On impact the primer (37) is struck by the point (33) and transmits the ignition to an explosive column (14) located in the hollow nose (4).

On impact the primer (37) is struck by the point (33) and transmits the ignition to an explosive column (14) located in the hollow nose (4). The splinters from a metal closing piece (17) are then thrown violently into an empty duct (19) located along the center line of the high-explosive filling (23, 24) made of stabilized secondary explosive material. When the projectile has been fired it is driven in rotation in order to stabilize it and the bolt (27) subjected to centrifugal force frees the way along the duct (19). The splinters from piece (17) can therefore travel through the duct (19) and strike the ignition booster (22) which is also made of stabilized secondary explosive material. The hollow charge is formed by the conical piece (11). A highly effective projectile is produced having great operational safety.

An armour-piercing high-explosive projectile comprising a body portion attached to a cartridge case, a nose portion including a nose fuse affixed to said body portion and means on said body portion for engaging a rifled gun barrel and stabilizing the gyration of said projectile after said projectile has been fired, said body portion defining an inner chamber containing a secondary stabilized explosive material mounted about an empty duct having a forward end and a rearward open end, said inner chamber having its end closest to said nose portion defined by a slightly conical liner element forming a flat charge, said liner element having a central opening receiving said forward open end of said duct, said rearward open end of said duct communicating with said secondary explosive material, centrifugal safety means within said duct for blocking passage of solid particles through said duct before firing of the projectile, said nose portion enclosing along its longitudinal axis a hollow tubular sheath element having a forward open end and a rearward end fitted with a metal closing element, said hollow tubular sheath being fitted with a secondary stabilized explosive material in contact with said metal closing element and forming an explosive column, said explosive column being in axial alignment with said empty duct and having its rearward end near the forwrad end of said duct, said metal closing element having a concave surface facing said forward open end of said duct, said nose fuse comprising a primer of primary explosive material within said tubular sheath whereby pieces of said metal closing element are thrown through said duct and impact said stabilized explosive material contained in said inner chamber causing said material to explode, said centrifugal safety means unblocking said duct due to centrifugal force applied to said safety means.
