Low-Temperature Lubricants for the M134Aircraft Machine Gun (Minigun).

摘要

Two lubricants,specifications MIL-L-14107(LAW) and MIL-L-46150(LSA-T),and two experimental lubricants, AWC No. 1and AWC No. 6were investigated. The weapon used for this investigation was the Minigun, 7.62MM,Automatic Gun GAU-2B/A. The purpose of the test was to determine which lubricant was suitable under sustained firing conditions at ambient temperature,at 0F, -30F,and -65F. Data were obtained concerning malfunctions,rate of fire,time to reach peak rate in seconds,oil applications,rounds fired,barrel temperature,and receiver temperature. It was found that LAW,the currently authorized low-temperature (0to -65F) lubricant for many weapons,could not be recommended at any temperature on the minigun. LSA-T performed better than either AWC No. 1or AWC No. 6at ambient temperature. At 0F no significant difference occurred between these three compounds. However,at -30F, AWC No. 1was superior to the other three. At -65F, AWC No. 1and AWC No. 6gave better performance than LSA-T. (Author)
