Patent ID: 8333342

Claim:
A flapping-wing flying vehicle, the vehicle including a frame having two pivots mounted thereon to pivot about two parallel hinge axes (X), each pivot carrying a respective wing, the vehicle including a first oscillation generator for causing the pivots to oscillate in order to cause the wings to flap, wherein said first oscillation generator comprises: two arms ( 6 ), each secured to a respective pivot ( 2 ); two cranks ( 9 ), each hinged to the end of a respective one of the arms about respective axes (X 1 ) parallel to the hinge axes (X) of the pivots; a connecting rod ( 10 ) hinged to the ends of the two cranks about axes (X 2 ) parallel to the hinge axes (X) of the pivots; synchronization means ( 4 ) for synchronizing the rotation of the two pivots such that the rotations of the pivots are equal and opposite; two electric motors ( 7 ), each placed to cause one of the cranks to rotate relative to the associated arm; and control means ( 50 ) for controlling and synchronizing the speeds of rotation of the motors and for controlling the phase difference between the motors.
