装 甲 板 Armor plate
発明の技術分野 TECHNICAL FIELD OF THE INVENTION
本考案 は、 戦斗車両等の耐弾性を要求 さ れ る 構造物に 用 い る 装甲板 に関す る 。 The present invention relates to an armor plate for a structure requiring high elasticity, such as a fighter vehicle.
発明の背景技術 BACKGROUND OF THE INVENTION
従来、 戦斗車両の外装材 と し て用 い ら れて い る 装甲扳 の多 く は単一鋼板に よ り 形成 さ れ、 そ の装甲板の耐弾性 能向上は鋼板の厚 さ を大 き く し た り 、 鋼板 自 体の材質改 善に よ り 耐弾性能を向上す る こ と で行な われてい る 。 Conventionally, most of the armor used as exterior materials for battleship vehicles is formed from a single steel plate, and the improvement in the elasticity resistance of the armor plate increases the thickness of the steel plate. This has been done by improving the material quality of the steel sheet itself and by improving the ballistic resistance.
し か し なが ら鋼板の厚 さ を大 き く す る と 車両重量が重 く な り 走行性に 問題があ る か ら鋼板の厚 さ に は限度があ り 、 網板 自 体の耐弾性能向上に も 限度があ る ばか り か、 鋼板が高価 と な る か ら 、 装甲板の耐弾性能に は限度があ る However, if the thickness of the steel plate is increased, the vehicle weight becomes heavy, and there is a problem in traveling.Therefore, the thickness of the steel plate is limited, and the net plate itself has to withstand the resistance. There is only a limit to the improvement of ballistic performance, and the steel plate becomes expensive, so there is a limit to the bulletproof performance of the armor plate
発明 の概要 Summary of the Invention
そ こ で、 本考案は前述の課題を解決で き る よ う に し た 装甲板を提供す る こ と を 目 的 と す る 。 すな わ ち 、 弾丸の 鋼板貫徹力 は弾丸が鋼板に垂直に 当 っ た場合を最大 と し 角度が付 く に従 っ て急激に網板貫徹力が低下す る こ と 、 弾丸の鋼板貫徹中 に お い て は硬 く て貫徹抵抗の犬な る 方 向 よ り 柔 ら か く て貫徹抵抗の小な る 方向 に進む こ と 、 の Therefore, the purpose of the present invention is to provide an armor plate that can solve the aforementioned problems. That is, the bullet penetration force of the bullet is maximized when the bullet hits the steel plate perpendicularly, and the penetration force of the bullet decreases sharply as the angle is increased. Inside, it is necessary to move in a direction that is softer and less penetrative than a dog that is hard and penetrable.
2 点に着 目 し て工夫 さ れた耐弾性能が飛躍的 に 向上す る 装甲板を提供す る こ と を 目 的 と す る 。
上記 目 的を達成す る た め に、 本発明 に よ れば、 主装甲 板の前面 に 、 耐弾性能の優れた材料よ り 成 る 複数の 中間 板を間隔を置い て斜め に配設 し、 かつ 隣接す る 中間板間 に耐弾性能の劣 る 充填材を設けた複合板を取付けた装甲 板が提供 さ れ る 。 こ れに よ つ て、 弾丸を中間板に よ っ て 斜め に貫徹 さ せて運動エネ ルギー を低減 し た後 に主装甲 板に衝突 し 、 弾丸が主装甲板を貫徹す る こ と がな い よ う に で き る 。 The aim is to provide an armor plate that has been devised with a focus on two points and has a markedly improved bullet resistance. In order to achieve the above-mentioned object, according to the present invention, a plurality of intermediate plates made of a material having excellent ballistic resistance are arranged diagonally at the front of the main armor plate. Further, an armor plate provided with a composite plate provided with a filler having inferior bulletproof performance between adjacent intermediate plates is provided. As a result, the bullet penetrates obliquely by the intermediate plate to reduce the kinetic energy, and then strikes the main armor plate, so that the bullet penetrates the main armor plate. You can do it.
図面の簡単な説明 BRIEF DESCRIPTION OF THE FIGURES
第 1 図 は本発明の具体例を示す断面図、 そ し て第 2 図 は弾丸の衝突状態説明図であ る 。 FIG. 1 is a cross-sectional view showing a specific example of the present invention, and FIG. 2 is an explanatory view of a collision state of a bullet.
好ま し い具体例の詳細な説明 Detailed description of preferred examples
以下、 添付の 図面を参照 し て本発明 の具体例を詳細 に 説明す る 。 Hereinafter, specific examples of the present invention will be described in detail with reference to the accompanying drawings.
第 1 図図示の如 く 、 戦斗車両等の構造物の外装材 と な る 主装甲板 1 の前面に所定の大 き さ の複合板 2 を多数連 続 し て取付用 ボル ト 3 で取付けて装甲板を構成す る 。 As shown in Fig. 1, a large number of composite plates 2 of a predetermined size are continuously attached to the front of a main armor plate 1 serving as an exterior material of a structure such as a fighter vehicle and attached with a mounting bolt 3. The armor plate.
