CFM56-9 Brings Advanced Technology, High Reliability To 100-Passenger Aircraft Market

September 2, 1996

CFM International's proposed powerplant for the 100-passenger class aircraft market, the CFM56-9, combines proven, state-of-the-art technology with inherent CFM56 reliability. The end result is a low-cost derivative engine that is targeted to have 5 percent better specific fuel consumption (SFC) and 20 percent lower direct maintenance costs than the industry-leading CFM56-3* at the same thrust level.

CFM International (CFMI) is a 50/50 joint company of Snecma (Safran Group) of France and General Electric of the United States.

The CFM56-9 is sized to meet the thrust requirements of potential applications such as China's AE-100 and IPTN's N2130. CFMI has completed more than 70 percent of the engine design work and is prepared to certify the -9 within three years of aircraft launch to meet aircraft certification requirements.

The engine, rated from 18,500 to 23,000 pounds (82 to 102 kN) thrust, will incorporate a 56-inch, solid titanium, wide chord fan that will provide improved engine performance, durability, and repairability at a lower cost.

The engine's performance advantage is due, in part, to the 3-D aero technology used in the high and low pressure turbines and the high pressure compressor for increased efficiency. This technology is currently being proven in service on the CFM56-5B/P and will enter service on the CFM56-7 in 1997. The CFM56-9 shares a common core with these engines. This commonality will provide significant operating cost benefits to airlines already operating CFM56-powered fleets.

Another significant CFM56-9 advantage is the single stage high pressure turbine. This design feature, which has proven performance and reliability advantages, also translates to an engine with lower cost, lower weight, and less complexity.

The engine will be equipped with a single annular, low emissions combustor that will easily meet all anticipated regulations. CFMI is also incorporating its advanced FADEC (Full Authority Digital Electronic Control) system, which is fully integrated for ease of maintenance and has multi-functional capability.

CFMI estimates the potential sales for aircraft of this size to be about 1,200 aircraft over the next 20 years.
