液体火箭发动机混合比故障检测

正常模型　变推力发动机其系统结构和数学模型的推导详见文献1]。在这里,我们主要是要研究如何根据系统仅能提供的燃烧室压力测量值检测混合比严重偏高的故障,所以略去其它部件(见图1)。 

MIXTURE RATIO FAILURE DETECTION FOR LIQUID PROPELLANT ROCKET ENGINE

The mixtare ratio failure detection for liquid propellant rocket engine has been studied by means of Kalman filtering and statistical hypotheses testing.A computer simulation of a variable thrust rocket engine demostrates that the algorithm developed by authors can effectively detect mixture ratio deviation.The simulation also gives some significant results useful for the practical application and the further research of the algorithm.
