CFM International CFM56-7B
The CFM International CFM56-7B is the turbofan series developed as the exclusive powerplant for Boeing's Next-Generation 737. A large fan and gas-turbine core provide thrust for the twin-engine airliner, while successive production improvements addressed fuel consumption, durability and maintenance. The -7B series contains multiple certified models and ratings; an individual dash-number engine should be identified before applying model-specific performance or operating limits.
