摘　　要：针对大尺寸高空飞艇螺旋桨气动力性能数据试验,通过高海拔车载螺旋桨前进的方式可模拟低密度环境不同风速下的螺旋桨风洞试验,故设计组建了高空螺旋桨车载试验测控系统。该系统由稳压电源、伺服电机、拉压传感器构建的二分量天平、超声波风速风向仪和高速数据采集模块等设备组成,并利用基于虚拟仪器(VI)的LABVIEW图形化开发平台实现了实验设备控制及数据采集记录。使用此车载试验测控系统完成了6.8 m螺旋桨的相关试验,并通过试验结果分析证实了该试验方法的可行性。A ground vehicle test system was designed for aerodynamic performance tests of high altitude propeller of airship,which is used to simulate to propeller＇s wind tunnel test at different wind speed in low density circumstance. This system is consisted of stable power supply,servo motors,a two-component balance constructed by tension-compression sensors,ultrasonic anemometer,and high speed data acquisition module,which are loaded on a truck. The graphical programming language LABVIEW for developing virtual instrument was used to realize the test system control and data acquisition. A 6. 8-meter diameter propeller＇s aerodynamic performance tests have been completed with this system and the results prove the feasibility of the test method.
