    • A hand operated projectile extractor to remove unspent projectiles from 155 mm howitzers, which extractor is generally cylindrical, about 18 inches in length, with a handle extending from the rear thereof and with an overall weight of at least about 30 pounds, to provide enough momentum to eject the projectile. When rammed into the muzzle of a howitzer and down the barrel thereof, the ogive of the projectile enters the open front of the extractor's cylindrical body and will be impacted by a compression ring along the extractor's front edge, which compression ring has a minimum internal diameter of 4.75 inches and is formed of particular flat and curved surfaces which will not bind to either the projectile or the barrel.
    • 一种手动的抛射物提取器,用于从155毫米榴弹炮中除去未使用的弹丸,该拔出器通常为圆柱形,长度约为18英寸,手柄从后部延伸,总重量至少约30磅,以提供足够的动量 弹射弹药。 当撞击榴弹炮的枪口并沿着枪管枪弹时,射弹的弹头进入提取器的圆筒体的开口前部,并沿着拔出器的前边缘被压缩环冲击,该压缩环的最小内径 为4.75英寸,由特殊的平坦和弯曲的表面形成,这些表面不会与射弹或枪管结合。

    • A stabilizing fin deployment apparatus may include a base assembly for attachment to the rear end of a projectile. The base assembly may include a base, a spacer, a fin mount, a gas cavity and an opening that extends from the rear end of the base to the gas cavity. A retention nut may engage the base and secure the fin mount and spacer to the base. A retention plug may be disposed in the opening in the base assembly. The retention plug may include at least one gas conduit between an outer surface of the retention plug and the gas cavity. A retention bolt may extend through the retention plug and may be fixed to the base. A plurality of fins hubs may be rotatably fixed to the base. A plurality of fins may be translatably connected to the fin hubs. When deployed, the fin hubs may rotate forward and the fins may translate outward far into the airstream.
    • 稳定翅片展开装置可以包括用于附接到射弹的后端的基座组件。 基座组件可以包括底座,间隔件,翅片安装件,气体腔和从底座的后端延伸到气腔的开口。 保持螺母可以接合基座并将翅片安装件和间隔件固定到基座上。 保持塞可以设置在基座组件的开口中。 保持塞可以包括在保持塞的外表面和气体腔之间的至少一个气体导管。 保持螺栓可以延伸穿过保持塞并且可以固定到基座。 多个翅片毂可以可旋转地固定到基座。 多个翅片可以可平移地连接到翅片毂。 当部署时,翅片毂可以向前旋转,并且翅片可以向外远远地转换成空气流。
