Description
The cross reference of related application
The application requires to be filed in the U.S. Patent application No.11/713 on March 2nd, 2007,012 priority, this application is that the name of submission on September 15th, 2006 is called the U.S. Patent application No.11/521 of " Apparatus For Defeating HighEnergy Projectiles ", 307 continuation applies for that partly its content quotation is incorporated into this.
Technical field
The present invention relates to a kind of armor structure, the opposing of this structure is by penetrating that the high-energy solid projectile that is designed to defend vehicular armor causes.
Background technology
Conventional armor can stand the threat of various projectiles, these projectiles are designed to by armoring with solid or jet-like object penetration or by causing in plate armour to cause the shock wave that armoring cracked mode reflects to destroy plate armour, thereby formation opening, penetrant (adhere to usually armoring a part) passes, and perhaps Zhuan Jia internal layer is cracked opens and penetrated with high speed under the situation of physical penetration plate armour not.
Some antiarmor weapons are pushed and are incident upon armoring outer surface, thereby wherein the shaped charge blast forms the linear metal of cardinal principle " jet " that can penetrate the solid plate armour; These are commonly referred to hollow charge (HC) weapon.Second type antiarmor weapon uses the linear, heavy metal penetrator with projected at high velocity to penetrate plate armour.Such weapon is called as EFP (by the projectile of explosive stroke) or SFF (fragment certainly is shaped) or " cake formula explosive " or " board-like explosive " sometimes.
In wherein some of these weapons, bullet is the mixture of HC and EFP and produces a series of metal piercing things along the projection of straight line head for target.This weapon is called hybrid bullet here.Hybrid bullet according to its have how many " injection " or HC effects with and produce the EFP of how much independent one large-scale penetrator-like and the generation effect.
The kinds of protect system can defend the HC jet effectively.In different system, what be widely known by the people most is use explosive in protective layer reactive armoring, thereby blast interrupted most HC jet before it penetrates target when by bump.Problem is that these flare system not too are fit to defence EFP or hybrid system.
Proposed another system and defendd this weapon, wherein plate armour is made up of two-layer, and wherein electric conductor is arranged on therebetween.Between the adjacently situated surfaces of electric conductor and plate armour, produce tangible electromotive force.When jet or elongate solid penetrator penetrated plate armour, it produced conductive path between armor layer and electric conductor, and electromotive force passes this path and discharges.When enough electric energy of penetrator discharge were passed in existence, it was melted or evaporates, and it penetrates armoring ability of one deck down and obviously reduces.
The antiarmor weapon of another kind of type is to propel solid projectile (perhaps a series of multiple projectile) big relatively, heavy, that cardinal principle is spherical at a high speed.When spherical metal projectile bump was armoring, this bump caused shock wave, and this shock reflection makes that armoring plug shape part is sheared from material around and throwed along the path of metal projectile, and the metal projectile adheres to this.Armoring can the generation the personnel in system and the car significantly by this situation of destruction by this way very significantly damaged effect.
Make though design feature that the weapon of HC type adopts and material are represented the unit that they need have a professional technique, back one type weapon (EFP and mixture) can adopt the material manufacturing that obtains easily afield.Reason for this reason, the validity of this weapon is verified can to cause trouble to the vehicle that uses conventional armor.
Penetration performance for above-mentioned this bullet of three types is described to penetrate RHA (grinding the system homogeneous armor) the steel plate armour of certain amount of solid usually.Typical performance for this weapon type is: penetrable 1 to the 3 foot thick RHA of HC bullet, the RHA that the EFP bullet is penetrable 1 to 6 inch, penetrable 2 to the 12 inches thick RHA of hybrid bullet.These reckonings are based on the bullet of weight less than 15lbs, and bullet is in its best angle optimum stand off distances.Penetrate the hole that first inch RHA make diameter will for: HC can form the hole of an inch diameter, and EFP can form 9 inch diameter holes, and the hole that hybrid (Hybrid) forms is in therebetween.Best angle optimum stand off distances for different ammunitions is: for the projection distance of HC ammunition at 3 feet with interior good, at 10 feet or non-constant when farther; For the EFP ammunition, reach 30 feet projection distance and produce essentially identical (well) and penetrate and will only for example drop at 50 yards places in very large distance; Penetrating for hybrid bomb, is good at 10 feet projection distance places, but after 20 feet penetrated, beginning was obviously dropped.The mode that the employed mode of these ammunitions is optimized by these projection distances and their validity is determined (for example, arriving the angle of the track of armoring penetrator).These factors can influence the armoring design of protection.
