摘要： 以液氮为模拟推进剂,含二氧化碳的氮气为增压气体,进行了液氧煤油火箭的液氧箱自生增压试验研究。通过改变增压气体中二氧化碳的含量,分别模拟了液氧加热气化增压输送和富氧燃气增压输送,同时进行了二氧化碳在液氮中的结晶小试验,通过试验,从原理上验证了含二氧化碳的氮气增压输送液氮方案是可行的,为进一步试验研究及系统设计提供了参考。

Abstract: A series of experiments were carried out to investigate cryogenic liquid transfer performance by self-pressurization method for liquid oxygen tank. The working fluid is nitrogen and the pressurizing gas is nitrogen including a small fraction of carbon dioxide, respectively. By varying the content of CO2 in the pressurizing gas, liquid oxygen gasifying pressurization mode and abundant oxygen pressurization mode are simulated. Besides, an experiment of CO2 crystallization in liquid nitrogen is also conducted. The experiments show that the modes of simulation test are feasible. The investigation provides a reference for further study.
