  ROBOpilot makes maiden flight in US Air Force tests

  By David Szondy A new US Air Force kit that can turn a conventional aircraft into a robotic one has completed its maiden flight. Developed by the Air Force Research Laboratory (AFRL) and DZYNE Technologies Incorporated as part of the Robotic Pilot Unmanned Conversion Program, the ROBOpilot made its first two-hour flight on August 9 at the Dugway Proving Ground in Utah after being installed in a 1968 Cessna 206 small aircraft. With modern autopilots, even small modern aircraft already have surprising ability to fly themselves, but there's a big difference between maintaining a course and actually flying an aircraft the way a human pilot does. From the opposite direction, autonomous drones are becoming increasingly sophisticated, but these tend to be highly specialized and expensive. Funded by AFRL's CRI Small Business Innovative Research project, ROBOpilot is designed to make these two paths meet in the middle by replacing the pilot seat (and pilot) with a kit consisting of all the actuators, electronics, cameras, and power systems needed to fly a conventional aircraft, plus a robotic arm for the manual tasks. In this way, ROBOpliot can operate the yoke, rudder, brakes, throttle, and switches while reading the dashboard gauges and displays like a human pilot. According to the Air Force, the installation is simple, non-invasive and non-permanent, using standard commercial technologies and components. This allows planes to be converted to unmanned operations without the complexity and costs of purpose-built UAVs, and switched back to human control configuration when required. The recent flight comes after a year of building and testing that involved trialing the device concept using a RedBird FMX simulator to demonstrate how well it can fly in a simulated environment before progressing to the real thing. The US Federal Aviation Administration-certified trainer showed that ROBOpilot could carry out autonomous takeoffs, mission navigation, and landings in both normal and abnormal conditions. "Imagine being able to rapidly and affordably convert a general aviation aircraft, like a Cessna or Piper, into an unmanned aerial vehicle, having it fly a mission autonomously, and then returning it back to its original manned configuration," says Dr. Alok Das, Senior Scientist with AFRL's Center for Rapid Innovation. "All of this is achieved without making permanent modifications to the aircraft." https://newatlas.com/us-air-force-robopilot-flight/61105/

  Quand Emmanuel Macron joue au petit alchimiste avec les milliards du Fonds défense

  (B2) La présidence de la république française s'est livrée à un petit bilan du discours de la Sorbonne prononcé en septembre dernier. Bilan somme toute intéressant et normal... s'il ne comportait pas de grossières erreurs, voire des tentatives de manipulations de faits Dans le « point d'étape de l'initiative de la Sorbonne », diffusé ce mardi (5 mars) sur le site de l'Elysée, on retrouve sous l'intitulé : budget de défense commun... ceci : Ceux qui connaissent le sujet, comme B2 le suit depuis des années, ont eu une étrangre sensation : aurais-je perdu une étape, oublié un chiffre quelque part...

  US Air Force may have accidentally revealed interest in hypersonic nuke

  By: Valerie Insinna WASHINGTON — The U.S. Air Force has issued, and quietly revoked, a solicitation to industry seeking technologies that would support a hypersonic glide vehicle capable of traversing intercontinental ranges, potentially signaling the military's interest in a hypersonic nuclear weapon. According to an Aug. 12 request for information first reported by Aviation Week, the Air Force Nuclear Weapons Center sought ideas for potential upgrades to intercontinental ballistic missiles, including a “thermal protection system that can support [a] hypersonic glide to ICBM ranges.” The items listed as potential ICBM upgrades were all marked “unclassified/for official use only,” which notes information that — while not secret — is not normally released to the public. The RFI was then withdrawn after Aviation Week began inquiring about it, the report noted. Asked about the RFI on Wednesday, Lt. Gen. Richard Clark, the Air Force's deputy chief of staff for strategic deterrence and nuclear integration, said the service's next-generation ICBMs — known as the Ground Based Strategic Deterrent — will not be available as a hypersonic variant when it is fielded in the late 2020s. “With a weapon system that's going to be fielded until the 2070 time frame, it's hard to know exactly where we may go with that down the road,” he during an event hosted by the Mitchell Institute for Aerospace Studies. “Right now, though, the threshold warhead does not include hypersonic glide vehicles. I think I can say that safely without talking too much about what the warheads will look like.” However, he noted that GBSD's open-architecture backbone makes it able to adopt emerging technologies. He did not comment specifically on whether a hypersonic glide vehicle was under consideration. As we bring the system online, we will ensure that we have the ability to roll different technologies in and to incorporate that into GBSD,” he said. “And that's one of the, I think, best features ... of GBSD, is that it's going to give us that flexibility. So that if we decide down the road that there's a particular technology that needs to be incorporated, we'll be able to do that.” As the sole bidder in the GBSD competition, Northrop Grumman is expected to win an estimated $85 billion over the life of the program. A contract award is slated to occur by September, although Northrop CEO Kathy Warden said in April that she expected a decision this month. https://www.defensenews.com/smr/nuclear-arsenal/2020/08/19/the-air-force-might-be-eyeing-a-hypersonic-nuclear-weapon/
