不同尾翼受发动机羽流作用对弹体飞行性能的影响

Effect of impact of engine plume to tails on missile flight performance

针对某型靶弹在试验飞行时采用不同尾翼布局所得的截然不同的飞行结果 ,开展了固体火箭发动机喷流干扰对飞行器飞行性能影响的研究。结果表明 ,发动机喷流与发动机推力偏心、偏斜的共同作用将对飞行器飞行姿态和弹道产生影响 ,且影响程度与飞行器尾翼布局有很大关系。

During flight test, different tail shapes for a target missile resulted in entirely different flight result, so a multidisciplinary integrated simulation environment was built to research the effect of solid rocket engine's plume on flight performance The results indicate that the engine plume combined with thrust eccentricity and deflexion have significant effects on aircraft's flight attitude and trajectory, and the effect degree is attributed to the aircraft's tail configuration
