COVID-19 Forces USN To Expedite USAF Workshare Agreement

Lee Hudson

The U.S. Navy has expedited its component workshare agreement with an Air Force aviation depot because of coronavirus-related workforce shortages.

Fleet Readiness Center East (FRCE) located in North Carolina was initially scheduled to begin working on a Boeing F-18 cabin safety valve later this year while the Oklahoma City Air Logistics Complex's test chamber was closed for scheduled maintenance. But the time line was accelerated when Tinker AFB in Oklahoma had a significant number of workers unavailable due to COVID-19 risk mitigation efforts.

The cabin safety valve is an integral part of the aircraft's environmental control system, Mary Linton, an aerospace engineer on the Gas Turbine Compressor-Pneumatics Fleet Support Team at FRCE, said in an April 27 statement. The valve is a component on both legacy F/A-18 Hornets and newer Super Hornets that acts as a backup to maintain cabin pressure above 23,000 ft. The part also serves as a supplement to the cabin air pressure regulator when the aircraft is in a rapid dive.

“The original intent of bringing this workload to FRCE was to support Tinker Air Force Base through a major support equipment rework effort,” Linton said. “All of the great effort that went into establishing this capability proved even more critical to maintaining the readiness of the F-18 fleet as we navigate through the COVID-19 crisis.”

The FRCE team was prepared to begin repairing, checking and testing the cabin safety valves in May, beginning with 20 per month before getting to a monthly rate of 40 by July, said John Miller, a planner and estimator with the Maintenance, Repair and Overhaul Logistics department at FRCE.

To date, FRCE has completed 18 of the 40 units inducted so far, with plans to funnel 10 more into the pipeline. Once those first units are completed, the team must wait for additional valves to maintain the workflow.

“The availability of components is still in flux due to COVID-19 and other factors, but the transition should move smoothly,” Miller said.

  • What to expect from AI, space and other tech over the next 18 months

    What to expect from AI, space and other tech over the next 18 months

    By: Aaron Mehta What will the next 18 months mean for the Pentagon's ongoing challenge to maintain a technological edge over its enemies? That was the question posed to a panel of experts at the 17th annual C4ISRNET conference Thursday. And the answers underline just how wide the technical areas of expertise are that Pentagon officials need to get their heads around in the modern era — and how the situation will remain fluid going forward. For Richard Linderman, deputy director for research and engineering in the Office of the Assistant Secretary of Defense, the focus is on manufacturing the vital microelectronics that provide the base for all of America's high-end technologies. He predicts a push to create those chips at a higher rate domestically, which in turn would allow greater trust that the chips, forming the basis of communications equipment or artificial intelligence, would not be messed with by a foreign entity. Concern about the domestic production of microelectronics is expected to be part of a large defense industrial base review now underway. “If you're right out on the pointy end of the spear, you might not want chips made in China to be the foundation of your communications gear,” Linderman told the audience. “So I think you're going to see those kinds of investments increase dramatically, and it will be an exciting prospect for us to bring new dimensions to this discussion of trusted, assured microelectronics.” James Hasik, a professor at the National Defense University, said he would be keeping a close eye on how the autonomous Sea Hunter vehicle does during ongoing testing. DARPA recently transferred the Sea Hunter, designed to travel thousands of miles over open seas, for months at a time, without a crew member on board, over to the Navy for continued testing. “The economics of that concept are so compelling,” Lungu said. If the concept proves out, it could have “some profound applications for fleet structure, some profound applications for warfighting.” Clark Groves, a space expert also at NDU, predicted that the long-awaited boom in small satellites will finally reach critical mass in the near-future, driven by the desire to move the massive telecommunications market onto cheaper systems. DoD stands to benefit, as this would be happening at the same time the Pentagon seeks to move from relying on massive, expensive aggregated systems towards a disaggregated model relying on multiple cheap, smaller systems — which present more of a challenge for any enemy nation that may seek to take out American assets in space. “Once small satellites begin being produced in large numbers, that will fundamentally alter the industrial base of the status quo, and that will also affect the launch base,” Groves said, which in turn “will give opportunities to DoD for more effective per-cost basis to exploit the architecture that we need for resilience.” Finally, Ed Brindley, acting deputy chief information officer for cybersecurity at the Pentagon, pointed to a “more determined focus” inside the Pentagon to shift how it handles artificial intelligence. At the core of that, he said, is the upcoming AI Center of Excellence, which Deputy Secretary of Defense Patrick Shanahan predicted will be up and running in the next six months. “Part of what we will see will be opportunities for us to adopt some of what is occurring within industry today,” Brindley said, noting that AI isn't just for warfighting but could have massive impacts on the internal processes of the Pentagon, including in the medical and legal professions. https://www.c4isrnet.com/show-reporter/c4isrnet-conference/2018/05/10/what-to-expect-from-ai-space-and-other-tech-areas-over-the-next-18-months/

