TheCFE CFE738 is a smallturbofan engine aimed at the business/commuter jet market manufactured by theCFE Company, and is used on theDassault Falcon 2000.
The success of theGE27/GLC38 gas generator development of the 1980s led to the formation of theCFE Company by GE and theGarrett Engine Division ofAllied Signal (now Honeywell) in 1987.
The CFE738 is a two-shaft design, consisting of a single stagebypass fan connected via one shaft to a 3-stage low-pressure (LP)turbine at the rear of the engine; with a six-stage combination low-pressure/high-pressure (LP/HP) axial/centrifugal compressor (five axial stages and one centrifugal stage) 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 anoverall pressure ratio of 35:1, which is extremely high for an engine with a centrifugal compressor. Other cycle parameters are abypass ratio of 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 toISA +15°C (30°C, 86°F).
Chosen to power the Falcon 2000 in 1990, the engine was also first run in May 1990,[1] and it was first flown on aBoeing 727 testbed on 31 August 1992.[2] The CFE738-1 made its inaugural flight on a Falcon 2000 prototype on March 4, 1993. It was certified by the United StatesFederal Aviation Administration (FAA) on December 17, 1993,[1] and it entered service in 1994.[3]
