Warhead casings and methods of manufacture

摘要

A warhead casing includes a nose region, a tail region, a tubular body region, and a central cavity extending along a lengthwise axis and having a first axial end and a second axial end. An aft wall is formed integrally with the tail region and extends radially toward the lengthwise axis to define the second end of the central cavity, and includes an aperture configured to receive a fuse device. A method of manufacturing a warhead casing includes forming a nose portion, a body portion, and a tail portion. The tail portion includes a circumferential outer wall defining an inner cavity, and an aft wall integrally formed with the circumferential outer wall and extending radially inward to define an axial end of the inner cavity. At least one of the nose portion or the tail portion is joined to the body portion.

1. A warhead casing, comprising:
a nose region, a tail region, and a tubular body region therebetween, the regions defining a lengthwise axis of the casing; a central cavity extending along the lengthwise axis and having a first axial end and a second axial end, the central cavity having a diameter and being defined within circumferential outer walls of the nose, tail, and tubular body regions; an aft wall formed integrally with the tail region and extending radially toward the lengthwise axis to define the second end of the central cavity, whereby the aft wall remains integral with the tail portion when the casing expands radially upon impact and before detonation, the aft wall including an aperture configured to receive a fuse device and extending axially through the aft wall, the aperture having a diameter that is no more than half the diameter of the central cavity in the tail region.
