Abstract:
Two 8-inch rocket-assisted XM650E4 projectiles were fired at Yuma Proving Ground, during June 1976, to determine interior temperature of the warhead. The temperature sensors were located on the interior wall of the warhead base. The projectiles were also instrumented with trisondes to determine their flight behavior. One of the rounds, fired at Zone 9 from the M110A1 weapon, did not transmit any data. TR 296, which was fired from the M110 at Zone 7, transmitted both the temperature and trisonde data. Flight data from the trisonde show a well-behaved projectile. The data from the temperature sensors of TR 296 indicate that there is a 35-second time lag between the ignition of the rocket motor and the start of bulkhead temperature rise. Data also show a uniform bulkhead temperature at the start and conclusion of the flight with no indication of hot spots. The total temperature rise for the bulkhead was about 8 C, reaching a level of 32 C at impact.
