摘要

摘要: 针对超空泡航行器航向舵后置布局在强机动航行时舵效不足的问题, 建立了一种全新的兼顾直航与机动运动的控制面布局模式, 首次提出了非对称分布艏舵的超空泡航行器控制面总体方案, 采用双自由度空化器作为控制面, 水平偏转控制航向, 上下偏转控制俯仰和深度, 且在空化器下部复合抗横滚鳍片。针对某超空泡水下航行器进行了系统动态特性仿真分析, 横滚剩余力矩约从0.1s衰减至0, 极限横滚角小于0.1°。分析结果表明: 以空化器作为艏部航行舵替代常规布局的尾部航向舵, 可以显著提高舵效。

Abstract: A novel hydrodynamic layout based on anisomerous bow rudder was firstly proposed for strongly maneuvering underwater supercavitating vehicle because aft rudder is short of effectiveness.In the layout, straight-and-level flight and strong maneuverability motion were considered.Bow rudder with 2 DOFs controlled orientation with deflexion in level, and controlled pitching or depth with up-and-down motion.Anti-roll fin appended below the rudder generated imbalances torque.For validating the dynamic characteristic of the design layout, related simulation on a supercavitating vehicle was carried out.The attenuation of remanent roll moment completes in about 0.1 s, and ultimate roll angle is less than 0.1°.Analytical result shows that the novel layout can markedly improve control rudder effectiveness.
