Description: The GE Aviation Czech H80 is a 800-shp class turboprop engine derived from the design of the Walter Engines M601 engine series. It is intended to power utility, agriculture and business and general aviation aircraft. Compared to its predecessors the H80 is a more powerful, fuel-efficient, durable turboprop engine with significantly enhanced hot-day takeoff performance and high-altitude cruise speeds than current M601 engines. The H80 engine will also feature an extended service life of 3,600 flight-hours and 6,600 cycles between overhauls. EASA and FAA engine certification is planned for 2011.
GE's 3D aerodynamic design techniques and advanced materials have been integrated into the H80 engine's compressor, along with flow-path and material improvements to the turbine nozzle guide vanes. The H80's two-stage axial compressor also includes an innovative turbine blisk design.
