Low-Temperature Lubricants for the M134 Aircraft Machine Gun (Minigun)

Abstract

Two lubricants, specifications MIL-L-14107(LAW) and MIL-L-46150(LSA- T), and two experimental lubricants, AWC No. 1 and AWC No. 6 were 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 (0 to -65F) lubricant for many weapons, could not be recommended at any temperature on the minigun. LSA-T performed better than either AWC No. 1 or AWC No. 6 at ambient temperature. At 0F no significant difference occurred between these three compounds. However, at -30F, AWC No. 1 was superior to the other three. At -65F, AWC No. 1 and AWC No. 6 gave better performance than LSA- T.
