    • PROBLEM TO BE SOLVED: To provide a device for hardening mechanical propulsion system connection for a mortar shell, and the shell including such connection.SOLUTION: A self-propelled munition intended to be fired against a target, comprises: a munition 10 having a munition rear body 50 of circular cylindrical shape of diameter D1, along a longitudinal axis ZZ', a propulsion system 20 of the munition having a casing 30 in the form of a tube of circular cross section, of axis of revolution coincident with the longitudinal axis ZZ'. The casing 30 has an internal surface 31 of the same diameter D1 as the munition rear body 50, being able to slide over the munition rear body 50. The casing 30 contains a pyrotechnic propulsion chamber 33 intended to be activated upon firing. The munition comprises a first mechanical connection comprising several shear pins 70, evenly distributed about the longitudinal axis ZZ', and a second mechanical connection having a ring groove 56 around the munition rear body 50, another ring groove 90 on the internal surface 31 of the propulsion system casing, and a retaining ring 58.
    • 要解决的问题:提供一种用于硬化用于迫击炮弹的机械推进系统连接的装置,以及包括这种连接的壳体。 解决方案:一种旨在对准目标射击的自行式弹药,包括:弹药10,其具有直径为D1的圆柱形形状的弹道后体50沿着纵向轴线ZZ',推进系统20 具有与纵向轴线ZZ'重合的旋转轴线的圆形截面管形式的壳体30的弹药。 壳体30具有与弹药后体50相同的直径D1的内表面31,能够在弹药后体50上滑动。壳体30包含旨在在燃烧时被激活的烟火推进室33。 弹药包括第一机械连接,其包括围绕纵向轴线ZZ'均匀分布的多个剪切销70,以及具有围绕弹药后主体50的环形槽56的第二机械连接,在内部表面31上的另一个环形槽90 推进系统外壳和保持环58.版权所有(C)2012,JPO&INPIT
