Incendiary composition for a fin-stabilized kinetic energy projectile

Abstract

An incendiary composition ( 14 ) for a fin-stabilized kinetic energy projectile ( 1 ) which can be arranged in the tail region of the projectile ( 1 ) and, upon impact with a target ( 13 ), penetrates the target ( 13 ) as a separate unit behind the penetrator ( 2 ) of the kinetic energy projectile ( 1 ). To reach the objective of a high destructive effect caused by the incendiary composition ( 14 ) within a target ( 13 ), despite a small volume and a low mass, and to ensure that the incendiary composition is ignited securely by the shock waves generated upon impact, according to the invention, a titanium sponge is used as the incendiary composition ( 14 ), with an epoxide resin or a polyester resin used as a binder.
