  Despite progress, industry faces ‘very tough roadmap’ to field FCAS by 2040

  By: Vivienne Machi   STUTTGART, Germany — After the decade that has been the year 2020, it may seem like 2040 is centuries away. But for Airbus, the scheduled in-service date for Europe's next-generation combat aircraft and weapon system feels just around the corner. The Future Combat Air System (FCAS) industry partners have made significant progress on the pan-European, multi-system effort despite the hurdles of the COVID-19 pandemic. However, Airbus, along with its co-contractors Dassault Aviation and Indra, face a “very tough roadmap” to finalize system designs, begin preliminary development, launch production, and get the systems into service, said Bruno Fichefeux, FCAS leader for Airbus, during the company's annual trade media briefing Dec. 9. The 18-month Joint Concept Study and Phase 1A of the demonstrator portion are progressing well, but the companies need to move quickly to reach key technology maturation phases, he said. “This is a major de-risking and speeding approach towards the future development program, to ensure that we are on time on expectation.” France, Germany and Spain have teamed up on the FCAS program, which includes seven next-generation technology pillars: a sixth-generation fighter jet, multiple “remote carrier” drones, a next-generation weapon system, a brand new jet engine, advanced sensors and stealth technologies, and an “air combat cloud.” In September, the nations' three air forces worked together to down-select the five preferred architectures that will help inform the program's follow-on phases, Fichefeux said at the virtual briefing. The goal for 2021 is for FCAS to enter the preliminary demonstrator development phase for the next-generation fighter and the remote carrier aircraft. Those contracts are currently in negotiations, he noted. Starting in 2021, the FCAS will go from spending a “few million” euros to “billions,” he added. “It's a massive step forward [that] we want to initiate next year.” Observers can expect to see some major design choices after those negotiations are complete; for example, whether the next-generation fighter will have one or two seats, Fichefeux said. Airbus' unmanned aerial systems team has moved forward with efforts related to the remote carrier and manned-unmanned teaming technologies. Jana Rosenmann, the company's UAS leader, said at the briefing that her team had submitted their proposal for Phase 1B of the FCAS demonstrator portion that is scheduled to begin next year. The team is studying two remote carrier designs. “We are looking at both a smaller, expendable remote carrier, as well as a larger, conventional-sized remote carrier, looking in the direction of a loyal wingman to fly together with the combat aircraft,” Rosenmann said. Airbus is the lead contractor for the remote carrier pillar. The program has some new partners on board, Fichefeux shared Wednesday. In April, Airbus teamed up with the German Ministry of Defence for an eight-month pilot program bringing non-traditional startups and research institutes into the FCAS fold. Eighteen organizations worked on 14 separate program elements, spanning the entire range of technology pillars. Those efforts have led to concrete results, to include a first flight-test-approved launcher of an unmanned aerial system from a transport aircraft; a secure combat cloud demonstrator; and a demonstrator of applied artificial intelligence on radio frequency analysis. These 18 partners could be picked up for subcontracts later on in the program, Fichefeux noted. The plan is to “mature these pilots step by step, and then it could develop into real contracting participation within the FCAS development,” he said. “There is a perspective to bring them on board at a later stage.” Meanwhile, Airbus also announced Wednesday that its Spanish subsidiary was selected as lead contractor for the low-observability pillar of the program. Airbus Spain will also lead Madrid's contribution to the next-generation fighter pillar. Indra serves as national lead for the entire program since Spain joined FCAS in early 2020, and also heads the sensor pillar while contributing to the combat cloud and simulations efforts. The finalization of the low-observability contract “completes Spain's onboarding as an equal nation across all FCAS activities,” Airbus said in a release. “The signature closes a ten-month process of onboarding Spain as the third nation.” The program will begin testing low-observability technologies early in the demonstrator phase, Fichefeux confirmed. Both the fighter aircraft demonstrator and the remote carrier will have stealth capabilities when they begin flight tests, which are expected as early as 2026. Then the team will need to work on issues such as how to factor in the future engine's heat signature, and how to integrate sensors and antennae, Fichefeux said. Low-observability “is part of almost all pillars, and the aim of this maturation is to prove” what works and what won't work, he noted. Along with a personal deadline, the FCAS program may also face schedule pressure from Europe's second sixth-generation fighter program. The United Kingdom, Italy and Sweden have teamed up on the Tempest program, with a current goal of delivering new fighter aircraft to the nations' militaries by 2035. When asked whether the two fighter programs may converge at some point, Fichefeux noted that that would ultimately be a government decision. “That is our responsibility, on the industry side, is just not to lose time waiting,” he said. “If the governments want to define a path of convergence, we will support it in due time.” https://www.defensenews.com/global/europe/2020/12/09/despite-progress-industry-faces-very-tough-roadmap-to-field-fcas-by-2040/

