FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to the design of openings. The aircraft main structure comprises the reinforcing opening structure as well as the skin, frames and stringers. Note here that reinforcing structure comprises the perimeter reinforcing element arranged along the opening edge to reproduce the opening shape, two crosswise reinforcing elements arranged on both sides of the opening, two reinforcing elements located on both lengthwise sides of the opening. Note here that the lengthwise reinforcing elements are composed of the stringers that feature larger depth in the opening edges.
EFFECT: ruled out extra elements and parts of integrated structure of higher structural efficiency.
