FIELD: engines and pumps.
SUBSTANCE: proposed method consists in feeding non-self-priming components into combustion chamber via tangential oxidiser feed channels and fuel spray nozzles, producing swirled gaseous oxidiser flow and fuel spray cone with subsequent mix formation and feeding fuel mix into combustion chamber. Said mix is ignited and fired in combustion chamber. Note here that one oxidiser jets from tangential fuel feed channels, prior to transforming them to swirled flow, run into fuel jets, while other oxidiser jets eject fuel mix into combustion chamber from paraxial zone. Then mix is ignited and combustion products are fed into chamber at supersonic speed and then with operating pressure reached therein, combustion chamber is blown down by gaseous oxidiser from swirled flow periphery to paraxial zone, while tangential and toroidal vortices of mix formation and combustion products are formed.
EFFECT: higher specific thrust pulse and longer life.
