Researchers from the U.S. Army Research Laboratory and Bell Helicopter met in June 2018 to focus on the development of micro unmanned aerial systems (UAS). The project surrounds what Bell describes as miniature, lightweight reconnaissance vehicles that soldiers can carry onto the battlefield and deploy in a confined space.
The collaboration began after Bell representatives travelled to Adelphi, Maryland, to attend an open campus event at the U.S. Army Research Laboratory (ARL) in November 2016. After a year and a half of information sharing, the two parties signed a five-year cooperative research and development agreement (CRADA) in March 2018.
“We're trying to get data on the fundamental level, to build up a knowledge base of vehicles, because their expertise is in designing the vehicles, whereas our expertise is the fundamentals of them,” said Dr. John Hrynuk, a mechanical engineer in ARL's Vehicle Technology Directorate (VTD). “We want new technology; they want new vehicles. Together, we want to enhance technologies for the soldiers – that's what makes it the absolute perfect collaboration.”
Bell engineers Dakota Easley and Levi Hefner recently visited ARL to perform experiments on micro UAS using the facility's wind tunnel. Bell explains the visit was prompted by vehicle control challenges its researchers had observed in early flight testing. With the help of ARL scientists and equipment, according to Bell, the engineers were able to isolate their earlier challenges and improve the performance of the aerial vehicle.
“The wind tunnel here at ARL has been beneficial in providing data that explains why certain things are happening on the control side. Now we're able to better analyze our tests to enhance the performance of our vehicles,” Hefner said. “This collaboration is great because we're heading into a new design space with these small vehicles.”

L'OTAN a sélectionné l'offre Nexium Defence Cloud de Thales afin de déployer le cloud de ses futurs centres de commandement modulaires. La technologie de Thales doit offrir une interopérabilité et une communication ultra-sécurisée entre le centre de commandement et les thé'tres d'opérations, et accélérer la transformation numérique des forces armées coalisées. Déployable en moins de 24 heures, la solution Nexium Defence Cloud permet à l'OTAN de réduire le nombre de ses ingénieurs informatiques sur sites, gr'ce à son système d'orchestration, en réduisant les déploiements des services informatiques et applicatifs de sites distants de plusieurs milliers de kilomètres à quelques heures, avec un nombre d'experts limité. « Basée sur une approche globale incluant à la fois la gestion des applications, l'IT (Information Technology), les réseaux et la sécurité, cette solution repose également sur une architecture adaptée pour divers niveaux de confidentialité », précise Thales. « Cette solution, la plus compacte, intégrée et modulaire du marché, inclut tous les constituants des postes de commandements militaires (caissons, serveurs, stockage de données, système de supervision...), répondant au niveau de performance exigé en termes de volume, taille, poids et consommation énergétique, simplifiant la logistique de déploiement », explique le groupe.
