Patent attributes
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.
