초록

An integrated bleed air and engine starting system for an engine utilizes an innovative flow multiplier air turbine starter to provide bleed air supply to an ECS as well as starting an engine. The technique reduces bleed air consumption by mixing fan stage air and high stage air for ECS fresh air usage. It also can eliminate or reduce the size of the precooler heat exchanger. 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 ...
