Title (EN) PROPULSION SYSTEM COMPRISING SEPARABLE PROPELLER AND UNMANNED AERIAL VEHICLE COMPRISING SAME
(FR) SYSTÈME DE PROPULSION COMPRENANT UNE HÉLICE SÉPARABLE ET VÉHICULE AÉRIEN SANS PILOTE LE COMPRENANT
(KO) 분리형 프로펠러를 포함한 추진 시스템 및 이를 포함하는 무인 비행체
Abstract:
(EN) An unmanned aerial vehicle according to various embodiments of the present disclosure comprises: a housing; a wireless communication circuit connected to the housing or positioned in the housing and configured to connect wireless communication with an external controller; a plurality of propulsion systems connected to the housing or at least partially contained in the housing; and a navigation circuit configured to control the plurality of propulsion systems. At least one of the plurality of propulsion systems comprise a motor controlled by the navigation circuit and a propeller assembly connected to the motor. The propeller assembly may comprise: a first structure which is fixed to the motor, which has a cylindrical wall defining an inner space, and which comprises a helical slit formed through the cylindrical wall; a second structure comprising a cylinder portion, at least a part of which is rotatably positioned in the inner space, and at least one protruding portion that protrudes from the outer surface of the cylinder portion to the outside of the cylindrical wall through the helical slit; and a propeller comprising a cylindrical hub engaging with the cylinder portion of the first structure, a plurality of rotating blades extending from the cylindrical hub, and at least one rib extending from the cylindrical hub toward the motor, the propeller being configured such that at least a part of the rib detachably engages with the first structure by the at least one protruding portion of the second structure. Other embodiments are also possible.
(FR) L'invention concerne un véhicule aérien sans pilote qui, selon divers modes de réalisation, comprend : un boîtier ; un circuit de communication sans fil connecté au boîtier ou positionné dans le boîtier et conçu pour permettre une communication sans fil avec un dispositif de commande externe ; une pluralité de systèmes de propulsion reliés au boîtier ou au moins partiellement contenus dans le boîtier ; et un circuit de navigation conçu pour commander la pluralité de systèmes de propulsion. Au moins l'un de la pluralité de systèmes de propulsion comprend un moteur commandé par le circuit de navigation et un ensemble hélice relié au moteur. L'ensemble hélice peut comprendre : une première structure qui est fixée au moteur, qui a une paroi cylindrique définissant un espace interne, et qui comprend une fente hélicoïdale formée à travers la paroi cylindrique ; une seconde structure comprenant une partie cylindre, au moins une partie de celle-ci étant positionnée de manière rotative dans l'espace interne et au moins une partie en saillie qui fait saillie à partir de la surface externe de la partie cylindre vers l'extérieur de la paroi cylindrique à travers la fente hélicoïdale ; et une hélice comprenant un moyeu cylindrique en prise avec la partie cylindre de la première structure, une pluralité de pales rotatives s'étendant à partir du moyeu cylindrique et au moins une nervure s'étendant depuis le moyeu cylindrique vers le moteur, l'hélice étant conçue de telle sorte qu'au moins une partie de la nervure vienne en prise de manière détachable avec la première structure par la ou les parties en saillie de la seconde structure. D'autres modes de réalisation sont également possibles.
