La Direction générale de l'armement a inauguré le 19 décembre 2019 sur son centre d'expertise et d'essais Techniques aéronautiques à Balma (proche de Toulouse) un cluster d'innovation technique de défense dans le domaine de l'aéromobilité. Baptisé CI-AILE, ce cluster a été créé en associant quatre partenaires régionaux fondateurs : la DGA, l'armée de Terre, l'institut supérieur de l'aéronautique et de l'espace (ISAE-SUPAERO) et la communauté défense du pôle Aerospace Valley dans les régions Occitanie et Nouvelle Aquitaine. Le cluster CI-AILE a pour objectif de détecter, orienter et expérimenter les innovations portées par les acteurs régionaux afin de faire émerger de nouvelles solutions technologiques pour la défense dans le domaine de l'aéromobilité en lien avec l'Agence de l'innovation de défense (AID). Basé en région Occitanie, il pourra bénéficier d'un écosystème riche dans le domaine aéronautique et en particulier dans celui de l'aéromobilité, tout en restant ouvert à des partenariats avec des acteurs implantés dans d'autres régions de France. Le comité stratégique de CI-AILE est co-présidé par le directeur du centre d'expertise et d'essais DGA Techniques aéronautiques, le sous-chef d'état-major plans et programmes de l'armée de Terre, le directeur général de l'institut supérieur de l'aéronautique et de l'espace . Son comité de pilotage comprend un représentant de chaque membre fondateur. Ce nouveau cluster s'inscrit dans l'effort global du ministère des Armées en faveur du soutien à l'innovation, coordonné par l'Agence de l'innovation de défense en lien étroit avec la DGA. CI-AILE est un partenariat dont le fonctionnement repose sur un comité stratégique qui donne les orientations du cluster et un comité de pilotage qui anime et conduit les ateliers technico-opérationnels. Le comité de pilotage de ce cluster est constitué de personnels de DGA Techniques aéronautiques, de la 11e brigade parachutiste basée à Toulouse, du commandement des forces spéciales terre basé à Pau, de l'ISAE-SUPAERO et d'Aerospace Valley. Il se réunira pour la première fois en janvier 2020. Les périmètres attendus de l'innovation dans le domaine de l'aéromobilité sont la captation et l'évaluation de technologies innovantes dans les domaines : - du parachutage de combattants de l'armée de Terre et d'équipements, de mise à terre à partir d'aéronefs (aérolargage, aérocordage...) - de l'embarquement sur aéronefs (voilure fixe et tournante) de combattants de l'armée de Terre et d'équipements (aérotransport, aérocordage...) - de l'équipement du combattant débarqué et embarqué, toutes fonctions opérationnelles confondues, et de son adaptation aux contraintes du parachutiste - des méthodes et des moyens d'essais et de la R&T dans le domaine de l'aéromobilité. Cinq clusters d'innovation techniques ont déjà été créés en 2019 par la DGA autour de ses centres d'expertise et d'essais, CI-AILE étant le sixième : ALIENOR à Saint-Médard-en-Jalles dans le domaine aérospatial GIMNOTE à Toulon et ORION à Brest pour le domaine des techniques navales GINCO à Vert-le-Petit (Essonne) dans le domaine de la maitrise des techniques nucléaire, radiologique, biologique et chimique LAHITOLLE à Bourges dans le domaine des techniques terrestres. https://www.defense.gouv.fr/dga/actualite/la-dga-lance-ci-aile-un-cluster-d-innovation-technique-de-defense-dans-le-domaine-de-l-aeromobilite

By: Todd South As Army leadership looks to transform ground operations and logistics experts shave supply requirements such as fuel, work being done to generate more electric power with less fuel is at the heart of the land fight in the next wave of warfare. The two paths converge at work being done to “electrify” the future vehicle fleet at the Army's center for vehicle research – the Tank Automotive Research Development and Engineering Center. A November forum at TARDEC focused on advances in vehicle electrical power as service leaders, industry experts and researchers pursue ways to give more soldiers more power to run complex systems of the future. The first such forum took place in June and laid out an overview of what will need to happen to reach Army goals. Over the next year, participants will refine their plans to build a complex fleet of vehicles capable of a host of tasks not yet fielded. Vehicles have come a long way from moving forward and backward and carrying troops and ammo. “The electrical demands on the Army's vehicles today are growing far beyond anything we've seen before,” said George