作者们提出了一种用于旋流氧化剂流型混合火箭发动机的液氧汽化喷嘴,以提高发动机性能。在这项研究中,我们为这种推力为1500牛的混合火箭发动机开发了液氧汽化喷嘴。利用一个与发动机的气态氧供应系统独立的喷嘴液氧供应系统进行了汽化实验。在设计点的小氧气质量流量和低燃烧压力下的测试运行表明,液氧可以通过喷嘴安全地汽化。证实了液氧汽化喷嘴的设计是合理的。使用通过液氧汽化喷嘴汽化的氧气进行的汽化和燃烧实验表明,实现了可靠且快速的点火以及无燃烧振荡的稳定燃烧。液氧汽化喷嘴提高了旋流氧化剂流型混合火箭发动机的发动机性能。
The authors have proposed a LOX vaporization nozzle for swirling-oxidizer-flow-type hybrid rocket engines to increase engine performance. In this study, we developed the LOX vaporization nozzle for this type of a hybrid rocket engine with a 1500 N-thrust. Vaporization experiments, using a LOX supply system for the nozzle to be independent of a GOX supply system for the engine, were conducted. The test runs at little oxygen mass flow rates and low combustion pressures at the design point showed that LOX could be vaporized safely through the nozzle. It was confirmed that the design of the LOX vaporization nozzle was proper. Vaporization and burning experiments using vaporized O2 through the LOX vaporization nozzle showed that reliable and rapid ignition and stable combustion without combustion oscillation were achieved. The LOX vaporization nozzle increased the engine performance of the swirling-oxidizerflow-type hybrid rocket engine.
