摘　　要：针对潜艇高压气吹除压载水舱应急挽回姿态控制难题,以吹除高压气和压载水舱中压力气体为研究对象,推导并构建了高压气吹除和压载水舱解除气压数理模型。结合潜艇应急挽回数学模型,对潜艇发生破损进水事故的应急挽回过程进行数值仿真,分析了某潜艇事故采取3种不同挽回方案条件下潜艇运动姿态变化规律。研究结果表明:所构建的数理模型能较好描述潜艇应急挽回姿态变化规律,为潜艇应急挽回运动规律预报、潜艇运动状态实时评估和姿态控制方案制定提供理论依据和技术支持。Aiming at the problem of submarine motion posture during high-pressure blowing main ballast tank emergency recovery,the mathematical model of high-pressure gas blowing and pressure relief of ballast tank was deduced and constructed by taking blowing high-pressure air and pressure gas in ballast tank as the research object.Combined with the mathematical model of submarine emergency recovery established by the research group,the emergency recovery process of flooded submarine was numerically simulated,and the change law of submarine motion posture under three different emergency recovery plan was analyzed.It is concluded that the constructed mathematical model can better describe the posture change law,and thus provide theoretical basis and technical support for the prediction of submarine emergency recovery motion law,the real-time evaluation of submarine motion state and the formulation of posture control scheme.
