AIRCRAFT WITH FOLDING WING AND WING FOLDING DEVICE Russian patent published in 2020 - IPC B64C3/56 B60F5/02 

FIELD: aviation.

SUBSTANCE: group of inventions relates to aircraft engineering. Aircraft with folding wing brackets comprises fuselage; folding wing brackets; tail unit; device for folding wing brackets, made with possibility of wing brackets rotation relative to aircraft transverse axis with their subsequent folding towards tail fins along aircraft fuselage; wheeled chassis including front and main chassis; gear mechanism of main chassis wheels. Main chassis is equipped with vertical strut, installed with possibility of rotation relative to own axis, one end of which is connected to device of folding of wing brackets, and the other - with mechanism of main wheels chassis shift. Wing bracket folding device is connected with main chassis shifting mechanism by drive incorporating tie rod and two levers, includes: structural elements are made in the form of units connecting wing brackets with fixed wing part. Folding device provides displacement of wing brackets to folded position, at which plane of chords of wing bracket is vertical, and end of console is directed to aircraft tail.

EFFECT: group of inventions is aimed at increasing rigidity and strength of attachment of wing brackets in flight configuration and in a folded state.
