Moreover, the fluid flow energy collected through the wings 54 generates power through a single location, for instance at the wheel 65. It is however considered to separate the two DOFs of the oscillating-wing mechanism 50 so as to control each separately.

Abstract

L'invention concerne un mécanisme à ailes oscillantes comprenant deux ailes oscillantes. Un sous-mécanisme de levage comprend un bras relié de manière pivotante au niveau de la partie centrale à une base et deux ailes oscillantes qui sont reliées aux extrémités opposées du bras par des joints rotatifs. Le sous-mécanisme de levage présente des éléments de contrainte placés entre la base et le bras de manière à entraîner le bras dans un mouvement oscillant, les ailes oscillantes se déplaçant avec un degré de liberté de levage. Un sous-mécanisme d'inclinaison est relié entre les joints rotatifs et la base de manière à entraîner les ailes oscillantes dans un degré de liberté d'inclinaison. Des actionneurs sont placés sur la base et reliés au sous-mécanisme de levage et au sous-mécanisme d'inclinaison afin de commander les degrés de liberté d'inclinaison et de levage. Le mécanisme à ailes oscillantes est utilisé pour extraire de la puissance à partir d'un flux de fluide ou pour produire des forces de propulsion.
