The invention relates to the technical field of aircraft auxiliary power control, and discloses an aircraft auxiliary power system which is characterized in that a turbine (3) can input mechanical energy generated in the turbine (3) to a second generator (7) while depressurizing first bleed air output by a gas turbine engine (2); the compressor (4) can boost the pressure of the first bleed air under the action of the motor (8); the first generator (6) and/or the second generator (7) can charge the energy storage battery (5). Redundant electric energy in the system can be stored, redundant mechanical energy in the system can be converted into electric energy to be stored, the electric energy is released when the aircraft needs high power, and the utilization rate of the energy in the system is increased; and the pressure of output bleed air can be adjusted under the condition that the working state of the gas turbine engine (2) is not changed, all components in the system are matched with one another, so that different requirements of the aircraft for the bleed air pressure and power are met, the system control method is simple, and the working modes are rich.

    本发明涉及飞机辅助动力控制技术领域,公开了一种飞机辅助动力系统,涡轮机(3)能够将燃气涡轮发动机(2)输出的第一引气进行降压的同时,将其内部产生的机械能输入至第二发电机(7);压缩机(4)能够在电动机(8)的作用下对第一引气进行升压;第一发电机(6),和/或第二发电机(7)能够为储能电池(5)充电。本发明能够储存系统中多余的电能并将系统中多余的机械能转换为电能后储存,在飞机需求功率较高时释放电能,提高了系统中能量的利用率;并且能够在不改变燃气涡轮发动机(2)的工作状态下调节输出引气的压力,系统中的各个组成部分相互配合,从而适应飞机对引气压力及功率的不同需求,系统控制方法简单,工作模式丰富。
