Research and Design of Ground Testing System for Propeller Electric Propulsion Systems

For the ground performance testing problem of airship propeller propulsion system, based on the operational principle of test method and the key technologies of the ground propulsion systems, a design of on-line testing system is proposed by high power-density asynchronous motor driven. This testing system can improve the measurement accuracy and efficiency. In this paper, the technological scheme, hardware structure and software structure of the test system are introduced, which provide effective research route and foundation for propulsion systems testing.
