Kombinierter Motor mit integrierten Arbeitsweisen als Ejektor für turbokomprimierte, gekühlte oder verflüssigte Luft, als Staustrahltriebwerk und als Überschall-Staustrahltriebwerk

The multi-mode engine comprises a main stream 1 having an air intake 110, a main combustion chamber 120, and an exhaust nozzle 130, and a secondary stream 2 having movable inlet vanes 161 including circuits 163 for conveying fuel from tank 140 for cooling or liquefying the inlet air, and are capable of being selectively placed in a fully-closed position. The secondary stream further 2 comprises a low temperature compressor 210, an ejector combustion chamber 220, a turbine 230, and a set of retractable nozzles 240 opening out into the main combustion chamber 120 of the main stream 1. The multi-mode engine is capable of operating selectively in an ejector mode using cooled or liquefied turbocompressed air, in a ramjet mode using subsonic combustion, and in a super ramjet mode using supersonic combustion. An additional heat exchanger 170, rocket engine 300, liquid air tank 151, and liquid oxygen tank 152 may be provided. Fuel is supplied to combustion chamber 120 via a nozzle 250.