The present invention can resist hybrid explosive effectively, thereby because its edge that must be arranged to close road forms dark penetrating, thereby so required part of its bump target that must be inclined upwardly.Therefore, it can be not clash into this plate armour perpendicular to its surperficial angle.Therefore, jet is at least in part from its track deflection and reduce it and penetrate.Effectively EFP can clash into and have good chance and penetrate from long relatively projection distance, but the present invention is very effective for opposing EFP.Hybrid and EFP is the threat that the present invention will handle.
Though any anti-armoring projectile can be had the adequate armour protection of sufficient intensity and thickness, but extra armor thickness is heavy and expensive, all can gain in weight to any armored vehicle that uses it, then vehicle motor and driving system be caused bigger distortion.
When penetrating required RHA when comparing, resist these type weapons and provide the armoring scheme of weight advantage to measure by its RHA that has saved how much weight with stopping specific weapon.This advantage may be calculated protection ratio, and this protection ratio equals to stop the weight that weapon penetrates required RHA, divided by the weight of the system that proposes that can stop identical weapon.This weight is calculated with the per unit frontal area that the direction along the expected trajectory of this weapon obtains.
Therefore, need a kind of plate armour, this plate armour can defend to come from the projectile of anti-armor apparatus under the situation that does not need excessive armor thickness.Preferably, making the material that this plate armour adopts can and be incorporated in the vehicle design with the reasonable prices manufacturing, even more preferably, can be added into existing vehicle.
Along with increasing with respect to the threat of armored vehicle and becoming more varied, need armoring combination or armor system defend full spectrum of threats.The present invention can strengthen protecting vehicle and required universal design feature with respect to military strike rifle bullet, explosive shrapnel and landmine explosion thing.The armor system of the application's record has improved armored vehicle to comprising the protection level of EFP and hybrid explosive.

The specific embodiment
At length with reference to the preferred embodiments of the present invention, the example illustrates in the accompanying drawings now.Under possible situation, in institute's drawings attached, will use identical Reference numeral to refer to identical or similar parts.
According to the present invention, provide a kind of armor system that is used to defend solid projectile., the present invention and embodiment penetrate the device of its main function long and thin metal " jet " that to be defence made jointly by shaped charge and heavy solid projectile though can stoping to be formed with the relative non-elongated heavy solid metal projectile that advances by destructor of producing or the explosive made temporarily.The parameter of this system may be selected to the defence particular projectile, if its weight, density, speed and size are known.The parameter of this system is the mechanical attributes (wave propagation velocity is impacted in ultimate hot strength, hardness, elastic modelling quantity, fracture toughness and supercharging) that constitutes the material layer of layer of the present invention, interval of each layer (interfloor distance, the i.e. thickness of dispersion space) and the essence that is arranged on any material in the interlayer space.
Some embodiments of the present invention have a plurality of projectioies on the inner surface of at least one armour plate in this system.The purpose of a plurality of projectioies is that the solid projectile that makes outburst pass the inner surface of this plate is disperseed on the inner surface.The mechanism that the inner surface atarting material disperses can be different from the mechanism of the lip-deep projection that projectile clashes into, and still, does not consider this mechanism, and the projection on the inner surface makes from the dispersion of materials of its outburst, realizes one of them target of this system thus.The shock wave that passes this system is provided at the energy of outburst at the inner surface place of this plate, but the direction of outburst will be transmitted the adjacent material of the inner surface that enters by the shape of the inner surface of the material that wherein has shock wave energy and with impact energy and determine.When the material that receives impact energy from solid has obviously lowly when forcing the shock wave transfer rate, this energy will be by in the surface reflection and do not transmitted.For example, the material that wherein has shock wave be solid (for example, aluminium or steel with 5000m/conduction second shock wave), the material that receives this shock wave is air (has have only 330 meter per seconds force the shock wave transfer rate), this not matching will cause energy to gather on related plate surface, causes outburst then.A kind of form of this outburst is called as " cracked ".
