潜艇动力抗沉运动特性分析

采用潜艇垂直面操纵性运动方程、破损舱进水方程和压载水舱排水方程联立构成的潜艇动力抗沉运动方程,研究了2艘不同吨位潜艇的损管特性和动力抗沉运动,其中动力抗沉运动计算包括单独高压气吹除和高压气吹除加操上浮舵2种情况,并讨论了单独高压气吹除、高压气吹除与操舵联合作用的抗沉效能,从而明确了操舵在动力抗沉中的作用。通过对两艇的仿真计算结果的讨论与分析,并用动力不沉性指数Ka定量地评估了转舵在潜艇动力抗沉中的作用。计算结果表明,潜艇中、首部隔舱破损时,转舵在动力抗沉中效能显著,尾部隔舱破损时效能不明显,甚至作用相反。

Submarine's dynamic anti-sinking motion capability

By using the standard maneuverability motion equation, ballast inundation equation and compressed air blowing damage water equation as simultaneous equations, the damage control capabi-lity and dynamic anti-sinking motion of two submarines of different tonnage were calculated, and two cases with only high pressure air blowing and high pressure air blowing adding to uplifted steering were included in dynamic anti-sinking motion calculation. The anti-sinking capacity was analyzed and the effect of steering in dynamic anti-sinking was defined and evaluated according to anti-sinking index and simulation. The analysis results show that in the submarine when amidships and forward cabins are damaged, the performance of steering is significant in dynamic anti-sinking, yet the effectiveness is not so evident when it is in the stern, even producing opposite operation.
