摘    要:为了进一步研究超高速航行器空化减阻问题,建立了空化状态下超高速水下航行器纵向运动数学模型,对该航行器在巡航段平衡状态下受扰动时的攻角和俯仰角速度的阶跃响应进行了分析,并通过根轨迹法分析了运动的稳定性。分析结果表明,通过给定平衡攻角和平衡舵角,航行器能够呈现一定的静稳定性,该特性有利于以直航弹道为主的超高速水下航行器保持超空泡稳定。

关 键 词:超高速水下航行器  纵向运动  阶跃响应  根轨迹法  稳定性

Abstract:In order to study cavitation drag reduction of a high speed underwater vehicle, we establish a longitudinal motion model of the vehicle in supercavitation condition, analyze the step responses of attack angle and pitch angular velocity of the vehicle under turbulence in the balance state of cruise phase, and also analyze the motion stability through the root locus method. The results show that the vehicle can exhibit static stabilization under given balanceable attack angle and rudder angle, which is beneficial to keeping stability of a high speed underwater vehicle with straight running trajectory.
Keywords:high speed underwater vehicle  longitudinal motion  step response  root locus  stability
