Entrainment compression system for jet engine

Abstract

A jet engine uses an entrainment compressor within a housing to compress intake air. The compressed air is routed to a combustion chamber where it is ignited. A portion of the exhaust is directed outward for thrust and a portion is rerouted through an energy feedback system to one or more entrainment nozzles within the compressor housing. The exhaust acts as motive fluid to mix with the intake air. The motive fluid imparts energy to create the compressive capability of the jet engine. A startup system is configured to generate startup motive fluid selectively routed through some or all of the entrainment nozzles to initiate a stable idle flow of motive fluid. Some of the entrainment nozzles may include combustion chambers to further enhance the compressive capability of the jet engine.
