Acoustic Tests on a New Motor Generator System for the Minuteman Launch ControlCenters at Alpha 01 and Sierra 00, Malmstrom AFB, Montana

摘要

Field tests of the acoustic performance of a new motor generator system (MGS)were performed at Minuteman Launch Control Centers (LCC) Alpha 01 and Sierra 00, Malmstrom AFB MT. This same MGS unit was accepted for use after the Hill Engineering Test Facilities (HETF) acoustic performance studies conducted in 1988. Rivet Mile from the Ogden ALC began installation of the new MGS at Malmstrom in the spring of 1990. Performance tests were requested by 00-ALC/MMGRMM, and SAC, to compare with the HETF data and document the LCC acoustic environment with the new MGS operating in a field setting. This report presents our findings.
