仿蝠鲼水下航行器前置推进器的布局优化
Forward propeller layout optimization for a Manta ray-inspired UUV
摘要
Abstract
This study introduces a front-mounted thruster as an auxiliary propulsion mechanism,multiple front thruster configurations were designed and systematically analyzed to evaluate their impact on the vehicle's propulsion performance.A propeller body-force method combined with an overset grid approach was employed to perform two-degree-of-freedom self-propulsion simulations of the vehicle equipped with these thrusters.Based on this,a comprehensive investigation was conducted into the effects of thruster installation position and angle on the vehicle's hydrodynamic performance.The analysis encompassed the entire operational process from start-up acceleration to steady cruising,focusing on velocity,lift coefficient,drag coefficient,lift-to-drag ratio,and pitching moment coefficient,as well as flow field,pressure distribution,and vortex structures during steady-state operation.The results demonstrate that optimizing the placement and orientation of front thrusters can significantly improve the vehicle's sailing efficiency.Notably,adjusting the thruster installation angle effectively enhances the lift-to-drag ratio and stability of the underwater vehicle..关键词
