Design

The CFE738 is comprised 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 240lb/s. The take-off thrust is 5600lbf, flat-rated to ISA+15C.

Derivatives

In the late 1980s, GE proposed a turboprop, the "T407" or "GLC38", for the Lockheed P-7, with a maximum takeoff power of 4,475 kW (6,000 SHP). The CFE738 is based on this engine.^[1]
The derivative GE38-1B (7,500 shp) is slated to power the new Sikorsky CH-53K three-engined helicopter for the USMC. ^[2]
