GE Preps 1st Production H80 Engine For Thrush
 

According to both Thrush Aircraft and GE Aviation, next week will be an important one in the progress of the latter’s H80 turboprop engine. That’s when GE will deliver the first fully production compliant model for installation on the Thrush 510G agplane.

When it receives its FAA certification, expected before year end, the 510G will become the first new-build aircraft to be powered by the engine – a reworked power plant aimed directly at the market dominated for decades by the PT6, produced by GE Aviation’s arch rival, Pratt & Whitney.

Jody Bays, Thrush Aircraft’s vice president of Product Support and Development, says that when compared to the 750 shp PT6-powered 510P, the 800 shp GE version is 250 lb lighter, 10 mph faster, has better hot and high performance, and gets off the ground and climbs out faster.

Furthermore, since the GE’s “slinger” fuel feed design eschews fuel nozzles and requires no hot section inspection, “there’s essentially no real maintenance performed on the GE between TBOs,” and those come every 3600 hours.

Thrush is pricing both versions of the 510 at $852,635. The Albany, Ga.-based company plans to increase production of all its models from 36 aircraft this year to 48 in 2012. It hopes to deliver four Thrush 510Gs this year.

The H80 is derived from the M601, manufactured by Walter Engines, a Prague-based company GE acquired in 2008. Since then GE has invested considerably in its Czech facilities and reworked the engine with GE-developed three-dimensional aerodynamics and more advanced materials.

The GE engine has also been selected to power the Czech-built Let 410, whose first flight should occur in September, and a new Russian utility twin to be built by Rysachok. GE says other agplane makers have expressed interest in the engine, and that an amended STC for converting King Air 90s is in process.
