Abstract
A supersonic aircraft engine, either turbojet or turbofan, having a compressor, a diffuser, a combustion chamber, a turbine, and a nozzle passageway, and a turbine bypass passageway for bypassing compressor exit flow around the turbine. The bypass passageway comprises a plurality of supply pipes, and a flow control valve is mounted in each of the plurality of supply pipes. Under given flight conditions, a predetermined number of these flow control valves are fully closed, while the remaining flow control valves are opened as necessary for the given flight condition to obtain a desired rate of turbine bypass flow. The turbine bypass flow is supersonically mixed with the turbine exit flow during transonic acceleration or discharged externally of the engine housing. The turbine bypass flow is primarily composed of boundary layer air flowing along the inner and outer walls of the diffuser.
