This paper describes the design and test work of a development program of a 800-kW industrial gas turbine utilizing a jet engine gas generator. Design and subsequent manufacture of the power turbine assembly was predicated upon the use of aircraft engine components and technology. The gas turbine was initially intended as standby electric power source. It is planned to utilize the unit in continuous duty service. Solution of aerodynamic and mechanical design problems, and adaptation of control system are outlined. The results of prototype tests are also reported. Performance data correlated well with expected values. Several units have been installed up to date for standby utility service in industrial complexes, airport terminals and on ships. Operational experience with these engines is reviewed.
