摘要
针对Aster导弹在PIF(pilotage inertial enforce)-PAF(puissance an frein)控制中的动力学问题,分析了侧向推力对导弹法向力、俯仰力矩、控制力的影响,建立了PIF-PAF控制导弹的纵向运动模型,采用小扰动线性化方法得到了PIF-PAF控制导弹的纵向扰动运动模型以及短周期运动模型。探讨了PIF-PAF控制提升过载响应时间的原理。解释了Aster导弹采用大面积弹翼、大面积舵面并将弹翼前缘后掠角设计为零的原因。
Dynamic problems of air defense missiles with the pilotage inertial enforce-puissance au- frein (PIF-PAF) control are studied. The effects caused by lateral-jet on normal force, pitching moment and aerodynamic control force are analyzed. The dynamic model of PIF-PAF control missile is estab- lished. The linear approximations are employed to build a state equation model and a short term response model of the overload. Based on the models, mechanism of PIF-PAF control to raise the maneuver capa- bility of missile is studied, the reasons why Aster missile adopts large rudders and large wings with zero degree sweep angle are explained.
