摘要： The present invention relates to a firearm projectile capable of releasing a secondary payload mid-flight through a pyrotechnic timing mechanism. Once the firearm is fired, the powder in the casing pushes out the projectile as a typical round. In addition, the powder ignites the delay column. The formulation and amount of delay pyrotechnics determines the delay time. When the delay column is burned, the final portion ignites an expelling charge. The expelling charge builds pressure in the projectile casing and separates the base plug from the main projectile housing. The expelling assembly pushes out the secondary payload out the rear of the projectile. Although the payload exits the rear of the projectile at minimum velocity, the net velocity of the payload is still in the forward direction.

摘要： The present invention relates to a substantially spheroidal fragmentation device (10). The fragmentation device (10) comprises: i) a protective exterior layer (6) of resilient material accommodating at least one warhead (9); ii) an inner core (11) protected by said exterior layer (6). The inner core (11) comprises: ii.a) an insensitive munition (IM); ii.b) a polymeric, plastic and/or rubbery matrix embedding the insensitive munition (IM); ii.c) explosive material (5) enclosed within the matrix of ii.b) and/or surrounding the matrix of ii.b). The ratio of the thickness of the protective exterior layer (6) to the radius of the fragmentation device (10) ranges from 0.1:1 to 0.7:1. The warhead (9) is accommodated within the protective exterior layer (6) or between the inner core (11) and the protective exterior layer (6). The invention also relates to a method of firing a fragmentation device (10) as disclosed herein, wherein a firearm is aimed at a surface enabling rebounding of the fragmentation device (10) whereby the fragmentation device (10) changes direction. The invention also relates to the use of a fragmentation device (10) as disclosed herein in a firearm.

摘要： A warhead includes an outer casing and an inner shell, which delimits a central space for an explosive substance. The inner shell receives a series of preformed elements, which are arranged in contact with the outer side of the inner shell. The inner shell is arranged for a controlled fragmentation upon a detonation of the explosive substance. The preformed elements are arranged with a surface contact against the inner shell.

摘要： A fragmentation warhead is provided, capable of being mounted in a carrier vehicle, the warhead having a longitudinal axis. In at least one example the warhead includes a shell that extends along the longitudinal axis. The shell includes a fixed shell portion and a fragmentation portion, and defines therebetween a cavity for accommodating therein an explosive charge. The fragmentation portion includes at least one set of serially adjacent fragments in correspondingly serially contiguous relationship in the fragmentation portion and in generally helical relationship with respect to the longitudinal axis. A corresponding carrier vehicle and a corresponding missile are also provided.

摘要： The invention relates to a shell (4) intended to be placed around a fragment-generating body (2) of an ammunition (1). This shell is characterized in that it comprises an inner wall (9) having a geometry such that it can be positioned with shape matching with that of the body (2) on which it is intended to be fastened, the inner wall (9) bearing cells (11) having a profile with a closed contour secured to the wall (9) by a first end, the cells (11) not being adjoining, therefore separate from one another, all the way around their contour by a non-nil distance (d).
The invention also relates to an explosive ammunition including such a shell.

摘要： A method of making a fragmenting structure for an explosive device includes placing a volume of fragments of a deformable metal material into a press mold, the fragments having sufficient surface adhesiveness to adhere to each other upon being compressed together, e.g., by coating the fragments with adhesive. The fragments are compressed together in the press mold to form the fragmenting structure as a rigid and substantially void-free structure of compression-deformed, mutually adhering metal fragments, the fragmenting structure being sized and shaped for subsequent incorporation into the explosive device. An explosive device includes an explosive charge and a fragmenting structure adjacent to the explosive charge, the fragmenting structure being a rigid and substantially void-free structure of compression-deformed, mutually adhering metal fragments. The structure may have been manufactured by the disclosed method.
