PULSEJET CUMULATIVE ENGINE Russian patent published in 2019 - IPC F02K7/02 F02K9/42 

FIELD: engines and pumps.

SUBSTANCE: pulsejet cumulative engine comprises a combustion chamber, a nozzle unit, an oxygen supply channel and a hydrogen supply channel, an oxygen distribution chamber, a hydrogen distribution chamber, a swirl chamber of oxygen, a hydrogen swirling chamber. Oxygen from swirling chamber of oxygen is supplied to combustion chamber along conical channel that connects swirling chamber of oxygen and combustion chamber. Hydrogen from hydrogen vortex swirling chamber enters combustion chamber along its conical channel that connects hydrogen swirling chamber and combustion chamber. When the flow of oxygen and flow of hydrogen enters the combustion chamber, oxygen and hydrogen are mixed to form a combustible mixture which, in a spiral, fills the combustion chamber, thereby forming a funnel; the funnel axis of symmetry coincides with the axis of symmetry of the combustion chamber. In bottom of combustion chamber there is an ignition chamber, in which conditions are created for occurrence of detonation wave at ignition of combustible mixture from ignition plug.

EFFECT: invention is aimed at simplifying the design and increasing specific impulse.
