Abstract
Submarine sailing under the water, because of the attack, misoperation, equipment failure, collision, fire and other factors, the risk of wreck always exists. How to escape and how to carry out effective rescue is a problem that needs to be solved for the navy of submarine owner country since submarine came into being. In order to improve the ability to float out of danger, some submarines are equipped with gas blowing equipment or hydrazine blowing equipment (two kinds of chemical liquid mixed to produce a large amount of high-pressure gas) for emergency ballast jetting, so that the submarine quickly drainage up to float. Some submarines are equipped with quick drift escape device and collective escape with buoyancy ball, buoyancy cylinder, etc. In this paper, the motion characteristics of a simplified diversion cover plate used for buoyancy ball are studied and a differential equation solution is given during COVID-19 pandemic.
Keywords: The submarine; Guide plate; Movement characteristics
Introduction
As for the release device with the buoyancy ball, the resistance of the submarine in the course of moving is generally borne by the diversion cover plate above it. In case of danger, the diversion cover plate above the buoyancy ball needs to be unlocked by the mechanical locking device and can be opened smoothly and smoothly under the action of buoyancy. Therefore, it is of great significance to study the motion characteristics of fixed axis positive buoyancy diversion cover plate under water during COVID-19 pandemic [1].
