Abstract

A warhead nose comprises a conical/ogive body having an outer surface with a top circumference and base circumference, and ribs extending along the outer surface of the conical/ogive body tapering so that the circumference around the ribs is smaller than or equal to the circumference of the base, the warhead nose dimensions are determined by the following relations:

$E\le D,\frac{1}{5}D\le F\le 2D,G\le \frac{1}{5}D,\frac{1}{20}D\le H\le \frac{1}{2}D,I\le \frac{2}{5}D$
where,

• D is maximum nose diameter; E is external diameter of the ribs; F is length of the ribs along the nose; G is minimal width of the ribs; H is height of the rib protrusion; and I is the minimal width of the rib at the adjoining point with the nose.

Claims

1. A warhead nose comprising:

a flat or concave tip circumferential surface from which extends a conical/ogive body having an outer surface and a base circumference, and ribs extending from the circumference of the flat or concave tip along the outer surface of the conical/ogive body tapering downward towards the base, wherein the circumference around the ribs is larger than the circumference of the flat or concave tip and smaller than or equal to the circumference of the base, the warhead nose dimensions are determined by the following relations;

2. A warhead nose in accordance with claim 1, wherein the ribs are equidistantly spaced apart.

3. A warhead in accordance with claim 1, further comprising a boss extending from the flat or concave tip, the dimensions of which are determined by the following relations:

4. A warhead nose in accordance with claim 3, wherein the boss is either cylindrical and/or tapered.

5. A warhead comprising:

the nose of claim 1;

a main section which includes an explosive charge; and

an aft section which holds at least one penetration or initiation fuse.

6. A warhead comprising:

the nose of claim 1; and

a main section which includes a payload.

7. A warhead nose comprising:

a body comprising a cylindrical section and a conical/ogive section, an outer surface with a top circumference and base circumference, and ribs partially extending from the outer surface of the cylindrical section and partially from the conical section, wherein the circumference around the ribs is larger than the base circumference and the top circumference, the warhead nose dimensions are determined by the following relations;

8. A warhead in accordance with claim 7, further comprising a boss the dimensions of which are determined by the following relations:
