METHOD OF ORGANISING WORKING PROCESS IN TURBOJET ENGINE WITH CONTINUOUSLY-DETONATING COMBUSTION CHAMBER AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC F02K7/02 

FIELD: engines and pumps.

SUBSTANCE: method of organising working process in a continuously-detonating combustion chamber of turbojet engine comprises a two-stage conversion of fuel chemical energy into useful mechanical work and jet stream kinetic energy. One or more self-sustaining detonation waves are initiated in an annular combustion chamber during the implementation of the method, followed by conversion of fuel chemical energy partly into thermal and partly into kinetic energy during its burning in a continuously-detonating mode in the annular combustion chamber at an elevated average pressure obtained by the compressor, then thermal and kinetic current energies are partly converted into mechanical energy by the turbine, transmitting torque to the compressor, as well as to other auxiliary units, and into jet stream kinetic energy by jet nozzle. The turbine torque is produced by one or more oblique shock waves penetrating from the combustion chamber in the upward flow direction, moving in the medium of one or more self-sustaining detonation waves, continuously circulating in the annular combustion chamber, while hot products of continuously-detonating combustion are directed into the environment directly via the jet nozzle. The turbojet engine for method implementation comprises an inlet device, a compressor, a detonation initiator, an annular combustion chamber, a turbine and an outlet jet nozzle. The turbine is positioned upstream of the annular combustion chamber and the outlet jet nozzle is mounted downstream of the latter.

EFFECT: inventions will enable to increase efficiency of working process in a turbojet engine.
