NEW CONVERTIBLE VERTICAL TAKE-OFF AND LANDING UNMANNED AERIAL VEHICLES (VTOL UAVS)

A new VTOL UAV with an associated feedback control approach have been designed. The vehicle consists of coplanar propellers and a wing that can rotate around an axis belonging to the propellers’ plane. An efficient control of the vehicle can be obtained without air-velocity measurements. Finally, the structure is easily scalable: wings can be replaced by different wings, without impacting on the rest of the structure, knowing that various wings will be more or less good adapted according to the conditions of flight, speeds of flight and the embarked payload.
