Technical field

The invention belongs to guided missile launcher and protection technology fields, and in particular to a kind of directional separation structure and orientation point From entirety break through formula firing box sealing cover.

Background technique

Firing box sealing cover is one of the key components of guided missile launcher, and speed of uncapping is that can influence guided missile One of an important factor for rapid fire.Requirement with modern army to quick fight capability and precision strike target capability is continuous It improves, it is necessary to further increase firing box and uncap speed.Currently, the sealing cover for firing box sealing mainly includes firing box Front cover and firing box rear cover, when wherein guided missile erects placement, being located above is firing box front cover, and underlying is firing box Rear cover, main material are to have many advantages, such as that specific modulus is high, specific strength is high, ageing-resistant, light and can design strong fiber reinforcement Polymer matrix composites, the main unpack format with firing box mainly includes following two form:

More valve separate types: in friable material, (polyurethane foamed material and epoxy resin change this kind of unpack format more application Property material etc.) production firing box front cover.Front cover will open under the effect of bullet bursting power at lid bullet position, then in bullet Make lid along weak zone position more valves separation around of predetermined design under the effect of body outlet.Although this separate mode reduces The size and weight of chorista, but the posture of fragment is difficult to control after the separation lid separation of more valves, fragment can set transmitting Standby and surrounding devices cause potential security threat.

Entirety breaks through formula: entirety breaks through formula lid and is used primarily in firing box rear cover, carries out overall separation to front cover both at home and abroad Example have not been reported yet.Entirety break through formula lid because its separation after separation weight it is big, the fragment generated after separation because Combustion gas stream recoil effect can cause security threat to emitter and surrounding transmitting equipment.

For these reasons, the lid isolated orientation is made to dish out for the fragment after preventing separation to emitter and week Enclosing transmitting equipment causes this problem of security threat extremely crucial.It is less to the research of directional separation formula lid both at home and abroad, China A kind of orientation is proposed in 104864773 A of patent document CN to dish out composite material Fragile cap and preparation method thereof.Its by The uncut area that zone position retains certain length is separated, to realize that Disengagement zone bearing capacity is of different sizes, to realize that lid exists Separated region cutting position first destroys when destruction, destroys after non-cutting part.Since composite material Disengagement zone is needed by artificial It is bonded manually again after cutting, and existing directional separation technology is difficult to control chorista and cutting area ratio, will affect lid Body breaks through the stability of pressure.Disengagement zone will affect bonding quality stability, especially for large scale because there is uncut area Frangible lid, this molding mode control difficulty is larger, while Disengagement zone bonding difficulty is larger and bonding quality is not easy to control, Therefore this mode has some limitations in the application.

Therefore, against the above deficiency, the present invention is badly in need of providing a kind of directional separation structure and the entirety of directional separation is broken through Formula firing box sealing cover, to solve the above problems.
