摘要

水下航行器在超空泡状态直航时，其运动模式和常规全沾湿水下航行器完全不同，为保证该模式下直航弹道的稳定性，提出对超空泡航行器的纵平面、水平面和横滚三通道进行特殊控制。从超空泡航行器流体动力产生的机理出发，分析了其力学特性，建立了航行器三通道空间运动模型；采用空化器首舵和航行器尾舵对超空泡航行器直航弹道进行控制，利用极限操舵的控制模式降低了三通道之间的耦合。针对超空泡航行器直航三通道进行了动态特性仿真，仿真结果表明弹道航向稳定、深度偏差小、横滚振荡幅度可控

Abstract

When an underwater vehicle runs supercavitated in rectilinear motion, its motion characteristics are different from those of a usual fully wetted vehicle. In order to keep the trajectory stability, the special control is adopted for three-channel control about vertical plane、horizontal plane and roll of supercavitating vehicle. This paper analyzed the hydrodynamic characteristics of supercavitating vehicle based on the hydrodynamic mechanism, and established a three-channel space motion model. A control measure of three-channel of rectilinear motion trajectory adopting the bow rudder of cavitator and the tail rudder of vehicle was put forward, and the coupling of three-channel was reduced by using the “bang-bang” rudder operating. The dynamic characteristics of three-channel trajectory were simulated, analysis results show that the course of trajectory was stability; the deviation of depth was small and the oscillation range of roll was controllable
