Description

Take driftage protective structure

Technical Field

The invention relates to the technical field of missile penetration resistance protection, in particular to a structure with yaw protection.

Background

The existing commonly used protective structure forms are mainly layered protective structures, and are respectively called as a camouflage layer (camouflage), a shell shielding layer (penetration resistance), a distribution layer (explosion shock wave buffering) and a structural layer (main body support) according to different functions, and the striking resistance of the protective structure is mainly embodied on the shell shielding layer. In order to effectively strike important targets such as a single-machine shelter library, a control center and the like, the form of the missile is gradually changed from low penetration high explosion to high penetration low explosion, so that higher requirements are provided for penetration resistance of a protection structure, requirements for explosion impact resistance are reduced, and the existing protection structure is not fully adjusted.

Currently, there are two main types of ballistic layers: one is an active (or called reactive) protection technology, namely before the tail end of the trajectory of an incoming conventional weapon is not contacted with a bullet shielding layer, the bullet shielding layer is damaged by a reaction system of the bullet shielding layer, so that the bullet shielding layer deviates from a target and even loses penetration capability; the other is passive (or called comprehensive) protection technology, namely, the self-resisting capability of the bullet-shielding layer is improved. The passive protection technology mainly has three research directions: 1) adopting structural measures which mainly comprise improving the surface hardness of the shell shielding layer or changing the surface geometric shape and changing the geometric shape between layers, for example, spherical cast iron or spherical ceramic is used as the surface of the shell shielding layer, or a honeycomb interlayer is sandwiched between the shell shielding layers, so that penetrating shots deflect; 2) the high-strength composite material is adopted, and mainly a composite material layer with strong penetration resistance is adopted, such as corundum block stone concrete, steel fiber concrete containing steel balls and the like; 3) and the effective combination form of the layered structure is adopted, and the heterogeneity of each protective layer is utilized to influence the penetration of the elastomer.

However, the existing bullet-proof layer system has the problems of poor penetration resistance (common concrete structures applied in a large amount in practice), difficulty in site construction, difficulty in quality guarantee (high-strength concrete and composite material concrete structures are researched more), weak parts (a ceramic shell yaw layer, the difference of penetration resistance effects on the shell and between the shells is obvious), poor economy and the like in different degrees.

The specific test and theoretical research results of the bullet-proof layer at home and abroad are as follows: foreign stone bullet shielding layers, concrete hollow triangular prism bullet shielding layers, concrete grid plate bullet shielding layers, high-strength concrete bullet shielding layers and steel fiber concrete bullet shielding layers; the domestic spherical shell type bullet shielding layer, the high-strength concrete short column bullet shielding layer, the high-strength composite material bullet shielding layer, the multi-layer composite bullet shielding layer and the like. The bullet shielding layers achieve better bullet shielding effects in tests, but are not applied in practice. The most practical applications are also common concrete ballistic layers, mainly because these techniques have the following disadvantages: 1) compared with the large volume and large area in the actual construction of protection engineering, the sizes of the test piece and the target body adopted in the test process are obviously different, and the structure with good effect in the test process is not easy to realize in practice, for example, the large area pouring is difficult to realize under the current construction condition of the composite material concrete which is researched in a large amount at present; 2) most of the existing yawing devices have weak parts to a certain degree, and the striking parts of the elastic bodies can seriously influence the yawing effect, for example, a ceramic shell yawing layer, the elastic bodies strike on the shell and between the shells, the yawing effect is greatly different, and a stable and good yawing effect cannot be provided; 3) the economy is poor, if a common concrete bullet-proof layer is used, a sufficient penetration resistance effect is required, and the sufficient thickness is required, so that the economy is obviously reduced, and if the common concrete bullet-proof layer is used as composite concrete and high-strength concrete, a good penetration effect can be achieved, but the site construction and the material cost are too high.
