Dron multirotor cylindrical wing. # This document describes an unmanned air vehicle with four or more drive motors rotating flight (211-214), characterized in that comprises a hollow cylindrical body (11) which acts both as a structural element, to provide aerodynamic lift when the vehicle is moving with its axis close to the horizontal direction. Operations for landing and takeoff, however, the vehicle axle is positioned vertically so that the same drive motors (211-214) provide the necessary upward force, without additional drive elements. The control electronics (31) acts on each drive independently to steer the vehicle in all directions of space. However, at all times, the main feed direction is the axial direction, reducing drag.
