General Electric H75 / H80 / H85

 

The General Electric H80 is a turboprop aircraft engine produced by GE BGA Turboprops. The H80 is an updated derivative of the Walter M601. First run in 2009, FAA certification of the engine obtained at 13 March 2012. Russian type certificate received in October 2012 also approved by EASA, Brazilian Civil Aviation agency (ANAC) and the Argentine Administración Nacional de Aviación Civil.

The H80 will update the legacy M601 in several ways, including power and efficiency. The H80 will be a significant power upgrade over the M601, reaching 800 shaft horsepower (shp) rather than the 650 shp of the M601. Another important upgrade to the engine will be improving its hot day performance. That improvement is a major reason why the H80 was selected to power the Thrush Model 510 as a crop duster for Afghanistan.


Thrush Aircraft has exclusively teamed with General Electric to produce the Thrush 510G powered by the GE H80 turbine engine. The H80 provides increased temperature margins to enhance hot-day takeoff performance and high-altitude cruise speeds. GE chose Thrush to launch this new engine.

The GE H80 turboprop engine that powers the Thrush 510G was initially based upon the Walter M601 engine. The new H80 represents a complete rethink by GE Aviation that resulted in a free-turbine design that is lighter, more powerful, and more fuel efficient. In addition, the H80 has the ability to produce its full-rated 800 shp at high altitudes and field elevations, even on the hottest of days. Plus, the H80 requires no hot section inspection, and has a TBO of 3,600 hours.
