    • An safe and arm apparatus is disclosed wherein the apparatus utilizes setback acceleration for in-bore safety and sustained in-bore acceleration to position various members to allow for subsequent alignment of the firing train at arm time. The apparatus includes a rotor that houses an explosive lead and having a side bore hole formed therein which selectively interrupts the initiating explosive train both in front of and after the explosive train lead. The explosive interface between a detonator and a lead is unimpeded when the bore hole is in-line with a second corresponding hole in a protective cover. The rotor is normally secured by a setback lock and a shear tab. Upon launching from a gun, an in-bore lock (in conjunction with a retaining collar) moves down at a low acceleration level to additionally secure the rotor out-of-line while the projectile is in the gun tube. The movement of the in-bore lock also removes an impact drive surface for a piston actuator on the rotor, which eliminates the possibility of an in-bore-arming in the event of an inadvertent firing of the piston actuator. During the period in the gun tube, the setback lock also swings down under a predetermined high acceleration and causes the setback lock to latch, leaving the in-bore lock and a shear/break-away tab holding the rotor. Once out of the gun tube, the in-bore lock releases, leaving the rotor free (except for the shear tab which is overcome by the piston actuator) and restoring the impact drive surface of the piston actuator on the rotor. The electrically activated piston actuator is positioned to rotate and lock the rotor in line such that the detonator in the housing, the side bore hole in the rotor, the explosive lead in the rotor, and the bore hole in the cover are aligned for target initiated detonation. The piston actuator is controlled by an electronics assembly.
    • 公开了一种安全和手臂装置,其中该装置利用膛内安全性和持续的内膛加速度的遏制加速度来定位各种构件以允许随后在胳膊时间对准击发火车。 该装置包括容纳爆炸引线并具有形成在其中的侧孔的转子,其在爆炸火车线前后均选择性地中断起动爆炸火车。 当钻孔与保护盖中的第二个相应孔对齐时,雷管和引线之间的爆炸界面是不受阻碍的。 转子通常由挫折锁和剪切片固定。 在从枪上发射时,钻孔锁(与保持套环一起)以低加速度水平向下移动,以在炮弹位于枪管内时额外地固定转子。 内孔锁的运动还消除了转子上的活塞致动器的冲击驱动表面,这消除了在活塞致动器的无意烧毁的情况下进行内孔布防的可能性。 在枪管期间,挫折锁也在预定的高加速度下摆动下来,并引起挫折锁定,从而留下内孔锁和保持转子的剪切/分离片。 一旦离开枪管,钻孔锁释放,离开转子(除了由活塞致动器克服的剪切片除外)和恢复活塞致动器在转子上的冲击驱动表面。 电激活的活塞致动器被定位成使转子旋转并锁定,使得壳体中的雷管,转子中的侧孔,转子中的爆炸引线和盖中的钻孔对齐,用于目标发起 引爆 活塞致动器由电子组件控制。
