Abstract
To address the problem that self-propelled deployed unmanned undersea vehicle(UUV)are significantly disturbed by the wake field of the mother platform and deployment device during the two-body separation process,resulting in remarkable changes in maneuverability,based on the Reynolds average Navier-Stokes(RANS)method,this paper combined multi-reference frame(MRF)with the overset mesh technology to establish a numerical calculation method suitable for studying two-body separation.This paper further researched the hydrodynamic characteristics of a self-propelled deployed UUV.Multiple steady-state conditions were selected to compare and analyze the hydrodynamic characteristics of a typical rotary UUV in the deployment state and the free state.The research results show that under the wake field of the deployment device,the UUV is significantly disturbed,with position force coefficients including resistance coefficient,lift coefficient,and pitching moment coefficient changes ranging from 7.12%to 343.04%,rotational force coefficient changes ranging from 22.81%to 97.16%,and steering force coefficient changes ranging from 11.83%to 164.98%;the maneuverability of the UUV is significantly less than that in the free state.The research results of this paper can provide a certain theoretical basis for the optimization of the deployment scheme and the design of control strategies for self-propelled deployed UUVs.关键词