  How the Navy can lean in to software superiority

  Andrew C. Jarocki The Navy needs to take a "hard look” at its digital needs according to a senior Navy software official, especially in technology such as machine learning and artificial intelligence, or risk vital weapons systems failing on the future battlefield. Attendees of the Amazon Web Services Public Sector Summit in Washington June 21 heard warnings that obsolete and slow approaches are driving up costs of time and resources for the Navy's newest technologies that interact with one another in combat. "It's really a matter of making System A talk to System B,” said Richard Jack, a lead engineer and project director at the Space and Naval Warfare Systems Center Pacific. “A logistics system that needs to be able to interact with a weapons system.” Software superiority is an important part of the Navy's plan for a global competitive edge, from unmanned underwater vehicles to drones operated from ships. Unless the Navy wants to get an error message at a crucial combat moment, they will have to search outside their own technology labs for the solution to the interoperability challenge, Jack said. “The Navy can't do this alone, as 99 percent of the brain trust is in the cloud service providers and the industry,” Jack stated. He expressed the need to “take advantage” of lessons learned by cloud industry leaders on big data collection and interpreting results to make predictions . Jack suggested accelerating operations with increased cloud computing, creating shared infrastructure to make sure data centers are connected, eliminating duplicative investments across some programs, and further expanding AI and machine learning advancements. The software engineer expressed confidence that learning from cloud service providers will result in the Navy enhancing warfighting abilities, envisioning a cloud to allow instant data sharing “between a weapons system, an airframe, a UAV, and a logistics system” at the same time. Jack also praised cloud computing as important to the “compile to combat” program, in which the Navy is experimenting with ways to deploy new software capabilities to ships at sea in less than 24 hours. While the cloud can “be super fast and super efficient” for accessing large amounts of data anywhere, Jack also promised that it also allows the Navy to “really push the boundaries of machine learning,” even though “we are behind the curve” at the moment. Through “strategic partnerships” with the “Amazons, Googles and IBM Watsons of the world,” Jack promised the Navy could accomplish even more in the areas of AI and machine learning that will dominate warfighting in the era of the cloud. https://www.c4isrnet.com/it-networks/2018/06/25/how-the-navy-can-lean-in-to-software-superiority/

  Sikorsky ratchets up robotic control of Black Hawk in runup to pilotless flight

  Sikorsky has dialed up the autonomous flight control system on an experimental UH-60A Black Hawk to where a pilot can “set it and forget it” during long surveillance missions, another step toward flying the aircraft remotely from the cabin or from the ground without pilots on board. To date, Sikorsky has put 54.5 flight hours on its optionally piloted vehicle (OPV) flight control system, which is designed as a kit that replaces all legacy mechanical controls in existing aircraft with its MATRIX autonomous fly-by-wire controls. It has also run about 30 hours on the ground in the UH-60A, one of the oldest Black Hawks in the Army's inventory, according to chief test pilot Mark Ward. During the first of MATRIX in a Black Hawk in May, Sikorsky focused on the direct mode control scheme, which means the fly-by-wire controls should fly and respond to pilot input like a conventional UH-60 Black Hawk, Ward said. Technically, the mode is “direct stick-to-head with stability augmentation in the loop.” “Direct mode is supposed to be, more-or-less the service mode or an emergency mode, but we found the aircraft behaved quite well throughout all the speed regimes in that mode,” he said. Sikorsky briefly paused the flight test program to “fine tune” some of the pilot control augmentation modes, “so that when we go to autonomy we're going to have a very mature system that goes from full-spectrum of pilot 100 percent in the loop, to autonomy 100 percent in the loop and everywhere in between,” he said. Test pilots have since ratcheted up computer control of the aircraft and expanded the flight envelope out to 150 knots indicated airspeed. Most interestingly, the test team is beginning to increase the level of flight control augmentation beginning with “direct mode.” In “rate command attitude hold” mode, the fly-by-wire system takes over more control of the aircraft, Ward said. That mode was tested through low-speed hover maneuvers out to 150 knots. “When you put a control input, you're controlling a rate or an attitude change and when you release the control, you're capturing that attitude,” he said. From there, test pilots increased autonomous control of the aircraft to the full authority control scheme, or FACS, in which “rather than commanding a rate, you're actually commanding a parameter, such as airspeed or altitude or heading using the control stick,” Ward said. “To change from one mode to the next is simply a button push away to go from direct to rate command, up to FACS and back down,” he said. “Think of full authority as being an ultra-stable ISR platform that is going to be holding flight parameters for very long periods of time,” he said. “You kind of want to set it and forget it. You're not turning knobs on a flight director. You are actually flying the aircraft with the control stick.” “Rate command is when you kind of want to . . . throw it around a little bit, you want to do some low-and-slow or low-and-fast maneuvering where you're going from stop to stop to complete a mission.” Sikorsky uses the phrase “optimally piloted vehicle” as well as “optionally piloted vehicle” when discussing OPV and MATRIX because the ultimate goal is to develop a system that can act as an autonomous co-pilot quietly but constantly aiding human operators during specific missions. The OPV kit is tailored to the UH-60, but is retrofittable onto the Army's entire helicopter fleet and Sikorsky's commercial S-92 and S-97 rotorcraft, according to Igor Cherepinsky, the company's director of autonomy. Sometime in 2020, Sikorsky will demonstrate that the system can be remotely piloted from both inside and outside the aircraft, he said. “We will show the world this system is capable of being operated from the ground,” he said. Sikorsky continues to demonstrate MATRIX on a modified S-76B called the Sikorsky Autonomy Research Aircraft (SARA). The aircraft, which has been in test since 2013, has more than 300 hours of autonomous flight. The company announced in March that its S-92 helicopter fleet update will include the introduction of phase one MATRIX technology, which will allow for autonomous landing. The U.S. Army has plans to outfit a UH-60M with the system but is about six months behind Sikorsky's OPV test program. “Our vision is, obviously, not to replace the pilots, but to augment the pilots,” Cherepinsky said. “Once we field the technology, we never want to see another controlled flight into terrain or degraded visual environment issue accident ever happen with any of our aircraft.” https://www.verticalmag.com/news/sikorsky-ratchets-up-robotic-control-of-black-hawk-in-runup-to-pilotless-flight/
