潜艇舱室进水时应急挽回过程中的横摇运动

Rolling motion in emergency recovery maneuver in time of flooding submarine compartment

通过分析潜艇应急操纵情况下的横摇运动方程,提出了影响潜艇横倾变化的因素。然后,对不同事故状态下的舱室进水事故进行了数值仿真,确定采取不同挽回措施时潜艇运动状态的变化规律,验证潜艇状态参数对潜艇横倾变化的影响规律,并提出了减小应急上浮过程中横倾威胁的方法,以防止潜艇应急挽回过程中出现横摇、"枯叶"上浮现象。

Through analyzing the rolling motion equation under conditions of submarine emergency recovery maneuvering,this paper put forward the factors which affecting the roll.Then,the numerical simulation analysis of different accidents were conducted thus to obtain the motion regularity and characteristics of submarine emergency recovery maneuvering as far as the flooded compartment was concerned.And the influence of submarine state parameters on the change of roll was confirmed.Finally,this paper proposed the methods of reducing roll and the measures of preventing rolling motion and ＂adrift-leaf＂ during the period of submarine emergency recovery.
