Aircraft assembly, as the main component of aircraft manufacturing, bears the capacity of 40%–50% of the whole machine manufacturing. Among them, aircraft unit assembly is a powerful guarantee of aircraft quality, flight safety, cost and delivery cycle. The main characteristics of unit assembly are large size of parts, easy deformation of sheet metal parts or composite parts, complex assembly process, etc., which will produce assembly clearance or interference and other out-of-tolerance problems, especially in the unit joint area. In order to solve the above problems, SACC optimizes the unit assembly docking process of the mid fuselage in certain large airliner. This paper first introduces the status of the gap or interference in aircraft assembly, and investigates the main technical reasons and strategies. Secondly, combining with the situation of assembly in mid fuselage, from the aspects of assembly datum, unit precision and process allowance optimization and using the assembly tolerance analysis and the method for theoretical calculation of dimension chain, SACC finally realizes the breakthrough in mid fuselage assembly problems and efficiency. A solid foundation has been laid for improvement of customer satisfaction and meeting the delivery orders.
