摘　　要：[目的]针对潜艇垂直面操舵潜浮机动模式中存在的低航速下艉升降舵变深能力差,以及艉升降舵卡舵和遭遇海水密度断崖时挽回困难的问题,开展静力矩操纵方式的机理性研究。[方法]首先,通过理论分析证明采用静力矩操纵方式可以消除艉升降舵的逆速现象;然后,对潜艇采用静力矩和舵水动力操纵方式实施上浮机动过程进行数值模拟。[结果]结果显示,采用静力矩操纵方式能使潜艇在低航速下保持良好的垂直面机动性能,消除艉升降舵的逆速现象,并可避免潜艇在高航速下产生过大的纵倾角;同时,还能改善卡舵和掉深这2种紧急情况下的挽回效果。[结论]采用静力矩操纵方式有利于提高潜艇的机动性和安全性,研究结果可为潜艇的操纵能力设计提供参考。[Objectives]Aiming at the problem of poor depth-changing ability of the stern rudder of submarine at low speed,and the problem of reversing the movement trend is difficult when the stern rudder is stuck and encountering abrupt changes of seawater density in the vertical steering maneuver.This paper conducts the mechanism research of static moment maneuver.[Methods]First,it is proved through theoretical analysis that the static moment maneuver can eliminate the reversed velocity phenomenon of the stern rudder.Then,the surfacing process under the static moment maneuver and the rudder hydrodynamic control is numerically simulated.[Results]The simulation results show that the static moment maneuver can make the submarine maintain good vertical plane maneuverability at low speed,eliminate the reversed velocity phenomenon of the stern rudder,and avoid excessive trim angle of the submarine at high speed.At the same time,the recovery effect of the two emergency situations of rudder jamming and falling deep has been improved.[Conclusions]The static moment maneuver is beneficial to the maneuverability and safety of the submarine.The research in this article can provide a reference for the maneuverability design of submarine.
