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 turbine generator will provide all shipboard 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 qualification 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 Virginia quarry. "There was no damage at all. No rework or redesign was necessary. That's very unusual for this type of equipment," said A1 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 economy.

The AG9130 generator sets are powered by Allison 501-K34 engines, a marine deriative of the U.S.

Navv's T56-A-427 turboprop en- gine. The T56 has been in production since the 1950s. The 501-K34 is the fourth generation version of this engine.

Allison Gas Turbine is division of General Motors and is based in Indianapolis, Ind.
