Abstract

L'invention est un concept de drone à voilure hybride, composé à la fois d'actionneurs rotatifs (hélices) pivotants et d'ailes déployables. L'invention reprend une partie du brevet US14/626,357 qui couvre la possibilité d'utiliser un même moteur pour assurer la sustentation et la propulsion d'un véhicule. L'invention va cependant au-delà du périmètre de ce brevet, en n'utilisant que des actionneurs rotatifs montés sur pivots dans la configuration du véhicule pour l'ensemble de ses asservissements de vol, ainsi qu'en adjoignant des ailes déployables à l'ensemble et un système de repose au sol rétractable. L'invention est de fait optimisée par ces modifications par rapport aux drones existants, notamment en améliorant fortement la dynamique de vol et les capacités opérationnelles, en particulier de déploiement rapide.
