UCAR [for] Unmanned Combat Armed Rotorcraft ... will be an all-weather, highly autonomous and survivable unmanned rotorcraft fully integrated into the Army's objective force combat maneuver force structure. The system, which enables ground maneuver force superiority, will be capable of collaborating with multiple UCARs and other manned and unmanned systems. Unlike other unmanned aerial vehicles, however, the UCAR will not have a dedicated ground station. Instead, the system will integrate into existing command and control platforms, such as the Future Combat Systems command and control vehicle and combat aviation. Capable of autonomous mission planning while in flight, the UCAR will request guidance from a human operator only for tasking and final weapons authorization. 3, record 1, English, - unmanned%20combat%20armed%20rotocraft

Dans le cadre du programme Ucar, Boeing a breveté un nouveau concept de drône hélicoptère de combat [...], furtif et modulaire [...] Les ingénieurs de Boeing proposent d'intégrer la turbine dans le plan vertical. [...] Positionner la turbine dans l'axe même du rotor, où se trouve le centre de masse du véhicule, revient, en effet, à limiter sa capacité d'emport tant en masse qu'en volume. Les inventeurs proposent ici de redistribuer la charge utile dans trois bras carénés et détachables, disposés en étoile autour d'une structure porteuse centrale. Pour contrôler le couple principal, contrôler l'attitude et manœuvrer l'engin, un sous-système hybride a été privilégié. Il se compose d'une soufflante contra-rotative coaxiale au rotor principal, carénée dans la structure centrale, et de petits réacteurs à jets d'air comprimé, régulés par des «valves» et installés aux bouts de chaque bras. L'air comprimé au niveau de la turbine, est conduit à destination par simple tuyauterie. Quant à la soufflante anti-couple, elle participe au circuit de refroidissement en ventilant la structure centrale qu'échauffe la turbine. 1, record 1, French, - drone%20h%C3%A9licopt%C3%A8re%20de%20combat
