General Electric F101 Turbofan

The General Electric F101 was an aircraft turbofan jet engine designed and manufactured by General Electric to power the US Air Force B-1 bomber. The F101 was the first turbofan engine with an afterburner (augmentor) produced by General Electric. It was fitted with a one-stage low pressure compressor, a nine-stage high pressure compressor, a one-stage high pressure turbine, and a two-stage low pressure turbine. With an overall pressure ratio of 26.8:1, the turbofan F101 could produce a thurst of 31,000 lb (138kN) using afterburner. The F101 was later developed into the General Electric F110 and the CFM International CFM56.
