- 摘要:
- 二硝酰胺铵(ADN)是一种高能量密度、不含氯元素的绿色无毒无机盐类物质。它可以作为氧化剂,与甲醇、水混合后组成ADN基液体推进剂。ADN基液体推进剂作为一种高性能、绿色无毒、可存储的新型推进剂,可以提供相比于传统肼类推进剂更高的比冲性能,代表了空间化学推进技术的一个新的研究方向和发展趋势。主要介绍了北京控制工程研究所研制的ADN基液体空间发动机的实验研究和在轨飞行验证情况。首先,基于可调谐二极管红外吸收光谱(TDLAS)的测量方法,针对一台1 N推力的模型ADN基发动机进行了实验研究,获得了燃烧室内燃气温度、CO与N2O组分浓度等特征参数随喷注压力的变化关系。然后,介绍了0.2 N,1 N,5 N及20 N ADN基发动机的高空模拟热试车试验情况和主要性能指标。最后,介绍了1N ADN基发动机的首次在轨飞行验证情况。这些研究结果有利于绿色空间推进技术的发展。
- Abstract:
- The experimental investigation and on-orbit flying validation of the ADN-based liquid space engine developed by Beijing Institute of Control Engineering(BICE)are introduced in this paper.The experiment research about the combustion mechanism of the combustion chamber of a 1N model thruster was performed with the measuring method of tunable diode laser absorption spectroscopy(TDLAS).The variation of characteristic parameters such as fuel gas temperature and component concentrations of CO and N2O in the combustion chamber with injection pressure were measured.The effects of the propellant inlet pressure on the combustion process were evaluated.The hot fire test results and main performance indexes of an ADN-based liquid thruster family including 0.2 N, 1 N, 5 N, and 20 N thrusters are presented.The performance data at different operation conditions were obtained.The on-orbit flying validation result of the 1N ADN-based liquid thruster is introduced for the first time.The contents in this paper are beneficial to the development of green aerospace propulsion techniques.
