Engine Overview
The WALTER M601 series engines have been designed for commuter, agricultural, and trainer aircraft. The WALTER M601 engine is a free power turbine turboprop engine.
The WALTER M601 engine features two independent parts: the gas generator and power section. Air enters the engine in the rear part, flows forward through the compressor, combustion chamber, and turbines and exits through exhaust nozzles near the front of the engine.
The new M601H-80 derivative engine will incorporate GE's 3D-aero design and advanced materials into the engine's hot-section compressor and turbine as well as a new nozzle guide vane material in the gas generator and power turbine, new materials in the combustor liner and GE's blisk design in the axial compressor. These advanced technologies and designs will improve fuel efficiency by 7 percent compared to the existing M601F engine and offer increased temperature margin to improve hot day takeoff and high altitude cruise speeds. The M601H-80 engine will have an extended service life of 3,600 hours and 6,600 cycles between overhauls. The new derivative engine will offer power up to 800 shaft horsepower (shp). The new hot section will also be available as an upgrade to existing M601F engines.
