CFM-56 - Family of Engines : Celerity Asset Management has a unique focus on the CFM56 family of engines which power a large volume of narrowbody or single-aisle aircraft. This family of high-bypass turbofan aircraft engines is made by CFM International (CFMI), a 50–50 joint-owned company of Safran Aircraft Engines of France and GE Aviation (GE) of the United States. 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. The CFM56 is a two-shaft (or two-spool) engine, meaning there are two rotating shafts, one high-pressure and one low-pressure. Each is powered by its own turbine section (the high-pressure and low-pressure turbines, respectively). The fan and booster (low-pressure compressor) evolved over the different iterations of the engine, as did the compressor, combustor and turbine sections. The CFM56 variants include the; CFM56-2 series, CFM56-3 series, CFM56-4 series, CFM56-5 series, CFM56-5A series, CFM56-5B series, CFM56-5C series and CFM56-7 series.
