METHOD AND DEVICE FOR ROCKET ENGINE POWER SUPPLY Russian patent published in 2018 - IPC F02K9/48 

FIELD: engines and pumps.

SUBSTANCE: invention relates to a device for feeding the chambers of rocket engines (100) with the first and second propellant components. The first power supply circuit (16) of the thrust-generating chamber (10) includes a turbo pump (22) having at least one pump (22a) for pumping the first propellant component from a first tank (12) and a turbine (22b) mechanically connected to said pump (22a). The first power circuit connects the pump output to turbine input through a heat exchanger (24) configured for heating the first rocket fuel component by heat created by thrust-generating chamber in order to operate the turbine. In accordance with the present invention, the second power supply circuit (18) is arranged to supply the second propellant component creating the thrust chamber by the second propellant component from the second tank (14) which is configured to maintain high pressure. The present invention also provides a method for feeding the thrust-generating chamber of the rocket engine chamber with the first and second propellant components.

EFFECT: increased pressure in tanks containing rocket fuel components.
