In commercial service, the CF6-80C2 is featured on the Airbus A300-600, Boeing 767 (also uses the CF6-80A), Boeing 747-400/400ER, and McDonnell-Douglas MD-11 aircraft.
Who makes the CF6 engine?
GE
In the spring of 1968, both United Airlines and American Airlines selected the 40,000 pound thrust GE CF6-6 to power their Douglas DC-10 Series 10 aircraft. As a result, GE began its 45-year legacy in commercial aviation.
What does CF6 stand for?
CF6

How much is a CF6 engine?
GE CF6-80C2 Engine Order From Continental Valued at $160 Million | GE Aviation.
What engine is in the 747?
The 747 is a quadjet, initially powered by JT9D turbofan engines, then GE CF6 and Rolls-Royce RB211 engines for the original variants.
How many CF6 engines are in service?
The in-service fleet include 3,400 engines, more than all the GE90s and GEnx, generating over than 600 shop visits per year. GE will be delivering engines well into the 2020s and they will fly for 20 to 25 years, until 2045-50: more than 75 years since the first CF6.
What drives the fan in a turbofan engine?
Low-bypass turbofan The fan (and booster stages) are driven by the low-pressure turbine, whereas the high-pressure compressor is powered by the high-pressure turbine.
What planes use GE engines?
Boeing installs GE engines on its 747, 767, 777 and 787 families of aircraft. Boeing’s mainstay 737 family of aircraft uses engines made by CFM International, a joint venture between GE and Safran – the same Safran launched a joint venture with Boeing to produce auxiliary power units (APU).
Why was the 747 discontinued?
The end of the 747 has been a long time coming. Demand for the four-engine jet has decreased steadily in recent years as airlines have sought smaller, nimbler, more fuel-efficient twin-engine planes instead, such as the Airbus A330 and A350, and the Boeing 777 and 787.
Why 747 has a hump?
Hence the engineers went for a second deck that housed the cockpit in the Boeing 747-100. Because of aerodynamics, the cockpit level had to rise and slope back down to the main fuselage, giving us the iconic hump.
Are turbojets still used?
The turbojet is an airbreathing jet engine, typically used in aircraft. Turbojets have been replaced in slower aircraft by turboprops because they have better specific fuel consumption. At medium to high speeds, where the propeller is no longer efficient, turboprops have been replaced by turbofans.
Can turbofans go supersonic?
Turbofans can tolerate supersonic speeds because the intake creates constant flow conditions irrespective of flight speed. Efficiency for propellers and fan blades is highest at subsonic flow conditions.