Hamilton, TARDEC's lead for Vehicle Electronics Architecture. “Our focus is on developing and providing a modular, flexible and adaptable vehicle architecture that can expand to meet future demands of all kinds.” And the goals are ambitious. The Army wants most of the electrification infrastructure in place or ready for testing by mid-2024 and a working, all-electric power train for the fleet by 2027. The systems and capabilities that the electrification project is pursuing are aimed at enabling seamless Multi-Domain Operations in which forces can access limited windows in the fight at various domains, from the traditional air-land-sea to cyber-electronic warfare-space domains. But, power demands on legacy vehicles only grow as more systems are added, experts said. Over time, that's meant entirely new wiring, amplifiers and other electronics architecture for the same vehicles that have been in service for decades. For example, in 2001, the standard vehicle only required a 150 amp alternator to power its onboard systems. Today, that same vehicle needs 10 times the amperage to run all of the weapon systems, computers, radios, monitors and cameras on current vehicles. At a recent talk at the Association of the U.S. Army, Lt. Gen. Aundre Piggee, the Army G-4, said that future combat operations will not be able to rely on forward operating bases. Logisticians will need to find expeditionary ways to move supplies, especially fuel, to combat units. Current brigade combat teams are able to operate for about three days before a full resupply. But Piggee said that the goal is to stretch that to seven days. To meet that end, a variety of options are being explored, but the main supply saver is reducing demand, specifically fuel. BCTs will need to use at least one-third less fuel to keep their standalone abilities at the one-week mark, he said. That extends beyond petroleum and to battery life, power consumption on smart grids, and anywhere else that technology procedures and advancements can make the formation lethal as long with less fuel or power consumption. So, at the same time that larger formations must be more self-sustaining and use less fuel, the systems that enable their fighting might will need more power. Tomorrow's vehicles will need to do much more than what's being demanded now. On the Army wish list are energy weapon systems to counter rockets, missiles and drones, wireless energy beaming to help with running unmanned ground vehicles and aerial drones with remote power, non-lethal energy weapons for crowd disbursement, silent modes for vehicle movement, high-power electronic jamming, electronic armor to deflect electromagnetic spectrum and projectile attacks, and long-range electromagnetic guns for multiple uses. And the backbone of those capabilities is an open architecture powering system on the next wave of ground vehicles that nearly any system built today or decades from now can plug into, and it will provide the power needed to run. Part of that, the Next-Generation Combat Vehicle Electrical Power Architecture, has been in development at TARDEC since 2012. Once implemented, the system is expected to provide fuel efficiency that will reduce fuel consumption by more than 10 percent and provide 20 percent more efficient power generation and energy transfer. That will put less strain on the vehicle systems while using less fuel and providing more power. And, it can take powerful hybrid vehicles, those using both petroleum-based fuels and battery or fuel cell power. This effort is coupled with a recent partnership between TARDEC and the U.S. Department of Energy into hydrogen fuel cell technology. “We think hydrogen as a fuel source, and the fuel cells that generate electricity from the hydrogen, will enable enormous capability for our warfighters,” Paul Rogers, director of TARDEC, said in a release. The applications go beyond fuel efficiency and reducing fuel logistics burdens. “Vehicles using hydrogen run on electric motor propulsion, giving very low noise and thermal signatures while in operation,” Rogers said. “Additionally, we can generate valuable electrical power using hydrogen fuel cells that currently requires noisy and heavy generators.” Both of those efforts could help not only operational forces in the tactical fight but the surrounding support that brings them their supplies. https://www.armytimes.com/news/your-army/2018/11/08/from-crowd-control-to-wireless-energy-beaming-the-armys-new-vehicles-must-have-more-power-but-use-less-fuel
