TEMPERATURE SENSITIVITY OF THE T324E22 VIGILANTE HE CARTRIDGE-GUN SYSTEM
Abstract
Heat tests were made with the individual components and the complete T324E22 HE cartridges. Results of these tests indicate that the T28E1 propellant has the lowest cook-off temperature, 239F. The next lowest was the T300 base fuze tetryl booster lead with a temperature of 275F. Of four cook-off tests conducted with a complete HE loaded T324E22 cartridge, the lowest cook-off temperature recorded was 262F when the round in gun barrel was not preheated. Results of gun firing tests of the 37mm T324E22 cartridge containing live propellant and inert HE systems were compared with results of static cook-off tests. These results indicated that the lowest temperature recorded before cook-off occurred was 237F at the cartridge case area. This temperature was achieved with seven 48-round bursts and was 2F below the cook-off temperature of the T28E1 propellant. At nine bursts the temperature in the same area was 250F. The explosive MAX-2 had a cook-off temperature of 385F when it was tested. The temperature of the area in the gun where the explosive was located after firing seven 48-bursts was 311F maximum. After nine such bursts the temperature increased to 395F.
