ADAPTIVE WING Russian patent published in 2024 - IPC B64C3/44 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering and relates to adaptive wings transformable bearing surface design, said adaptive wings allow preset smooth variation of surface shape at aircraft carcass mating sections with better aerodynamic characteristics. Aircraft adaptive wing consists of aerodynamic structure. Aerodynamic structure includes a support structure and an outer coating. Support structure has a fixed beam in the longitudinal direction, which passes from the central zone to the outer end zone. At that, support structure has several adaptive segments of frame in transverse direction, which consist of adjacent triangular compartments formed by fixed rod elements, and adjustable along the length of adjustment elements. Frame segments are connected to the fixed beam, and at least part of the triangular compartments has at least one side of the adjustable elements on one side, so that the frame segments are adjustable in shape. Note here that outer coating is secured in frame segments to vary aerodynamic structure outer contour in crosswise direction.

EFFECT: invention aims at increasing efficiency and enlarging the control range of aerodynamic characteristics of the wing with simplification of control systems.
