Title (EN) ROTOR FLIGHT VEHICLE
(FR) VÉHICULE DE VOL À ROTOR
Abstract:
(EN) . Rotor flight vehicle (1) comprising a first rotor (2), a power unit (3), a transmission (50) from the power unit (3) to the first rotor (2), wherein said transmission(50) comprises at least one belt (4), a group of rotational axes (Y-Y, X-X), at least one power output axle (5) connected to the power unit (3) and at least one rotor axle (10) connected to said first rotor (2), the belt (4) being an endless belt having alength and a width, the belt (4) is applied to the power output axle (5), the power output axle (5) is concentric with a rotational axis (X-X), the belt (4) transmits power to the rotor axle (10), the rotor axle (10) is concentric with a rotational axis (Y-Y), wherein consecutive rotational axes of the group of rotational axes extend in a relation to each other such that the angle between them is in the range of 80-100 degrees, preferably essentially 90 degrees, wherein the belt (4) as applied in the transmission (50) has a maximal torsion of 80 -100 degrees, preferably essentially 90 degrees, in the belt's (4) transition between two respective consecutive rotational axes of the group of rotational axes.
(FR) La présente invention porte sur un véhicule de vol à rotor (1) comprenant un premier rotor (2), une unité de puissance (3), une transmission (50) de l'unité de puissance (3) au premier rotor (2), ladite transmission (50) comprenant au moins une courroie (4), un groupe d'axes de rotation (Y-Y, X-X), au moins un axe de sortie de puissance (5) relié à l'unité de puissance (3) et au moins un axe de rotor (10) relié audit premier rotor (2), la courroie (4) étant une courroie sans fin ayant une longueur et une largeur, la courroie (4) étant appliquée à l'essieu de sortie de puissance (5), l'axe de sortie de puissance (5) étant concentrique avec un axe de rotation (X-X), la courroie (4) transmet de l'énergie à l'axe de rotor (10), l'axe de rotor (10) est concentrique avec un axe de rotation (Y-Y), des axes de rotation consécutifs du groupe d'axes de rotation s'étendant dans une relation l'un par rapport à l'autre de telle sorte que l'angle entre eux se situe dans la plage de 80 à 100 degrés, de préférence sensiblement 90 degrés, la courroie (4) telle qu'appliquée dans la transmission (50) présente une torsion maximale de 80-100 degrés, de préférence essentiellement de 90 degrés, dans la transition de la courroie (4) entre deux axes de rotation consécutifs respectifs du groupe d'axes de rotation.
