Abstract: An armor-penetrating ammunition assembly is provided with a multiple segment aluminum protective cap 26. The cap 26 is provided with a plurality of stiffening ribs 34, 34', 35, 35', and torque resisting tabs 40, 40' which rest in one of the grooves 37, 37' defined by the ribs 34, 34'. Additional stiffening is provided by rolled stiffening portions 36, 36' at the trailing end 32 of cap 28 and by longitudinal ribs 38, 38' at the longitudinal edges of each segment 28, 28' of the cap 26. Attachment structure is provided for forming a fixed interconnection between each segment 28, 28' of the cap 26 and a corresponding portion 19, 19' of the sabot 18. Thus, each segment 28, 28' of the cap 26 remains attached to a corresponding sabot portion 19, 19' as each portion 19, 19' of the sabot 18 separates from the penetrator 12 at muzzle exit without disturbing the flight of the penetrator 12.

Abstract: An armor-penetrating projectile assembly 10 is provided with a molded protective cap 28. The cap 28, which is preferably molded from Nylon 6/6, is provided with a plurality of longitudinal stress grooves 34 formed in the interior surface of the cap 28 for aiding cap break-up as the projectile assembly 10 exits the muzzle of a cannon, and with an integral centering band 32 for ensuring a desired fit of the projectile assembly 10 inbore and, to control the angular velocity of the cap 28 about its axis of symmetry 46 for better separation after being fired. The cap 28 is fastened to the sabot 18 of the projectile assembly 10 by means of a grooved extension 36 on the sabot 18 within which a plurality of ramped projections 38 of cap 28 are received. The ramped projections 38 are molded into the inner surface of the cap 28 aft of each window 40.

Abstract: A safe jettison device for aircraft stores is used to avoid unintentional ming of aircraft stores when they are jettisoned vice intentionally dropped. A coil is inserted in a conduit which prevents removal of the arming line unless the coil is skewed by a preset pulling force. If the store is released without skewing of the coil, the coil remains in the conduit and does not permit the arming line to be initiated. An activation device is held to the aircraft by a force less than the force needed to pull the coil free until an arming signal is given. Once an arming signal is given, the activation device holds with a greater force than that needed to pull the coil free.

Abstract: In a munition comprising a cartridge case, a subcaliber penetrator, and a ltipartite sabot for enabling propulsive discharge of said penetrator from said case, the improvement which comprises a film of curable sealant deposited on said sabot and said penetrator so as to prevent passage of propulsion gases between the parts of said sabot, and between the sabot and the penetrator.
