HYBRID JET ENGINE Russian patent published in 2006 - IPC F02K7/16 

FIELD: jet engines.

SUBSTANCE: proposed hybrid jet engine has load-bearing casing with sections of rocket and air-jet engines located coaxially. Air-jet engine has turbocompressor with guide blades and working wheels mounted in bearings on body of gas generator. Gas generator is made in form of combustion chamber having housing in form of circular taper envelope connected with load-bearing casing; it includes head bottom part and widened open rear part equipped with flame tube with fuel system injectors located on shear of outlet section of turbocompresor and communicated with it. Housing of turbocompressor in its center portion is assembled from circular sections mounted at spaced relation to each other on combustion chamber by means of guide blades of compressor; it is provided with tail section with taper chamber equipped with swivel doors for closing the outlet section of turbocompressor. Each working wheel consists of working blades interconnected over external ends by means of circular adapter and over internal ends by means of gas receiver mounted on combustion chamber housing. Working compressor blades are hollow and are communicated with interior of circular gas receivers. Combustion chamber housing is provided with outlet holes in zone of circular gas receivers. Connected to outer surface of circular adapter are hollow cylindrical rods which are communicated with cavities of working compressor blades moving in clearances of circular sections with jet drive on their external ends; jet drive forms turbine and feeds fuel combustion products to circular space between turbocompressor housing and load-bearing casing of engine.

EFFECT: possibility of performing flights of flying vehicles in wide range from subsonic to supersonic speeds.
