Pressure-Bulkhead-Integration with a DNC-Riveter in a Widebody-Rear-Section 931759

This paper describes the application of an automated process for installing dome-type pressure bulkheads into the rear section of widebody airplanes by use of a new CNC-controlled multi-axis drilling and two-piece fastener installation machine.
The system basically consists of a DNC/CNC drilling and fastening machine and an assembly jig for the aircraft rear section.
The workhead performing the drilling, sealant application and fastener installation travels on a circular ring around the fuselage section. The required counteraction force for installing the interference fit fasteners is provided by the support system, which works on the inner side of the fuselage.
The purpose of the unit is to provide an automatic system with the goal of increasing the consistency of the quality of assembly by simultaneously reducing cost.
