SINGAPORE February 26, 2002 Airbus Industrie has confirmed that the CFM56-5B will be the first engine in service on the new A318. The engine is on schedule for certification in the second quarter of 2002 and will begin flight tests on the A318 later this year. The first CFM56-5-powered A318 will be delivered to Air France in the third quarter of 2003.
CFM56-5 engines are produced by CFM International, a 50/50 joint company between Snecma Moteurs (Safran Group) of France and General Electric of the United States.
As the only engine that can power every model of the A320 family with one bill of materials, the CFM56-5B provides airlines a distinct commonality advantage, in addition to the lowest cost of operation on this application. In addition to the Air France order (15 firm, 10 option), GE Capital Aviation Services also has 30 CFM56-5B-powered A318s on order.
Noise and emissions have become key factors in aircraft fleet planning and operations. The CFM56-5B is the only engine on the A320 family to offer advanced double annular combustor (DAC) technology. The CFM DAC reduces NOx (oxides of nitrogen) emissions by as much as 45 percent. The technology has been so well received in the marketplace that nearly 40 percent of all CFM56-5B-powered A320s in service or on order with European airlines are equipped with this technology.
All CFM-powered A320 family aircraft meet current FAR Stage III noise requirements with significant margin. These engines also meet the CAEP 5 recommendations, except for the CFM56-5B-powered A321. However, CFM and Airbus have defined an acoustic package to ensure this aircraft will operate well within proposed limits. CFM is conducting development testing on engine and nacelle treatments that will reduce the cumulative noise signature at least 10 EPNdB (effective perceived noise in decibels) below Stage III levels.
The new technology includes three-dimensional aerodynamic designed outlet guide vanes; a core chevron nozzle; and improved reverser and inlet linings on the nacelle. Flight tests on the A321 are scheduled for later this year, followed by certification and entry into service in early 2003.
The CFM56-5 continues to be the engine of choice for the Airbus A320 family, having been selected to power 55 percent of all A318/A319/A320/A321 aircraft ordered to date.
CFM International is a joint company of Snecma (Safran Group), France and General Electric Company, U.S.A.
