  New policy addresses 3D parts for Army aircraft

  By Courtesy As the Army explores the potential of some advanced manufacturing methods and 3D-printed parts to maintain and sustain its aviation fleet, recently published guidance aims to strike a balance between safety, improvements to readiness and escalating costs. Advanced manufacturing refers to new ways of making existing products and the production of new products using advances in technology. Advanced manufacturing includes additive manufacturing, a process of joining materials to make parts from 3D-model data. Additive manufacturing differs from the traditional subtractive process that cuts away material to shape and produce parts. The U.S. Army Aviation and Missile Command recently published a policy memorandum addressing advanced manufacturing for Army aircraft parts, components and support products. “Evolving technologies create a unique challenge as we determine the airworthiness of parts when the data is immature, incomplete or even non-existent,” said AMCOM Commander Maj. Gen. Todd Royar, who serves as the Army's airworthiness authority, responsible for ensuring the safety of the service's aircraft components. As enduring aircraft, like the UH-60 Black Hawk helicopter, continue in service, the supply system with face challenges with obsolescence, meaning parts that are difficult to acquire or receive no bids from potential vendors to manufacture. As the Army keeps pace with technology, advanced manufacturing creates opportunities to optimize long-term sustainment efforts. The Army established a partnership recently with Wichita State University's National Institute for Aviation Research (NIAR) to create a “digital twin” of an aging Black Hawk model. “One of the primary tasks in this effort is to convert all legacy 2D drawings of this aircraft into modern 3D parametric models,” said John Tomblin, senior Vice-President for Industry and Defense Programs and Executive Director of NIAR at Wichita State University. “This will allow the Army to source parts that are out of production as well as use advanced techniques, such as additive manufacturing, to produce parts.” The digital twin opens a door to the 3D modeling and more opportunities to use parts made through additive manufacturing. The NIAR project is not the Army's only effort. Army Aviation is already using advanced manufacturing methods and 3D-printed parts to solve specific challenges. When several CH-47 helicopters experienced structural cracks at a certain portion of the frame assembly, an initial solution was to replace the entire frame assembly. “Replacing the entire assembly is a time-consuming task that also poses logistical challenges because replacements are difficult to obtain,” said AMCOM's Aviation Branch Maintenance Officer, Chief Warrant Officer 5 Michael Cavaco. Instead, engineers designed a solution to restore the cracked frames to their original strength by creating repair fittings using Computer-Aided Design models. “After five iterations of 3D-printing prototypes, test fit and model adjustments, a final design solution was achieved,” Cavaco said. Additionally, 3D printers have created several tools and shop aids that have benefitted the field. Many of these stand-alone items that support maintenance operations are authorized within Army technical manuals, depot maintenance work requirements or similar publications. While too early to predict overall cost and time savings, the advantages of advanced manufacturing are significant. The use of advanced manufactured parts will eliminate wait time on back-ordered parts that, ultimately, delay repairs. A key focus of AMCOM's AM policy is on inserting evolving technologies into enduring designs that have relied on traditional manufacturing processes throughout their acquisition lifecycle. However, future Aviation are benefiting as well from advanced manufacturing. The Improved Turbine Engine Program (ITEP) includes a number of advanced manufacturing elements. “ITEP benefits from advanced manufacturing include reduced cost, reduced weight, increased durability, and enhanced performance when compared to traditional manufacturing methods,” said Col. Roger Kuykendall, the project manager for Aviation Turbine Engines. “The benefits of AM stem from the unique capability to produce more complex hardware shapes while simultaneously reducing part count.” The fine details of airworthiness expectations asserted in this policy were crafted by a team of engineers at the U.S. Army Combat Capabilities Development Command Aviation and Missile Center, led by Chris Hodges, the current acting associate director for Airworthiness-Technology. Hodges said the new policy was drafted after his team collaborated with stakeholders from across the aviation enterprise, reaching across Army organizations and out to sister services and the Federal Aviation Administration. “We considered a lot of input and ultimately organized expectations and requirements by category, spanning from tools and shop aids to critical safety items,” Hodges said. “The resulting policy sets a solid foundation with room to grow and fill in details as the story evolves.” For Army aviation applications, advanced-manufactured parts and components will be managed under six categories that range from articles that support maintenance operations to those aviation critical safety items, whose failure would result in unacceptable risk. The designated categories prescribe for engineers and manufacturers the allowed materials and appropriate testing methodology for each particular part. The new guidance is not intended as a replacement for other existing policies that address advanced manufacturing. “We intend to be in concert with Army policies and directives that pertain to readiness, maintenance and sustainment,” Royar said. “Our policy provides a deliberate approach to ensure airworthiness and safety while determining where research and efforts may best supplement the supply chain and improve performance while balancing cost.” AMCOM Command Sgt. Major Mike Dove acknowledged the methodology must continue to mature in multiple areas before confidence grows in the ability to measure airworthiness qualification requirements for advanced-manufactured parts. “We fully support the maturation requirements for advanced-manufacturing technology, but not at the expense of flight safety,” Dove said. As Army aviation continues to pursue and include advanced-manufacturing methods, Royar noted the potential impact as the technology evolves. “Advanced manufacturing touches units, depots and the broader supply chain,” Royar said. “As we sustain our enduring aircraft and look to future systems, it is important that we keep pace with this and other emerging technologies for the sake of the warfighter.” https://www.army.mil/article/238868/new_policy_addresses_3d_parts_for_army_aircraft

