General Electric H80

The General Electric H80 is the initial engine of the H-Series, a family of turboprop aircraft engines produced by GE Aviation Czech. The H80 is an updated derivative of the Walter M601 that was launched in 2009, and the H75 and H85 are later derivatives. GE added a new compressor, blisks, blades and new stators to raise power by 3 percent and efficiency by 10 percent, so the engine reaches 597 kilowatts of shaft power against 580 kilowatts for the M601-F, with better hot and high performance. It has a two-shaft reverse flow layout with a two-stage axial and single-stage centrifugal compressor, an annular combustor and a two-stage planetary gearbox. EASA certificated it on 13 December 2011 and the FAA followed on 13 March 2012.
