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

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to design of a collapsible unmanned aerial vehicle. Unmanned aerial vehicle wing centre section comprises spar made in the form of a longitudinal box-type structural element comprising an inner wall and outer walls made of composite materials, wherein the thickness of the outer walls is less than the thickness of the inner wall of the spar; ribs attached to the spar and having the shape of the wing aerofoil; a rear wall attached to the ribs and made in the form of a longitudinal box-type element of composite materials; a skin attached to the spar, ribs and rear wall and comprising three layers, wherein the inner layer is made from thin foam plastic and the outer layers are made from composite materials; and at each end a first docking assembly made inside the spar in the space between the outer walls and having the shape of a wedge-shaped slot, which tapers from the end rib in the inner direction, wherein the taper value is equal to the taper of the Morse tool taper, wherein the wedge-shaped groove is intended to receive a mating wedge-shaped tenon protruding from the wing console; and at each end a second docking assembly, made in the form of a carbon tube located near the rear wall parallel to the wedge-shaped groove, connected to the end rib and at least one of the inner ribs and intended for insertion of a response tube protruding from the wing console, wherein tube inner dimension in centre section corresponds to outer dimension of mating tube extending from wing console.

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