摘要： An explosive projectile which comprises a projectile body possessing a hollow compartment for receiving an explosive charge, a rear end surface, a border ring extending rearwardly from the rear end surface. A tracer composition sleeve is secured to the projectile body and possesses a front end surface which sealingly bears at the rear end surface of the projectile body. At least one of said rear end surface of the projectile body and said front end surface of the tracer composition sleeve having a substantially disc-shaped recess forming a substantially ring-shaped sealing contact surface between such rear and front end surfaces.

摘要： Up to now exceedingly precise manufacturing tolerances had to be observed in securing or mounting a flare composition or incandescent charge sleeve in a blind borehole in the tail portion of a projectile body to ensure reliable sealing against propellant gases. To prevent this disadvantage a bolt member or plug is inserted into the blind borehole of the projectile body until the face or end surface of this bolt member or plug abuts the bottom region or portion of the blind borehole. The bolt member or plug and the projectile body are rotated relative to one another. Due to friction between the end surface of the bolt member or plug and the bottom portion of the blind borehole sufficient heat is generated at the front end of the bolt member or plug such that material of this front end of the bolt member or plug flows into an annular groove of the blind borehole to form a flange member. This flange member securely anchors the bolt member or plug in the blind borehole. Then by appropriately machining the thus anchored bolt member or plug there can be formed the flare composition sleeve.
