    摘要: 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.

    摘要: The engine (10) includes a low spool (16) disposed aft of an air inlet (12) and a high spool (34) disposed aft of the low spool (16). An intake reverse-duct (44) is disposed radially outward of the high spool (34) and reverses direction of low pressure compressed air from the low spool (16) into a forward-flow high pressure compressor (40) of the high spool (34). A discharge reverse-manifold (48) directs flow of an exhaust gas stream (50) from a forward-flow low pressure turbine (20) into a rearward-flow direction and into at least one pulse detonation firing tube (54). An annular bypass air duct (72) directs cooling air along the engine (10)—The at least, one firing tube is positioned radially outward of the high spool (34), overlies the high spool (34) and is also positioned within the bypass air duct (72).

    摘要: An afterburner includes an exhaust duct with a fixed area outer nozzle at an aft end thereof, and an ablative inner nozzle therein. The smaller inner nozzle is consumed during reheat operation to expose the larger outer nozzle for increased propulsion thrust.

    摘要: A variable cycle gas turbine engine for commercial supersonic aircraft is provided with variable geometry means to simultaneously control the bypass and pressure ratios for different engine flight conditions wherein the engine may be operated at supersonic speed with a lower bypass and higher pressure ratio than at subsonic speed. The relatively high noise levels generally associated with the supersonic mode of operation for conventional supersonic engines can be significantly reduced by controlling the variable geometry means in a manner which increases the bypass ratio and decreases the pressure ratio of the fan section of the engine. In this manner, supersonic aircraft may approach and take off from airports situated adjacent densely populated areas without unduly disturbing the local residents.

    摘要: An aerospace turbofan engine that injects oxygen-enriched gas from an inlet includes an oxygen-enriched gas injection component, a body structure, an afterburner middle portion and a first afterburner outer ring. An aerospace turbofan engine that injects oxygen-enriched gas from an inlet and an afterburner individually or simultaneously includes an oxygen-enriched gas injection component, a body structure, an afterburner middle portion and a second afterburner outer ring. The aerospace turbofan engines which fully utilize oxygen in the atmosphere for combustion and work in various flight altitude ranges adopt regenerative cooling-type afterburners with acoustic cavity and baffle plates, so that an aircraft can fly to an altitude of 20-50 km and reach a speed of Mach 2-5. Variants of the aerospace turbofan engines are disclosed.
