潜艇尾升降舵卡住时高压气使用需求研究

Disquisition on the Necessity of High-pressure Gas in Case of Blockage of a Submarine's Stern-rudder

对潜艇不同航速下和尾升降舵卡不同角度值的挽回操纵进行了仿真实验,分析了各挽回措施对纵倾和深度的控制效果,通过比较,得出了各航速下必须使用高压气才能成功挽回的尾舵卡情况,绘制了"舵卡挽回操纵高压气使用需求图"供实际操艇时参考使用.根据仿真结果和实际操艇经验,提出了避免出现危险舵卡事故的安全航行操艇建议.

A mass of simulation experiments on redeeming maneuver in different stern-rudder blocking instances are put up,and each redeeming measure＇s controlled effect on the pitch and depth are analysed.By comparing and analyzing the simulation results,the stern-rudder blocking instance in which the high-pressure gas must be released to ballast tank is pointed out,and the＂demanding diagram of high-pressure gas when satern-rudder blocking＂ is given.On the basis of practical navigation experience and simulation results,safety control advice was put forward in order to avoid the occurrence of dangerous rudder blocking accident.
