GE working on new engine for GA aircraft

Component testing of the H80 engine has been underway for several months, and GE has recently started aeromechanical and performance testing on test engines.

"The results from our component and engine demonstration tests of the H80 engine have been very positive, and we look forward to the start of certification testing on the H80 engine, which is the first new commercial turboprop engine for GE in more than a decade," says Brad Mottier, vice president and general manager of the Business and General Aviation organization at GE Aviation.

The H80 engine combines the elegant, robust design of the M601 engine with GE's 3-D aerodynamic design techniques and advanced materials to create a more powerful, fuel-efficient, durable turboprop engine with significantly enhancing hot-day takeoff performance and high-altitude cruise speeds. The H80 engine will also feature an extended service life of 3,600 flight-hours and 6,600 cycles between overhauls.

Engine certification of the H80 is expected in early 2010 with entry into service on the Thrush 510 to quickly follow.
