Abstract
Abstract An explosive missile or projectile assembly which possesses a projectile body and a ballistic hood which is positioned in front of the projectile body, wherein the hood encompasses a head end portion of the projectile body, and which includes an explosive charge arranged within the projectile body and a base detonator. An in-depth effect and fragmentation effect comes into bearing in the direction of firing, in that fragments are arranged intermediate the head end portion of the projectile body and the ballistic hood, and in which the projectile body is equipped with performed fragments.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
152 words
Explosive projectile assembly including a projectile body and a hollow ballistic hood mounted in front of the projectile body; a head end portion of the projectile body being encompassed by said hood; said head end portion having a forwardly extending conical configuration protruding into the interior of said hood; an explosive charge being arranged within said projectile body; a base detonator attached to a tail end of said projectile body; a multiplicity of first preformed fragments embedded in a matrix of a polyurethane foam material being arranged intermediate the head end portion of said projectile body and the ballistic hood so as to at least fill an annulus in the interior of said hood formed intermediate the outer surface of the conical head end portion of the projectile body and the inner wall surface of said hood; and further preformed fragments being embedded in a peripheral wall surface of said projectile body.
Claim 2
Dependent Claim
152 words
Explosive projectile assembly including a projectile body and a hollow ballistic hood mounted in front of the projectile body; a head end portion of the projectile body being encompassed by said hood; said head end portion having a forwardly extending conical configuration protruding into the interior of said hood; an explosive charge being arranged within said projectile body; a base detonator attached to a tail end of said projectile body; a multiplicity of first preformed fragments embedded in a matrix of a polyurethane foam material being arranged intermediate the head end portion of said projectile body and the ballistic hood so as to at least fill an annulus in the interior of said hood formed intermediate the outer surface of the conical head end portion of the projectile body and the inner wall surface of said hood; and further preformed fragments being embedded in a peripheral wall surface of said projectile body.
Claim 3
Dependent Claim
71 words
Explosive projectile as claimed in claim 1, wherein said conical head end portion of said projectile body includes a cylindrical extension protruding into said hood, said first preformed fragments embedded in said matrix forming a fragmentation member having a central cutout conforming to the shape of the head end portion of the projectile body facing said hood and an external shape conforming to the internal wall structure of said ballistic hood.
Claim 4
Dependent Claim
20 words
Fragmentation member for a projectile assembly as claimed in claim 2, wherein said fragmentation member is a generally frusto-conical member.
Claim 5
Dependent Claim
53 words
Fragmentation member as claimed in claim 3, wherein said fragmentation member has a planar end surface facing the interior space of said hollow ballistic hood; and a foamed plastic material body in front of said fragmentation member being arranged in said hood and contacting against said planar end surface of said fragmentation member.
Claim 6
Dependent Claim
63 words
Fragmentation member for a subcaliber projectile assembly as claimed in claim 3, wherein said projectile body has a closed conical end extending into said hollow ballistic hood, said fragmentation member encompassing said conical end and being of a height extending beyond the conical end portion of said projectile body into the interior of said hood by approximately 30% of the external diameter thereof.
Claim 7
Dependent Claim
33 words
Fragmentation member as claimed in claim 5, wherein the conical end portion of the projectile body includes a central cylindrical section having a conical tip, and said cylindrical section protrudes into the hood.
Claim 8
Dependent Claim
24 words
Fragmentation member as claimed in claim 6, wherein the conical tip of said cylindrical section projects outwardly of the fragmentation member into said hood.
Claim 9
Dependent Claim
15 words
Fragmentation member as claimed in claim 1, wherein the projectile assembly comprises a full-caliber projectile.
Claim 10
Dependent Claim
15 words
Fragmentation member as claimed in claim 1, wherein the projectile assembly comprises a sub-caliber projectile.
Claim 11
Dependent Claim
36 words
Fragmentation member as claimed in claim 4, wherein the ballistic hood possesses a heavier wall thickness in the region containing the fragmentation member than the wall thickness in the region containing the foamed plastic material body.
Claim 12
Dependent Claim
15 words
Fragmentation member as claimed in claim 1, wherein said ballistic hood is constituted of steel.
Claim 13
Dependent Claim
50 words
Fragmentation member as claimed in claim 1, wherein said first preformed fragments form a fragmentation member of a reducing cross-section within said ballistic hood extending in the direction of firing of said projectile assembly, and a plastic material body being arranged in said hood in front of said fragmentation member.
