The Pratt & Whitney F117-PW-100 two-spool high-bypass turbofan engine is the military
version of the commercial PW2040 engine used on the Boeing 757. The F117 features a Full-Authority Digital Engine Control (FADEC) system,
which provides higher operational performance, lower fuel burn and advanced maintenance diagnostics.
The F117 was selected by the U.S. Air Force as the exclusive power plant for the C-17 Globemaster III military transport aircraft.
The Boeing
C–17 Globemaster III
is a four-engine widebody aircraft capable of airlifting outsized and oversized payloads over intercontinental ranges with or without in-flight refueling.
Its capabilities include rapid direct delivery of forces by air, land or airdrop into difficult tactical environments with runways as short as 3,000 feet.
On the C-17, each of the four F117 engines produces 40,440 pounds of thrust.
Unique to the C-17, the F117 engines are equipped with a directed-flow thrust reverser capable of being deployed in flight.
On the ground, the thrust reverser can back a fully loaded aircraft up a two-degree slope.
The F117 first entered service in 1993. To date, F117 engines have accumulated more than 12 million flight operating hours in support of military and humanitarian missions around the world.
With 12+ million hours of military service and 50 million hours in commercial use, the F117/PW2040 has proven itself as a highly dependable engine.
In January 2016, the 1,313th and final production engine was delivered to the U.S. Air Force.
The F117 was built at Pratt & Whitney's Engine Center in Middletown, Connecticut.
The F117 engine can remain on-wing for up to eight years between servicing visits.
Recently, the F117 exceeded 9,000 hours in mean time between removal.
This lowers MRO costs and provides outstanding mission readiness for C-17 operators.
The F117 powers nine C-17 fleets around the world, including the U.S. Air Force, the Royal Australian Air Force, the British Royal Air Force,
the Royal Canadian Air Force, the Qatar Emiri Air Force, the United Arab Emirates Air Force, the Indian Air Force, the NATO Airlift Management Programme (NSPA),
and the Kuwaiti Air Force.
