to aerodynamic testing techniques for aircrafts, in particular to a vehicle-mounted aerodynamic testing system for an unmanned aerial vehicle. The vehicle-mounted aerodynamic testing system for the unmanned aerial vehicle comprises a vehicle bearing device, a supporting device and a data collecting device, wherein the vehicle bearing device is used for bearing the pretested unmanned aerial vehicle and driving the pretested unmanned aerial vehicle to conduct uniform linear motion in a predetermined direction; the supporting device is used for fixedly arranging the pretested unmanned aerial vehicle on the vehicle bearing device, and the supporting device has a folding state and an unfolding state; the supporting device is used for adjusting posture of the pretested unmanned aerial vehicle and testing lift force and resistance of the pretested unmanned aerial vehicle in the unfolding state; and the data collecting device is used for collecting the relative inflow velocity during conducting uniform linear motion and the lift force and the resistance of the pretested unmanned aerial vehicle. According to the vehicle-mounted aerodynamic testing system for the unmanned aerial vehicle, the pretested unmanned aerial vehicle can be conveniently installed by operating personnel, the angle of attack of the unmanned aerial vehicle to be tested can be precisely and continuously controlled, and experimental and testing efficiency is improved.

Description

technical field [0001] The invention designs an aircraft aerodynamic testing technology, and in particular relates to a vehicle-mounted aerodynamic testing system for an unmanned aerial vehicle. Background technique [0002] Large-scale, high-altitude and long-endurance solar-powered drones generally have the characteristics of large aspect ratio, small wing load, and low flight speed; aerodynamic characteristic test is one of the main tasks in the design process of this type of aircraft. The aerodynamic test mainly includes test contents such as lift characteristics, drag characteristics, moment characteristics and rudder surface control efficiency, and has the characteristics of large amount of test data and long test period. [0003] At present, the main means of testing the aerodynamic characteristics of UAVs are wind tunnel tests and free flight of scale models. The wind tunnel test has the characteristics of adjustable wind speed and stable flow field, but its constru...
