Abstract

A projectile is provided for penetration into targets of both slight and great resistance to penetration. The projectile is also operative for exploding the payload of the projectile after penetration. The projectile includes a forward barrier of high strength material and a fuse adapted to be detonated on impact with targets. This fuse operates with high sensitivity on impact with targets of slight resistance to penetration and by delayed action which permits explosion of the payload of the projectile after penetration. A delayed action charge included in the fuse is placed behind the barrier and is allocated a protected position where shock waves which occur in the forward material portions of the projectile are prevented from triggering or actuating the delayed action charge. The delayed action charge is exposed to a unit placed between the barrier and the delayed action charge, the unit, when the fuse is detonated, effectuating a reliable ignition of the delayed action charge.

Dependent claims

A high velocity projectile for penetration of both soft and hard targets and exploding the payload after penetration comprising:

forward and rear portions of a projectile body;
a barrier member made of a high strength material separating said forward and said rear portions, said rear portion including a casing member;
a fuse detonatable on impact with a target and operating either by high sensitivity on impact against soft targets or by delayed action, which allows explosion of the main charge after penetration, said fuse including a delayed action charge, located in said rear portion of said projectile body behind said barrier member thereby being protected against detonation by shock waves produced in the forward portion, said charge being disposed in a hollow cylindrical portion which is resiliently mounted within said casing member by means of elastic annular ring members damping movements of said cylindrical portion in both axial and radial direction;
and
an effectuating unit disposed between said barrier and said delayed action charge for providing a reliable ignition of said delayed action charge in the detonated state of said projectile.
