针对某型导弹的实际飞行结果 ,在建立了合理的发动机推力模型及喷流模型的基础上 ,采用多学科的一体化仿真方法 ,重点研究了发动机喷流干扰对该型导弹飞行性能的影响。结果表明发动机喷流与发动机推力偏心及偏斜的共同作用将对飞行器飞行姿态和弹道产生显著影响 ,在飞行控制系统的仿真研究与参数整定中应综合考虑这些因素
Based on the actual flight results of a certain type of missile, a reasonable multi-disciplinary integrated simulation method is established based on the reasonable engine thrust model and jet model, and the influence of jet interference on the flight performance of the missile is studied emphatically. The results show that the combined effect of engine jet and engine thrust eccentricity and deflection will have a significant effect on flight attitude and trajectory of the aircraft. These factors should be considered in the simulation and parameter tuning of the flight control system
