ABSTRACT:
The present invention is related to a liquid fuel rocket engine of the type that a liquid fuel is boosted in pressure by way of a booster means. Thus boosted liquid fuel is gasified with a fuel cooling jacket of a fuel combustor means with an expansion pressure of thus gasified fuel being adapted to energize the booster means, and the gasified fuel is sent to the fuel combustor means so as to be combusted therein to produce a combustion gas to be discharged outwardly serving as a propulsive effort of the rocket engine, wherein there is mounted an expansion nozzle cooling jacket means around the circumference of a high expansion nozzle means of the combustor means, wherein part of the gasified fuel from the combustor cooling jacket means is directed into the expansion nozzle cooling jacket means to be reheated therein resulting in an increased potential energy to be utilized as a potential energy for driving the booster means, and wherein the remaining major part of gasified fuel from the combustor cooling jacket means is fed intact into the combustor means, not utilized to energize the booster means, so that it may be combusted to be discharged as propulsive force, whereby a pressure loss of the gasified fuel is held to a minimum, while establishing a potential energy made available for driving the booster means.
