General Electric TF39

Common card · No. 441481

The General Electric TF39 was a high-bypass turbofan engine that was developed to power the Lockheed C-5 Galaxy. It was the first high-bypass jet engine to enter service, becoming operational on the Galaxy fleet in 1970. With further modifications, it became the civilian General Electric CF6, entering service in 1971 on the McDonnell Douglas DC-10, and seeing use in a wide variety of aircraft from Boeing and Airbus. The internal power section, with the front fan removed, formed the General Electric LM2500 marine turbine. The last TF39 was produced in March 2016, and the last operational use of the engine was the next year, after the Galaxy fleet was re-engined with the F138, a derivative of the CF6.
