Abstract
A slug or billet of incendiary material is placed in a projectile body and oth are heated to a temperature at which the incendiary material can easily be formed. A deep drawn metal cup, formed in the shape of the desired explosive cavity, is rammed or forced into the projectile, displacing the incendiary material into the desired configuration and the assembly is then cooled leaving the metal cup in place.
Claims3
A method for producing cast in place incendiary liners in the explosive cavities of ordnance items wherein contact between the incendiary material and the explosive is precluded comprising the steps of:
- placing a slug of incendiary material within the cavity of the ordnance item;
- heating the ordnance item and incendiary material to a temperature at which the incendiary material may be easily formed;
- forcing a deep drawn metal cup into the cavity to displace the incendiary material into the desired liner configuration;
- and
- cooling the resulting configuration whereby the incendiary liner is mechanically and metallurgically bonded to both the ordnance item and said metal cup and the recess within said metal cup defines a cavity for the explosive load with intimate contact between the explosive load and said liner being prevented.
