In the development process of an unmanned aerial vehicle, after the unmanned aerial vehicle is assembled and before the actual trial flight, a flight attitude simulation test needs to be performed totest whether all flight functions of the unmanned aerial vehicle are normal or not and whether all flight performance meets design requirements or not. The unmanned aerial vehicle has pitching, rolling and yawing attitudes in flight, and the maintenance and transformation of each flight attitude on a test table are crucial to the simulation test of the unmanned aerial vehicle. The invention provides a multi-freedom-degree attitude test system for an unmanned aerial vehicle. The multi-freedom-degree attitude test system for the unmanned aerial vehicle comprises a contraction section, a test section, a diffusion section and a fan. Actual wind at different wind power levels is provided through a wind tunnel to disturb an unmanned aerial vehicle attitude test device; the wind power disturbanceis real; meanwhile, an anemograph is used for accurately measuring and outputting a wind speed value; and an obtained test result is accurate. The test system has the advantages that the structure issimple and compact; the occupied space is small; the practicability is high; the operation is simple; and the development process of the unmanned aerial vehicle can be effectively supported and accelerated.

    在无人机的开发过程中,无人机装配完成后、实际试飞之前要进行飞行姿态模拟测试,以测试无人机各飞行功能是否正常,各飞行性能是否达到设计要求。无人机在飞行中有俯仰、滚转和偏航姿态,各种飞行姿态在测试台上的保持和变换对无人机模拟测试至关重要。本发明提供一种无人机多自由度姿态测试系统,包括收缩段、试验段、扩压段和风机,通过风洞来提供不同风力等级的实际风对无人机姿态测试装置进行扰动,风力扰动真实,同时用风速仪准确测量和输出风速值,得出的测试结果准确。本测试系统结构简单、紧凑、占用空间小,实用性强,操作简单,能有效地支撑和加快无人机的开发过程。
