Engine To Power The PiperJet Altaire, Nextant 400XT
The FAA has issued a Part 33 type certificate to Williams
International for its new FJ44-3AP engine, an improved version of
its FJ44-3A. State-of-the-art aerodynamics and structural
enhancements have led what the company says is a new benchmark in
thrust-to-weight ratio and fuel economy. Thrust was increased 8% to
more than 3000 pounds, while weight was reduced 3%. The
market-leading performance of the FJ44-3AP engine has already won
it three new applications - the Nextant 400XT, the Hawker 200, and
the PiperJet Altaire.
"I want to thank the FAA for their strong support in achieving
this milestone," said Gregg Williams, Chairman, President & CEO
of Williams International. "I am also very proud of our team for
developing significant improvements to what was already a very good
engine. The outstanding performance of the FJ44-3AP engine will
lead to many new and improved airplanes."
"The FJ44-3AP is also the first to receive FAA certification of
a new proprietary feature we developed," Williams added, "that
converts into thrust the energy typically wasted pre-cooling engine
bleed air for use in aircraft anti-icing systems. This feature,
which enables much better performance in icing conditions, will be
offered on Williams' other commercial engines."
The FJ44-3AP joins a comprehensive
product line of FJ33 and FJ44 engines that covers the thrust
spectrum from 1000 to 3600 pounds thrust. All have rugged and
efficient wide-sweep fans, health-monitoring FADEC controls, and
low-emissions combustor technology.
While Williams engines are already recognized for their
ruggedness and reliability, the FJ44-3AP engine incorporates
durability improvements gleaned from over 6 million hours of
operation of the 4000 FJ44 engines in service. Williams
International's world class product support network continues to
rank first in annual surveys of owners and operators, due in part
to Williams' Total Assurance Program (TAP) that provides more value
at lower cost than any competing engine maintenance program.
