An unmanned aerial vehicle includes a propulsion system having at least one propulsion module comprised of at least one propeller and at least two motors/engines, one or more of the motors/engines providing mechanical energy to drive the propeller, wherein the difference between the angular velocities of the motors/engines provides energy input to a mechanical or magneto-mechanical linkage system to change the blade pitch angle of the propeller, in cyclic and/or collective manner.

    L'invention concerne un véhicule aérien sans pilote comprenant un système de propulsion ayant au moins un module de propulsion constitué d'au moins une hélice et d'au moins deux moteurs, un ou plusieurs moteurs fournissant de l'énergie mécanique pour entraîner l'hélice, la différence entre les vitesses angulaires des moteurs fournissant une entrée d'énergie à un système de liaison mécanique ou magnéto-mécanique pour modifier l'angle de pas de pale de l'hélice, cycliquement ou collectivement.
