Design and development
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. It was certified by the American Federal Aviation Authority on 17 December 1993.
