Design of high-reliability gas turbine controls and accessories: Final report

Schematic diagrams and reliability analyses are presented for the ''controls and accessories'' systems for General Electric's Model 7F advanced gas turbine. This project was to apply rigorous reliability engineering methods to the design of a new gas turbine. The focus of the project was the controls and accessories systems, because in the past most of the failures occurred with these systems. A database of the reliability of each of the many components that make up the gas turbine was established from the maintenance histories of existing (similar) models. The project was successful in that it significantly influenced the design of a new electric power generating system. The report provides an in-depth analysis of each of the eighteen systems that make up the ''controls and accessories'' systems. 4 refs., 76 figs., 61 tabs.
