Embodiment 1

[0028] Such as figure 1 Shown: A multi-lobed composite launching box cover, with high-strength glass fiber cloth and epoxy resin as the main materials, designed and manufactured by step-lamination method. Specifically, a kind of multi-lobe type composite launch case cover of the present invention comprises 1, frame, and described frame 1 is circular; The joint of the side sub-cover unit adopts a 45° V-shaped groove structure, the inside is filled with AB glue, and the outside is pasted with 2 layers of glass fiber cloth strips; 3. The side sub-cover separation area, the side sub-cover separation area 3 is located Between the side sub-cover units, adopt the same structure as the throwing body separation zone 2; 4, the top sub-cover separation zone, the top sub-cover separation zone 4 is located at the junction of the top sub-cover 6 and the side sub-cover unit 5 , adopts the same structure as the projectile separation area 2; 5, the side sub-cover unit, the side sub-cover unit...

Embodiment 2

[0056] Such as Figure 4 Shown: A multi-lobed composite launching box cover, with high-strength glass fiber cloth and epoxy resin as the main materials, designed and manufactured by step-lamination method. Specifically, a multi-lobed composite launch case cover of the present invention includes 1. a frame, and the frame is circular; 2. a throwing body separation area; 3. a side sub-cover separation area; 4. a top sub-cover Cover separation area; 5. Side sub-cover, the side sub-cover unit is formed by cutting the ejector body, with a total of 8 petals; 6. Top sub-cover, the top sub-cover and the side sub-cover unit are made In the same way, a total of 1 petal. This embodiment is adopted when the mass of the launching box cover is too large, and the unit mass of the projectile is alleviated by increasing the quantity of the side sub-cover units. Therefore, the multi-lobed launch box cover can effectively solve the problem of large quantities of objects thrown by the launch box...

Abstract

The invention relates to a multi-petal composite material launching box cover and a preparation method thereof and belongs to the technical field of missile launching. The multi-petal composite material launching box cover sequentially comprises a frame (1), a side sub-cover (5) and a top sub-cover (6). The side sub-cover (5) is connected with the frame (1) through a thrown body separating area (2), the top sub-cover (6) is connected with the side sub-cover (5) through a top sub-cover separating area (4), the side sub-cover (5) is evenly divided into 4-8 side sub-cover units in the circumference, and the side sub-cover units are connected through side sub-cover unit separating areas (3). Under the effect of missile launching tail flow, the launching box cover is broken into a plurality of sub-covers to fly away from a launching box, and accordingly missile launching is not influenced. The problem that a thrown object of the fragile cover is high in mass is solved, and the threat to surrounding devices and workers caused by the thrown object is effectively reduced.

Description

[0001] Field technology [0002] The invention relates to a multi-lobed composite material launch box cover and a preparation method thereof, belonging to the technical field of missile launch. Background technique [0003] The design of the missile launching box cover is one of the important factors affecting the rapid response ability of the missile. Therefore, when developing the missile storage launching box, the design of the box cover is very important. The box cover is mainly able to withstand a certain pressure difference, has good sealing performance, and can be opened quickly when launching a missile. In order to meet the above requirements, the cover of the missile launching box used to use a mechanical cover, an explosive bolt opening cover, etc. (see US Pat. If the mechanical opening cover needs to be opened by a hydraulic system, the mechanism is complicated, which not only increases the weight of the launch box and delays time, the opening response of the expl...
