Title (EN) MAIN ROTOR ARRANGEMENT OF AN UAV-HELICOPTER
(FR) AGENCEMENT DE ROTOR PRINCIPAL D'UN HÉLICOPTÈRE SANS PILOTE
Abstract: front page image
(EN)The present invention relates to a main rotor arrangement (1) for an UAV-helicopter, comprising a rotor mast (3) defining a vertical axis of rotation (R), and a hub (5) for attachment of rotor blades, wherein the hub (5) is mounted to the rotor mast (3) in a tiltable way so as to reduce loads acting on the rotor blades during operation of the UAV-helicopter. The main rotor arrangement (1) comprises a damping assembly (18) for damping said tilting of the hub (5).
(FR)La présente invention concerne un agencement de rotor principal (1), destiné à un hélicoptère sans pilote, qui comprend un mât rotor (3) définissant un axe de rotation (R) vertical et un moyeu (5) conçu pour fixer les pales du rotor. Le moyeu (5) est monté de manière inclinée sur le mât rotor (3) pour réduire les charges sur les pales du rotor lorsque l'hélicoptère sans pilote est en marche. L'agencement de rotor principal (1) comprend un ensemble d'amortissement (18) conçu pour amortir ladite inclinaison du moyeu (5).
