Abstract

The utility model relates to a modular type solid-liquid-explosion composite armor which is used and attached on a tank. Dynamic energy which is born by a pricking and bursting armor bullet can be transmitted to the circumference by pressure transmission liquid, which causes that when the dynamic energy reaches a main armour, the unit pressure is lowered to the minimum. When the pricking and bursting armor bullet punctures a solid-liquid composite armor box, firstly, the armour is hardened to reduce the speed by one layer of surface. Simultaneously, pressure transmission to the circumference can be carried out by the pressure transmission liquid. After penetrating a Kevlar corrugated plate, the pressure is embedded into a honeycomb plate and pressure transmission to the circumference is continued. Finally, the pressure penetrates the solid-liquid composite armor box to strike an explosion reaction armour and the solid-liquid composite armor box together with a bullet which comes to make an attack are thrown away from the main armour.

Description

Modularization is consolidated-liquid-quick-fried compound applique armour

The utility model relates to the box-packed liquid state of a kind of modular plate armour, and the composite armour of explosive reactive armor (ERA) box is particularly arranged with several layers of solid armour plate interlayer, box tail band in the armored cassette.

Modern main battle tank all generally adopts solid-state composite armour.It has metal and metal composite, metal and nonmetal compound, several forms such as spaced armor.In addition, also can adopt or install additional nonhomogeneous armors such as face-hardened armor, the worn-out plate armour of screen, reactive armor separately according to the compromised degree of tank all directions.Tank hull and the gun turret made with these armour materials are that tank is resisted the attack of various antitank weapons and the basis of tank battlefield viability.But the development of antitank weapon is in recent years particularly adopted the armor piercing fin stabilized discarding sabot projectile of uranium alloy and is with the high explosive anti-tank cartridge/antitank missile of the hollow charge warhead of depleted uranium cavity liner that existing composite armour has been constituted great threat.From present armor technology level, wear/break the protection level that the first ability is higher than at present existing composite armour for two kinds of above-mentioned two class ammunitions.Therefore, the body protection is undesirable, and gun turret, the irrational tank of the positive armoring inclination angle layout of car body are very easily punctured by above-mentioned two class ammunitions.

In order to address this problem, the tank of country between east and west has adopted diverse ways.AUS has adopted a kind of depleted uranium armor, and it is a kind of depleted uranium to be contained plate armour in armour steel.Its armoring density is about 2.5 times of steel, and by suitable heat treatment, intensity rises to original 5 times, thereby has advantages such as high rigidity, high strength and high heat resistance, is applied to the M1A1HA main battle tank.Russia has adopted a kind of electromagnetic armor, and it is to utilize means such as electromagnetic induction and timing means, in time detects speed, direction and the distance of attacking bullet and imports microprocessor system.When bullet flew to tank armor the place ahead certain distance, plate armour can initiatively discharge electric energy and change magnetic energy immediately into, forms one magnetic cup barrier bullet is destroyed.This plate armour is applied to Russian FST-2 main battle tank.In addition, Russia also develops the active guard system of a series of optical countermeasures, comprises ARENA (A Leina), SHTORA-1 (Shi Tuola), TSHUL-7 (Chu Er) etc.These initiatively guard systems promptly can detect the shell/guided missile that arrives and attack, and, can also the utmost point promptly start countermeasure system before they hit vehicle with its destruction.Though the depleted uranium armor that the U.S. adopts can effectively prevent unloading the high explosive anti-tank cartridge/antitank missile of the hollow charge warhead of present depleted uranium armor piercing shell and depleted uranium cavity liner, should the plate armour quality, density is big, can only be in the application of the key protection position of tank.Can Muscovite electromagnetic armor resist armor piercing fin stabilized discarding sabot projectile does not effectively still have example, and optical countermeasures initiatively guard system can not be defendd unguided armor piercing fin stabilized discarding sabot projectile effectively.In fact, the utilization of above-mentioned three kinds of safeguard procedures has caused the increase of tank gun bore, the increasing of gun pressure, and the thing followed will be the armor piercing fin stabilized discarding sabot projectile that quality is bigger, kinetic energy is higher, or even the strike of magnetic artillery.This point be present armor technology level can not defend.No matter be depleted uranium armor or electromagnetic armor, when being subjected to armor piercing fin stabilized discarding sabot projectile/high explosive anti-tank cartridge and hitting, its stress point is that bullet point or cumulative metal jet contact with car body or gun turret, thereby suffered unit pressure height, cracked can't the absorption in moment of the inner interlayer of its composite armour worn/all kinetic energy of high explosive anti-tank cartridge, so wear/high explosive anti-tank cartridge still has enough kinetic energy puncture tank master plate armours.

The purpose of this utility model provides a kind of brand-new modular solid-liquid-quick-fried composite armour, and it places on the main plate armour as a kind of applique armour, can defend the attack of armor-piercing bullet and high explosive anti-tank cartridge/antitank missile effectively.

