    • PROBLEM TO BE SOLVED: To provide a heat exchange injector assembly 22 for a rocket engine promoting gasification of an oxidizer even under a condition of relatively low propellant flows. SOLUTION: The heat exchange injector assembly 22 of the invention includes a plurality of heat exchange elements 58 each of which comprises a fuel sleeve 70, a liquid oxidizer post 72 disposed in the fuel sleeve 70 and a multi-passage swirl member, for instance a double helix member 74, disposed in the liquid oxidizer post 72. The oxidizer is divided into two flows by the double helix member 74 to exchanges heat with high temperature fuel and is mostly gasified even at a low thrust level so that a pressure difference between the heat exchange injector assembly 22 and combustion chambers downstream thereof can be sufficiently ensured.

    • 要解决的问题:为了提供即使在相对低的推进剂流动的条件下也能促进氧化剂气化的火箭发动机的热交换喷射器组件22。 解决方案:本发明的热交换喷射器组件22包括多个热交换元件58,每个热交换元件58包括燃料套筒70,设置在燃料套筒70中的液体氧化器柱72和多通道旋流部件, 例如设置在液体氧化器柱72中的双螺旋构件74.氧化剂被双螺旋构件74分成两个流,以与高温燃料进行热交换,并且即使在低推力水平下也大部分气化, 可以充分确保热交换喷射器组件22与其下游的燃烧室之间的差异。 版权所有(C)2008,JPO&INPIT
