NºPublicación: EP3192738A1 19/07/2017

Solicitante:
KUZIKOV SERGEJ YUREVICH [RU]

Resumen de: EP3192738A1

The group of inventions relates to aviation and wind energy, and specifically to designs of aircraft rotors and cruise propellers. An "Air Wheel" rotor, having blades with variable pitch and variable torsion, contains a closed wing which is connected to one or a plurality of coaxial bushings by means of torsionally-flexible blades, wherein the connection between the blades and the closed wing may be rigid, elastic or viscoelastic. A movable mounting of blades to the one or plurality of bushings is carried out by means of a torsion element, or by means of an axial hinge or by means of an offset axial hinge. The rotor contains a device for controlling the overall/cyclical pitch of the blades, which are set partially or fully by the relative positions (pan, tilt, shift) of the bushings. The blades may have a complex three-dimensional shape. The profile of the torsionally flexible blades may have a variable concavity. A variable torsional rigidity along a blade and/or a transverse bend allow for a hyperbolic blade rotation which maximally approximates the ideal blade rotation. The "air wheel" rotor has a wide range of applications. Design constraints for increasing flight speed are reduced. The efficiency, strength and durability of variable-pitch propellers are increased, losses and noise are decreased, and vibration is eliminated.
