Les Royal Marines testent une combinaison volante (« jet pack »)

Les forces navales anglaises ont testé l'utilisation d'une combinaison volante, ou « jet pack », pour une manœuvre d'embarquement sur un bateau patrouilleur. La startup britannique Gravity Industries a développé un système de propulsion composé de cinq mini-réacteurs alimentés en kérosène : deux à chaque bras et un dans le dos. Le système a été testé en pleine mer début mai. « Bien qu'il soit sans aucun doute impressionnant, les experts ont conclu que le kit n'est pas encore prêt pour une utilisation militaire », a précisé la Royal Navy, qui souhaite observer avec un « intérêt constant » les futurs développements de la combinaison volante.

    KC-46 cargo solution still ‘months’ away

    By: Aaron Mehta and Valerie Insinna WASHINGTON — The U.S. Air Force expects to resolve a safety issue with the cargo capability of its KC-46A Pegasus tanker within “months,” the service's top acquisition official said Tuesday. Will Roper said he is “confident” the issue would get fixed and that the problem,— which has led the Air Force to stop the tankers from flying with cargo in their holds — was not his top concern for the Boeing-made plane. “The issue with the locks was identified. We're working options currently with Boeing and their supplier,” Roper said at a breakfast hosted by the Defense Writers Group. “We're looking to our operators to tell us which one of the solutions that have been identified is the one that they prefer." In September, Defense News first reported that the KC-46 was restricted from carrying either cargo or people in the back of the aircraft. The restriction was set after a recent flight where cargo locks on the bottom of the aircraft's floor became unlocked, creating concerns that airmen could be hurt or killed by heavy equipment that suddenly bursts free during a flight. It has been a rough year for the KC-46. The Air Force suspended KC-46 flights at Boeing's production line in Everett, Washington, this February after finding debris. Then it paused all tanker deliveries in March as the service investigated the extent of the problem. The service began accepting tankers again later that month, only for deliveries to stop — and restart — in April due to similar problems. The cargo issue represents the fourth category 1 deficiency for the tanker, and the issues are becoming increasingly expensive for Boeing: The company is locked into a fixed-price contract, which means it is responsible for paying for a expenses beyond the initial $4.9 billion award for development of the aircraft. So far, the company has paid more than $3.5 billion of its own money to fund corrections to ongoing technical issues. The other three issues are: The remote vision system, or RVS — the camera system that allows KC-46 boom operators to steer the boom into a receiver aircraft without having to look out a window and use visual cues — provides imagery in certain lighting conditions that appears warped or misleading. Boeing has agreed to pay for potentially extensive hardware and software fixes, but the Air Force believes it could be up to four years until the system is fully functional. The Air Force has recorded instances of the boom scraping against the airframe of receiver aircraft. Boeing and the Air Force believe this problem is a symptom of the RVS' acuity problems, and that the problem will be eliminated once the camera system is fixed. Boeing must redesign the boom to accommodate the A-10 plane, which currently does not generate the thrust necessary to push into the boom for refueling. This problem is a requirements change by the Air Force, which approved Boeing's design in 2016. Last month, Boeing received a $55.5 million contract to begin work on the new boom actuator. Roper said the cargo issue “goes into the kind of normal deficiency space” and noted that it's the type of issue that is discovered by the normal testing process. The more long-term issues, such as the remote visual system, are “the areas I keep the most focus on,” he said. https://www.defensenews.com/air/2019/11/12/kc-46-cargo-solution-still-months-away/

    AI Copilot: Air Force Achieves First Military Flight With Artificial Intelligence

    Signaling a major leap forward for national defense in the digital age, the Air Force flew with artificial intelligence as a working aircrew member onboard a military aircraft for the first time Dec. 15. The AI algorithm, known as ARTUµ, flew with the pilot, U.S. Air Force Maj. “Vudu”, on a U-2 Dragon Lady assigned to the 9th Reconnaissance Wing at Beale Air Force Base. Air Combat Command's U-2 Federal Laboratory researchers developed ARTUµ and trained it to execute specific in-flight tasks that otherwise would be done by the pilot. The test flight was the result of years of concerted effort within the Air Force to apply cutting-edge technology to military operations as it competes with other world powers in the digital age. “ARTUµ's groundbreaking flight culminates our three-year journey to becoming a digital force,” said Dr. William Roper, assistant secretary of the Air Force for acquisition, technology and logistics. “Putting AI safely in command of a U.S. military system for the first time ushers in a new age of human-machine teaming and algorithmic competition. Failing to realize AI's full potential will mean ceding decision advantage to our adversaries.” During this flight, ARTUµ was responsible for sensor employment and tactical navigation, while the pilot flew the aircraft and coordinated with the AI on sensor operation. Together, they flew a reconnaissance mission during a simulated missile strike. ARTUµ's primary responsibility was finding enemy launchers while the pilot was on the lookout for threatening aircraft, both sharing the U-2's radar. The flight was part of a precisely constructed scenario which pitted the AI against another dynamic computer algorithm in order to prove the new technology. “We know that in order to fight and win in a future conflict with a peer adversary, we must have a decisive digital advantage,” said Air Force Chief of Staff Gen. Charles Q. Brown, Jr. “AI will play a critical role in achieving that edge, so I'm incredibly proud of what the team accomplished. We must accelerate change and that only happens when our Airmen push the limits of what we thought was possible.” After takeoff, the sensor control was positively handed-off to ARTUµ who then manipulated the sensor, based on insight previously learned from over a half-million computer simulated training iterations. The pilot and AI successfully teamed to share the sensor and achieve the mission objectives. The U-2 Federal Laboratory designed this AI technology to be easily transferable to other systems and plan to further refine the technology. Today's flight provided invaluable data for not only the team to learn from, but also ARTUµ. “Blending expertise of a pilot with capabilities of machine learning, this historic flight directly answers the National Defense Strategy's call to invest in autonomous systems,” said Secretary of the Air Force Barbara Barrett. “Innovations in artificial intelligence will transform both the air and space domains.” The U-2 Federal Laboratory is a 15 U.S.C. compliant organization established to bring together a “confluence of warfighter, developer, and acquirer” vertically-integrated under the same operational roof. The lab has developed and been approved by the National Institute of Standards and Technology to establish the 20th Laboratory Accreditation Program in the federal government. It promotes “edge development” – a concept to develop new software integration on operational systems in a bounded, safe environment. The historic flight with AI comes just two months after the U-2 Federal Laboratory team updated inflight software for the first time during a U-2 training mission. The team leveraged the open-source container-orchestration software Kubernetes, another military first.ieve.
