Significant advances in all elements of gas turbine design technologies have occurred during the past decade. These developments have created a technical climate conducive to the creation of a totally new heavy-duty gas turbine, as opposed to the uprating of an existing design. This paper discusses the features and characteristics of a new heavy-duty gas turbine that takes advantage of the latest technological advances. Discussed are the basis for design parameter selection, the operating characteristics, the materials of construction, and the component design features. Also presented are the features and performance of the unique combustion system and the results of and plans for component and prototype testing. This paper represents a comprehensive treatment of this advanced gas turbine, which is in the initial manufacturing stage in preparation for extensive factory testing followed by shipment to a customer by mid-1988.