  • Bell Invictus to Offer Army ‘Lower-Risk Path’ to FARA Capabilities

    Bell Invictus to Offer Army ‘Lower-Risk Path’ to FARA Capabilities

    By Brian Garrett-Glaser ARLINGTON, Texas — Bell's offering for the Army's Future Attack Reconnaissance Aircraft (FARA) contest, the 360 Invictus, is intended to offer the Army an insurance policy by presenting a lower-risk path to the capabilities it hopes to acquire as a “knife fighter” light attack helicopter to replace the retired OH-58 Kiowa Warriors. The Invictus, with its low-drag tandem cockpit design, draws from a lot of the development Bell has put into the 525 Relentless, a super-medium utility aircraft it hopes will be the first fly-by-wire rotorcraft certified for the civil market. Though Bell's FARA program is newer than some of its competitors, such as Sikorsky's S-97 Raider — Bell officials said the program had just three employees at this time last year and now comprises over 200 — the company believes its reliance on systems which it already has at a high technology readiness level due to work on the 525 will provide the Army with a compelling aircraft inside of its cost and timeline objectives. “It's still a very advanced aircraft. But by using technologies that we already had high TRLs in, or high manufacturing readiness levels in, we are ahead on that timeline piece,” Frank Lazzara, director of advanced vertical lift systems, told Avionics International during a press visit to the company's Flight Research Center here. The Invictus design meets or exceeds Army requirements in every area, according to Lazzara, due in part to the clean-sheet engineering that went into the Bell 525, including in the main and tail rotor systems. That aircraft has flown in excess of 200 knots without issue, despite being designed for 160 knots cruise speed. Bell intends the Invictus to cruise efficiently at 180 knots. “We flew [the 525] until we said we're done, but that rotor wasn't done,” said Josh O'Neill, senior manager for technology and evaluation on the Bell 525 program. “So we went not just 201 knots. It was a good bit more than that.” The 525 Relentless was the first aircraft Bell designed “totally in the 3D space,” O'Neill said, and the Invictus is similarly using a digital thread, enabling things like virtual reality maintaining exercises to provide design feedback without a physical product. “You have a digital thread, the same part that's used when you design your aircraft is used in the maintenance training, used throughout the product,” said O'Neill. “You design the aircraft in 3D, lay out all the systems and you're able to go in there with an actual maintainer. So we pulled [a line maintainer] and had him put the gloves on and go maintain the aircraft. And you can see in the 3D space, I need to reach around this piece, I need to turn my hand in a way that the human hand doesn't like to be turned. So we need to move that item.” As a fly-by-wire aircraft designed with a modular open systems architecture (MOSA) approach, Bell believes Invictus will provide the Army with an path to autonomy — or enable a single person in the aircraft to focus on mission functionality — similar to Bell's approach with the V-280 Valor, its offering for the Future Long-Range Assault Aircraft (FLRAA) competition. Bell officials said they are currently introducing autonomous flight software and performing software regression tests for that aircraft and intend to begin autonomous flight tests within the next few months. In March 2020, when the Army narrows the FARA competition from five companies to two, Bell's team will be nine months into design. After that, two of the five designs — selected from Sikorsky, Bell, Karem Aircraft, AVX/L3Harris, and Boeing — will be selected to participate in a fly-off slated for the second half of 2022. The Army hopes to field the first FARA aircraft in 2028. https://www.aviationtoday.com/2019/12/15/bell-invictus-offer-army-lower-risk-path-fara-capabilities/
