M601: Undisputed Results for Unmatched Value

The GE M601 series engines have been designed for commuter, agricultural, and trainer aircraft. The GE M601 engine is a free power turbine turboprop engine.

The GE M601 engine features two independent parts: the gas generator and power section. Air enters the engine in the rear, flows forward through the compressor, combustion chamber, and turbines and exits through exhaust nozzles near the front of the engine.

The new GE H80 engine will incorporate GE's 3D-aero design and advanced materials into the engine's compressor and turbine as well as nozzle guide vanes and GE's blisk design in the axial compressor. These advanced technologies and designs will improve fuel efficiency and offer increased temperature margin to improve hot day takeoff and high altitude cruise speeds. The H80 engine will offer power up to 800 shaft horsepower (shp) and will have an extended service life of 3,600 hours and 6,600 cycles between overhauls.
