How many CFM56 5b engines are in service?
It has more than 550 operators and more than 2,400 CFM56-powered jet aircraft are in the air at any moment. It is known for its dependability: its average time on wing is 30,000 hours before a first shop visit, with the current fleet record at 50,000 hours.
What does CFM stand for in jet engines?
CFM is not an acronym, so it doesn’t stand for anything. The company (CFM), and product line (CFM56), got their names by a combination of the two parent companies’ commercial engine designations: GE ‘s CF6 and Snecma’s M56.

Where is jet fuel made?
crude oil
Jet fuels are primarily derived from crude oil, the common name for liquid petroleum. These jet fuels can be referred to as petroleum-derived jet fuels. Jet fuels can also originate from an organic material found in shale, called kerogen or petroleum solids: that can be converted by heat to shale oil.
What kind of engine is a CFM56?
The CFM International CFM56 (U.S. military designation F108) series is a family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of 18,000 to 34,000 pounds-force (80 to 150 kilonewtons). CFMI is a 50–50 joint-owned company of SNECMA, France and GE Aviation (GE), USA.
How much thrust does a CFM56 turbofan have?
The CFM56 is a high-bypass turbofan engine (most of the air accelerated by the fan bypasses the core of the engine and is exhausted out of the fan case) with several variants having bypass ratios ranging from 5:1 to 6:1, generating 18,500 to 34,000 lbf (80 kN to 150 kN) of thrust. The variants share a common design, but the details differ.
Which is the most powerful of the CFM56 family?
With a thrust rating of between 31,200 and 34,000 lbf (139 kN and 151 kN), the CFM56-5C series is the most powerful of the CFM56 family. It powers Airbus’ long-range A340-200 and -300 airliners, and entered service in 1993. The major changes are a larger fan, a fifth low-pressure turbine stage,…
Is the CFM56 a replacement for the F108?
About the F108/CFM56: LEAP is the replacement engine for the CFM56. The changeover to production of LEAP engines is currently in progress. The CFM56 has contributed significantly to the design of the LEAP engine by driving reliability and maintenance cost design practices. CFM expects to produce more than 2,000 LEAP engines annually by 2020.
