The invention relates to a flying device with flapping wings, the device comprising a chassis on which two pivots are pivotally mounted about two parallel articulation axes (X), each of the pivots bearing a wing, the device comprising a first oscillation generator in order to oscillate the pivots so as to cause the wings to flap, said first oscillation generator comprising: two arms (6) each secured to one of the pivots (2); two cranks (9) each articulated to the end of one of the arms about axes (X1) which are parallel to the articulation axes (X) of the pivots; a link rod (10) articulated to the ends of the two cranks about axes (X2) which are parallel to the articulation axes (X) of the pivots; means (4) for synchronizing the rotation of the two pivots such that the pivots have equal and opposite rotations; two electric motors (7) arranged so as to each rotate one of the cranks with respect to the associated arm; and control means for controlling and synchronizing the speed of rotation of the motors and for controlling a phase shift between the motors.

L'invention concerne un engin volant à ailes battantes, l'engin comportant un châssis sur lequel deux pivots sont montés à pivotement selon deux axes d'articulation parallèles (X), chacun des pivots portant une aile, l'engin comportant un premier générateur d'oscillations pour provoquer une oscillation des pivots en vue de provoquer un battement des ailes, ledit premier générateur d'oscillations comportant: deux bras (6) solidaires chacun d'un des pivots (2); deux manivelles (9) articulées chacune à l'extrémité d'un des bras selon des axes (X1) parallèles aux axes d'articulation (X) des pivots; une bielle (10) articulée aux extrémités des deux manivelles selon des axes (X2) parallèles aux axes d'articulation (X) des pivots; des moyens de synchronisation (4) de la rotation des deux pivots de sorte que les pivots aient des rotations égales et opposées; deux moteurs électriques (7) disposés pour commander chacun une rotation de l'une des manivelles vis-à- vis du bras associé; des moyens de commande pour commander et synchroniser la vitesse de rotation des moteurs et pour commander un déphasage entre les moteurs.
