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

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to collapsible unmanned aerial vehicle. Aircraft-type unmanned aerial vehicle with vertical takeoff and landing (VTOL) comprises fuselage; sustainer engine connected to fuselage, onboard equipment attached to fuselage, wing attached to fuselage and containing centre section and console edges attached to it. Beams connected by their central part to centre section and containing in rear part keel, and in front part and in area between wing and stabilizer – electric motors. Stabilizer is attached at the edges to the rear parts of the beams. Wherein centre section comprises spar with wedge-like groove made at its every end and tube made at every end in rear wall area. Each wing console comprises a wedge-shaped tenon protruding from its end in the direction of the centre section, which is a continuation of the wing spar, and a tube made in the area of the rear wall of the wing. Wedge-shaped tenon and cantilever tube are made with possibility of insertion into wedge-shaped slot and into centre-section tube. 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. Group of inventions also relates to a method for assembling such an unmanned aircraft.

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