Description:
CFM International is a 50/50 joint venture between French Snecma Moteurs and American General Electric. The CFM56 family of engines, CFM International main product, is named after General Electric's CF6 and Snecma's M56 engines. More than 13,500 CFM56 engines have been delivered to more than 350 customers all over the world.
CFM56 engines have been designed to power short-, medium-, and long-range commercial and military aircraft since the first CFM56-1 entered service in 1974. These single-stage turbofans are currently available ranging from 18,500 to 34,000 pounds of thrust and four fan sizes.
The CFM56-7 is the latest member of successful CFM56 family of engines. It has a dual annular combustor for low emissions capability and reduced fuel burn through advanced thermodynamic cycle. Its thrust ranges between 18,500 and 27,300 pounds.
CFM56-7 engines provide next generation Boeing 737 aircraft higher levels of reliability, lower fuel consumption, higher thrust and lower maintenance costs than its predecessor the CFM56-3 engine. The first -7 model entered service in 1997 powering a Boeing 737-700.
More than 3,000 CFM56-7 engines have been ordered to power the next generation Boeing 737 (-600, -700, -800 and -900) and Boeing business jet as well as 737-based modern military aircraft such as the 737 AEW&C, C-40 Clipper and 737 MMA aircraft.
