Title
(EN) AERODYNAMICALLY EFFICIENT LIGHTWEIGHT VERTICAL TAKE-OFF AND LANDING AIRCRAFT WITH PIVOTING ROTORS AND STOWING ROTOR BLADES

Abstract
(EN) An aerial vehicle adapted for vertical takeoff and landing using a set of wing mounted thrust producing elements and a set of tail mounted rotors for takeoff and landing. An aerial vehicle which is adapted to vertical takeoff with the rotors in a rotated, take-off attitude then transitions to a horizontal flight path, with the rotors rotated to a typical horizontal configuration. The aerial vehicle uses different configurations of its wing mounted rotors and propellers to reduce drag in all flight modes.
(FR) La présente invention concerne un véhicule aérien pouvant effectuer un décollage et un atterrissage verticaux au moyen d'un ensemble d'éléments produisant une poussée montés sur les ailes et d'un ensemble de rotors montés en queue pour le décollage et l'atterrissage. L'invention porte sur un véhicule aérien qui est conçu pour effectuer un décollage vertical avec les rotors en rotation dans une attitude de décollage et pour passer ensuite à une trajectoire de vol horizontale, avec les rotors qui tournent dans une configuration horizontale typique. Le véhicule aérien utilise différentes configurations de ses rotors montés sur les ailes et de ses hélices pour réduire la traînée dans tous les modes de vol.
