FARNBOROUGH, England, July 14 /PRNewswire/ -- FARNBOROUGH AIR SHOW --
The Pratt & Whitney F135 engine exceeded 10,000 system development and
demonstration (SDD) ground test hours this week. This achievement, in
addition to the 3,600 test hours accumulated during the F-35 concept
demonstration program, puts engine test program hours at more than 13,600.
Pratt & Whitney is a United Technologies Corp. (NYSE: UTX) company.
"This milestone, combined with the ongoing successful F-35 Lightning II
flight test programs for both the CTOL and STOVL variants, demonstrates the
dependability of Pratt & Whitney's F135 propulsion system," said Bill
Gostic, vice president, Pratt & Whitney F135 engine programs.
Achieving 10,000 test hours is one of a series of milestones for the
F135's SDD ground test program. Pratt & Whitney's F135 conventional
take-off and landing (CTOL) engine continues to power the F-35 Lightning II
flight test program with 43 flight tests and more than 52 flight test hours
to date. Pratt & Whitney's F135 short take-off and landing (STOVL)
propulsion system powered the first flight of the F-35B on June 11, and has
accomplished a total of three flight tests and 2.4 flight hours to date.
Rated at more than 40,000 pounds of thrust, the F135 is the most
powerful fighter engine ever built. The technologically advanced F135 is an
evolution of the highly successful F119 engine for the F-22 Raptor. By the
time the F- 35 enters operation in 2013, the F119 engines will have logged
more than 600,000 flight hours. In addition, the F135 will have logged
16,000 flight hours and more than 17,000 ground test hours. The ground and
flight test experience demonstrate the maturity and the associated
reliability of the F135 engine for armed forces around the world.
The F135 STOVL propulsion system team consists of Pratt & Whitney, the
prime contractor with responsibility for the main engine and system
integration; Rolls-Royce of the United Kingdom, which provides lift
components for the STOVL F-35B; and UTC's Hamilton Sundstrand unit,
provider of the engine control system and gearbox.
Pratt & Whitney is a world leader in the design, manufacture and
service of aircraft engines, space propulsion systems and industrial gas
turbines. United Technologies, based in Hartford, Conn., is a diversified
company providing high technology products and services to the global
aerospace and building industries.
