脉冲爆震发动机点火起爆控制规律

Control law of the ignition of a pulse detonation engine

点火起爆过程对爆震波形成起关键作用。点火起爆过程和充填过程紧密相连,合理控制点火起爆是保证脉冲爆震发动机稳定工作的前提,研究中定义了点火起爆控制因素,给出了点火时刻估算方法,分析了点火延时和点火频率影响因素,在理论分析基础上给出脉冲爆震发动机点火起爆控制规律。

The ignition process is important in the detonation wave engine. The process of ignition is relevant to the filling and the detonation formation processes, The control factor of the ignition is defined and the method to calculate the ignition delay is given and the law of the ignition delay changing is analyzed. The effect factors of the ignition frequency is analyzed. On the basis of above analysis, the control law of ignition is acquired, which is the base of ignition control system design.
