Based on the characteristics of each component of the engine, the numerical analysis of the accelerating process of a biaxial engine was carried out by using the method of changing the specific heat capacity of flow parameters. A two-layer iterative method is developed to simulate the effect of variable nozzle throat area on engine acceleration. The variable nozzle adjustment scheme is proposed to improve engine acceleration.
