A vertical takeoff and landing unmanned aerial vehicle (VTOL-UAV) is provided consisting of one central motor which drives one ducted fan and one or more rotors. These rotors can be coaxial with the fan, or can be located off-center being driven via a transmission. For flight control purposes, all or a portion of the air circulated by the ducted fan and/or by the central rotor is diverted through a plurality of side ducts towards the periphery of the vehicle and then downwards, each of these side duct being fitted at their peripheral ends with air-flow vectorization means. These air-flow vectorization means can be in the form of parallel vanes, and/or in the form of thrust-control buckets, which are turnable around axes perpendicular to the flow of air, and are actuated by servomotors via cables or linkages.
Vertical takeoff and landing unmanned aerial vehicle (VTOL-UAV) comprising a central motor which drives one ducted fan, one rotor coaxial with the fan, and a plurality of rotors that are off-centered, said VTOL-UAV being further equipped with a plurality of side ducts which direct all or part of the air moved by the ducted fan outwards, at first up, then horizontally, then downwards, said side ducts being fitted at their peripheral end with air flow vectorization means for the purpose of altitude, attitude and anti-torque control of the VTOL-UAV.
