General Electric F118

The General Electric F118 is a non-afterburning turbofan engine produced by GE Aviation and derived from the F110 afterburning turbofan. It was specially developed as a non-afterburning derivative of the F110 for the B-2 Spirit stealth bomber. A single stage high pressure turbine drives a nine stage high pressure compressor, while a two stage low pressure turbine drives the three stage fan, and the combustor is annular. Thrust is in the 19,000 pounds-force class. In 1998 the United States Air Force Lockheed U-2S fleet was fitted with a modified version of the F118 with slightly lower thrust of 17,000 pounds-force. The F118-GE-100 is the variant for the B-2 and the F118-GE-101 is the variant for the U-2S.
