The General Electric CF6 is a family of high-bypass turbofan engines produced by GE Aviation. Based on the TF39, the first high-power high-bypass jet engine, the CF6 powers a wide variety of civilian airliners. The basic engine core also powers the LM2500, LM5000, and LM6000 marine and power generation turboshafts.
GE intends to replace the CF6 family with the GEnx.
After developing the TF39 for the C-5 Galaxy in the late 1960s, GE offered a more powerful variant for civilian use, the CF6, and quickly found interest in two designs being offered for a recent Eastern Airlines contract, the Lockheed L-1011 and McDonnell Douglas DC-10. The L-1011 eventually selected the Rolls-Royce RB211, but the DC-10 stuck with the CF6, and entered service in 1971. It was also selected for versions of the Boeing 747. Since then, the CF6 has powered versions of the Airbus A300, 310 and 330, Boeing 767, and McDonnell Douglas MD-11. The high bypass of the CF6 represented a historic breakthrough in fuel efficiency.
In 2000, the NTSB warned that the high-pressure compressor could crack. In 2010, it warned that the low-pressure turbine rotor disks could fail.
The CF6-6 was a development of the military TF39. It was first used on the McDonnell Douglas DC-10-10.
