Description
Technical field
The invention belongs to moving object high speed entry work fields, and in particular to a kind of reversed jet bubbling crystallzation assistance is high
Speed enters water and lowers shock loading mechanism.
Background technique
Movable body is during entering at a high speed water, since Media density mutates to generate excessively high shock loading, mistake
High impact loads will lead to the intracorporal instrument failure of movement, even result in the destruction of movable body structure.In order to avoid such case hair
It is raw, the water surface is squeezed by high-energy jet stream, gas cavity is formed during entering water and is wrapped in sail body surface, to reduce resistance
Power plays the role of buffering and being inducted into water.Vacuole technology in underwater drag reduction is exactly the coke of various countries' concern since the last century
Point, the especially appearance of " snowstorm " supercavitating torpedo, even more the excitation successive input research in various countries, recently as some bases
Research is enriched, and vacuole drag reduction technology is also widely applied therewith, is used not only in application of the underwater sailing body on water surface speedboat
Maturation all the more.It is direct " momentum-exchange " that vacuole technology successfully avoids water and sail body in high speed operation, by vacuole this
Layer " lubricating oil " has mitigated contradiction between the two.It is well known that the contention of maritime rights and interests is more nervous, it can in antisubmarine war
To use movable body to be hit, but whether in offshore defensive or long-range accurate abatement, the movement of high-speed flight in the sky
Body can undoubtedly encounter huge resistance when contacting the water surface, can not only make sail body deviate trajectory even directly fracture or
Explosion, therefore high-speed aircraft problem of water entry how is solved as domestic and international research hotspot.
It there are many thinking is slowed down by parachute before entering water in the past to solve contradiction between the two
Or install the measures such as protection additional, the prompt strike capabilities of movable body and the lethality to enemy can be inevitably reduced in this way, and are given
The chance that enemy's evacuation and counter are led, it is now necessary to propose that one kind preferably enters water mode.Worthington has studied at first
Movable body enters water phenomenon, observed sphere and enters the splash generated when water and vacuole.Thereafter researcher is mainly for aerial torpedo
Enter structure during water to destroy, trajectory unstability and the research into water is unfolded the problems such as ricochet.During usual movable body enters water,
The water extruding of interface is torn in front, and vacuole is opened in formation, and air enters in vacuole during this time, continues to transport downwards in model
During dynamic, air is also constantly involved in vacuole the development for maintaining vacuole.In further development, there is deep water closure, and
Movable body is completely wrapped up by vacuole under water.Such case is similar to the forming process of bubbling crystallzation in water, but due to boat
The quality of row body and the area of front contact water are larger, and it is fatal for entering the negative influence of water load.
Summary of the invention
That invents herein is designed to provide a kind of reversed jet bubbling crystallzation assistance for making sail body be not required to slow down into water
High speed enters water and lowers shock loading mechanism.
A kind of reversed jet bubbling crystallzation assists high speed to enter water to lower shock loading mechanism, including high pressure gas cylinder, gas circuit are whole
Stream cover, engine, jet pipe, empennage, stomata, high-speed gas jet hole, movable body, air cavity, electronic pressure regulating valve, electronic flowmeter,
Computer Control Unit, screw connection；Radome fairing is threadedly attached in movable body head, circumferentially equal on movable body head
Several stomatas of cloth, stomata are communicated with the annular air cavity of enclosure interior, and engine is supplied by gas circuit to air cavity, are disposed in gas circuit
Electronic pressure regulating valve and electronic flowmeter, air cavity connection are located at the high-speed gas jet hole at the top of movable body, and high pressure gas cylinder passes through cloth
The air circuit connection for being equipped with electronic pressure regulating valve and electronic flowmeter is located at high-speed gas jet hole at the top of movable body, and jet pipe is located at dress
The tail portion set.
The beneficial effects of the present invention are:
The present invention tears one of gap before movable body contacts the water surface by the air jet of high-energy, and is penetrated by air
Stream replaces movable body head to squeeze the water surface, and suitably supplements air on head, and formation is opened vacuole and stable supercavity, do not had
Significantly being slowed down to movable body, movable body prompt strike capabilities do not weaken, it more efficient can hit the mark, movable body
It does not need to slow down and just avoids the most load resistance in front, speed and the contradiction for entering both water resistances are readily solved；And
Resistance suffered by movable body is that continuous slowly variation is conducive to move there is no by unexpected step force in the present invention
The stability of body.
Detailed description of the invention
Fig. 1 is the schematic diagram of mechanism of the present invention；
Fig. 2 is that the present invention enters water process.
Specific embodiment
The present invention is described further with reference to the accompanying drawing.
It as shown in Fig. 1, is the schematic diagram of mechanism of the present invention；Including high pressure gas cylinder 1, gas circuit 2, radome fairing 3, engine 4,

As shown in Fig. 2, enter water process for the present invention；Movable body 9 emits from firing base, according to the trajectory of setting in sky
Middle flight is experienced when movement body sensor and closes on a certain height of the water surface, prepares to carry out second step into water；Movable body controls journey
Sequence is opened high pressure gas cylinder 1 and is supplied to high-speed gas jet hole, and there is a corresponding load cell on movable body head, control program according to
Calculation formula passes through flowmeter and pressure regulator valve appropriate adjustment tolerance flow velocity；Air jet squeezes the water surface and tears gap, and movable body is opened
Begin to gradually form the opening vacuole on covering movable body head into water；If can not be complete by movable body due to tolerance deficiency
Package can open the flow valve on control 7 this road of stomata, to opening vacuole ventilation make-up gas, ultimately form supercavity completion and subtract
Hinder purpose, movable body from air to water in do not carry out obviously slow down smoothly it is smooth be immersed in the water, rapidly hit enemy's mesh
