Engine Targeted At The GA And Biz Av Markets
The first H80 turboprop engine began its certification testing
on March 8 in a test cell at the GE Aviation Czech facility in
Prague in the Czech Republic.
"The first H80 engine to test met or exceeded all power ratings
in multiple runs," said Paul Theofan, president and managing
executive of GE Aviation Czech s.r.o., a wholly owned subsidiary of
GE Aviation. "Certification testing will continue this spring with
endurance testing starting next month and EASA type certification
anticipated this summer."
The H80 turboprop engine will produce up to 800 shaft horsepower
(shp) and power business and general aviation, utility and
agriculture aircraft. A total of five development engines will take
part in certification testing. Component, aeromechanical and
performance testing of the H80 engine have been underway for
several months. A hot section demo engine has accumulated more than
4,500 cycles of flawless performance.
By combining the elegant, robust design of the M601 engine with
GE's 3-D aerodynamic design techniques and advanced materials, the
H80 engine is a more powerful, fuel-efficient, durable turboprop
engine with no calendar limit and no hot section inspection. The
H80 engine will also feature an extended service life of 3,600
flight-hours and 6,600 cycles between overhauls, significantly
enhanced hot-day takeoff performance and high-altitude cruise
speeds. The H80 will provide the option of a single or dual acting
governor, allowing customers to select their propeller.
The H80 engine will enter service on the Thrush 510 this
summer. The engine will be the first of the new H80 engine
series family.
