构建了深潜救生艇对接潜艇的计算流体力学(CFD)模型,量化了海流对深潜救生艇大倾角条件对接作业的影响,在此基础上,通过研究深潜救生艇操艇系统的操控能力,建立了主辅推进器的推力模型,结合推进器对接作业时的使用策略和CFD数值计算结果,给出优化对接作业的操纵方法。研究结论可为操纵员在受流影响下进行大倾角对接作业提供优化依据,提升援潜救生作业的安全性和有效性。

This paper constructs a computational fluid dynamics(CFD)model for the docking operation of a deep submergence rescue vehicle(DSRV),and quantifies the influence of ocean current on the operation at a high inclination angle.On this basis,through the analysis of the control ability of DSRV handling system,a thrust model of main and auxiliary propellers is set up,and then the docking method is optimized in combination with the actual docking strategy and the CFD numerical calculation result.The research conclusion provides a basis for DSRV operators to conduct docking operation at a high inclination angle under the influence of current,and improves the safety and effectiveness of submarine rescue docking operation.
