摘　　要：超空泡技术可以大幅减小水下鱼雷的阻力,提高水下武器的速度及战斗力,因为空泡的包裹使得水下超空泡鱼雷的流体动力问题极其复杂,分析了水下高速超空泡鱼雷纵向平面上空化器、尾翼控制面的动力及其尾部滑行力。根据纵平面基本动力学方程,给出了超空泡鱼雷纵平面的非线性基本动力学模型,并计算了模型的具体参数。在纵向平面上,超空泡鱼雷的运动方程是一个具有动态耦合的弱阻尼系统。仿真分析了超空泡鱼雷纵向运动和稳定性。Supercavitation technology can significantly reduce skin-friction drag of underwater torpedo, and therefore dramatically increase the velocity and attack power of underwater weapons. Because the torpedo is almost entirely enveloped by a supercavity, the hydrodynamic problems of the high-speed supercavitating torpedo （HSST） are complex. The hydrodynamic forces acting on cavitator, fin, and the planing force along the longitude plane of the underwater HSST are analyzed. A benchmark nonlinear dynamics model of supercavitating torpedo is established based on the basic dynamic equations of the longitude plane, and the specific parameters of HSST are calculated. In the longitude plane the motion equation of HSST is a four-order dynamic coupled system with lightly-damped characteristics. Stability and the longitudinal motions of HSST are analyzed by the simulation.
