Systems and methods for constructing a bonded structure

A method for forming a bonded structure, the method comprising:

• positioning an outer structure and an interior structure relative to one another such that a space between the outer structure and the interior structure for receiving bonding media is provided by one or more spacers between the outer structure and the interior structure, wherein the outer structure comprises a close tolerance hole associated with a first accuracy level, and the interior structure comprises an oversized hole associated with a second accuracy level that is different from the first accuracy level;
• inserting a fastener in the close tolerance hole, the oversized hole, and in an elastomeric grommet disposed in the oversized hole, wherein the fastener comprises a channel inside the fastener having an open end at an insertion end of the fastener;
• placing a bonding media in the channel and in the space between the outer structure and the interior structure;
• and
• curing the bonding media to bond the outer structure to the interior structure, wherein the bonding media, the elastomeric grommet, and the oversized hole collectively position the interior structure relative to the outer structure.

A system for forming a bonded wing, the system comprising:

• a wing box;
• a plurality of wing ribs;
• a plurality of longerons;
• a wing skin covering the wing box, the plurality of wing ribs, and the plurality of longerons;
• and
• a plurality of bonded structures, wherein each bonded structure comprises:
• an outer structure corresponding to the wing box, wherein the outer structure comprises a close tolerance hole associated with a first accuracy level;
• an interior structure corresponding to a wing rib of the plurality of wing ribs, wherein the interior structure comprises an oversized hole associated with a second accuracy level that is different from the first accuracy level;
• an elastomeric grommet disposed in the oversized hole;
• one or more spacers between the outer structure and the interior structure providing a space between the outer structure and the interior structure;
• a fastener positioned in the close tolerance hole and in the oversized hole, wherein the fastener comprises a channel inside the fastener having an open end at an insertion end of the fastener;
• and
• a bonding media disposed in the space between the outer structure and the interior structure and disposed in the channel of the fastener, wherein the bonding media, the elastomeric grommet, and the oversized hole collectively position the interior structure relative to the outer structure.
