摘　　要：为开展自导超空泡航行体的研究,评估其最短自导作用距离尤为重要。本文在建立超空泡航行体动力学模型的基础上,计算出其基于主动倾斜转弯控制策略下的最大机动角速度为6°/s,并以此为基础研究了多种态势条件下的超空泡航行体追踪目标需用最短自导作用距离,分析了航行体初始段航向、初始相对距离等因素对需用自导距离的影响。仿真结果表明,弱机动条件下的超空泡航行体需要的自导作用距离均在1 km以上,以目前技术条件无法满足其导引需求,故在未来一段时间内,以超空泡鱼雷为代表的超空泡航行体武器仍应以直航攻击为主。In order to carry out the research of homing supercavitating vehicle, it is very essential to evaluate the necessary homing distance. With establishing the supercavitating vehicle dynamic model, this paper calculates the maximum maneuvering angular velocity to be 6/s based on the control strategy of active bank-to-turn, studies the necessary shortest homing distance under the various situations, and analyzes the initial course of navigation, the initial distance between vehicle and target, etc. The simulation results show that the necessary homing distance of supercavitating vehicle under weak maneuvering conditions is all above 1km, and the current technology cannot meet its homing requirements. Therefore, the supercavitating vehicle weapon represented by the supercavitating torpedo should still attack by direct route in the next period of time.
