摘要
研究潜艇在应急操纵过程中的姿态变化规律,在舱室破损情况下的供气挽回操纵的方法,采用可压缩气体的一维定常绝热摩擦管流理论建立了高压气吹除主压载水舱模型,并与潜艇大攻角运动数学模型结合,构建了潜艇应急操纵数学模型。对潜艇首部舱室破损时的挽回操纵过程进行了预报,使用车、舵、气动力抗沉的操纵模型进行仿真。仿真结果表明,建立的模型能够可靠地预报破损潜艇在应急浮起过程中的运动规律以及姿态变化,所采取的供气措施对实艇高压气的定量优化具有一定的参考价值。
In order to master the submarine＇ s pose variational rules in the process of emergency maneuver,the paper studied the gas-blowing recovery measures for answering the brokenness of cabin,and the model of compressed air blowing ballast tanks was established based on one dimensional and adiabatic frictional steady pipe flow theory.By fusing the blowing model and submarine motion with high angles of attack,this investigation derived the emergency maneuvering motion model and predicted the recovery maneuvering process of fore cabins flooded submarine,afterwards investigated the maneuvering measures for dynamic anti-sinking using impetus,rudders and compressed air. The simulation results indicate that the emergency maneuvering motion model provides reliable motion rules and variational pose of emergency up-floating damaged submarine,and the gas blowing measures are valuable for investigating the quantificational use of compressed air of actual submarines.
