Oerlikon is partnering with Boeing and Lufthansa Technik to research standardization and qualification of additive manufacturing processes.
Oerlikon is pairing up with major aerospace players to make additive manufacturing (AM) a more feasible option for industrialization. The Swiss technology and engineering group has signed agreements this year with Lufthansa Technik (LHT) and Boeing to collaborate on research into ways AM for aerospace can be more easily standardized and qualified.
The most recent of these agreements is the memorandum of understanding (MoU) with LHT, which aims to establish “robust and repeatable processes for AM in the aircraft MRO industry.” According to a spokesperson for Oerlikon, the collaboration's research seeks to understand what process variability exists when the same component geometries are built on the same machine using the same powder batch, heat treatment, testing conditions and build parameters in different global locations. Oerlikon and LHT will print these components using an Oerlikon-produced IN718 powder alloy on identical printers at LHT Hamburg and Oerlikon's locations in Charlotte, North Carolina and Barleben, Germany.
Once the variables are identified, the study's objective is to understand how they can be controlled to achieve repeatable processes—which will ensure that all parts meet quality requirements and reduce the cost of recurring quality validation, according to Oerlikon. The company says this repeatability could also provide potential savings in procurement, warehousing and supply chain management. For now, the partnership is set for a one-year period, but the companies say the scope and timeframe is likely to increase.
Meeting the challenges of qualifying AM materials and processes for aerospace is also at the heart of Oerlikon's collaboration agreement with Boeing. The five-year agreement, which was signed in February, seeks to develop standard materials and processes for metal-based AM. The collaboration's research will initially focus on industrializing titanium powder bed fusion AM. The companies say that in addition to meeting qualification challenges, it will enable them to “provide a route for the adoption of AM with a qualified supply chain that achieves quality and cost targets.”

By: Valerie Insinna WASHINGTON — The Super Hornet is set to meet the 80 percent mission capable rate goal by the end of the year, the Pentagon's top civilian said Wednesday, but it remains unclear whether the F-35, F-22 and F-16 will be able to meet the mark. Last fall, former Defense Secretary Jim Mattis gave the Air Force, Navy and Marine Corps until the end of fiscal year 2019 to bring their F-35s, F/A-18E/F Super Hornets, F-22 Raptors and F-16s up to an 80 percent mission capable rate — a key metric to determine the health of a flying squadron's aircraft. Of those, the “real emphasis was on the F-35 and F/A-18,” acting Defense Secretary Pat Shanahan said May 1 during a House Appropriations Committee panel, and the Super Hornet has made a “tremendous” amount of headway over the past year. “The Navy has made significant progress with the F/A-18s. I think they're on track to meet the goal in September,” he told lawmakers. However, Shanahan suggested that the F-22 and F-16 are unlikely to hit the 80 percent goal, adding that the F-22 “has struggled” and the F-16 “is a bit of a high bar” to clear. Shanahan was unclear on whether the F-35 — which is available in three different variants used by the Air Force, Marine Corp and Navy — will be able to meet the mandate this year. “The F-35s, being brand new aircraft, that [80 percent] should be the baseline where we start,” he said. “The F-35 will come home. We're going to drive that home.” The Air Force, Navy and Marine Corps didn't not provide information about the F-35's progress by press time, but the most recent statistics do not seem promising. The services have stopped publishing mission capable rate statistics last year, citing operational sensitivities, but a March report by the Government Accountability Office found that all variants of the F-35 operated at a mission capable rate of about 50 percent from a period of May to November 2018. However, Mattis' mandate specifies that only the F-35s used by operational squadrons must meet the readiness marker. Because there are only a small number of operational F-35 squadrons, and those units typically have newer and more reliable aircraft, the services may stand a better chance of getting to the 80 percent rate. Air Force spokeswoman Ann Stefanek concurred with Shanahan's assessment of the F-16 and F-22, saying that damage from Hurricane Michael to Tyndall Air Force Base's F-22s and ongoing difficulties with maintaining the F-22's low observable coating were likely to prevent the Raptor from achieving an 80 percent mission capability rate this year. However, the service is still “optimistic” that it will be able to get its F-16s over the finish line by the end of FY19, she said. Given the low availability of tactical aircraft in recent years, it would be a massive accomplishment to get any of the fighter jets to meet the 80 percent goal. In August, Navy Secretary Richard Spencer told reporters that half of the service's Super Hornet aircraft were mission capable — a huge increase from 2017 when two-thirds of the fleet were not available to fly. In 2017, the last year the Air Force put out data, F-22s held a 49 percent mission capable rate and the F-16 hovered around 65 to 70 percent, depending on the model. Despite the services' difficulties meeting the aviation readiness goal, Shanahan maintained that pushing toward an 80 percent mission capable rate for those platforms was a worthy endeavor. “It's a lot of iron to keep on the ground, and given all the training missions and the productivity we can generate, I think holding that standard is smart for now,” he said. https://www.defensenews.com/digital-show-dailies/navy-league/2019/05/01/shanahan-super-hornet-on-track-to-meet-readiness-goals-but-f-16s-and-f-22s-still-struggling
