摘要：

The combustion instability phenomenon of a missile engine is analyzed by using the spectrum analysis of the pressure data and the acoustic mode analysis by the numerical simulation of the chamber. Two kinds of mechanisms of inducing nonlinear combustion instability are proposed. It is proved that the acceleration of the missile is the main cause of the engine combustion instability by comparing the results of the pulse-triggered test and the rocket sled test. © 2019, Editorial Dept. of JA.