The material properties of the solid material of formation plate can influence the dissipation and the Momentum Transfer of energy and leave penetration line, has influenced cracked how the generation at the metallic plate rear portion thus.If this material is frangible (being similar to most of potteries), hardness advantage at front surface will be lost at the cracked rear surface of appearance so, stretch because this material has low-down fracture, this material is cracked to be small pieces, less energy is taken away left penetration line.When big fragment has 10% or when more rupturing tension values, big independent fragment can result from the material that is similar to steel and other metals.Having the high tensile that is associated with high tension values (is similar to and surpasses 30,000lbs./in.
2, for aluminium) the bigger energy of material require pull apart big fragment.By the law of conservation of momentum, will cause leaving the rear portion of plate and be carried striding across dispersion space to the speed of the parts of next baffle and producing bigger decline with respect to the heavy fragment of the quality of impacting projectile.
This system the outermost layer place of this armor system or near comprise under the situation of fibrous material layer, fibrage is by resisting the expansion of opening wherein by the extreme high tensile of the fiber that is made of fibre plate, thereby weakened the energy of penetrable material.Even penetrated by elongated penetrator, this initial openings can resist expansion and apply high shearing force on the side surface of elongated penetrator.The energy that this has slowed down the speed of penetrator and has reduced penetrator.This following one deck that has increased in this armor system can be defendd penetrator or the possibility of the penetrator that further slows down, and what make the system will meet with penetrator layer can have its a chance of better defence.
As hereinafter will be more detailed disclosed like that, this system is made of a plurality of plywoods that are called as the dispersion space separation.In certain embodiments, be used to cause impinge upon lip-deep or from the material production of surface outburst disperse come from outside or the projection of inner surface can use two apparent surfaces at any one plate of this system, on the outmost surface, on the inner surface, perhaps do not act on from the teeth outwards.
In another embodiment, therefore under the known situation of projectile track (be its expection penetration line), armour plate can tilt to make penetration line no longer perpendicular to outer surface.In this embodiment, at least one armour plate tilts with respect to the expected trajectory of this projectile.Preferably, each plate can be with respect to 20 ° at the expected trajectory angle of inclination of projectile or more.
According to the present invention, provide a kind of external rigidity armour plate with outer surface and inner surface.This plate can have parallel opposing flat surfaces, and perhaps in a particular embodiment, the surface of the plate that projectile will at first clash into (" outward " surface) can comprise a plurality of projectioies on the outer surface.These projectioies are arranged to the broken at least in part solid projectile that impinges upon on this plate outer surface.The size of projection and structure are determined by the attribute of projectile and the material that forms this plate.The purpose of the projection on the outer surface of first plate is not to destroy projectile, but the elongated metal " jet " of deflection, this jet is to move relative to the front portion of heavy projectile at a high speed, and projectile moves with lower speed along identical track.The feature of this penetrator is to be called hybrid weapon here.As further disclosed here, main purpose of the present invention is along with projectile passes this armor system and causes the dispersion of projectile.The implication of disperseing is the initial track that projectile is left in the part of projectile and any part deflection that forms the material of the layer in this system.
Outer armor layer can be made of the agglomerated material of selecting from following group basically: carborundum, boron carbide, the mixture of aluminium oxide and zirconia and aluminium oxide.One embodiment of the present invention comprises CeraShield
TMThe outer armor layer of pottery of pottery, the U.S. 80403, Colorado, Golden, the Group CoorsTek of 16000Table Mountain Parkway, Inc.'s
The product of Armor.Other preferred embodiments comprise metal, for example steel, aluminium alloy and titanium alloy.
