ADN基液体空间发动机的实验研究与在轨验证
Experimental investigation and on-orbit flying validation of an ADN-based liquid space engine
摘要
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 pa-per.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 (TD-LAS).The variation of characteristic parameters such as fuel gas temperature and component concentra-tions 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 per-formance 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.关键词
