A bolted repair for curved surfaces of an aircraft structure (10) includes a plurality of relatively thin, flexible plates (14, 16, 18, 20) that are bent to conform to the surface, either individually or as a group. After the plates have been bent to conform to the surface, layers of adhesive (15) are applied between adjacent plates to bond the plates to each other. The resulting stack of bonded plates is then secured to the structure with fasteners extending through attachment holes in the stack and structure. The plates may be bent by first securing a portion of a stack of plates to the structure and then bending the stack of plates so that the plates progressively conform to the surface of the structure. As areas of the stack of plates conform to the surface of said structure, the areas are temporarily secured to the structure with temporary fasteners (34, 38, 42, 44) until the entire surface of the stack of plates has been bent to conform to the surface of the structure. After layers of adhesive are applied between adjacent plates and all of the temporary fasteners have been installed so that the entire surface of the stack of plates conforms to the surface of the structure, the temporary fasteners (34, 38, 42, 44) are sequentially removed and permanent fasteners are installed in their places. |
