Pratt & Whitney Reveals F135 Status
At the Paris Airshow, Pratt & Whitney provided a status report of the F135 engine that will power the Lockheed Martin F-35 Joint Strike Fighter. The engine has logged 11,000 ground-test hours and more than 100 flight test hours in the conventional takeoff and landing (CTOL) mode. It also recently completed hover pit testing in preparation for the aircraft's operation in short takeoff and vertical lift (STOVL) mode. Evolving from F119 engine for the F-22, the F135 was designed to require 30 to 50 percent fewer maintenance technicians and reduce the time for fault detection and repair by 94 percent, while increasing the time between shop visits by 225 percent over legacy systems.
Engine Maker Also Partners with Turkish Firm
Pratt & Whitney and Kale Havacilik AS, Istanbul, Turkey, have signed a memorandum of understanding aimed at establishing a joint venture partnership to produce aircraft engine components. Kale will be majority partner with 51 percent share of the new company. The JV will specialize in manufacturing hardware for the Lockheed Martin F-35 Joint Strike Fighter. In the future, according to Pratt & Whitney, the Turkish partnership will expand to support complex metal fabrications and spare parts for the F100, F119 and F117 military engines, which power the F-16 and F-15, the F-22 and the C-17, respectively.
Chromalloy to Provide F108 Repairs
The U.S. Air Force has awarded a contract to Chromalloy to conduct module repairs on the KC135R tanker's F108 turbine engine. The follow-on contract, worth $15.8 million plus options, brings the total agreement to around $38 million over three years. Chromalloy will overhaul the rotor stator modules, including the turbine frame, during KC135R heavy maintenance.
