ROCKET POWER PLANT WITH NON-SENSITIVE ARMING AND MULTIPLE OPERATING MODES, AND ITS OPERATING METHOD Russian patent published in 2012 - IPC F02K7/18 F02K9/72 

FIELD: engines and pumps.

SUBSTANCE: rocket power plant includes liquid oxidiser and solid fuel in separate compartments, main nozzle, afterburner, liquid oxidiser injectors and air intake supplying the air to afterburner. The main nozzle is located downstream of solid fuel compartment and receives exit gas enriched with fuel after combustion of liquid oxidiser and solid fuel. Afterburner is located downstream of the main nozzle and has the inner part covered with rocket fuel rich in oxidiser. Liquid oxidiser injector located upstream includes the first valve supplying the liquid oxidiser to the end of solid fuel, which is located upstream. Liquid oxidiser injector located downstream includes the second valve acting irrespective of the first valve and supplying the liquid oxidiser before the main nozzle. At operation of the above power plant there mixed are combustion products of liquid oxidiser and solid fuel, which are rich in fuel, and solid rocket fuel rich in oxidiser for acceleration in afterburner, creation of draft and provision of translation movement as hybrid rocket engine.

EFFECT: inventions allow increasing the safety of rocket power plant.
