À Saclay, la DGA simule l’altitude pour tester les moteurs en conditions extrêmes

L'Usine Nouvelle consacre un article au Centre d'Essais des Propulseurs du Ministère des Armées, situé sur le plateau de Saclay (Essonne), qui dispose de moyens uniques en Europe pour reproduire au sol les conditions de vols extrêmes subies par les aéronefs. Le centre technique utilise l'eau, venue des étangs voisins de Versailles, qui, amenée aux températures et aux pressions voulues, permet de récréer les flux d'air et les conditions atmosphériques de vol dans de grands caissons capables d'accueillir des moteurs. Les cinq caissons atmosphériques du centre permettent de reproduire des conditions de vol extrêmes, que ce soit en termes d'altitude (jusqu'à 20 000 mètres), de vitesse (jusqu'à Mach 3) et de température (de - 70 à + 250 °C). « Par rapport à un vol réel, nous maîtrisons mieux les tests et nous pouvons plus facilement étudier les paramètres qui nous intéressent », explique Marie-José Martinez, la directrice du site. Au-delà des programmes d'armement, le centre propose également des prestations aux grands motoristes mondiaux, tels que Safran ou Rolls-Royce. L'avion de combat SCAF pourrait aussi en bénéficier.

    New military drone roadmap ambivalent on killer robots

    By: Kelsey Atherton Drones are everywhere in the Pentagon today. While unpeopled vehicles are most closely associated with the Air Force and targeted killing campaigns, remotely controlled robots are in every branch of the military and used across all combatant commands. The fiscal year 2018 defense authorization contained the largest budget for drones and robots across the services ever, a sign of just how much of modern warfare involves these machines. Which is perhaps why, when the Department of Defense released its latest roadmap for unmanned systems, the map came in at a punchy 60 pages, far shy of the 160-page tome released in 2013. This is a document less about a military imagining a future of flying robots and more about managing a present that includes them. The normalization of battlefield robots Promised since at least spring 2017, the new roadmap focuses on interoperability, autonomy, network security and human-machine collaboration. The future of drones, and of unpeopled ground vehicles or water vehicles, is as tools that anyone can use, that can do most of what is asked of them on their own, that communicate without giving away the information they are sharing, and that will work to make the humans using the machines function as more-than-human. This is about a normalization of battlefield robots, the same way that mechanized warfare moved from a theoretical approach to the standard style of fighting by nations a few generations ago. Network security isn't as flashy a highlight as “unprecedented battlefield surveillance by flying robot,” but it's part of making sure that those flying cameras don't, say, transmit easily intercepted data over an open channel. “Future warfare will hinge on critical and efficient interactions between war-fighting systems,” states the roadmap. “This interoperable foundation will transmit timely information between information gatherers, decision makers, planners and war fighters.” A network is nothing without its nodes, and the nodes that need to be interoperable here are a vast web of sensors and weapons, distributed among people and machines, that will have to work in concert in order to be worth the networking at all. The very nature of war trends toward pulling apart networks, toward isolation. Those nodes each become a point at which a network can be broken, unless they are redundant or autonomous. Where will the lethal decision lie? Nestled in the section on autonomy, the other signpost feature of the Pentagon's roadmap, is a small chart about the way forward. In that chart is a little box labeled “weaponization,” and in that box it says the near-term goals are DoD strategy assessment and lethal autonomous weapon systems assessment. Lethal autonomous weapon systems are of such international concern that there is a meeting of state dignitaries and humanitarian officials in Geneva happening at the exact moment this roadmap was released. That intergovernmental body is hoping to decide whether or not militaries will develop robots that can kill of their own volition, according to however they've been programmed. The Pentagon, at least in the roadmap, seems content to wait for its own assessment and the verdict of the international community before developing thinking weapons. Hedging on this, the same chart lists “Armed Wingman/Teammate (Human decision to engage)” as the goal for somewhere between 2029 and 2042. “Unmanned systems with integrated AI, acting as a wingman or teammate with lethal armament could perform the vast majority of the actions associated with target identification,tracking, threat prioritization, and post-attack assessment," reads the report. "This level of automation will alleviate the human operator of task-level activities associated with the engagement of a target, allowing the operator to focus on the identified threat and the decision to engage.” The roadmap sketches out a vision of future war that hands off many decisions to autonomous machines, everything from detection to targeting, then loops the lethal decision back to a human responsible for making the call on whether or not the robot should use its weapons on the targets it selected. Humans as battlefield bot-shepards, guiding autonomous machines into combat and signing off on the exact attacks, is a possible future for robots in war, one that likely skirts within the boundaries of still-unsettled international law. Like its predecessor, this drone roadmap is plotting a rough path through newly charted territory. While it leans heavily on the lessons of the present, the roadmap doesn't attempt to answer on its own the biggest questions of what robots will be doing on the battlefields of tomorrow. That is, fundamentally, a political question, and one that much of the American public itself doesn't yet have strong feelings about. https://www.c4isrnet.com/unmanned/2018/08/31/new-military-drone-roadmap-ambivalent-on-killer-robots

