METHOD OF AUGMENTING LIQUID-PROPELLANT ROCKET ENGINE THRUST AND LIQUID-PROPELLANT ROCKET ENGINE Russian patent published in 2012 - IPC F02K9/56 

FIELD: engines and pumps.

SUBSTANCE: proposed method comprises using gas turbine driven by vapor of one of fuel components generated in combustion chamber cooling loop and consists in increasing gas temperature upstream of turbine. Note here that proportioned amount of another fuel component is injected into vapor flow for mix produced to be fired. Proposed engine comprises combustion chamber with cooling circuit and injector head, fuel and oxidiser pumps, and turbine with its inlet communicated with combustion chamber cooling circuit. In compliance with this invention, device made up of diffuser and injector are arranged in pipeline communicating chamber cooling circuit and turbine. Besides, said device includes igniter and flame stabiliser.

EFFECT: expanded operating performances.
