Abstract

The utility model discloses a bulletproof armour for helicopter seat, including the armour, the armour is by constituting through epoxy glue fixed boron carbide ceramic splice plate, carbon fiber intermediate lamella and the high molecular weight polyethylene board that bonds in proper order, and the outside cladding of armour bonds and has brocade silk sail silk fabric layer. The beneficial effect of the utility model: the utility model discloses the bulletproof armour can lighten the weight of protection armoured 15 on the same protecting area and barrier propterty's basis, can reduce taking helicopter cabin inner space simultaneously.

Description

A kind of bulletproof armour for Helicopter Seat

Technical field

The utility model is related to bulletproof armour technical field, it particularly relates to a kind of for the shellproof of Helicopter Seat It is armoring.

Background technology

The bulletproof armour of Helicopter Seat it has been applied at present, its performance is to prevent 12.7mm bore armor-piercing incendiaries from existing Firing Velocity is the armor-piercing incendiary of 488m/s at 1000m, and its shooting performance is relatively low, it is impossible to the hit velocity that Defence Standard specifies Not breakdown for the armor-piercing incendiary shooting of 488m/s, while its weight is very heavy, shellproof plate thickness is big (about 28mm), identical anti- The lower weight of mask product is unfavorable for that greatly (empty weight is the finger being of great value for helicopter for the load-carrying of helicopter and mobility Mark), at the same Protective armor be it is plate, it is impossible to accomplish abnormally-structured, it is reasonable to space using exist very big defect (due to Helicopter inner space is less, and the bulk design of equipment is particularly important).

Number of patent application discloses a kind of ballistic resistant armor articles for the Chinese patent application of 201480023646.X, concrete public Open：Its include at least one towards projectile ground floor and at least one second layer, at least one second layer is neighbouring At least one ground floor and towards object to be protected, wherein under ballistic event, at least one ground floor can The irreversible transition that experience strike causes.Though above-mentioned patent application can improve the barrier propterty of bulletproof armour, do not account for The density and volume of bulletproof armour.

Utility model content

The purpose of this utility model is to propose a kind of bulletproof armour for Helicopter Seat, can ensure helicopter Reduce the density and volume of Helicopter Seat bulletproof armour on the basis of seat ballistic requirements.

To realize above-mentioned technical purpose, what the technical solution of the utility model was realized in：

A kind of bulletproof armour for Helicopter Seat, including armour, the armour by by epoxide-resin glue according to The secondary fixed boron carbide ceramics splice plate for boning, carbon fiber intermediate plate and High molecular weight polyethylene plate are constituted, the armour Outside cladding is bonded with bright and beautiful silk sail silk fabric layer.

Further, the thickness of the boron carbide ceramics splice plate is 11mm, and the thickness of the carbon fiber intermediate plate is 3- 5mm, the thickness of the High molecular weight polyethylene plate is 9-10mm.

Further, the boron carbide ceramics splice plate intersects fissure of displacement splicing construction and arranges in T fonts.

Further, the armour is made up of the flat board of centre and the arc kink being wholely set with flat board two ends.

The beneficial effects of the utility model：The utility model bulletproof armour can be in identical pretective acreage and barrier propterty On the basis of, mitigate the weight of Protective armor 1/5, while the occupancy to space in helicopter cabin can be reduced.

Specific embodiment

With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clearly Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the utility model, rather than the reality of whole Apply example.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art are obtained is belonged to The scope of the utility model protection.

As shown in Figure 1-2, a kind of bulletproof armour for Helicopter Seat according to embodiment of the present utility model, Including armour, the armour is by by epoxide-resin glue successively the boron carbide ceramics splice plate 1, carbon fiber of fixed bonding Between plate 2 and High molecular weight polyethylene plate 3 constitute, the outside cladding of the armour is bonded with bright and beautiful silk sail silk fabric layer 4.

When specifically used, using boron carbide ceramics splice plate 1 as out surface, bullet is beaten on boron carbide ceramics splice plate 1 Formed reverse taper holes, can farthest destroy the impulsive force of bullet, High molecular weight polyethylene plate 3 as backboard, by plasticity Deformation absorbs the last energy of bullet, reaches the effect for making the utility model bulletproof armour not breakdown.In addition, on the outside of armour The bright and beautiful silk sail silk fabric layer 4 of cladding bonding can not only further improve the impact capacity of boron carbide ceramics splice plate 1, and can The fragment hit down by bullet on secondary utilization armour makees further cushioning effect to bullet.

In order that the utility model bulletproof armour disclosure satisfy that in hit velocity be 488m/s and bore wearing for 12.7mm Not breakdown under the strike of first firebomb, the thickness of the boron carbide ceramics splice plate 1 is preferably 11mm, in the middle of the carbon fiber The thickness of plate 2 is preferably 3-5mm, and the thickness of the High molecular weight polyethylene plate 3 is preferably 9-10mm.

In the above-described embodiments, as shown in figure 3, the boron carbide ceramics splice plate 1 intersects fissure of displacement splicing construction in T fonts Arrange.For the boron carbide ceramics splice plate 1 of identical protection volume, fissure of displacement structure is intersected than cross-shaped configuration using T fonts Intensity can have greatly improved.

In the above-described embodiments, in order to ensure bulletproof armour barrier propterty do not reduce in the case of reduce the utility model Occupancy of the bulletproof armour to interior of aircraft space, the armour is by the flat board 5 of centre and the arc being wholely set with the two ends of flat board 5 Shape kink 6 is constituted.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
