Abstract:In this paper, the advantages and disadvantages of the three kinds of alignment methods, i.e, upper and lower maneuvers, left and right maneuvers and composite maneuvers techniques, were firstly discussed. The key coordination control points and the key technology involving in the assembly process are pointed out. Finally, four major assembling difficulties, including the control and detection of the theoretical shape of the aircraft head assembly, the position and degree of assembly of the front landing gear cabin, the deformation and plane control of the frame components, and the positioning and deformation prevention technology of the cockpit frame and the floor were sorted out, and corresponding solutions and key techniques were also introduced in the paper.
Key words:aircraft head assembly;alignment methods;coordination control point
