Development of Experimental Teaching Platform for Performance Testing of Small UAV Rotor Power System
To meet the need of unmanned aerial vehicle(UAV)system teaching for major of traffic transportation in the civil aviation college,a performance testing experimental platform for small UAV rotor power system is designed and developed.This platform consists of the main bench system,the control and data acquisition system and data display and analysis system.The performance testing experiments of hovering and forward flight state are conducted based on the experimental platform.The test results show that the main performance parameters of the rotor power system can be obtained in real-time using this platform with the wind tunnel system.The measurement errors of aerodynamic thrust and torque directly measured are less than 0.5%,the errors of current and voltage are 0.2%,and the errors of propeller's force efficiency and system's force efficiency indirectly measured are all less than 5%.The platform can be applied to the experimental teaching of performance analysis of small rotor UAV power system.
