The invention discloses a tilting duct vertical take-off and landing unmanned aerial vehicle which comprises a fuselage, wings, an empennage and a duct propeller assembly, a tilting mechanism is further arranged in a fuselage main body and comprises a tilting rod, and the duct propeller assembly comprises a lift force duct propeller, a tilting duct and a tilting duct propeller. The lift force ducted propellers comprise two pairs of coaxial reverse propellers, the tilting ducts are arranged on the left side and the right side of the fuselage, the tilting ducts on the left side and the right side are in tilting transition in a synchronous tilting mode, the tilting rods are fixedly connected with the tilting ducted propellers, and the tail duct is arranged on the rear middle section of the axis of the fuselage. A double-cross-shaped supporting frame is supported and embedded in the inner wall of the tail duct, a transmission system is arranged on the double-cross-shaped supporting frame, and the transmission system is connected with the lift force duct propellers. The structural mode that the tilting ducts and the tilting duct propellers are externally connected and the lift force duct propellers are arranged in the fuselage is adopted, so that the unmanned aerial vehicle is low in noise and high in safety; and the aerodynamic efficiency is improved.
