摘　　要：针对旋翼桨叶表面非定常载荷测量与分析问题,提出一套风洞试验的完整技术方案。采用内嵌传感器的设计方案,研制多通道旋转数据采集器,使用外时钟和外触发的同步采样方法,实现旋翼在运动中按等角度间隔次重复采样功能,解决了旋翼方位角和样本数据的同步性问题。风洞试验结果验证了该项试验技术的可行性。In order to measure and analyze the unsteady loads on the rotor blade surface, a complete technical scheme of wind tunnel test is proposed. A multi-channel rotary data acquisition device is developed based on the design scheme of embedded sensors, and the synchronous sampling method of external clock and external trigger is used to realize the function of repeated sampling at equal angle intervals during the movement of the rotor, thus solving the synchronization problem between the azimuth angle of the rotor and the sample data. The wind tunnel test results verify the feasibility of the test technology.
