MEMORANDUM FOR AFSC/PZAAA

FROM: Johnny Mangum USAF AFMC AFLCMC/WIUED

SUBJECT: DC Generator PR 18-00164

Purpose is to identify potential sources of repair/overhaul for direct current generator used on US

Air Force TH-1H training helicopter; aircraft is a derivative of the legacy UH-1H “Huey”, and subject generator appeared on that aircraft and included with the TH-1H after conversion.

NOUN NSN P/N

Generator, Direct Current 6115-00-942-2094 30B37-37A

This requirement is for repair/overhaul services. Our services strategy is a five-year contract

(basic plus four option periods) and will continue through FY22. The projected quantities will be

Best Estimated Quantities (BEQ) of 4 per year. BEQ for the basic year is 15ea.

Generator; PN 30B37-37A, configuration and performance is IAW MIL-G-6162. Generator is used to generate the electrical power for 28-Volt aircraft electrical systems. This DC generator is a brush type rotating machine capable of delivering 30 Volts DC at rated current of 300 amperes, when driven at its rated speed (5000 rpm). The unit is self-cooled by means of an integral fan rotating with the output shaft. A terminal board is mounted on the housing to facilitate external connections. Slotted mounting holes are provided for ease of installation to aircraft engine.
