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, and differ only in details.
CFM International is a Franco-American aircraft engine manufacturer. The company is a joint venture between GE Aerospace and Safran Aircraft Engines (formerly known as Snecma) and is headquartered in Cincinnati, Ohio. It was founded in 1974 to build and support the CFM56 series of turbofan engines.
The CFM International LEAP ("Leading Edge Aviation Propulsion") is a high-bypass turbofan engine produced by CFM International, a 50–50 joint venture between American GE Aerospace and French Safran Aircraft Engines. It is the successor of the CFM56 and competes with the Pratt & Whitney PW1000G to power narrow-body aircraft.
GE Aviation, part of the General Electric conglomerate, currently has the largest share of the turbofan engine market. Some of their engine models include the CF6 (available on the Boeing 767, Boeing 747, Airbus A330 and more), GE90 (only the Boeing 777) and GEnx (developed for the Boeing 747-8 & Boeing 787 Dreamliner and proposed for the Airbus A350) engines.
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).
CFM International CFM56 The PowerJet SaM146 is a turbofan engine produced by the PowerJet joint venture between Snecma ( Safran ) of France and NPO Saturn of Russia. [ 2 ] Developing 68–80 kN (15,000–18,000 lb f ) of thrust, the SaM146 is used on the Sukhoi Superjet 100 .
The DC-8-40 was essentially the -30 but with 17,500 lb (78.4 kN) Rolls-Royce Conway 509 turbofan engines for better efficiency, less noise and less smoke. The Conway was an improvement over the turbojets that preceded it, but the Series 40 sold poorly because of the traditional reluctance of U.S. airlines to buy a foreign product and because ...
The engine final assembly line is located at MTU Aero Engines at their location in Hanover, Germany. LAN Airlines confirmed an order for 15 Airbus A318 aircraft, for a total of 34 engines (30 installed and 4 spares) powered by PW-6000 engines on 15 August 2005. In addition, LAN signed with Pratt and Whitney to power up to 25 option aircraft.
