METHOD OF FUNCTIONING OF SUPERSONIC PULSING DETONATION STRAIGHT-JET ENGINE Russian patent published in 2015 - IPC F02K7/14 F02K7/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to methods of functioning of supersonic pulsing detonation straight-jet engines, mainly when flying at Mach number above 6. The method of functioning of the supersonic pulsing detonation straight-jet engine according to which the fuel is supplied to the main supersonic combustion chamber where the pulsing process is performed, for this purpose an antechamber is used which is installed upstream the main supersonic camera. A part of fuel is supplied into the antechamber, a pulsing flow is obtained and superimposed on a flow in the main supersonic combustion chamber. The antechamber is designed as a valve chamber with a constant fuel combustion volume the number of working cavities of which is selected according to the required frequency of pulsations in the main supersonic combustion chamber. The flow from the antechamber is divided and sent to the main supersonic chamber in the axial and radial directions.

EFFECT: invention provides stable burning in a supersonic flow of the aviation fuel - kerosene - without oxidising gas, without air pre-heating.
