Abstract: The invention relates to a method for producing at least one fuselage cell of an aircraft with the following steps: at least partial production of surface protection and thermal insulation in the region of the at least one shell part, at least partial introduction of technical outfitting systems 1-3, 10-12, 22-24, 46-48, in particular of electrical and hydraulic lines, air-conditioning lines, electrical and hydraulic appliances, sanitary and catering equipment or the like, into the at least one shell part and/or the at least one floor grid 13, 41, and assembly of the at least one shell part and of the at least one floor grid 13, 41 into the at least one fuselage section 32.

Abstract: Methods and apparatuses for ensuring the dimensional constancy of multisegment physical structures, in particular aircraft structures, during assembly are disclosed. The method includes setting up a spatially-fixed three-dimensional coordinate system which encloses the subsequent assembled physical structure and introducing a plurality of segments of the physical structure to be assembled into the spatially-fixed three-dimensional coordinate system. The method includes recording the positions of the individual segments and the positions of already assembled groups of segments repeatedly within the spatially-fixed three-dimensional coordinate system during assembly.

Abstract: The invention relates to a method for ensuring the dimensional constancy of multisegment physical structures, in particular aircraft structures, during assembly, having the following steps: a spatially-fixed three-dimensional coordinate system (90) which encloses the subsequent assembled physical structure is set up; a plurality of segments (31, 32, 33) of the physical structure to be assembled are introduced into the spatially-fixed three-dimensional coordinate system (90); the positions of the individual segments (31, 32, 33) and of already assembled groups of segments (31, 32, 33) are recorded repeatedly within the spatially-fixed three-dimensional coordinate system (90) during assembly; and the position of a respective segment (31, 32, 33) or of a respective already assembled group of segments (31, 32, 33) is corrected if a respective record shows that the positions of the respective segment (31, 32, 33) or of the respective already assembled group of segments (31, 32, 33) is outside a tolerance band, whi

Abstract: The invention relates to a method for joining at least two aircraft fuselage segments (2, 3) by friction stir welding with a tool (8) generating friction heat for the partial plasticisation of an edge region (6, 7) of at least one of the two aircraft fuselage segments and a counter bearing (10) for absorbing the force exerted by the tool (8) on at least one of the two aircraft fuselage segments, wherein at least one of the two aircraft fuselage segments comprises at least one rib (17) and/or one stringer (16). In order to minimise the necessary expense incurred in association with the production aids for the FSW process, it is proposed that the at least one rib (17) and/or the at least one stringer (16) of the at least one aircraft fuselage segment (2, 3) should be used as a counter bearing (10).

Abstract: A method for making a silicic acid containing rubber base composition includes providing composition ingredients of rubber, silicic acid, silane and additional additives except for vulcanization ingredients. First and second mixers separate from each other are provided wherein the ingredients except for the vulcanization ingredients can be mixed. All of the composition ingredients are introduced into the first mixer except for the vulcanization ingredients simultaneously or at time intervals. The composition ingredients introduced into the first mixer are mixed to a composition. The composition formed in the first mixer is transferred directly into the second mixer without an intermediate storage thereof. The transferred composition formed in the first mixer is mixed at least almost to completion in the second mixer with the temperature lying in the temperature range of 130° C. to 180° C.
