Les industriels de la Défense s’organisent pour produire plus vite

L'Etat, par la voix du Président de la République, ou celle du ministre des Armées, intimant aux acteurs industriels de la Défense d'accélérer leurs cadences de production, ceux-ci s'organisent pour apporter une réponse adéquate. Un exemple de ces délais jugés trop long, la production d'un radar militaire standard, une fois la commande passée, les pièces des sous-traitants réceptionnées, dure entre 24 et 36 mois, hors pénurie de matières. Au sein de la filière, donneurs d'ordre et sous-traitants planchent en toute discrétion pour proposer au ministre des Armées, Sébastien Lecornu, des leviers d'action applicables à court terme, en s'inspirant des méthodes de l'aéronautique civile. Une réflexion a lieu pour avoir des doubles sources sur certains composants, la norme dans le civil mais pas dans le militaire, et pour passer d'une logique de production à la commande, comme c'est le cas aujourd'hui, à une stratégie de flux. C'est une stratégie qui a aussi ses limites, le stockage de pièces ayant un coût significatif. Ainsi, une partie de la réponse se trouve du côté de l'industrie, mais l'autre est au niveau du ministère des Armées et de la Direction Générale de l'Armement (DGA). Les clients eux-mêmes vont sans doute devoir accepter de revoir les règles actuelles. Les tests pouvant durer 6 mois sur certains équipements, si les délais étaient revus à la baisse, il faudrait accepter un niveau de dysfonctionnements supérieur à la normale.

    Embraer Predicts E175-E2 First Flight By Year-End

    Helen Massy-Beresford Brazilian aircraft manufacturer Embraer expects the E175-E2 to make its first flight later this year, with an entry into service for the latest member of its new-generation E-Jets family expected at the end of 2021. Meanwhile, the E195-E2, Embraer's largest commercial aircraft, which offers up to 146 seats and boasts lower operating costs per seat, better fuel consumption and lower emissions, is partway through a global demonstration tour. The tour has just left Europe and is now in North America before heading to Africa next month. “The first prototype of the E175-E2 is being built, and the engine is being hung. We're looking forward to going into service at the end of 2021 and to the first flight at the end of this year,” Martyn Holmes, Embraer Commercial Aviation's VP for Europe, Russia, Central Asia and Leasing, told a press conference at the European Regions Airline Association general assembly Oct. 9. “I think there are great opportunities for the E175-E2 in western continental Europe, I think it will be a great hub feeder. We're stepping up our activity with airlines–watch this space.” As for the E195-E2, following certification by Brazilian, European and U.S. authorities in April, Embraer delivered its first aircraft Sept. 12 to Brazilian low-cost operator Azul, the type's global launch operator, and to lessor AerCap. The E195-E2 is due to enter service with Binter Canarias and Helvetic Airways in the next few weeks. Embraer Commercial Aviation CEO John Slattery also said the manufacturer is considering the turboprop market. “There's absolutely a place in the world for turboprops but the current technology for turboprops is over three decades old,” he said. “I do believe there is an opportunity to significantly improve the operations and the emissions against what's available in the market today in turboprops. “This is something we have been looking at now in earnest for quite some time. We're continuing to spend meaningful dollars in continuing our review. We're always running the ruler over what's next. We're also running the ruler over what should come after the turboprop: What should we be doing on electric hybrid or autonomous travel, for example. There's a role for turboprops, and I'd like to own a piece of that, but we haven't quite closed the business case yet.” Embraer has spoken to operators and lessors in the turboprop segment around the world who “uniformly” see a market for a new-technology turboprop that would yield reduced operating costs and emissions, Slattery added. https://aviationweek.com/crossover-narrowbody-jets/embraer-predicts-e175-e2-first-flight-year-end

    Iwakuni Marines use 3D printers to revolutionize maintenance for fighter jets

    By JAMES BOLINGER | STARS AND STRIPES MARINE CORPS AIR STATION IWAKUNI, Japan — Using 3D printers, Marines based in southern Japan created two products that reduce the time it takes to repair F/A-18 Hornets and may save the Defense Department money. Called an engine ship kit, the first innovation is a set of plastic clips and plugs to prevent oil and hydraulic fluid leaking from aircraft engines removed for repairs. The other is a tool that helps maintainers grease the bearings on the F/A-18's high-speed Gatling gun. Designed by Marines from MCAS Iwakuni's Marine Aviation Logistics Squadron 12, the engine ship kit will have an immediate impact on operations, squadron commander Lt. Col. Javier Garcia recently told Stars and Stripes. The kit eliminates the need for maintainers to travel to austere locations to drain oil and hydraulic fluids so an engine can be taken safely back to Iwakuni for repair. The plastic drain plugs prevent the fluid from leaking and the clips ensure the plugs are not dislodged as the engine is readied for transport. The kit is the brain child of 1st Lt. Simon Miller and Chief Warrant Officer 3 Mark Willems, who needed to get a broken F/A-18 engine from Wake Island to MCAS Iwakuni late last year. The engine began to leak while a C-130 crew tried to load it, Garcia said. In the past, a team of maintenance Marines would have traveled to the location to prepare the engine for safe transport, but that takes away from their mission at MCAS Iwakuni. To solve the problem, Willems had the idea of creating plugs that would stop the leaks. Miller created the pieces using 3D drafting software and MALS 12's new 3D printers. “I'm not really sure why no one thought to make this kind of kit before, but this design is going to have an impact across the Navy and Marine Corps,” Garcia said. The same team behind the engine ship kit also created a tool that makes it easier for maintenance Marines to grease the bearing on the F-18's M61A Vulcan, a Gatling-style rotary cannon that can fire 6,000 rounds a minute. The bearing on the cannon must be packed with grease every 30,000 rounds, a job that used to take two Marines more than 30 minutes, said Cpl. Christian Smellie, an aviation life-support systems technician who works at Iwakuni's 3D printing lab.
