| 摘 要： | 为了研究某型采用格栅舵进行控制的巡飞导弹的纵向动态特性,分析了飞行时格栅舵偏转提供的控制力,采用小扰动线性化理论对气动力、气动力矩与运动方程进行了线性化,建立了纵向扰动运动方程组.选取巡飞初始状态为特征点,计算出该状态下各动力系数的值,由扰动运动方程组求得纵向自由扰动下各运动偏量的动态响应及以舵偏为输入的各偏量传递函数...

| Abstract: | To study the longitudinal dynamic characteristics of certain cruise missile controlled by grid fin,the aerodynamic force of grid fin was analyzed when the fin is steering in flight.The aerodynamic force equation,aerodynamic moment equation and motion equations were linearized based on the small-disturbance linearity theory,and the longitudinal disturbance equations were established.The beginning state of the cruise was chosen as the feature point,and then the values of dynamic coefficient were calculated.Th... |
