The CFM56-5A series is the initial CFM56-5 series, designed to power the short-to-medium range Airbus A320 family. Derived from the CFM56-2 and CFM56-3 families, the -5A series produces thrusts between 22,000 and 26,500 lbf (98 kN and 118 kN).
The CFM56 made its first commercial flight in April 1982 on a DC-8 Super 70 for Delta Airlines, on a route between Atlanta and Savannah, Georgia. In February 1987, Snecma achieved its initial goal of becoming a benchmark engine manufacturer for the new European twinjet, with the maiden flight of the CFM56-5-powered A320.
As an example the CFM International CFM56-5A engine active clearance control uses HPC air for the HPTACC and fan bypass air for the LPTACC.Clearance control is managed by the engine FADEC which consists of an electronic control unit (ECU), an hydromechanical unit (HMU) and HP and LP ACC valves.
As a result, many of the original customers switched their orders to the rival CFM56-5. To address the problem, Pratt & Whitney re-certified an updated design utilizing a six-stage high compressor designed by MTU Aero Engines in order to achieve promised performance. The German company manufactured the high-pressure compressor and the low ...
In terms of volume, the most impactful commercial aero engine produced by Safran Aircraft Engines is the CFM International CFM56 turbofan powerplant. This engine is both developed and manufactured via a 50-50 joint venture company, CFM International, which Safran jointly owns with the American industrial conglomerate General Electric (GE).
I don't think you need the Work Split subheading - it's too small a subsection and should just be another paragraph under CFM International. That's a fine suggestion, done. - SidewinderX ( talk ) 12:53, 28 December 2009 (UTC) [ reply ]

At the May 2017 EBACE, Aerion announced the selection of GE Aviation to power the Aerion AS2 supersonic business jet. [1] GE then launched the Affinity program. [2] The final engine configuration was a core with billions of operational hours – suggesting the CFM56 – and a new low-pressure section optimized for supersonic speed. [3]
