STRUCTURE OF REGULAR ZONE OF PANEL OF WING BOX OF HEAVY TRANSPORT AIRCRAFT FROM FIBROUS POLYMER COMPOSITE MATERIALS Russian patent published in 2024 - IPC B64C3/18 B64C3/26 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to design and manufacture of streamlined structures of aircraft, in particular, wing boxes and wing devices of heavy transport aircraft. Heavy transport aircraft wing box top or bottom panels design, which are made of polymer composite material based on continuous organic and inorganic carbon and glass fibers and thermosetting matrix, in regular zone consists of smooth lining and reinforcing stringer set of T-shaped section, made with pitch (t) and height (h) of stringer. Each panel structure has cross-sectional area (F_Σ) at stringer pitch (t), which is formed from the cross-sectional area of the stringers (F_str) and the cross-sectional area of the skin (F_skin) at the pitch of the stringers (t), and when configuring the panel, an optimum distribution of the power fibrous material of organic and inorganic fibers between the stringer and the skin is made.

EFFECT: invention is aimed at improvement of strength and manufacturability of aircraft wing box panel structure.
