Title (EN) AIRCRAFT CAPABLE OF HOVERING
(FR) AÉRONEF PERMETTANT UN VOL STATIONNAIRE
Abstract:
(EN) There is disclosed a rotor (3, 3', 3", 3"') for an aircraft (1) capable of hovering, comprising a stationary support structure (10); a rotative element (11), which is rotatable about an axis (A) with respect to stationary support structure (10); at least one blade (13), which is operatively connected with rotative element (11); a source (30) of a magnetic field, which is either stationary or driven in rotation at a first rotational speed (ω1); and an electric conductive element (32), which is operatively connected to rotative element (11) and can be driven in rotation at a second rotational speed (ω2) different from first rotational speed (ω1); electric conductive element (32) is electromagnetically coupled with source (30), so that an electromotive force is magnetically induced in electric conductive element (32) itself, wherein two rings extend radially inward from a tubular body (51) of the rotor hub (12), the first ring (52) connecting to a plurality of thermally conductive rings (90) of a flow deflector (85) at an axial end of the rotor (3, 3', 3", 3"'), the second ring (53) supporting the electric conductive element (32).
(FR) L'invention concerne un rotor (3, 3', 3", 3"') d'un aéronef (1) permettant un vol stationnaire, comprenant une structure de support fixe (10) ; un élément rotatif (11), pouvant tourner autour d'un axe (A) par rapport à la structure de support fixe (10) ; au moins une pale (13) reliée de manière fonctionnelle à l'élément rotatif (11) ; une source (30) de champ magnétique, soit fixe soit entraînée en rotation à une première vitesse de rotation (ω1) ; et un élément électro-conducteur (32) relié de manière fonctionnelle à l'élément rotatif (11) et pouvant être entraîné en rotation à une seconde vitesse de rotation (ω2) différente de la première vitesse de rotation (ω1) ; un élément électro-conducteur (32) couplé de manière électromagnétique à la source (30), de sorte qu'une force électromotrice soit induite par voie magnétique dans l'élément électro-conducteur (32) lui-même, deux anneaux s'étendant radialement vers l'intérieur d'un corps tubulaire (51) du moyeu (12) de rotor, le premier anneau (52) étant en contact avec une pluralité d'anneaux thermo-conducteurs (90) d'un déflecteur de flux (85) au niveau d'une extrémité axiale du rotor (3, 3', 3", 3"'), le second anneau (53) supportant l'élément électro-conducteur (32).
