WING OF AIRCRAFT-TYPE UNMANNED AERIAL VEHICLE WITH VERTICAL TAKEOFF AND LANDING (VTOL) Russian patent published in 2024 - IPC B64U20/50 B64C1/26 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to collapsible unmanned aerial vehicle. Unmanned aerial vehicle wing comprises centre section and cantilevers attached thereto. Centre section comprises spar, ribs attached to spar, rear wall attached to ribs, tube made at each end in area of rear wall, and skin. At that, inside the spar on each end face there is a wedge-shaped slot, and each cantilever contains spar, ribs attached to the spar, rear wall attached to the ribs, and the skin, as well as a wedge-shaped tenon protruding from the end of the cantilever in the direction of the centre section , which is a continuation of the cantilever spar, and a tube made in the area of the rear wall of the cantilever. Wedge-shaped tenon and cantilever tube are made with possibility of insertion into wedge-shaped slot and into centre-section tube. At that, inner size of wedge-shaped slot and tube in centre section corresponds to outer size of mating wedge-shaped tenon and tube protruding from wing cantilever. Value of narrowing of the wedge-shaped tenon from the end of the cantilever in the external direction and of the wedge-like slot from the end of the centre section in the internal direction is equal to the narrowing of the tool Morse cone.

EFFECT: simplification and acceleration of assembly/disassembly and transportation of UAV, as well as increase in reliability and safety of collapsible UAV.
