FIELD: machine building.
SUBSTANCE: invention relates to a compound of sections of acoustic cellular structure, with formation of adhesion acoustic cellular and can be used for suturing curved sections of acoustic honeycomb structure with formation of engine nacelles and other acoustic weakening oscillations structures. Combined cellular structure contains first section, having first and second edge, multiple walls extending between edges, and forming a plurality of cells, first side, with multiple protruding walls, each of which has end wall, having length extending between first and second edges, and thickness; second section containing first and second edge, multiple walls extending between edges, and forming a plurality of cells, second side, with multiple protruding walls, each of which has end wall, having length extending between first and second edges, and thickness; and seam arranged between first and second sections, adhesively connecting first and second side of cellular structure, joint comprises adhesive for binding with ends of walls of first and second sides of cellular structure and support for adhesive, which is a support seam cellular structure and contains first edge located near first side of cellular structure, and second edge located nearby second side of cellular structure, multiple walls extending between first and second edges support joint, and forming a plurality of cells seam, adhesive is arranged in cells of joint.
EFFECT: invention provides strong and flexible joints and preservation of acoustic properties of structure.
