The CFM Work Split and Division of Labor

The work split for the CFM56 engine takes advantage of the technological expertise and achievements of both Snecma and GE.

Snecma is responsible for the low-pressure turbine in the rear of the engine, which drives the CFM56 fan in the front, also engineered by Snecma.

GE builds the CFM56 core, which is based on GE’s F101 engine (developed for the B-1 bomber). The engine’s core is the heart of any engine and is made up of three components: high-pressure compressor, combustor and high-pressure turbine.
