Title:
PROPULSION DEVICE FOR A ROTARY WING AERODYNE WITH VERTICAL TAKE-OFF AND LANDING, AND AERODYNE EQUIPPED WITH SUCH A PROPULSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/148595
Kind Code:
A1
Abstract:
The invention relates to a device (1) for propelling, by means of counterrotating coaxial propellers, a rotary wing aerodyne with vertical take-off and landing. This device comprises a hollow chassis (5) and two propellers each having a blade-carrying ring (6) which carries the blades at a fixed pitch. Drive means (14) make it possible to rotate each propeller about its axis of rotation, and inclination control means (24) make it possible to incline said propellers about the roll axis and the pitch axis, and comprise two pairs of control rods (26) which can be translated in parallel with the yaw axis in both directions by two control devices (27) such that one end of each rod (26) is able to bear against a blade-carrying ring (6) so as to tilt said ring about the roll axis or the pitch axis.