Utility model is achieved in that divides two-layer arrangement two assembling decks in a thin-walled armored cassette.Top one deck is a face-hardened armor, is that one deck is thin armoring, below one deck be the cellular plate armour of hexagon, this plate armour is one deck heavy armor, the bottom is sealed by one deck thin-walled face-hardened armor.The armoring interlayer of the undulatory Kevlar of one deck is arranged between this two layers of armor.This interlayer is attached on the cellular board.Face-hardened armor and cellular board are flexibly connected by spring and armored cassette wall.Be full of antifreeze, fire-retardant pressure transmission liquid in the armored cassette, and can have kept internal hydraulic pressure a little more than external pressure.This armored cassette bottom has one deck rubber, is used for absorbing this superpressure, stop this armored cassette breakdown simultaneously after, one deck explosive reactive armor (ERA) below pressure transmission liquid flows into.It below this armored cassette an explosive reactive armor (ERA) box.When armor piercing fin stabilized discarding sabot projectile puncture solid-during liquid composite armour box, what at first hit is face-hardened armor.This plate armour back seat in breakdown passes to honeycomb plate armour and sidewall by pressure transmission liquid with the part energy.Contract is gone in the cellular board after armor-piercing bullet penetrates kevlar corrugated plate at a high speed, continue by pressure transmission liquid to around transmit kinetic energy.Behind armor-piercing bullet penetrates solid-liquid composite armour box bottom rubber, ignite the explosive reactive armor (ERA) this armored cassette under, with monoblock solid-liquid composite armour box casts main plate armour aside together with armor-piercing bullet.At this moment, the last kinetic energy of armor-piercing bullet is not enough to puncture main armoring.That high explosive anti-tank cartridge/antitank missile hits is solid-during liquid composite armour box, its kinetic energy easier by pressure transmission liquid to around transmit, the unit pressure that arrives on the main plate armour is lower.

The utility model is a kind of modularization applique armour, thereby the design that needn't change original tank, only need design armoring profile by the body of existing tank, so implement need not too expensive.The utility model utilizes liquid not to be compressed and the good characteristics of distinctive pressure transmission, be conceived to transmit, disperse and not only be to absorb suffered wearing/high explosive anti-tank cartridge kinetic energy, so load onto this armoring main battle tank worn/after high explosive anti-tank cartridge hits, main armoring pressure suffered on unit are is little, thereby is difficult for breakdown.In addition, owing to be the little pressure transmission liquid of proportion in the most space of this plate armour, so quality is little.Owing to be modular organization, can change a packaged first easily after hitting, thereby improve tank survival ability afield simultaneously.

The concrete structure of utility model is provided by the following drawings.

Fig. 1 is according to the schematic diagram that the utility model proposes.

Fig. 2 is the structure diagram of this utility model.

This device comprises a solid-liquid composite armour box 1 and 2 liang of most compositions of an explosive reactive armor (ERA) box.Gu be followed successively by face-hardened armor plate 3, kevlar corrugated plate 4, bottom in the-liquid composite armour box 1 from top to bottom by the cellular board 5 of face-hardened armor back cover with the rubber layer 6 at the bottom of being close to box.Face-hardened armor plate 3 and cellular board 5 are connected on the box wall of solid-liquid composite armour box 1 by high-strength spring 7.Antifreeze, the flame retardant type pressure transmission liquid 8 of no dissolved air have been sealed in the solid-liquid composite armour box 1.Explosive reactive armor (ERA) 2 places under solid-liquid composite armour box 1, leads on armoring 10.

Behind the upper wall of penetrating the armor piercing fin stabilized discarding sabot projectile puncture solid-liquid composite armour box 1 that comes along direction shown in the arrow 9, at first hit face-hardened armor plate 3, back seat when this armour plate is breakdown is transmitted suffered kinetic energy to triumphant cottonrose hibiscus corrugated plating 4, cellular board 5 by pressure transmission liquid 8 around reaching.Armor-piercing bullet moves on, because the cooperation of kevlar corrugated plate 4, make armor-piercing bullet very easily after puncturing kevlar corrugated plate 4 firmly contract go in the cellular board 5, while cellular board 5 back seats, continuation is with the whole lower wall transmission of kinetic energy to solid-liquid composite armour box 1, armor-piercing bullet continues to penetrate the rubber layer 6 of solid-liquid composite armour box 1 lower wall, hits explosive reactive armor (ERA) box 2, thereby will be whole solid-liquid composite armour box 1 is lifted off main plate armour.When the attack of anti-high explosive anti-tank cartridge of attacking along direction shown in the arrow 9 and antitank missile, each protecting component role and anti-armor-piercing bullet role are with preface, and be essentially identical.Around difference was that pressure transmission liquid 8 can be more effectively passes to the kinetic energy of suffered detonation wave, making it, final to arrive main armoring 10 unit pressure lower.
