CFM56-2 series

This is the earliest of the series with a thrust range of between 22,000 to 24,000 lbf (98 kN to 108 kN). It first appeared in the re-engined Douglas DC-8 Super 70 in 1982. Its success led to it re-engining military variants of Boeing 707. F108 is the engine's U.S. military designation. Today, the U.S. Air Force is CFM's largest customer, with more than 450 re-engined aircraft in service, or 1,800 CFM56-2 engines.

It is the most numerous turbofan variant in aviation history with 3,975 engines produced for the 737-300/-400/-500. It is very reliable and has a high resale value.


CFM56-5 series

The CFM56-5 series is designed for the Airbus aircraft. It has a very wide thrust rating of between 22,000 to 34,000 lbf (98 kN to 151 kN). It differs from its Boeing fitted cousins by features such as FADEC, advanced internal design giving improved performance over the CFM56-3 whilst maintaining the CFM56-3 reliability. It has 3 distinct sub-variants, the CFM56-5A, CFM56-5B and CFM56-5C. Both the CFM56-5A and CFM56-5B are ETOPS rated. The CFM56-5C is not due to its application in the 4-engined Airbus A340. The Airbus designator for any aircraft equipped with CFM engines is "1"; eg. A320-211 or A340-312. Airbus S.A.S. better known as simply Airbus, based in Toulouse, France, is the worlds largest commercial aircraft manufacturer. ... FADEC is the acronym for Full Authority Digital Engine Control. ... ETOPS (Extended Twin-engine OPerationS) is an acronym for an International Civil Aviation Organization (ICAO) rule permitting newer twin-engined commercial air transports to fly routes that, at some points, are further than a distance of 60 minutes flying time from an emergency or diversion airport. ...

CFM56-5A series

CFM56-5A series is designed to power the short-to-medium range Airbus A320, with thrusts between 22,000 to 26,500 lbf (98 kN to 118 kN). This is the initial CFM56-5 series. Its design is derived from the CFM56-2 and CFM56-3 families. The Airbus A320 is a short to medium range commercial passenger aircraft manufactured by Airbus. ...


CFM56-5B series

An improvement of the CFM56-5A series, it was originally designed to power the A321. Today, it powers every model in the A320 family (A318/A319/A320/A321), and has superseded the CFM56-5A series. Among the change over the CFM56-5A is the double annular combustor technology which reduces oxides of nitrogen emission by as much as 45 percent. It is also the most numerous engine supplied to Airbus. The thrust range is between 22,000 to 33,000 lbf (98 kN to 147 kN).

For the A340, CFM International supplies the CFM56-5C series as a total propulsion system: engine, nacelle, and exhaust systems as opposed to just bare engines of the other variants.


It features exhaust design featuring mixer and an integrated nozzle for good efficiency (this design is also found in IAE V2500 series and on some Rolls-Royce RB211 series) and it also features the unique 'petal' thrust reversers rather than the conventional cascade design. This is due to the A340 requirements of maximum range and efficiency. Categories: Stub | Turbofan engines ... Rolls-Royce RB211 engine The Rolls Royce RB.211 family is a family of high-bypass turbofan aircraft engines made by Rolls-Royce capable of generating 37,400 to 60,600 pound (166 to 270 kN) thrust. ...


CFM56-7 series

The CFM56-7 powers the Next-Generation 737(Boeing 737-600/-700/-800/-900). The CFM56-7 is rated with takeoff thrust from 18,500 to 27,300 lbf (82 kN to 121 kN).


It has higher thrusts, improved efficiency, and lower maintenance costs than its predecessor, the CFM56-3 series. It incorporates many features from the CFM56-5 series such as FADEC, double annular combustor and improved internal design. FADEC is the acronym for Full Authority Digital Engine Control. ...


The CFM56-7-powered 737 is granted 180-minute Extended-Range, Twin-Engine Operations (ETOPS) approval by the U.S. Federal Aviation Administration. It also powers the military versions of the Next-Generation 737, the C-40 Clipper, Multimission Maritime Aircraft, and Project Wedgetail..
