Rappel du premier message :

Bonjour à tous,

Le F-35 est l'avenir de beaucoup de forces aériennes, il remplacera les F-16, A-10, Harrier et autres. Je propose que soient postées ici, si vous êtres d'accord, toutes les infos au sujet du F-35. Merci de m'avoir lu.

Article (en anglais) fort intéressant sur l'avion qui comprend un pdf avec les différents armements que pourra emporter le F-35, tant en soutes, que sous les ailes. Furtif, moins furtif...

Dans cet autre article, une image montre qu'il serait aussi possible de rajouter de l'armement en bout d'aile, info, intox?

F135 Engine Exceeds 12,000 Engine Test Hours as Pratt & Whitney Prepares to Deliver First Production Engines


Wednesday, Jul 29, 2009


EAST HARTFORD, Conn., July 28 /PRNewswire-FirstCall/ -- The Pratt & Whitney F135 engine has surpassed 12,000 engine test hours as part of the system development and demonstration (SDD) phase of the development program. This achievement, in addition to the 3,600 test hours accumulated during the F-35 concept demonstration program, puts F135 engine test hours at more than 15,600. Pratt & Whitney is a United Technologies Corp.

"Pratt & Whitney is proud of the F135's performance in the successful ground and flight test programs," said Warren Boley, vice president, Pratt & Whitney F135 engine programs. "This successful testing demonstrates the dependability and reliability of Pratt & Whitney's F135 propulsion system and the maturity that comes with the first production engines that we will deliver later this year."

The F135 engine program remains on track to support overall F-35 development and transition to production. Pratt & Whitney is scheduled to deliver the first seven production F135 engines later this year. The F135 conventional take-off and landing (CTOL) engine and short take-off and vertical landing (STOVL) propulsion system continue to power the F-35 Lightning II flight test programs with 113 flights and more than 134 flight test hours. Additionally,

Pratt & Whitney has designed, developed and tested the F135 to deliver the most advanced fifth generation fighter engine for the U.S. Air Force, Marine Corps and Navy, as well as eight international partner countries. The F135 is derived from proven technology of the only operational fifth generation fighter engine, the Pratt & Whitney F119. It has been further enhanced with technologies developed in several Air Force and Navy technology programs.

The F135 is the only engine powering the F-35 Lightning II flight test program. The F135 propulsion system has proven it can meet diverse aircraft requirements, and the ground and flight test experience demonstrates the maturity and the associated reliability of the F135 engine for armed forces around the world.

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.

Lockheed Martin debuts first F-35C for US Navy
By Stephen Trimble

Lockheed Martin has unveiled the first naval variant for the F-35 Joint Strike Fighter programme in a roll-out ceremony at its final assembly plant in Fort Worth, Texas.

'"It's an honour and a privilege and it is a great day", says Adm Gary Roughhead, chief of naval operations. The US Navy plans to operate 260 F-35C carrier variants among the 2,443 aircraft in the current US programme.

"This airplane will top anything that comes it's way," Roughead adds.

The first prototype CV model to roll off the production line - CF-1 - follows the debut of a conventional variant for the US Air Force in December 2006 and a short take-off and vertical landing F-35B in June 2008.

The naval variant uses the same propulsion system as the air force fighter, but adds other modifications, including an expanded wing and strengthened landing gear.

The F-35C will be the first tactical aircraft to enter naval service in the USA for several decades that is powered by a single engine. It will also be the first carrier-based jet fighter featuring all-aspect stealth.

The navy's first F-35C unit is scheduled to enter service in fiscal year 2015, although one Pentagon estimate projects a two-year delay.

The CF-1 prototype model is now expected to start flight tests in late December, reflecting a three-month schedule slip. It is projected to be the fourth F-35 prototype to enter flight test, following the non-production configuration AA-1, and STOVL aircraft BF-1 and BF-2.

F-35B Successful in First Probe-and-Drogue Aerial Refueling
Released on Friday, August 14, 2009

Lockheed Martin F-35 Successful In First Probe-And-Drogue Aerial Refueling

FORT WORTH, Texas, August 14th, 2009 -- A short takeoff/vertical landing (STOVL) variant of the Lockheed Martin [NYSE: LMT] F-35 Lightning II stealth fighter has become the first F-35 to complete an aerial refueling test using the Navy- and Marine Corps-style probe-and-drogue refueling system. Thursday's successful mission is the first in a short series of tests that will clear the STOVL F-35B variant for extended-range flights, particularly to its primary test site at Naval Air Station Patuxent River, Md.

"The F-35 program is on the cusp of a tremendous expansion in flight test as a large number of new aircraft enter the test fleet this year and early next year," said Dan Crowley, Lockheed Martin executive vice president and F-35 program general manager. "This milestone will help ensure that we fill the pipeline between Fort Worth and Pax River with F-35s and maintain our flight-test tempo."

During Thursday's flight, the F-35B designated BF-2 (the second STOVL flight test aircraft), began a series of tests in which fuel is uploaded into the aircraft at 10,000, 15,000 and 20,000 feet, at speeds ranging from 200 to 250 knots. The pilot on the initial F-35B aerial refueling flight was U.S. Marine Corps Maj. Joseph T. "O.D." Bachmann.

The refueling mission also marked the first time a Lockheed Martin KC-130J tanker has been used to refuel an F-35. Since deployment to Iraq in 2005 the KC-130J has offloaded more than 186 million pounds of fuel during combat operations. Previous refueling missions with the F-35A conventional takeoff and landing variant were accomplished with a KC-135 tanker. To date, the first F-35A has received approximately 110,000 pounds of fuel during aerial refuelings.

Probe-and-drogue refueling employs a flexible hose that trails from the tanker aircraft. The basketlike drogue at the end of the hose connects to the receiving aircraft's probe, which, in the case of the F-35, resides on the right side of the forward fuselage and retracts when not in use. The U.S. Navy, Marine Corps and the air forces of many other countries use the probe/drogue system, while the U.S. Air Force refuels its aircraft via a rigid flying boom that inserts into a receptacle on the receiving airplane.

The Lockheed Martin F-35 and F-22 are the world's only 5th generation fighters, uniquely characterized by a combination of advanced stealth with supersonic speed and high agility, sensor fusion, network-enabled capabilities and advanced sustainment. The three F-35 variants are derived from a common design, are being developed together and will use the same sustainment infrastructure worldwide, bringing economies of commonality and scale.

Lockheed Martin is developing the F-35 with its principal industrial partners, Northrop Grumman and BAE Systems. Two separate, interchangeable F-35 engines are under development: the Pratt & Whitney F135 and the GE Rolls-Royce Fighter Engine Team F136.
