METHOD OF AND DEVICE FOR CREATING REACTIVE THRUST IN FORM OF COMBINATION AIR JET ENGINE Russian patent published in 2006 - IPC F02K3/02 F02C3/32 

FIELD: aircraft engineering.

SUBSTANCE: method of creating reactive thrust of turbojet engine for starting, acceleration and flying of aircraft comes to compression of air by compressor driven by gas turbine, combustion of fuel in combustion chamber and additional combustion of fuel in outlet combustion chamber placed before reaction nozzle. Reactive thrust is created by compressed gas passing through reaction nozzle. After acceleration of aircraft to required flying speed, ramjet engine is used, with air preliminarily compressed in engine owing to velocity head and delivering it into outlet combustion chamber from sides bypassing compressor and thus creating radially directed flows. Additionally compression of flow is done in outlet combustion chamber for which purpose flows of compressed air created owing velocity head are directed from periphery to center with their collision in central part of outlet combustion chamber and resulting relative braking and conversion of kinetic energy into additional compression. Additional compression of fuel takes place in area of higher compression of air.

EFFECT: reduced fuel consumption of high flying speeds.
