    • An integrated bleed air and engine starting system for an engine utilizes a flow multiplier air turbine starter to provide bleed air supply to an ECS as well as starting an engine. The system includes an air turbine starter subsystem and an air flow subsystem. The air turbine starter subsystem includes a compressor, a turbine, and a common shaft fixed between the compressor and turbine. Also provided is a gear coupled to a gearbox which links the engine with a shaft, as well as a variable nozzle valve intermediate the turbine and engine. The air flow subsystem comprises a diverter valve downstream of the turbine, an isolation valve intermediate the turbine and an auxiliary power unit, and a check valve downstream of the compressor and turbine. A fan is in air flow communication with the compressor and engine.
    • 用于发动机的集成放气和发动机起动系统利用流量倍增器空气涡轮起动器向ECS提供放气供应并启动发动机。 该系统包括一个空气涡轮启动器子系统和一个空气流量子系统。 空气涡轮机起动器子系统包括压缩机,涡轮机和固定在压缩机和涡轮机之间的公共轴。 还提供了连接到将发动机与轴连接的齿轮箱的齿轮,以及涡轮和发动机之间的可变喷嘴阀。 空气流子系统包括位于涡轮下游的分流阀,位于涡轮和辅助动力单元中间的隔离阀,以及位于压缩机和涡轮下游的止回阀。 风扇与压缩机和发动机处于气流连通。
