The invention discloses an online power management method for an aviation series hybrid electric propulsion system. The aviation series-connection hybrid electric propulsion system comprises an aero-engine, a generator, a battery, a motor, a transmission and a propeller, # imgabs0 # efficiency is introduced into the aviation series-connection hybrid electric propulsion system as an evaluation index for the first time, and a system power management scheme is optimized in combination with the rotating speed of a variable power turbine. Compared with the prior art, the method has the advantages that # imgabs 1 # efficiency of the aero-engine can be improved, # imgabs 2 # loss can be reduced, the optimal scheme of expected power distribution of the aero-engine and the battery under the determined voyage is obtained, and the performance of the hybrid electric propulsion aircraft is improved.

    本发明公开了一种航空串联混合电推进系统在线功率管理方法。所述航空串联混合电推进系统包括航空发动机、发电机、电池、电机、传动及推进器,本发明方法首次在航空串联混合电推进系统中引入#imgabs0#效率作为评价指标,并结合可变动力涡轮转速进行系统功率管理方案的优化。相比现有技术,本发明能够提高航空发动机的#imgabs1#效率,减少#imgabs2#损失,得到确定航程下航空发动机与电池期望功率分配的最优方案,提升混合电推进飞行器性能。
