On March 13th, the Martin

Marietta team—including Cegelec,

Gibbs & Cox, General Electric Cor- porate Research, Bath Iron Works and Ingalls Shipyard, plus several engineering firms — signed a $50 million contract with the U.S. Navy to design the fleet of the future.

The philosophy behind the new design represents a revolutionary change in military practice. The specifications were simple; design a common Integrated Power Sys- tem for both ship's electrical ser- vice and electric propulsion for use throughout the entire surface fleet, aircraft carriers to amphibs.

Unlike previous contracts and vessel designs, MM's Integrated

Power System proposal was selected not for its high-tech, military ex- clusivity, but rather for its low-risk design utilizing proven marine elec- tric propulsion technologies that function equally well for both go- ernment and commercial fleets.

As a major player on the Marti

Marietta team, Cegelec will supp] the propulsion system component generators, motors, converters an switchgear. Cegelec was formed i 1989 by the merger of Britain's GE and CGEE Alsthom of France i 1989. The company recently a> quired a controlling interest in AE( the German drive manufacture

This new corporate configuratioi according to Cegelec, makes the con pany the largest drive manufacture in the world — and therefore a obvious choice to join the MM tean

Integrated Power System

Advanced Development

The approach is to use commei cially-proven equipment and a zom

DC ship service distribution arch tecture combined with a solid-stat propulsion power converter. Th generator, a conventional two pol 60 Hz machine, produces a 416

VAC, 3-phase output. Power is dis tributed in this form via conver tional, medium-voltage cable an switchgear to the propulsion cor verter.

The converter consists of a diod rectifier front end and multipl

PWM inverter sections. The cor verter expands existing IGBT (Isc lated Gate Bipolar Transistor) based PWM technology to the me dium-voltage range. PWM techno] ogy has long been a desirable tech nology for vessel propulsion, but i has been unavailable in the require' power range until now.

Ship service DC power is pre duced by a conventional transforme and rectifier, distributed via D( cable and then converted to 60 o 400 Hz AC at the load site using sof switching type Ship Service Inverte

Modules.

The 15-phase propulsion motor i based on a commercial industria design. Each unit is installed as ; self-contained module. The entiri system is driven by Rolls Royce

Westinghouse gas turbines.

With a reduced defense budget t< consider, affordability and low-risl technology were prime consider ations for the project. That meani (Continued on page 38
