    • A fuse is used in a spin-type projectile. A percussion cap is mounted in a rotor which is normally disposed in a safety position. Rotation of the rotor to a firing position wherein the percussion cap is aligned with a firing pin is prevented by two independently operating safety devices prior to firing of the projectile. A first safety device comprises a conventional centrifugal mechanism which normally holds a bush within a recess of the rotor but releases same when the projectile spins. A second safety device comprises the firing pin which is urged into engagement with the rotor recess by a spring. An inertia disk is moved, in response to spinning of the projectile, to a position holding the firing pin out of engagement with the rotor recess. This enables the rotor to rotate to its firing position. When the projectile spin slows down or when the projectile impacts the target, the inertia disk can be moved aside as the firing pin enters the percussion cap.
    • 在旋转式抛射体中使用保险丝。 敲击帽安装在通常设置在安全位置的转子中。 通过两个独立操作的安全装置在撞击射弹之前,将转子旋转到击打位置,其中冲击帽与撞针对准。 第一安全装置包括常规的离心机构,其通常将衬套保持在转子的凹部内,但是当弹丸旋转时将其释放。 第二安全装置包括通过弹簧推动与转子凹部接合的撞针。 响应于弹丸的旋转,惯性盘被移动到保持撞针的位置脱离与转子凹部的接合。 这使得转子能够旋转到其点火位置。 当抛射体旋转减速时或当弹丸撞击目标时,随着撞针进入冲击盖,惯性盘可以移动到一边。
