AIRCRAFT CABIN WITH SECONDARY AIRCRAFT CABIN STRUCTURE MOUNTED WITH ROTARY JOINTS AND METHOD FOR MOUNTING A SECONDARY AIRCRAFT CABIN STRUCTURE IN AN AIRCRAFT CABIN

摘要

The present invention pertains to an aircraft cabin (100) comprising a primary structure (40), a secondary aircraft cabin structure (50), and a plurality of interconnecting struts (20) coupling the primary structure (40) to the secondary aircraft cabin structure (50), each of the plurality of interconnecting struts (20) comprising engaging members (21,22) at the respective end portions for insertion into strut holding fixtures (11) of corresponding rotary joints (10) attached at each opposing end. Each of the rotary joints (10) comprises an outer shell segment (1) having the outer shape of a segment of a solid of revolution, the outer shell segment (1) having an opening (4) arranged in the outer surface, an inner shell segment (2) having the outer shape of the segment of the solid of revolution of the outer shell segment (1), the inner shell segment (2) being aligned concentrically with the outer shell segment (1) and spaced apart from the outer shell segment (1) by a compensation gap, and a strut holding fixture (11) having a hollow interior and a flange portion (13) and being arranged in the opening (4) so that the flange portion (13) extends within the compensation gap between the inner shell segment (2) and the outer shell segment (1).
