CFE CFE738


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

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 in 1987.
The CFE738 is a two-shaft design, consisting of a single stage bypass fan connected via one shaft to a 3-stage low-pressure turbine at the rear of the engine; with a six-stage combination low-pressure/high-pressure axial/centrifugal compressor driven by a two-stage HP turbine, between the fan and the LP turbine, on the other shaft. There is an axial combustion chamber between the compressor stages and the HP turbine. A mixer is built in to the jetpipe to mix cold bypass air with the hot exhaust gases. 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 of 5.3 and airflow of 240 lb/s. The take-off thrust is 5,600 lbf, flat-rated to ISA +15°C.
The engine was first run in 1990 and first flown on a Boeing 727 testbed on 31 August 1992. It was certified by the American Federal Aviation Authority on 17 December 1993.
