New Engine Powers Hawker 900XP
Honeywell announced Wednesday at NBAA 2007 it has received
Federal Aviation Administration certification for its TFE731-50R
turbofan engine that Hawker Beechcraft Corporation selected to
power its new Hawker 900XP.
The engine is designed to deliver up to 5,000 pounds of take-off
thrust and includes integrated nacelle and thrust reverser systems.
In its Hawker 900XP configuration, the installed engine will
deliver 4,900 lbs of thrust.
Honeywell has shipped 27 shipsets to Hawker Beechcraft
Corporation for installation on the new Hawker 900XP aircraft.
“The engine is certified to 5,000 pounds of thrust and has
significantly improved temperature margin, which will give our
customers an engine with incredible durability,” said Ben
Driggs, Vice President of Marketing at Honeywell Aerospace.
“Coupled with reduced Thrust Specific Fuel Consumption at
cruise and improved climb thrust, the -50R will deliver the
performance and reliability our customers want.”
The TFE731-50R turbofan engine joins the TFE731-20/40/60
propulsion family of 1,700 fielded propulsion engines with more
than four million service hours. The TFE731-50R is a low risk
derivative of the current –60 production engine, utilizing a
common core and a scaled wide chord damperless fan. The engine will
operate at a cooler internal temperature than other TFE731 engines
and will give Hawker 900XP operators mature engine reliability at
entry into service.
“With a scaled wide chord damperless fan, the engine will
deliver seven percent range improvements for ISA-day takeoffs when
flat rated to the same thrust as the TFE731-5BR. The -50R will
yield up to a 24 percent range improvement for ‘Hot and
High’ takeoff, while delivering lower operating costs,”
Driggs said.
The TFE731-50R utilizes an N1 Digital Electronic Engine Control
with hydromechanical backup, single-crystal blade material in the
high-pressure and first stage low-pressure turbines as well as
improved vane and blade cooling effectiveness. Other engine
enhancements include durability improvements in the compressor that
extend engine life and reduce maintenance costs.