According to the present invention, provide a kind of fiber-reinforced sheet armor that is fixed to the inner surface of outside armour plate.This fiber-reinforced sheet armor comprises a plurality of fibers, has the ultimate hot strength above 2.5GPa, polymer-bonded to form this sheet by around this fiber.Do not have in theory when bonded, think that any jet that penetrates this fibrolaminar material must side direction separate this fiber and therefore apply tensile load on fiber.When fiber enough strong (having high tensile), around this jet of materials limitations of jet and its speed that slows down significantly.Because jet destroys plate armour by the inertia of elongated (being formed by explosive) penetrator, so the reduction of the speed of this jet reduces its validity significantly.Because fibrage be in the system of the present invention some armor layer wherein first one of, so the back the layer can more easily defend this jet.
Immediate development in the fibre technology has produced has the fiber that surpasses the hot strength of 3GPa in relative light material.In a preferred embodiment, the reinforcing fiber armor consists essentially of the material of selecting from following group: poly-to two formyl p-phenylenediamine (PPD) (poly-paraphenylene terephthalamide), the tension guide high density polyethylene (HDPE), the tension guide polyester of high density, based on the polymer of the two imidazoles (pyridobisimidazole) of pyrido, and silex glass.
Preferably, fiber-reinforced sheet armor sheet consists essentially of the High molecular weight polyethylene of tension guide, and especially linear polyethylene has 600,000 to 6,000,000g/mol or higher super high molecular weight.Thereby these fibers are bonded together by the polymer matrix material and form sheet products, and thermosetting numerical value for example is such as phenolic resins, epoxy resin, vinyl ester resin, mylar, acrylates resins etc., perhaps polar thermoplastic matrix material is such as poly-(methyl) methyl acrylate.Especially preferred such fiber-reinforced sheet armor can be from the product of the DSM Dyneema of the Mauritslaan 49 of the Urmond of the P.O.Box 1163 of the 6160 BD Geleen of Netherlands
Obtain.
Another preferred fiber-reinforced sheet armor sheet consists essentially of the composite plate of being made by high molecular weight polypropylene.In this product, the adhesive tape line of high molecular weight polypropylene is woven into fiber.Thereby multi-layer fiber uses low-molecular-weight polypropylene to pile up under heat and pressure effect as matrix and strengthens and forms rigid disk.The certain preferred reinforcing fiber armor of being made by this types of material is at the commercial MTF of being known as sheet, the Milliken﹠amp of the Milliken Road902 of the P.O.Box 1926 of the Spartansburg of the Southern California of the U.S. 29303; The product of Company.
As embodying here, and in Fig. 1, schematically describe, there is the parallel plate of a series of cardinal principle 10, comprise outer armour plate 12, fiber is armour plate 12 ', interior armor plate 14 and inner armour plate 15 outward.In described embodiment, fibrous armor layer 12 ' is bonded to the outer armour plate 12 on the surface, inside 13 of armour plate 12.In other embodiments, can use machinery to tighten up fibrous armor layer 12 ' is bonded to outer armour plate 12 or fibrous armor layer 12 ' is limited between the adjacent armour plate, not have the dispersion space (not shown).In this embodiment, the outer surface 11 of armour plate 12 is flat.
As used herein, " armour plate " is plate-shaped member, is arranged so that projectile forms fragment, deflection or dispersion or absorbs energy to promote its other parts destructions by this system from projectile.It can be known armour plate material (promptly, high-intensity metallic plate), intensity is lower than the metal plate of conventional armor plate, perhaps makes the tabular parts of fibrous material used in this invention, acts on projectile and makes other elements in the armor system defend projectiles.In a preferred embodiment, inner armour plate 15 can comprise armored hull.
Such as here realization and Fig. 1 described, this system comprises first dispersion space 18, separating plate 12 ' and 14, distance 19, the second dispersion space 20, the outer surface of series of plates 10 is surfaces 11 of plate 12.
