PROPULSION UPDATE First Allison Gas Turbine Genset Shipped For DDG-51 Installation Genset Performs Well In Shock Tests The first of Allison Gas Turbine's new generator sets has been shipped to Bath Iron Works, Bath, Maine, for installation in the lead ship of the U.S. Navy's Arleigh Burke (DDG-51) Class destroyers. The model AG9130 ship service gas tur- bine generator will provide all ship- board electrical power on the new destroyers. The generator set is a result of a design and production contract with Bath Iron Works. The U.S. Navy contracted with Bath Iron Works in 1985 to design and construct the lead ship in the Arleigh Burke Class. Allison and Bath have an agreement for the generator sets for the follow ships. The shipment to BIW follows the successful completion of qualifica- tion tests on the generator set. One of the most stringent, the shock test, was passed in June 1988. The generator set was subjected to 60 pound dynamite charges at four different ranges during float barge testing in an abandoned Vir- ginia quarry. "There was no damage at all. No rework or redesign was necessary. That's very unusual for this type of equipment," said A1 An Allison Gas Turbine generator set, model AG9130, such as the one shown, will provide all shipboard electrical power for the new Arleigh Burke Class destroyers. Wells, manager of marine sales at Allison. The generator set incorporates a redesigned Allison engine capable of producing up to 3,000 kilowatts of electrical power on a 100-degree day with 12 percent improved fuel econ- omy. The AG9130 generator sets are powered by Allison 501-K34 en- gines, a marine deriative of the U.S. Navv's T56-A-427 turboprop en- Shipshape in 15 seconds.
