Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
Hollow charge warhead having a tubular casing, a conical liner, an explosive charge, a deflector embedded into said charge and a pin-point detonator, wherein: a. the deflector is frusto-conical in shape, the large basic of which faces said liner and the small basis of which faces said detonator; b. the axis of the conical liner, the deflector and the pinpoint detonator are coaxial; c. a pin-point transfer passage is provided between said detonator and said deflector; d. at least the connecting surface between the conical surface and the large basis of said deflector is curved, the radius of curvature being at least equal to the shortest distance between said deflector and the inner surface of said casing; e. the axial length of said deflector is at least equal to one fourth of the outer diameter of said casing; and f. the inner surface of said casing has a conical portion facing and partly surrounding said deflector.
Claim 2
Dependent Claim
156 words
Hollow charge warhead having a tubular casing, a conical liner, an explosive charge, a deflector embedded into said charge and a pin-point detonator, wherein: a. the deflector is frusto-conical in shape, the large basic of which faces said liner and the small basis of which faces said detonator; b. the axis of the conical liner, the deflector and the pinpoint detonator are coaxial; c. a pin-point transfer passage is provided between said detonator and said deflector; d. at least the connecting surface between the conical surface and the large basis of said deflector is curved, the radius of curvature being at least equal to the shortest distance between said deflector and the inner surface of said casing; e. the axial length of said deflector is at least equal to one fourth of the outer diameter of said casing; and f. the inner surface of said casing has a conical portion facing and partly surrounding said deflector.
Claim 3
Dependent Claim
33 words
Hollow charge warhead according to claim 1, wherein the shortest distance between said deflector and the inner surface of said casing is equal to approximately one-fifteenth of the inner diameter of said casing.
Claim 4
Dependent Claim
37 words
Hollow charge warhead according to claim 1, wherein the intersection circle of the conical surface and the plane of the large basis of said deflector lies with the cylindrical surface of the inner wall of said casing.
Claim 5
Dependent Claim
36 words
Hollow charge warhead according to claim 1, wherein the distance between the large basis of said deflector and the apex of said conical liner is at least equal to half the outer diameter of said casing.
Claim 6
Dependent Claim
29 words
Hollow charge warhead according to claim 1, wherein the axial length of said deflector is comprised between half the inner diameter and half the outer diameter of said casing.
Claim 7
Dependent Claim
37 words
Hollow charge warhead according to claim 1, wherein said pin-point detonator is housed in a metal case having a cylindrical section extended by frusto-conical section, the latter being seated in a corresponding recess of said explosive charge.
