FUSELAGE COMPARTMENT OF THE AIRCRAFT WITH A HATCH CUTOUT Russian patent published in 2018 - IPC B64C1/14 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering and concerns the framing of the cutout for the hatch in the fuselage compartment of the aircraft. Fuselage compartment of the aircraft with a cutout for the hatch contains an outer skin with overlays, ordinary frames and reinforced frames, located along the transverse edges of the cutout. In this case, the compartment is provided in the cutout area with an inner panel, which is shifted to the inside of the fuselage from the edges of the structure. Moreover, the inner panel is connected to the external skin by means of frames, longitudinal and sloped walls, intercostal ribs and contains a cutout for the hatch.

EFFECT: increase in rigidity of the structure in the radial direction in the zone of the cutout for the hatch is achieved, weight of the fuselage structure of the aircraft is reduced.
