摘要
潜艇在水下较高航速发生舱室进水或舵卡事故时,只能通过高压气吹除系统实施应急上浮进行挽回,而潜艇挽回成功与否主要取决于高压气吹除能力。为建立准确的高压气吹除系统高压气流量模型,本文在建立高压气吹除系统高压气流量数理模型的基础上,通过设计高压气吹除系统小比例实验装置进行高压气吹除的流动实验,分析影响高压气吹除流量的主要影响因素。对比实验结果和数理模型仿真结果表明,所建数理模型能较好描述高压气的流动过程,将吹除流量系数取0.7比较合理。
When submarine happen the accident of flooded compartment or blocked rudder under high speed,the only means of recovery submarine is to apply high pressure air blowing system making submarine emergency floating,then whether or not success of emergency recovery mainly lies on the ability of high pressure air blowing. In order to establish the accurate high pressure air flow model of high pressure blowing system,the paper carry out the high pressure air blowing experiment by designing the high pressure air blowing system experiment equipment under the base of high pressure blowing system flowing mathematical model. Then the paper analyzes the influence factors of high pressure air blowing flow,and compare to the experiment results and mathematical model simulation results. The results display that the mathematical model established can describe the flow process,and it is reasonable that define the blowing flow coefficient to 0. 7.