前記複合板 2 は取付板 4 と 前面板 5 と の 間 に 中間板 6 を斜め に 間隔を置い て複数配設 し 、 そ の 瞵接す る 中間板 6 , 6 間 に充填材 7 を配設 し た も の であ り 、 前記取付板 4 は ァ ノレ ミ 、 プラ ス チ ッ ク 、 ゴム等の耐弾性能に劣 る 材 料よ り 成 り 、 前面板 5 と 中間板 6 と は耐弾鋼板な どの耐 弾性能に優れた材料よ り 成 り 、 充填材 7 はア ル ミ 、 ブラ ス チ ッ ク 、 ゴム 、 空気な ど耐弾性能に劣 る 材料よ り 成 つ
て い る 。 In the composite plate 2, a plurality of intermediate plates 6 are disposed at an oblique interval between the mounting plate 4 and the front plate 5, and a filler 7 is disposed between the adjacent intermediate plates 6 and 6. The mounting plate 4 is made of a material having inferior ballistic performance such as anoremi, plastic, rubber, etc., and the front plate 5 and the intermediate plate 6 are made of ballistic resistant material. Filler 7 is made of a material with poor ballistic performance, such as aluminum, plastic, rubber, air, etc. ing .
し か し て、 弾丸の運動エ ネ ルギは莫大な量であ る が方 向安定力 (直進維持力) は弾丸の 回転 ( ラ イ フ ル) に よ る コ リ オ リ の力又は翼に働 く 空気抵抗等であ り 、 速度ェ ネ ノレギ一 に比 し て微々 た る 値であ る 力、 ら 、 弾丸 1 0 は第 2 図 に示すよ う に斜めの面 1 1 に衝突す る と 弾丸の 直進 維持力 は大 き な抵抗を受け る こ と に な る 。 However, the bullet's kinetic energy is enormous, but the directional stability (straightness) is limited by the force or wing of the collider due to the rotation of the bullet (life). As a result, the bullet 10 impacts on the oblique surface 11 as shown in Fig. 2, because it is the air resistance that works and the force is a small value compared to the velocity energy. And the bullet's ability to keep straight is subject to great resistance.
こ の よ う であ る か ら 、 弾丸が複合板 2 の前面板 5 に衝 突す る と 前面板 5 を貫徹 し 、 そ の貫徹 し た弾丸は充填材 7 を難な く 貫い て中間板 6 に衝突す る が、 中間板 6 は斜 め と な っ て弾丸衝突方向 に対 し て角度があ り 、 かつ充填 材 7 よ り 硬い の で弾丸は充填材 7 の方向 に弾頭を向 け る と 同時に貫徹力が低下 し 、 弾丸は中間板 6 に よ っ て斜め に貫徹 し始め相 当大 き な運動エ ネ ルギを費や し 、 複合板 2 を貫徹 し た後に主装甲板 1 に斜め に衝突す る が、 そ の 弾丸の貫徹エネ ルギは大幅に低減 して い る ので弾丸は主 装甲板 1 を貫徹で き ずに飛散す る 。 As such, when the bullet collides with the front plate 5 of the composite plate 2, it penetrates the front plate 5, and the penetrated bullet penetrates the filler 7 without difficulty and passes through the intermediate plate. However, since the intermediate plate 6 is inclined and has an angle with respect to the bullet impact direction and is harder than the filler 7, the bullet faces the warhead in the direction of the filler 7. At the same time, the penetration force decreases, and the bullet starts to penetrate obliquely by the intermediate plate 6, spends a considerable amount of kinetic energy, and after penetrating the composite plate 2, the bullet enters the main armor plate 1. Although the vehicle collides obliquely, the energy that the bullet penetrates has been greatly reduced, so that the bullet cannot pierce the main armor plate 1 and scatters.
以上詳述 し た よ う に、 本発明 の装甲板に よ れば、 弾丸 は複合板 2 の 中間板 6 に角度を も っ て衝突す る か ら貫徹 力が低減 し 、 中間板 6 よ り も充填材 7 の貫徹抵抗力が小 さ い 力、 ら 弾丸の弾頭は充填材 7 に 向 う よ う に な り 、 弾丸 は複合板 2 を斜め に貫徹 し て運動エネ ルギを大幅に低減 し た後主装甲板 1 に衝突す る ので、 弾丸の主装甲板 1 を 貫徹す る エ ネ ルギは小 さ ぐ主装甲板 1 を貫徹す る こ と が
な い As described above in detail, according to the armor plate of the present invention, since the bullet collides with the intermediate plate 6 of the composite plate 2 at an angle, the penetration force is reduced, and the bullet is reduced. In addition, the penetration resistance of filler 7 is small, the warhead of the bullet is directed toward filler 7, and the bullet penetrates the composite plate 2 diagonally, greatly reducing kinetic energy. After hitting the main armor plate 1, the energy that penetrates the main armor plate 1 of the bullet can penetrate the smaller main armor plate 1. Absent
し たが っ て、 本発明の装甲板に よれば鋼板厚 さ を大 き く し た り 、 高価な材料を用 いずに耐弾性能を飛躍的 に向 上で き る 。
Therefore, according to the armor plate of the present invention, the thickness of the steel plate can be increased and the bulletproof performance can be drastically improved without using expensive materials.
