Abstract
The invention discloses a kind of passive protection methods of submarine, include the following steps：Liquid injection apparatus is set in submarine front end, ejects liquefied gas；With the movement of submarine, liquefied gas package submarine whole body is ejected；Liquefied gas meets water, and temperature rises sharply gasification, wraps submarine, formation Bubble Heavy Curtain.When submarine is attacked by weapons such as enemy's depth charge, torpedoes, in submarine front end, setting liquid injection apparatus ejects liquefied gas, and heat gasification wraps submarine, forms Bubble Heavy Curtain.The method of the present invention is simple and effective, and the air curtain of generation can greatly reduce the damage that the weapons such as enemy's depth charge, torpedo explode to submarine.
Description
Technical field
The invention belongs to submarine safety protection technology fields, especially in the protection side that submarine is impacted by underwater explosion
Method.
Background technology
In common underwater demolition engineering, a set of bubble hair is set close to the bottom in quick-fried source between quick-fried source and protected object
Injection device generally uses the foraminate steel pipe of both sides Drilling.After toward input compressed air in emitter, just connect from aperture
Continuous constantly to launch a large amount of tiny bubbles, due to the effect of buoyancy, bubble population is from the bottom to surface motions, to form one
Road " Bubble Heavy Curtain ".
In submarine by when attacking of weapons such as depth charge, the torpedoes of enemy, manufacturing similar " Bubble Heavy Curtain " reduces
Shock wave damage is a kind of attemptable safeguard measure suffered by submarine.Specifically in implementation process, since submarine is in fortune
Dynamic state, how to obtain the Bubble Heavy Curtain of package submarine becomes problem.
Invention content
Present invention aims at provide a kind of method carrying out passive protection to submarine.
Technical solution is used by realizing the object of the invention：
A kind of passive protection method of submarine, includes the following steps：
Liquid injection apparatus is set in submarine front end, ejects liquefied gas；
With the movement of submarine, the liquefied gas ejected wraps up submarine whole body；
Liquefied gas meets water, and temperature rises sharply gasification, wraps submarine, formation Bubble Heavy Curtain.
By said program, the liquefied gas is liquid nitrogen air-liquid carbon dioxide or liquefied air.
When enemy attacks submarine using weapons such as depth charge, torpedoes, the shock wave for generation of exploding enters to inject
Water is contacted with air wall, since the compressibility of gas makes the part kinetic energy Transient transformation of shock wave be in compressed bubble
Can, bubble inner pressure power increases suddenly；After shock wave wave head, when wave rear pressure drops below pressure in bubbles, water and bubble
The potential energy stored in two-phase layer releases energy again such as shot bubble fluctuation pressure, to make through water and bubble two-phase layer
Shock wave pressure peak value afterwards reduces, and then plays a protective role to the submarine after Bubble Heavy Curtain.Good Bubble Heavy Curtain protection,
Water shooting generates shock wave pressure 90% or more can be cut down.
Beneficial effects of the present invention：When submarine is attacked by weapons such as enemy's depth charge, torpedoes, in submarine front end
Setting liquid injection apparatus ejects liquefied gas, and heat gasification wraps submarine, forms Bubble Heavy Curtain.The method of the present invention is simple
Effectively, the air curtain of generation can greatly reduce the damage that the weapons such as enemy's depth charge, torpedo explode to submarine.
Specific implementation mode
The technical solution that following embodiment further illustrates the present invention, but not as limiting the scope of the invention.
Liquid injection apparatus is installed in submarine front end, is attacked by weapons such as enemy's depth charge, torpedoes in submarine
When, eject liquefied gas；With the movement of submarine, the liquefied gas ejected wraps up submarine whole body；Liquefied gas meets water, and temperature rises sharply
Gasification wraps submarine, forms Bubble Heavy Curtain.It can react with seawater generates bulk gas, wraps submarine.Its
In, the liquefied gas is liquid nitrogen air-liquid carbon dioxide or liquefied air.
The device that the present invention can need is simple and effective, and the air curtain of generation can greatly reduce enemy's depth charge, torpedo
The damage that equal weapons explode to submarine.Good Bubble Heavy Curtain protection, can cut down water shooting and generate shock wave pressure
90% or more.
