Abstract:
1. A method for assembling a dome-shaped pressure bulkhead on a one-piece, substantially conical tail section for an aircraft, wherein the tail section has a connection region and an end region, the method comprising: a) connecting an edge angle formed by a plurality of edge angle segments to the pressure bulkhead; b) horizontally receiving a prefabricated tail section in a horizontal placement area, wherein the tail section comprises a longitudinal axis; c) introducing the tail section into a swivel frame, wherein the tail section is rotatable by the swivel frame about its longitudinal axis from its horizontal position to a vertical position, wherein the swivel frame receives and holds the tail section inside a portion of the frame; d) swivelling the tail section using the swivel frame from the horizontal position into the vertical position, with the connection region of the tail section pointing upwards e) horizontally positioning and centering the pressure bulkhead on the connection region; and f) joining the pressure bulkhead to the tail section in the area of the connection region, wherein a transverse butt strap formed by a plurality of transverse butt strap segments is connected to the connection region of the tail section and the pressure bulkhead is centered and connected to the transverse butt strap, and wherein immediately after horizontally positioning and centering the pressure bulkhead on the connection region the transverse butt strap is partially fastened to the edge angle of the pressure bulkhead to fix the position.
