可变载多轴矢量推进UUV水动力特性数值研究
Numerical Study on Hydrodynamic Characteristics of Variable-load Multi-axis Vector-propelled UUV
摘要
Abstract
Propulsion performance is one of the most important properties of underwater vehicles,and underwater vectored propulsion technology is the best choice for high-performance underwater vehicles in the future due to its all-round propulsion control capability,high propulsion efficiency,low vibration and noise levels.Considering the requirements of high-speed navigation and low-speed maneuvering,a"2+4"variable-load multi-axis vectored propulsion layout is proposed,which can achieve efficient propulsion at high speed and high maneuverability at low speed by changing the direction of thrusters.Based on computational fluid dynamics(CFD),the hydrodynamic characteristics of the unmanned underwater vehicle(UUV)equipped with this new propulsion layout under cruise and oblique navigation and the effect of thruster deflection on UUV hydrodynamic performance are studied.Our results indicate that there is a parabolic relationship between UUV resistance and the rotation speed of the thruster under high-speed cruise conditions.The oblique navigation and the deflection of the bow thruster have a significant effect on the vertical force and pitch moment of the whole UUV.The wake of front thrusters will weaken the performance of the rear thrusters.The retraction of rear thrusters has little effect on UUV hydrodynamic forces,but can provide additional control torques.The research of this work can provide an important reference for the optimal design of the propulsion mode and layout of high-performance underwater vehicles,and can be used as a guiding direction for the future improvement of the new UUV.关键词
