FUSELAGE OF AIRCRAFT Russian patent published in 2019 - IPC B64C1/12 

FIELD: aviation.

SUBSTANCE: invention relates to the field of development of aircraft structural structures using polymer composite materials, in particular to the power structure of the fuselage compartment of a civil aircraft in the dimension of near- and medium-haul liners of both cylindrical shape and different from it, and can be used for aircraft engineering. Aircraft fuselage comprises, in lower part, at least to level of passenger floor, outer metal lining with reinforcing set and transverse beams of cargo floor, side parts of shell, passenger floor and upper part of shell. Side parts of the shell are formed by panels of variable curvature of increased stiffness. Passenger floor is made as load carrying element with formation of closed power frame in lower part of fuselage. And the upper part of the shell is made with lower rigidity relative to the closed load-bearing frame.

EFFECT: higher strength of the structure.