  JUST IN: New Navy Lab to Accelerate Autonomy, Robotics Programs

  9/8/2020 By Yasmin Tadjdeh Over the past few years, the Navy has been hard at work building a new family of unmanned surface and underwater vehicles through a variety of prototyping efforts. It is now standing up an integration lab to enable the platforms with increased autonomy, officials said Sept. 8. The Rapid Integration Autonomy Lab, or RAIL, is envisioned as a place where the Navy can bring in and test new autonomous capabilities for its robotic vehicles, said Capt. Pete Small, program manager for unmanned maritime systems. “Our Rapid Autonomy Integration Lab concept is really the playground where all the autonomy capabilities and sensors and payloads come together, both to be integrated ... [and] to test them from a cybersecurity perspective and test them from an effectiveness perspective,” Small said during the Association for Unmanned Vehicle Systems International's Unmanned Systems conference, which was held virtually due to the ongoing COVID-19 crisis. Robotics technology is moving at a rapid pace, and platforms will need to have their software and hardware components replaced throughout their lifecycles, he said. In order to facilitate these upgrades, the service will need to integrate the new autonomy software that comes with various payloads and certain autonomy mission capabilities with the existing nuts-and-bolts packages already in the unmanned platforms. “The Rapid Autonomy Integration Lab is where we bring together the platform software, the payload software, the mission software and test them,” he explained. During testing, the service will be able to validate the integration of the software as well as predict the performance of the unmanned vehicles in a way that “we're sure that this is going to work out and give us the capability we want,” Small said. The RAIL concept will rely on modeling-and-simulation technology with software-in-the-loop testing to validate the integration of various autonomous behaviors, sensors and payloads, he said. “We will rely heavily on industry to bring those tools to the RAIL to do the testing that we require,” he noted. However, the lab is not envisioned as a single, brick-and-mortar facility, but rather a network of cloud-based infrastructure and modern software tools. “There will be a certain footprint of the actual software developers who are doing that integration, but we don't see this as a big bricks-and-mortar effort. It's really more of a collaborative effort of a number of people in this space to go make this happen," Small said. The service has kicked off a prototype effort as part of the RAIL initiative where it will take what it calls a “third-party autonomy behavior” that has been developed by the Office of Naval Research and integrate it onto an existing unmanned underwater vehicle that runs on industry-made proprietary software, Small said. Should that go as planned, the Navy plans to apply the concept to numerous programs. For now, the RAIL is a prototyping effort, Small said. “We're still working on developing the budget profile and ... the details behind it,” he said. “We're working on building the programmatic efforts behind it that really are in [fiscal year] '22 and later.” The RAIL is part of a series of “enablers” that will help the sea service get after new unmanned technology, Small said. Others include a concept known as the unmanned maritime autonomy architecture, or UMAA, a common control system and a new data strategy. Cmdr. Jeremiah Anderson, deputy program manager for unmanned underwater vehicles, said an upcoming industry day on Sept. 24 that is focused on UMAA will also feature information about the RAIL. “Half of that day's agenda will really be to get into more of the nuts and bolts about the RAIL itself and about that prototyping effort that's happening this year,” he said. “This is very early in the overall trajectory for the RAIL, but I think this will be a good opportunity to kind of get that message out a little bit more broadly to the stakeholders and answer their questions.” Meanwhile, Small noted that the Navy is making strides within its unmanned portfolio, citing a “tremendous amount of progress that we've made across the board with our entire family of UVS and USVs.” Rear Adm. Casey Moton, program executive officer for unmanned and small combatants, highlighted efforts with the Ghost Fleet Overlord and Sea Hunter platforms, which are unmanned surface vessels. The Navy — working in cooperation with the office of the secretary of defense and the Strategic Capabilities Office — has two Overlord prototypes. Fiscal year 2021, which begins Oct. 1, will be a particularly important period for the platforms, he said. “Our two Overlord vessels have executed a range of autonomous transits and development vignettes,” he said. “We have integrated autonomy software automation systems and perception systems and tested them in increasingly complex increments and vignettes since 2018.” Testing so far has shown the platforms have the ability to perform safe, autonomous navigation in according with the Convention on the International Regulations for Preventing Collisions at Sea, or COLREGS, at varying speeds and sea states, he said. “We are pushing the duration of transits increasingly longer, and we will soon be working up to 30 days,” he said. “Multi-day autonomous transits have occurred in low- and high-traffic density environments.” The vessels have already had interactions with commercial fishing fleets, cargo vessels and recreational craft, he said. The longest transit to date includes a round trip from the Gulf Coast to the East Coast where it conducted more than 181 hours and over 3,193 nautical miles of COLREGS-compliant, autonomous operation, Moton added. Both Overload vessels are slated to conduct extensive testing and experimentation in fiscal year 2021, he said. “These tests will include increasingly long-range transits with more complex autonomous behaviors,” he said. "They will continue to demonstrate automation functions of the machinery control systems, plus health monitoring by a remote supervisory operation center with the expectation of continued USV reliability." The Sea Hunter will also be undergoing numerous fleet exercises and tactical training events in fiscal year 2021. “With the Sea Hunter and the Overlord USVs we will exercise ... control of multiple USVs, test command-and-control, perform as part of surface action groups and train Navy sailors on these platforms, all while developing and refining the fleet-led concept of operations and concept of employment,” Moton said. https://www.nationaldefensemagazine.org/articles/2020/9/8/navy-testing-new-autonomy-integration-lab
