  • Patent number: 11518509
    Abstract: A tethered aerial vehicle, connected to an anchorage system in the ground level through a cord, comprising a pair of fixed wings; and a drive assembly. The drive assembly comprises at least two actuators configured to tilt the axle of the propellers. The fixed wings define a center hole located close to a gravitational center of the aerial vehicle. Within the edges of the center hole located close to the gravitational center of the aerial vehicle is a gimbal anchored to the fixed wings' structure. The drive assembly is located within the edges of the center hole and attached to the gimbal in a manner that the gimbal interfaces the connection between the fixed wings and the drive assembly. The drive assembly comprises of at least two propellers mounted on the same axle (“coaxial propellers”) driven by a counter-rotating motor. The coaxial propellers are configured to rotate in opposite directions with respect to each other.
