Research on Starting Control Strategy of Acceleration-regulated Aviation Three-stage Starter-generator Based on High-power Turbofan Engine Load
In the process of starting a high-power turbofan engine,the change of the instantaneous power of the ground electrical power source demanded by the special load torque characteristics has an impact on start-ing reliability and causes problems such as power protection.In response to these challenges,the starting control strategy of the three-stage start-generator based on acceleration regulation was proposed.On the premise of ensuring the successful start of the engine,the acceleration in different speed ranges should be reasonably planned to reduce the torque impact at the initial stage of start and decrease the power demand on the ground electrical power source.Through the simulation analysis and bench-starting tests under the given load condition,the effectiveness of the proposed starting control method was proved,providing a solid foun-dation for the application of aviation three-stage starter-generator system in turbofan engines.
