摘要： The invention relates to a multipart pipe joint (10) having a centre piece (16) on which joint parts (18, 20) are received which are pivotable relative thereto and which are rotationally fixed to the centre piece (16) at articulation points (22, 24). The articulation points (22, 24) of the joint parts (18, 20) on the centre piece (16) also represent articulation points (22, 24) for transmission elements (42) which extend axially along an inner wall (34) of the centre piece (16). The articulation points (22, 24) forming articulation axes are arranged in an axial offset (25) to each other. Furthermore, the invention relates to the use of the multipart pipe joint (10) in an aircraft.

摘要： A fuel tank or bladder-free fuel tank having a reservoir on its inside area, limited to an outside area by a double-walled structure. The double-walled structure has an outer wall and an inner wall. A rib structure includes at least one rib extending inwardly into the inside area of the bladder-free fuel tank from the double-walled structure.

摘要： The invention relates to a pipe connection (10, 52, 66) with a first pipe part (12) and a second pipe part (14), with at least one multi-part sealing ring (24; 44, 46) or at least one single-part sealing ring (68) which is surrounded by a clamping device (16). The pipe parts (12, 14) each comprise a first obliquely or vertically extending end face (20, 72) or a second obliquely or vertically extending end face (22, 74). These are overlapped by a clamping device (16). This applies an outwardly acting radial force (34) to the at least one single-part sealing ring (68) or the at least one multi-part sealing ring (24; 44, 46). These are secured in their respective sealing position by means of an enclosing geometric triangle, by means of an enclosing geometric non-rectangular quadrilateral (104) or by means of an enclosing geometric rectangular quadrilateral (106).

摘要： The invention relates to a device for connecting pipe ends (80, 82) of double-walled pipes (72, 74) for angular compensation and for length compensation of the relative movements of the double-walled pipes (72, 74) relative to a double-walled connector (10). On the double-walled connector (10), there are arranged concentrically with respect to one another first and second ball heads (20, 26). These are each sealingly engaged over by ball cages (52, 54). The ball cages (52, 54) are formed on double-walled attachments (46) of the double-walled pipe ends (80, 82). The sealing function for double-walled angular compensation and double-walled length compensation are configured so as to be decoupled from one another, and are therefore optimized, in the case of the device proposed according to the invention.

摘要： A computer implemented method for planning an object which comprises a multitude of single parts and subassemblies, especially an aerospace object, the method comprising: calculating the total weights of the subassemblies and/or of the object on the basis of the data sets of the single parts and the subassemblies, wherein measured weights are used preferably to calculated weights, and calculated weights are used preferably to target weights for the calculation of the total weight(s) of the subassemblies and/or of the object, and calculating and providing the information about the shares of the used weight types in the calculated total weights. The invention further also relates to a manufacturing system and a computer implemented construction module.
