FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used in aircraft, rocket and space engineering. Shell from composite materials 1 contains a power frame in the form of costal-honeycomb structure 2 and external shell ring 3, with reinforcement zones in the form of end frames 4 and edging of hole (hatch) 5. In cells of costal-honeycomb structure 2 formed by ribs 6 inserts 8 are arranged between layers of power elements 7 that limit cells. Depending on requirements of insert strength, including of different type of design, can be distributed in specified order on surface and/or thickness of shell.
EFFECT: use of the invention increases strength and rigidity of the shell with the costal-honeycomb frame in its local zones.
