Description
【発明の詳細な説明】 本発明は弾薬、特にらせん溝付きもしくはなしの小型の武器に使用される弾丸に 関するものである。[Detailed description of the invention] The invention relates to ammunition, particularly bullets used in small arms with or without helical grooves. It is related to
先願のE P −A −0129777は、発射薬を充填したケーシングと、外 周上に全長に亘り長さ方向の軸のまわりにらせん状に巻くようにあるいは軸に平 行に延びるように設けられた複数の溝をもった、銃口とほぼ等しい径を有する銃 弾と、銃弾を受容し、該銃弾を前記ケーシング内にシールする弾底板とからなる 弾丸を開示している。前記弾底板は、少なくとも一部に前記銃弾の径より大きい 径の部分を有し、ここに銃弾の前記各溝に係合して銃弾が発射される銃身に設け られたライフル溝に係合することにより弾底板自身が回転して銃弾を回転させる ための複数の突起を存している。The earlier application EP-A-0129777 has a casing filled with propellant and an outer shell. Circumferentially, over the entire length, spirally wrapped around the longitudinal axis or flat on the axis. A gun with a diameter approximately equal to the muzzle, with multiple grooves extending in rows. consisting of a bullet and a bullet bottom plate that receives the bullet and seals the bullet within the casing. Disclosing bullets. The bullet bottom plate has at least a portion larger in diameter than the bullet. A diameter portion is provided in the barrel of the gun which engages with each of the grooves of the bullet to cause the bullet to be fired. By engaging with the rifle groove, the bullet bottom plate itself rotates, causing the bullet to rotate. There are multiple protrusions for this purpose.
またこの先願には、らせん溝のない銃身用の、これに類似した弾丸も開示されて いる。This prior application also discloses a similar bullet for barrels without spiral grooves. There is.
このような弾丸は満足のゆくものではあるが、使用される状況によっては弾底板 と銃身との間のシーリングに改良が望まれる。Although these bullets are satisfactory, depending on the situation in which they are used, the bottom plate Improvements are desired in the sealing between the gun and the barrel.
したがって本発明によれば、銃弾と、この銃弾の後部に装着され、銃身の中でこ の銃弾の後方において銃弾の発射により膨張する気体をシールする銃底板とから なる弾丸において、前記銃弾は後方にテーバのついた円錐形突部を有し、銃底弾 はこれに適合するテーバのついた円錐形の凹部を有し、凹部の円錐頂角が突部の 円錐頂角でより大きくなっている。Therefore, according to the invention, a bullet and a from the gun bottom plate that seals the gas that expands when the bullet is fired behind the bullet. In the bullet, the bullet has a tapered conical protrusion at the rear, and the bullet has a tapered conical protrusion at the rear. has a tapered conical recess that fits this, and the conical apex angle of the recess is the same as that of the protrusion. It is larger at the cone apex angle.
好ましくは、この銃弾は先願のE P −A −0129777に記載された形 式を有し、銃弾は銃底弾から銃弾に機械的に回転を伝達するために銃底弾上の突 起と係合するらせん状または平行の溝を有する一方、従来の銃弾や銃底弾の形状 に適用されるものであるのがよい。Preferably, the bullet is of the type described in earlier application EP-A-0129777. The bullet has a protrusion on the bottom bullet to mechanically transmit rotation from the bottom bullet to the bullet. It has a spiral or parallel groove that engages the shaft, while the shape of a traditional bullet or gunshot It is preferable that it be applied to
銃弾と銃底弾に頂角の異なる互いに適合する部分を設けることにより、銃弾の円 錐形の突部に対し銃底弾が相対的に軸方向に摺動することによって引き起こされ る膨張する気体の作用の下で、銃底弾の膨張は銃底弾の円筒形の周面の全長に亘 って均一に分布する。突部の頂角と凹部の頂角が同じであると、上記膨張が均一 ならず、その結果気体のシールが不十分になることが見出された。これは凹部が 円錐形であるために生ずる銃底弾の壁厚の変化によるものである。By providing mutually compatible parts with different apex angles on the bullet and the bottom bullet, the circle of the bullet can be improved. This is caused by the axial sliding of the gun bottom bullet relative to the conical protrusion. Under the action of the expanding gas, the expansion of the bullet extends over the entire length of the cylindrical circumference of the bullet. It is evenly distributed. If the apex angle of the protrusion and the concave part are the same, the above expansion will be uniform. It has been found that this results in insufficient gas sealing. This is because the recess is This is due to the change in wall thickness of the gun bottom bullet due to its conical shape.
本発明による弾丸の一実施例を、以下添付の図面を参照して説明する。An embodiment of a bullet according to the present invention will be described below with reference to the accompanying drawings.
第1図はその弾丸の縦断面図、第2図は発射後の弾丸の形状を示す同様の図であ る。Figure 1 is a longitudinal cross-sectional view of the bullet, and Figure 2 is a similar diagram showing the shape of the bullet after firing. Ru.
第1図と第2図の両方において、弾丸のケーシングと弾丸が発射される銃の銃身 は明瞭のために図示を省略しである。In both Figures 1 and 2, the casing of the bullet and the barrel of the gun from which the bullet is fired. are not shown for clarity.
銃弾1はE P −A −0129777の第1〜5.6〜7、または12図に 示されたタイプのものであることか望ましい。Bullet 1 is shown in EP-A-0129777 No. 1-5.6-7 or Figure 12. Preferably of the type indicated.
銃弾1は頂角αの円錐形テーバを後方に有する後方突部2を有するように形成さ れており、これにより円錐面3を形成している。銃底弾4は好ましくはプラスチ ック製で、これに適合する円錐形の凹部5を有し、この円錐面6は前記突部2の テーバの角度αより大きい頂角βを有している。A bullet 1 is formed to have a rear protrusion 2 having a conical taper at the rear with an apex angle α. This forms a conical surface 3. The gun bottom bullet 4 is preferably plastic. It has a conical recess 5 that fits the conical surface 6 of the protrusion 2. It has an apex angle β that is larger than the Taber angle α.
銃底弾は好ましくは、先願のE P −A −0]、29777に記載されてい るように溝(図示せず)に係合する、前方に突出した突起7を有している。The gun bottom bullet is preferably as described in the earlier application EP-A-0], 29777. It has a forwardly projecting protrusion 7 which engages in a groove (not shown) so as to be oriented.
図示の実施例においては、突部の頂角は55°で銃底弾の頂角は60″である。In the illustrated embodiment, the apex angle of the protrusion is 55° and the apex angle of the bottom shot is 60''.
銃底弾4は弾丸の発射時に銃底弾の後面9に作用する気体の圧力により銃底弾の 前方への移動を許すための中央開孔8を有している。(第2図参照)銃底弾の四 部と銃弾の突部の頂角の相違により、発射の際銃底弾が銃弾の後部に対して圧縮 されたとき第2図に示されるように銃底弾の円筒状周面】0の全長に亘ってほぼ 均一な膨張11が生じる。The bottom bullet 4 is fired by the pressure of gas acting on the rear surface 9 of the bottom bullet when the bullet is fired. It has a central opening 8 to allow forward movement. (See Figure 2) Four bottom bullets Due to the difference in the apex angle of the protrusion of the bullet and the protrusion of the bullet, the bottom bullet is compressed against the rear of the bullet during firing. When the cylindrical circumferential surface of the gun bottom bullet is A uniform expansion 11 occurs.
