Liquid fuel rocket engine.

摘要

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 within 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. An expansion nozzle cooling jacket means is arranged around the circumference of a high expansion nozzle. 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 for driving the booster means. The remaining major part of gasified fuel from the combustor cooling jacket means is fed directely into the combustor means, so that it may be combusted to be discharged as propulsive force so pressure loss of the gasified fuel is held to a minimum, while establishing a potential energy made available for driving the booster means.
