Pratt & Whitney F135 program completes post test Critical Design Review
April 7, 2005 (by

The Pratt & Whitney F135 System Development and Demonstration (SDD) program has successfully completed the post test Critical Design Review (CDR) by the Joint Strike Fighter (JSF) Joint Program Office (JPO).
The JPO review found that the F135 propulsion system has met all review objectives and is on track to deliver the first flight test engine later this year.
The Post Test CDR, conducted by government and industry experts appointed by the JSF JPO, is an independent review of the design of the production configuration F135 propulsion system. This review follows a pre-test CDR completed in May 2003 which cleared the way for nearly two years of SDD testing.
"Post Test CDR is a planned pause in the development process to assess the test data and ensure that we are on the right track," said Rob Burnes, director of propulsion for the JSF JPO. "This successful review shows that we are steering in the right direction."
"Completing the Post Test CDR is another in a series of milestones for the F135 program showing the maturity of this engine design," said Bill Gostic, vice president, F135 engine programs for Pratt & Whitney. "The design reflects experience from more than 2,500 SDD test hours on top of 3,500 pre-SDD hours over the course of the development program so far."
To date, the Pratt & Whitney led F135 propulsion team has delivered three Conventional Take-Off and Landing (CTOL)/Carrier Variant (CV) configuration and four Short Take-Off and Vertical Landing (STOVL) configuration F135 engines to test for a total of seven engines delivered on or ahead of schedule. In December, the team will deliver the first flight test engine in preparation for Initial Flight Release in January 2006 and first flight in August 2006. Production deliveries of the F135 are scheduled to begin in early 2009.
The F135 is an evolution of the highly successful F119 engine for the F/A-22 Raptor. Together the F135 and F119 will have logged more than one million flight hours in support of the F-35’s introduction to operational service in 2012.
The F135 propulsion system team consists of Pratt & Whitney, the prime contractor with responsibility for the main engine and system integration; Rolls-Royce, supplying lift components for the STOVL F-35B; and Hamilton Sundstrand, provider of the F135’s control system, external accessories and gearbox.
Pratt & Whitney military engine models include the F135 for the F-35 Joint Strike Fighter; the F119 powering the F/A-22 Raptor; the F117 for the C-17 Globemaster III; the F100 for F-15 and F-16 fighters; the J52 for the EA-6B Prowler; the TF33 powering AWACS, Joint STARS, B-52, C-141 and KC-135 aircraft; the PT6 for T-6A and UH-1N aircraft; and JT15 for the T-1A trainer and Pegasus UCAV.
Pratt & Whitney, a United Technologies company, is a world leader in the design, manufacture and service of aircraft engines, space propulsion systems and industrial gas turbines.
