摘要
潜艇发生舵卡和舱室进水事故后,最有效的方法是通过吹除主压载水舱获取正浮力和校正力矩来挽回潜艇,高压气吹除主压载水舱模型建立的准确与否直接关系到潜艇挽回成功与否。因此,有必要开展高压气吹除主压载水舱模型研究。本文分析了潜艇高压气吹除主压载水舱物理模型特征,建立了高压气吹除主压载水舱短路吹除和常规吹除模型,并进行了仿真计算,为开展物理模型实验提供理论依据。结果表明,拉瓦尔喷管流量模型比较适用,压载水舱的排水量主要取决于高压气吹除率和高压气吹除使用方式,相同条件下某型潜艇高压气吹除系统短路吹除的排水量是常规吹除的2倍多。
When the accident of rudder-locked and flooded compartment happens to submarine,the most effective method to recovery submarine is acquiring positive buoyancy and moment through blowing main ballast tanks.The model of high pressure air blowing ballast tanks concerns the success or unsuccess of submarine＇s recovery,so it is necessary to carry through the research of high presure blowing model.The paper analyzes the characterstic of physical model of high pressure air blowing submarine＇s main ballast tanks.Then establish the short circuit and routine blowing model,and carry through simulation,which provide the theoretics foundation to carry out physical model experiments.The result indicate Laval model is feasible,and the tonnage of ballast tanks mostly rest with the application mode of high pressure air.The tonnage of short circuit is twice more than the routine blowing in coequal terms to a certain submarine.