    US Air Force looks to up-gun its airlift planes

    By: Valerie Insinna WASHINGTON — Humble airlift planes like the C-130J Super Hercules and C-17 Globemaster III could become heavily-armed weapons trucks capable of airdropping large bundles of munitions that deliver a massive blast. So far, the Air Force has conducted two successful tests of “palletized munitions” from the C-130 and C-17, said Maj. Gen. Clint Hinote, the deputy director of the service's Air Force Warfighting Integration Capability cell. “We are in discussions right now about how do we proceed to prototyping and fielding,” he said during a May 27 event held by the Mitchell Institute for Aerospace Studies. Like the name suggests, palletized munitions are a collection of weapons strapped together onto a smart pallet, which would feed the munitions tracking and targeting information as they are dropped from an airlift platform. A request for information released in February characterized the technology as “a bomb bay in a box” that could allow mobility aircraft to stay out of a threat zone and launch a mass of standoff weapons. “It's all about capacity,” Hinote explained. “You've got to create enough capacity so that a long-range punch is really a punch. What we see is that no matter how big our bomber force is, the capacity that the joint force needs is always more and more. And so this is why we think that there is a real possibility here for using cargo platforms to be able to increase the capacity of fires.” Air Force Special Operations Command conducted one demonstration of the technology on Jan. 28, when a MC-130J performed three airdrops of simulated palletized munitions at at Dugway Proving Ground, Utah. “In this case, munitions stacked upon wooden pallets, or Combat Expendable Platforms (CEPs), deployed via a roller system,” the Air Force Research Laboratory said in a May 27 release. “AFSOC aircrew released five CEPs rigged with six simulated munitions, the same mass as the actual weapons, including four Cargo Launch Expendable Air Vehicles with Extended Range (CLEAVERs) across a spectrum of low and high altitude airdrops." In response to questions from Defense News, AFRL clarified that simulated long-range cruise missiles were deployed from an off-the-shelf pallet system as well as an Air Force designed crate system. CLEAVER is a new weapon under development by the lab as part of a separate effort, though it may be used in palletized munitions in the future. On Feb. 27, Air Mobility Command conducted a similar demonstration with a C-17, which conducted two airdrops of simulated palletized munitions, AFRL said. In future demonstrations, AFSOC plans to release more advanced forms of simulated munitions as well as full-up weapons vehicles that can be configured with a warhead and terminal guidance system. However, the Air Force is looking for other technological options. Through its request for information, which closed in April, the service sought data about new or existing palletized munitions concepts. The service hopes to use that information to inform future experimentation efforts, operational assessments or the acquisition palletized munitions systems. Five companies responded to the RFI, AFRL said. If the effort moves forward, one big question will be figuring out which entities in the Air Force have command over a mobility asset that is playing a combat role more similar to a fighter jet or bomber. “Some kind of extremely streamlined command and control is going to be necessary, or else you must have an integrator somewhere,” said Hinote, who added that cultural barriers inside the Air Force could be harder to overcome than the technological challenges of creating palletized munitions. Hinote also acknowledged that it currently may be hard to find the funding to move forward with a new program. “We're in the last year of an administration. We've had to turn in the budget early with not too many changes, and we're looking at the possibility of a continuing resolution where new starts are going to be difficult to do,” he said. However, “that is all temporary,” he said.
