Title (EN) CONVERTIBLE LIFTING PROPELLER FOR UNMANNED AERIAL VEHICLE
(FR) HÉLICE DE LEVAGE CONVERTIBLE POUR VÉHICULE AÉRIEN SANS PILOTE
Abstract:
(EN) Described is a configuration of an unmanned aerial vehicle ("UAV") that includes one or more lifting propellers that may be converted between an operational configuration and a transit configuration. When the lifting propeller is in a operational configuration, the leading edge of each propeller blade is aligned in the direction of rotation so that the lifting propeller will generate a positive lifting force when rotated by a lifting motor. When the lifting propeller is in the transit configuration, the leading edge of each of the propeller blades are oriented toward a direction of a transit flight of the aerial vehicle. Likewise, the lifting propeller is maintained in a fixed position during the transit flight so that airflow passing over the propeller blades of the lifting propeller cause vertical lift.
(FR) La présente invention concerne une configuration d'un véhicule aérien sans pilote (UAV) comprenant une ou plusieurs hélices de levage qui peuvent passer d'une configuration opérationnelle à une configuration de transit. Lorsque l'hélice de levage est dans une configuration opérationnelle, le bord d'attaque de chaque pale d'hélice est aligné dans le sens de rotation de telle sorte que l'hélice de levage génère une force de levage positive lorsqu'elle est mise en rotation par un moteur de levage. Lorsque l'hélice de levage est dans la configuration de transit, le bord d'attaque de chacune des pales d'hélice est orienté vers une direction d'un vol de transit du véhicule aérien. De même, l'hélice de levage est maintenue dans une position fixe pendant le vol de transit de telle sorte que le flux d'air passant au-dessus des pales d'hélice de l'hélice de levage entraîne une ascension verticale.
