ABSTRACT:
A non-ablative heat sensitive nose cap uses a highly conductive solid ford ogive and rear segmented ogive member, in contact with a low melting point locking ring which is thermally isolated from the main projectile body. The locking ring holds the rear ogive segments together until the desired time for projectile-break. Break-up occurs when a zinc alloy locking ring fails under the combined influence of decreasing yield strength and centrifugal force due to launch and free flight imposed spin.
