摘要： A method for converting mortar shells into shells for use in smooth-bore gun barrels having an interior surface. The mortar shells include a warhead having a front end, a rear end, a tail fin, and a propellant charge. A guide casing is attached to at least the rear end of the warhead. The guide casing includes an outside surface. The guide casing supports at least the rear end of the warhead and is adapted for use with the smooth-bore gun barrel that the converted shells are to be fired from. A bourrelet is attached to the outside surface of the guide casing for sealing between the converted shells and the interior surface of the smooth-bore gun barrel that the converted shells are to be fired from.

摘要： The invention relates to a drive element (1) for a sub-calibre spinning projectile (2). The drive element (1) comprises an annular sabot member (17) applied on the rear part of the projectile (2) and a guiding sleeve (7) of full-calibre substantially embracing the projectile (2) as well as the sabot member (17). The guiding sleeve (7) is provided with an external driving band (9) made directly in the sleeve material and internal threads coacting with corresponding threads (18) of the sabot member (17). The front part of the sabot member is provided with a central, axial hollow (20) for the rear part of the projectile comprising a plurality of axially extending locking pins (22) arranged to engage corresponding recesses (6) made in the outer cylindrical surface of the projectile close to its rear end surface (5) to secure the projectile (2) to the sabot member (17). The guiding sleeve is made of a high-strength material of low density, preferably a glass-fibre reinforced polyamide.
摘要翻译：本发明涉及一种用于副口径旋转射弹（2）的驱动元件（1）。驱动元件（1）包括施加在射弹（2）的后部上的环形制动器构件（17）和基本上包围射弹（2）的全口径导向套筒（7）以及支架构件 17）。引导套筒（7）设置有直接在套筒材料中制成的外部驱动带（9），并与内部构件（17）的相应螺纹（18）共同作用。舷窗构件的前部设置有用于射弹后部的中心轴向空心（20），其包括多个轴向延伸的锁定销（22），所述多个轴向延伸的锁定销（22）设置成接合在外圆柱形表面中形成的相应凹部（6）靠近其后端表面（5）的弹丸以将射弹（2）固定到膛体构件（17）。引导套筒由低密度的高强度材料制成，优选玻璃纤维增强聚酰胺。
