ROTARY MACHINE COMPRISING A ROTOR PLACED IN A FLUID AND EQUIPPED WITH ORIENTABLE BLADES

摘要

A fluidic rotor rotary machine has a rotor comprising at least one blade (4) mounted on an arm (2) rotating about a main axis (1) of the rotor, the rotor being held by a support structure (5) in an orientation such that said axis (1) is essentially perpendicular to the fluid flow direction, the blade (4) being pivotally mounted about a rotational axis (3) parallel to the main axis (1), the machine being characterized in that it comprises means for generating a relative rotational movement of the blade (4) relative to the arm (2) at the rotational axis (3), thereby varying the blade angle, said means comprising an eccentric mechanism rotating on said blade rotational axis. Application in particular to propellers and generators operating according to Lipp-type or Voith-Schneider-type kinematics, with possible mode switching.
