Abstract
The invention provides one and possess sealing property, can bear certain positive pressure, when guided missile outlet, forward easily broken, to guided missile warhead not damaged, to trajectory without interference, when adjacent case MISSILE LAUNCHING, can bear again the frangible formula firing box case lid that adjacent case Missile Plume impacts, reverse pressure-bearing ability is strong. Frangible lid adopts that Polyurethane foam specific strength is high, fragility good frangible, heat-proof quality is good, convenient formation, and other material cohesive good, there is the corrosion-resistant Anti-mildew capability of good oil resistant, add appropriate antiaging agent, can improve the ageing resistace of material. Feature energy-conservation, efficient, that equipment investment is few, product quality is high that cold molding moulding has, therefore, frangible cap body material adopts rigid polyurethane foam plastics cold molding moulding.
Description
Technical field
The present invention relates to a kind of for the launch a guided missile firing box of armament systems of multi-joint vanning formulaProtecgulum. When particularly addressing one and utilizing MISSILE LAUNCHING, body self-energy rushes firing box protecgulumBroken, adopt polyurethane material cold molding moulding, can bear adjacent case Missile Plume gas shock power,The frangible formula projectile storage and transportation firing box protecgulum that forward is frangible and reverse non-friable.
Background technology
The box transmitting of tactical missile can effectively improve war preparedness guided missile on duty in case service life andShorten missile response time, when box launching a guided missile, case lid should be able to be opened reliably and lock,And ensure that missile flight and missile wing launch not interfered. At present external firing box case lid generally adoptsThrowing type, open-type. Throwing type, open-type firing box cover structure complexity. Safety in utilization,Poor reliability, explosion is also opened and is easily produced stained to guided missile. If while utilizing MISSILE LAUNCHING selfEnergy breaks through firing box protecgulum, will make firing box front-cover structure simplify, safe and reliable.But employing is broken through formula case lid and must be solved following two problems: when (1) case lid is broken through by bullet, wantRequire in accordance with regulations fragmentation, ensure that missile flight and missile wing launch not interfered, also will prevent bulletBe damaged because bearing excessive impulsive force, but guided missile when store in firing box, need be filled with oneThe protective gas of constant-pressure, therefore, case lid should possess easily fragmentation of forward, can bear one againThe ability of fixed positive pressure; (2) in the time of the adjacent case MISSILE LAUNCHING of multi-joint dress firing box, adjacent caseMissile Plume air-flow has a larger surge to case lid, and case lid should have enough oppositely holdingPressure energy power, is not rushed broken by the wake flame air-flow of adjacent case guided missile.
Shanghai Spaceflight Equipment Manufacture Head Factory is combined with the 805 research institute of Shanghai Academy of Aerospace Industry before this" projectile storage and transportation firing box breaks through type protecgulum " (national defence patent number 93112254.6) tool of developmentStandby forward is broken, the ability that can bear again certain positive pressure easily. But fly at live shellWhen test, the fragmentation of generation lid is irregular, four side breaks not simply, have residue adhesion,More seriously repeatedly there is Missile Plume air-flow by the adjacent case case lid punching of multi-joint dress firing boxBroken, affect the smooth transmitting of adjacent case guided missile.
The forward of frangible formula launching box cover is wanted frangible and is oppositely answered non-friable operating characteristic, requirementIts forward has little pressure-bearing energy cutter, reverse will have large bearing capacity, and these two kinds of pressure are largeLittlely differ an order of magnitude. This just requires to break through, and the frangible case lid of formula enbrittles, intensity distribution is closedReason, reverse pressure-bearing ability is high. This has brought larger to aspects such as selection, structural design, manufacturesDifficulty.
Summary of the invention
The object of this invention is to provide one and possess sealing property, can bear certain forward and pressPower, when guided missile outlet, forward easily broken, to guided missile warhead not damaged, to trajectory without interference,When adjacent case MISSILE LAUNCHING, can bear again easy that adjacent case Missile Plume impacts, reverse pressure-bearing ability is strongBroken formula firing box case lid.
In order to realize foregoing invention object, frangible formula firing box case lid of the present invention is by frangible lidWith case lid mouth frame composition, frangible lid is that surrounding has horizontal lid frame to become one with middle cover sports associationThe pot shape body of body, lid frame glueds joint and is connected with case lid mouth frame, case lid mouth frame and firing box casingConnect, adopt rigid polyurethane foam plastics, cold molding moulding, is characterized in that, four of lidSide is arc, and the top of lid is plane, between lid and the horizontal frame of lid surroundingBe provided with cracking groove, and be furnished with cross cracking groove at arc lid medial surface, cracking groove triangle,Cracking segment thickness is 1: 7.5 with the ratio of non-cracking segment thickness.
With respect to prior art, the material of the frangible lid of the present invention adopts hard polyurethane foams to mouldMaterial, cool molded. Between arc lid and four lid frames, be provided with cracking groove, and at arcLid medial surface is furnished with cross cracking groove, and cracking groove is triangle, cracking segment thickness andThe ratio of non-cracking segment thickness is 1: 7.5. The top of arc lid is plane. Plastics are than strongSpend high, fragility good frangible, heat-proof quality is good, convenient formation, good with other material cohesive,There is the corrosion-resistant Anti-mildew capability of good oil resistant, add appropriate antiaging agent, can improve materialThe ageing resistace of material. That cold molding moulding has is energy-conservation, efficient, equipment investment is few, product matterMeasure high feature.
Easily broken and broken on request for ensureing frangible lid, while preventing from breaking through again, bullet holdsBe subject to excessive impulsive force, between arc lid and four lid frames, be provided with cracking groove, and at arcShape lid medial surface is furnished with cross cracking groove, and cracking groove is triangle, cracking segment thicknessWith the ratio of non-cracking segment thickness be 1: 7.5, can make guided missile outlet time case lid body impactThe impulsive force of easily breaking under power effect and by regular breaks, lid, guided missile warhead is produced is little,Disperse to four sides at bullet impact force action lower cover fragment, lid fragment does not affect guided missile missile wingLaunch and to trajectory without interference.
In order to improve the reverse pressure-bearing ability of lid, four lateral layout of lid are arc, lidTop be plane, lid is had highly low, the feature that reverse pressure-bearing ability is good.
