What Do a 757 and a C-17 Have in Common?
Pratt
& Whitney let us know that it has received a contract from the
U.S. Air Force valued at more than $1.4 billion to produce
F117-PW-100 engines that power the Boeing C-17 Globemaster III
strategic airlifter. The contract covers 240 engines, along with
associated spares and support services, to be delivered in
2004-2007.
"Pratt & Whitney is pleased that the U.S. Air Force
continues to demonstrate its confidence in the F117 engine and the
C-17 aircraft," said Steve Peery, director of Mobility programs,
P&W. "Both the aircraft and engines are performing superbly for
our Air Force customer. The C-17 is absolutely critical to our
forces in the war in Iraq and also the war on terror, and we are
very proud to be a part of this exceptional air system."
Four
F117-PW-100 engines power each C-17. (The F117 is a military
version of P&W's commercial PW2000 engine (shown), which has
been in service for nearly 20 years on the Boeing 757. The PW2000
has accumulated more than 25 million flight hours, is the most
fuel-efficient engine in its thrust class, and has an outstanding
record of performance and reliability.)
Let's back up...
One of the few differences between the commercial PW2000 and the
F117 is that the F117 has a unique thrust reverser system that can
be deployed in flight for tactical descents. It also enables the
aircraft to back up a two-degree incline and make tight turns on
the ground, providing more landing and unloading areas and faster
aircraft throughput. The F117 engines have logged more than one
million flight hours since their entry into service in September
1991. To date, P&W has delivered more than 520 F117 engines to
the U.S. Air Force.
The U.S. Air Force has ordered 180 C-17s, including 60 aircraft
placed on order in June 2002.
