The CFM International CFM56 (U.S. military designation F108) series is a Franco-American family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of 18,500 to 34,000 lbf (82 to 150 kN).

The CFM56-3 turbofan engine is a prominent high-bypass, dual rotor engine variant known for its efficiency and thrust capabilities, particularly in commercial aviation, such as on the Boeing 737 models.

The CFM56-3 is a high bypass, dual rotor, axial flow turbofan engine. Basic engine specification are provided in Fig 1 and 2. The integrated fan and booster (low pressure turbine-LPC) is driven by a 4 stage low pressure turbine (LPT). A single stage high pressure turbine (HPT) drives the 9 stage high pressure compressor (HPC)

The CFM56 engine set the industry standard for single-aisle commercial jet engines that holds today. Owing its success to its exceptional reliability and performance, CFM56 was built on over four decades of experience and technological excellence. With more than 33,000 engines delivered to date, it powers more than 600 operators worldwide.

cfm56-5a系列是cfm56-5系列的最初版本，为短程至中程的空中客车a320家族设计，衍生自cfm56-2和cfm56-3系列，推力介于22,000至26,500磅（98至118千牛）之间。 得益于在空气动力学上的改进，例如新的风扇、压气机和燃烧室，这一系列发动机相对之前型号能够减少10-11%的 ...

Its specifications & EGT margin performance are examined. The CFM56-3 is the second of five series of the CFM56 engine model, and was the first to sell several thousand units. Certified in 1984, the CFM56-3 ceased production in 1999, after some 4,500 units had been built.

The CFM56-3 was designed for Boeing 737-300/-400/-500 Classic aircraft. Derived from the CFM56-2, this super-reliable turbofan is still in service worldwide. The CFM56-3-powered Boeing 737 revenue service in 1984 and quickly became one of the best-selling engine/aircraft combinations ever.

With nearly 33,000 engines delivered to some 600 commercial and military operators around the globe, CFM International’s CFM56 product line powers the world’s most successful aircraft, including the Airbus A320ceo and neo families and the …

With more than 33,000 delivered to date, CFM56® engines mainly power single-aisle commercial jets from Airbus and Boeing. The CFM56®, developing 18,500 to 33,000 lb of thrust, set a standard in this market. It owes its impressive success to exceptional performance and reliability, the result of the two partners' technical excellence.

As the sole powerplant for the 737-300/-400/-500, the CFM56-3 will continue operating in large numbers for another 20 years on account of the aircraft’s popularity. The CFM56 family has a two-shaft design and provides a range of engines rated between 18,000lbs and 34,000lbs thrust across five series.
