摘　　要：针对某大功率航空涡扇发动机电起动过程中,存在的因特殊负载力矩特性对地面电源瞬时功率需求变化等会影响起动可靠性,引起电源保护等问题,提出了基于加速度调节的三级式电机起动控制策略。在保证发动机起动成功的前提下,对不同速度范围内加速度进行合理规划,减小起动初始阶段的转矩冲击,降低对地面电源的功率需求。通过对该负载情况下仿真分析和台架起动试验,验证了所提起动控制方法的有效性,为航空三级式电机起动/发电系统在涡扇发动机上的应用提供了参考。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 starting 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 foundation for the application of aviation three-stage starter-generator system in turbofan engines.
