Developed from General Electric GE27

The CFE738 is a small turbofan engine aimed at the business/commuter jet market manufactured by the CFE Company, and is used on the Dassault Falcon 2000.

Design and development[edit]

The success of the GE27/GLC38 gas generator development of the 1980s led to the formation of the CFE Company by GE and the Garrett Engine Division of Allied Signal(now Honeywell) in 1987.

The CFE738 consists of a single stage fan, driven by a 3-stage low-pressure (LP) turbine, supercharging a 5-stage high-pressure (HP) axial/centrifugal compressor driven by a 2-stage HP turbine. The engine has an overall pressure ratio of 35:1, which is extremely high for an engine with a centrifugal compressor. Other cycle parameters are a bypass ratio 5.3 and airflow of 240 lb/s (108.9 kg/s). The take-off thrust is 5,600 lbf (24.9 kN), flat-rated to ISA+15C.

The engine was first run in 1990 and first flown on a Boeing 727 testbed on 31 August 1992.[1] It was certified by the American Federal Aviation Authority on 17 December 1993.
