为解决微扑翼机进行气动力实验测试的问题,提出了一种基于LABVIEW的微扑翼机实验台测控系统,通过合理的硬件和软件设计,可同时实现扑翼样机的气动特性测试和扑翼流场的观测。该试验台测控系统主要包括气动力测试装置、三维粒子图像测速装置(3D-PIV)和微扑翼样机,通过实验可以获得扑翼样机在扑翼过程中的气动力数据、翅翼扭转角度、扑翼频率、扑翼流场的涡量云图、流线图。实验数据可反映出样机的气动性能,有助于进行具有良好飞行特性的扑翼样机的设计和研究。

To be inconvenient to do the aerodynamic experimental tests for flapping-wing micro air vehicles,this paper presents a kind of test system for micro ornithopter test bench based on LabVIEW software.Through reasonable design of the hardware and software,test system can be used to achieve the aerodynamic characteristics test for the ornithopter and the observation of the flapping-wing flow field.It mainly consists of the aerodynamic testing devices,the three-dimensional particle image velocimetry devices(3D-PIV)and micro ornithopter prototype.The aerodynamic data,the twist angle of the wings,flapping frequency,vorticity diagram of the flapping-wing flow field can be obtained through this test.These experimental datum can reflect the aerodynamic performance of the ornithopter,which are agreat help to the design of the ornithopter and its research.
