Abstract

Today, structural parts of aircrafts are put together by fasteners (rivets) by the following process: • Moving towards each other and positioning • Temporary fastening and drilling • Moving parts apart and clean chips in interface area between parts • Sealing with sealant substrate • Final positioning and riveting with fasteners.

The purpose of the proposal is to leave the expensive positioning station as soon as possible, in order to improve the critical path in structural assembly of parts of all sizes. Today, positioning stations are used only for a relatively short period of time for their original function "positioning". The approach is to secure a permanent fix connection between parts and to allow tact-operation out of the station very quickly, in order to make maximum use of the positioning function of the station and not to block by drilling and riveting. The major step change can be achieved, when the whole drilling and riveting operations would be applied totally outside the positioning station in a much simpler and cheaper station.

 Moving parts apart and clean chips in interface area between parts  Sealing with sealant substrate
 Final positioning and riveting with fasteners.

The purpose of the proposal is to leave the expensive positioning station as soon as possible, in order to improve the critical path in structural assembly of parts of all sizes. Today, positioning stations are used only for a relatively short period of time for their original function "positioning".

The approach is to secure a permanent fix connection between parts and to allow tact-operation out of the station very quickly, in order to make maximum use of the positioning function of the station and not to block by drilling and riveting.

2. DISCLOSURE

The solution to join structural parts of aircrafts is to use adhesive bonding glue, which also fulfills a sealant function. This allows establishing a solid, gapless structural connection between two parts, which allows a direct drilling in one way.

Today, industrial adhesive bonding glues (e.g. two components) create very high adhesive forces on very small surfaces in comparably short tim...
