FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. aircraft structural component comprises sheets with recessed areas and strips along inner surfaces of the latter, structural elements, means for jointing sheets with structural elements. Joint comprises internal and external members to make a dovetail and a lock. One of said members is arranged along strips of said sheets while another one is arranged at sections of structural elements aligned with said strips. Said lock prevents relative sliding between internal members and external members of said dovetail joint. Said internal members are furnished with ledges and recesses arranged in turns in every side edge. Said external members are furnished with ledges and recesses arranged in turns in every side edge. Number, position and sizes of said recesses and ledges are selected to make reliable joint there between. Said ledges and recesses as-assembled are located opposite each other.
EFFECT: simplified assembly, decreased weight, sufficient stiffness.
