摘　　要：针对超空泡航行体的弹道及操纵特性进行研究,建立了超空泡航行体在纵平面内的简化运动方程,编制了相应的弹道仿真程序,并对其在90 m/s左右速度区段内的典型弹道特性进行了仿真分析.仿真结果表明,通过对雷顶舵进行典型操舵控制,超空泡航行体可以在无反馈控制的情况下,实现定深直航,以及变航向、变深度等典型弹道机动,可见超空泡航行体的操纵特性良好.An improved control and guidance system for supercavitating vehicles was designed. Simplified equations for longitudinal motion of supercavitating vehicles were derived and corresponding software for simulating the trajec- tory of supercavitating vehicles was written using the typical trajectory characteristics of supercavitating vehicles that roof rudder in the absence of feedback control. This proves that the maneuverability of supercavitating vehicles is good.
