ABSTRACT:
A jettisoning cover for a munition arranged to be held against the end of a ring secured to the end of a munition which is fired at a high velocity through the atmosphere. The cover protects the contents of the munition from the high velocity through the atmosphere but is jettisoned after the velocity has slowed. The cover is held by two clips on the ring directed over the cover and a third clip on the cover engaging a notch in the ring. A detent mounted within a recess in the ring extending into a hole in the cover secures the cover in place.
The detent is secured by a shear pin through the detent and an adjacent slider in an arcuate channel. The slider is propelled by an explosive powered piston which shears the shear pin to release the cover. A spring from the cover is wrapped around the ring when the cover is attached and provides energy to jettison the cover when the cover is released.
