HIGH-SPEED AIRCRAFT WING COMPARTMENT HULL Russian patent published in 2022 - IPC B64C1/00 

FIELD: aircrafts.

SUBSTANCE: invention relates to the field of aircraft, namely to the structures of the hulls and aerodynamic surfaces of high-speed aircraft (HSAC) using composite materials. The body of the wing compartment of the HSAC is designed to ensure docking with the wing consoles and includes an outer body made of carbon composite material, an inner metal body connected to it and thermal insulation placed between them, the outer body consists of a shell and a wing center section, frames are installed in the shell, and in the center section - transverse walls adjacent to the frames on the outer side of the shell, while all elements of the outer body are connected using fasteners made of carbon composite material, followed by siliconization of the outer case, and the inner case is made in the form of a front frame, shell and rear frame rigidly connected to each other, with at the same time, on the side of the rear frame, the outer and inner casings are rigidly connected, and on the side of the front frame, the outer casing is in contact with the inner casing with the possibility of thermal displacement.

EFFECT: use of the proposed invention will make it possible to design and manufacture full-functional structures of the hulls of the wing compartments of the HSAC, operating under the influence of high-temperature air flow and aerodynamic loads, as well as to design and manufacture the structures of the external heat-shielding hulls of the HSAC.