According to the present invention, series of plates is separated by dispersion space.As mentioned above, dispersion space is the space between the adjacent panels, and the effect of dispersion space is to allow to disperse by material production side direction wherein.The meaning of term lateral is to depart from the direction of the initial flight line certain angle of projectile, i.e. its track.Mobile object is dispersed many more, and the energy concentration that impinges upon on next pantostrat is just few more.In addition, interfloor distance big more (thickness of dispersion space is big more), the kinetic energy of being arranged by mobile material of every surface area is just few more.Clearly, if dispersion distance is very big, so a large amount of kinetic energy will diffuse out and lose from original penetration line, but resulting stepped construction is with thick unrealisticly.On the other hand, if the thickness of dispersion space is too small, moving matter is not disperseed so, and its kinetic energy and momentum are not dissipated, and it can have the layer subsequently that enough energy and concentration are destroyed this system.The overall direction of those skilled in the art by providing here can be designed a system in conjunction with following example, defends the particular projectile that moves with specific speed along particular track or the mixture of projectile.
In a preferred embodiment of the present invention, first armor layer comprises the hard material of the relative thin on its outer surface, ceramic material layer for example, thus cause the broken and/or distortion of projectile.In this embodiment, the function of first armor layer is some energy that absorb projectile, and it is flattened (at least some of its quality of lateral translation) and reduces its speed significantly.Adjacent fibrous armor layer 12 ' absorbs and comes from the energy of projectile and reduce its speed.
The weapon that the present invention can have place to show one's prowess is described among Fig. 2 A and the 2B.In those figure, thereby projectile 16 has been formed by destructor and has had relative to part 16 ' heavy and that move at a slow speed.In part 16 ' front portion is the elongated material " jet " that moves at a relatively high speed along same trajectories.Disclosed as preamble, because jet with high-speed mobile and have relative small cross section area, threatens so it will produce significantly armor system.This especially like this, because run into target (and generation effect on the target that this jet may meet) afterwards at jet momently, the target of same section receives heavy 16 ' the big relatively impact that comes from projectile in the same position that runs into jet.
Fig. 2 B has described armour plate 12 and inner panel 12 outside jet passes " afterwards, the embodiments of the invention before the portion of counterweight mutually of projectile 16 ' has been applied to its energy armor system.At this moment, the contractive effect of the fiber outside plate jet part 16 that slowed down " speed; even outer armor layer 12 and fiber outside plate 12 ' are destroyed, the energy that absorbs by fibrage 12 ' and will be by can broken outer armour plate 12 and make the 12 ' distortion of fiber outside plate and the energy of the part 16 ' absorption of projectile 16 that may broken fiber outside plate 12 ' will weaken energy in the projectile 16 significantly.This has increased projectile 16 significantly will be by the possibility of the remainder of armor system defence, and here, remainder is a layer 14 and 16.
Further preferably, the impact wave propagation velocity in the armour plate will obvious speed faster than penetrator.The hardness of armour plate can be born then, and geosutures provide the favourable geosutures that Fig. 2 B is described as angle [alpha] by deflection and resonance.Angle [alpha] is big more, and many more energy are absorbed by the distortion of the plate that is just being penetrated, the weight of penetrator and the armoring part that adheres to this and big more.
It is about 5,000 meter per seconds that wave propagation velocity is impacted in pressurization in steel and the aluminium alloy plate, and like this, if the speed of bump projectile is approaching or be higher than this, penetration will more be similar to HC so.The density that penetrates the material that depends on that it penetrates of HC, the material that density is low more show well more.When in the face of high-speed impact, the aluminium plate armour is preferable over steel armor, but when speed was reduced by previous penetrating, it is effective that so hard steel plate also can become.Have the speed of 2500 meter per seconds under the EFP normal condition, perhaps slower, hybrid have a littler and lighter traction penetrator that moves with 3000 to 3500 meter per seconds, and they more are difficult to stop like this.
In case penetrator 16 " slowed down with relative heavy projectile part 16 ' and be deformed into a projectile basically, projectile penetrates and shears each plate in the mode that can predict so.The quality of projectile and length velocity relation meet conservation of momentum relation: M
