Saab fait voler une pièce de fuselage d’avion de combat imprimée en 3D

Le constructeur suédois Saab est parvenu, pour la première fois, à faire voler un avion équipé d'une pièce extérieure imprimée en 3D. L'avionneur utilise la technologie de la fabrication additive depuis quatre ans, notamment pour imprimer des pièces internes, précise L'Usine Nouvelle. La pièce, une trappe située sur le flanc arrière du fuselage de l'appareil, un modèle Gripen, a été imprimée sur la base du scan de la pièce originelle. Parfaitement ajustée à l'avion, elle n'a montré « aucun changement structurel visible après le vol d'essai », assure Hakan Stake, responsable du projet, dans un communiqué. Cette démonstration devrait, à terme, « permettre au personnel sur le terrain d'avoir accès à des pièces de rechange ajustées individuellement, d'éviter les réparations d'urgence ou de cannibaliser un appareil déjà endommagé », souligne-t-il. Il estime par ailleurs que cette solution permettra de réduire le nombre de pièces transportées lors du déploiement d'un appareil et de réduire son temps de réparation. De nombreuses étapes de certification du matériau utilisé, un polyamide 2200, couramment utilisé dans la fabrication additive, sont encore nécessaires avant de déployer la technologie sur le terrain.

    PENTAGON AND LOCKHEED MARTIN AGREE TO REDUCED F-35 PRICE IN NEW PRODUCTION CONTRACT

    F-35A Aircraft Now Below $90 Million FORT WORTH, Texas, Sept. 28, 2018 /PRNewswire/ -- The U.S. Department of Defense and Lockheed Martin (NYSE: LMT) have finalized an $11.5 billion contract for the production and delivery of 141 F-35 aircraft at the lowest per aircraft price in program history. For the eleventh consecutive year, the cost of an F-35A was lowered. The F-35A unit price including aircraft, engine and fee, is $89.2 million. This represents a 5.4 percent reduction from the $94.3 million it cost for an F-35A in Low-Rate Initial Production Lot 10 (LRIP 10). In LRIP 11, the F-35B unit cost was lowered to $115.5 million. This represents a 5.7 percent reduction from the $122.4 million it cost for the short-takeoff and landing variant in LRIP 10. The F-35C unit cost was lowered to $107.7 million. This represents an 11.1 percent reduction from the $121.2 million it cost for the carrier variant in LRIP 10. The LRIP 11 agreement funds 91 aircraft for the U.S. Services, 28 for F-35 International Partners and 22 for F-35 Foreign Military Sales customers. Deliveries will begin in 2019. "Driving down cost is critical to the success of this program," said Vice Admiral Mat Winter, F-35 Program Executive Officer. "We are delivering on our commitment to get the best price for taxpayers and warfighters. "This agreement for the next lot of F-35s represents a fair deal for the U.S. Government, our international partnership and industry. We remain focused on aggressively reducing F-35 cost and delivering best value." With stealth technology, supersonic speed, powerful sensors, large weapons capacity and global deployment, the F-35 is the most advanced fighter aircraft ever built, enabling women and men in uniform to execute their mission and return home safely. More than a fighter jet, the F-35's ability to collect, analyze and share data, is a powerful force multiplier that enhances all airborne, surface and ground-based assets in the battlespace. "This agreement marks a significant step forward for the F-35 program as we continue to increase production, reduce costs and deliver transformational capabilities to our men and women in uniform," said Greg Ulmer, F-35 Vice President and General Manager. "As production ramps up, and we implement additional cost savings initiatives, we are on track to reduce the cost of the F-35A to $80 million by 2020, which is equal to or less than legacy aircraft, while providing a major leap in capability." Program Progress The latest contract is a demonstration of the program's progress and maturity, as industry and the government now set their sights on future acquisition approaches for the next three production lots to further reduce costs. With more than 320 aircraft operating from 15 bases around the globe – the F-35 is playing a critical role in today's global security environment. More than 680 pilots and 6,200 maintainers have been trained and the F-35 fleet has surpassed more than 155,000 cumulative flight hours. The F-35 weapons system reliability continues to improve through a combination of hardware and software improvements. In addition to advanced capability, the F-35 provides economic stability to the U.S. and Allied nations by creating jobs, commerce and security, and contributing to the global trade balance. The F-35 is built by thousands of men and women in America and around the world. With more than 1,500 suppliers in 46 states and Puerto Rico, the F-35 program supports more than 194,000 direct and indirect jobs in the U.S. alone. The program also includes more than 100 international suppliers, creating or sustaining thousands of international jobs. About Lockheed Martin Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 100,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. This year the company received three Edison Awards for ground-breaking innovations in autonomy, satellite technology and directed energy.

    Turkey to Rolls-Royce: Let’s renegotiate terms for TF-X fighter jet support

    By: Burak Ege Bekdil ANKARA, Turkey — The Turkish government is keen to revive talks with Rolls-Royce for the design and production of its first indigenous fighter jet, the TF-X, a top cabinet minister has said. Foreign Minister Mevlüt Çavuşoğlu said the government wants to move forward with its planned cooperation with Britain for the production of the new-generation aircraft. But Turkey must first select an engine for the TF-X and then finalize the aircraft's full design — a process that has has lagged behind schedule. Its aerospace and procurement officials now aim to fly the TF-X in the 2025-2026 time frame, despite an original target of 2023. A £100 million (U.S. $132 million) deal between Rolls-Royce and Turkish manufacturer Kale Group was effectively put on hold amid uncertainties over technology transfer. In October 2016, Rolls-Royce offered a joint production partnership to Turkey to power Turkey's planned platforms. The offer also involved potential sales to third parties. The British company's proposal also included a production unit in Turkey to manufacture engines for the TF-X, as well as for helicopters, tanks and missiles. A year before that, in October 2015, a memorandum of understanding was signed between Turkey and Rolls-Royce for technological know-how and a production unit. Under the plan, Rolls-Royce would launch an advanced manufacturing and technology center in Turkey ― the company's eighth such unit worldwide. Also in 2017, BAE Systems and Turkish Aerospace Industries, the prime contractor of TF-X, signed a $125 million heads of agreement to collaborate on the first development phase of the planned fifth-generation fighter jet. After its membership in the U.S.-led, multinational Joint Strike Fighter program was suspended, Turkey started to look for alternatives for an off-the-shelf bridge gap solution until its own fighter jet can be built. Talks with Russia are underway for a potential Su-35 or Su-57 deal, according to officials in Ankara and Moscow. https://www.defensenews.com/industry/2019/12/12/turkey-to-rolls-royce-lets-renegotiate-terms-for-tf-x-fighter-jet-support
