REALIZATION METHOD OF ROCKET POWER AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC F02K9/42 

FIELD: aviation, astronautic science.

SUBSTANCE: invention can be used for launching the rocket stages separating parts after switching off the sustainer liquid propellant engine (LPE). The method is based on injection into the combustion chamber of the gasified liquid propellant components (PC), by stopping the sustainer LPE, including PC gasification systems, based on the pressurization gas supply to spherical tanks with additional PC, and by oxidizing or reducing gas generator, depending on the particular fuel in the tanks, supply of coolant into the tanks with the PC remains. The fuel and oxidizer feed line into the tanks from the shut-off valves is to be blown-down after stopping the sustainer LPE, the gasification products from each tank are supplied into the combustion chamber of sustainer LPE. The device for implementing the power of the liquid propellant engine includes the system of control and guidance and gasification system, located behind the shut-off valves, in the main fuel lines of the oxidizer and fuel there are spherical tanks for blowing-down the lines and extra feed lines, supplying the gasified fuel mixture, connecting the oxidizer and fuel tanks with the main LPE to bypass the turbopump unit.

EFFECT: LPE energy efficiency increase by means of energy resources implementation.
