Power For The Thrush 510 Aerial Applicator
Thrush Aircraft, Inc., has selected GE Aviation's new H80
turboprop engine to power an improved version of its 510-gallon,
10,500-pounds gross weight Thrush aerial applicator (crop
duster). This is the first application for the H80 engine and
the first North American new engine installation for the Walter
M601 engine family.
The new H80-powered Thrush 510 is expected to gain certification
from the U.S. Federal Aviation Administration (FAA) next summer,
with initial customer deliveries to follow soon after.
"We selected the H80 engines based on GE's strong reputation for
engine performance and reliability, which are critical for our
customers," said Jody Bays, vice president, Flight Test and Product
Support for Thrush Aircraft. "The additional horsepower and
increased temperature margin of the H80 engine will enable Thrush
510 operators to carry larger loads in hot weather."
"This selection by Thrush marks the first application for GE
Aviation's new H80 engine, which will begin certification testing
later this year," said Brad Mottier, vice president and general
manager of GE Aviation's Business and General Aviation
organization. "We look forward to working with Thrush and its
customers and providing them with a powerful, fuel-efficient and
durable turboprop engine to meet their needs."
The H80 combines the robust turboprop design of Walter Aircraft
Engines' highly successful M601 series engines with GE Aviation's
modern 3D aerodynamic design techniques and advanced materials.
These technologies deliver more shaft-horsepower (shp), improved
engine fuel efficiency and increased temperature margin,
significantly enhancing hot-day takeoff performance and
high-altitude cruise speeds. The H80 engine also features an
extended service life of 3,600 hours and 6,600 cycles between
overhauls.
To date, the H80 engine has accumulated more than 3,000 cycles
during successful hot section demonstration tests. Additional
engine demonstration tests are scheduled for this summer and fall.
Engine certification testing is set to begin later this year, with
certification expected in early 2010.
An experimental Thrush 510 will be on static display at GE
Aviation's booth at this year's EAA AirVenture Oshkosh. The
aircraft on display will feature an M601E-11 engine that will be
replaced with an H80 engine for flight-testing and FAA
certification of the aircraft. Both engines share a common
installation and external dimensions. The aircraft has advanced
spray nozzles, high-intensity-discharge LED anti-collision lights
and a glass panel instrument display-all first-time features on a
Thrush aircraft.
With a hopper capacity of 510 gallons, a gross weight of 10,500
pounds, and the 800-shp H80 engine up front, the improved Thrush
510 is designed for superior performance for agricultural
operations. The Thrush features a 29,000-hour wing spar life with
no mandatory inspections of the wing spars. Additional
features include a tubular steel fuselage and cockpit roll cage,
removable fuselage skins, and chromate-treated aluminum surfaces
for corrosion prevention; all designed to maximize pilot safety,
reduce maintenance times and enhance aircraft productivity.
