To study the effects of variable nozzle control laws on turbofan engine acceleration and stability, a model was presented to simulate the acceleration dynamic performance of turbofan engine with variable area nozzle. Based on different nozzle control laws, the engine acceleration and stability were computed and analyzed. It was found that the dynamic model can be used not only to predict of acceleration and stability of turbofan engine with variable area nozzle in accelerating, but also to optimize the design of the nozzle control laws.
