摘　　要：水下航行体在空泡的包裹下运行,能够减小阻力从而提高速度。在运行过程中航行体的尾部会与空泡壁碰撞产生滑行力。由于空泡具有时滞效应,影响航行体尾部滑行力的计算。针对空泡的时滞效应,对比研究了时滞特性对超空泡航行体控制性能的影响。结果表明,时滞在定性上对性能不会引起质的变化,系统设计时可采用没有时滞的滑行力模型以简化计算,设计后再用时滞模型来进行仿真验证。The underwater vehicles traveling inside a cavity, enable to reduce the drag and increase the speed. In the course of operation, the tail of vehicle into contact with the cavity, as a result there is also a planing force acting back on the tail. The time delay effect of the cavity may affect the calculation of the planing force. It is compared in the paper the impact of the delay on the steady-state performance of supercavitating vehicles. And the result show that the time delay cannot change qualitatively the performance of supercavitating vehicles, and the time-delay model of the planing force can be used to simplify the calculation, and the time-delay model can be used for simulation and verification.
