Abstract In order to solve various bottleneck problems in aircraft development under the main manufacturersupplier patterns, learn from the ideas of modular assembly in the automotive and marine industries, the idea of modular assembly for aircraft was proposed, and the process design of modular assembly for aircraft was analyzed. Based on the design data structure modularization, system modularization, functional modularization and interface standardization, expand aircraft assembly parallel working plane by method of the aircraft top-level modular assembly process design, optimized division of work, detailed delivery status and integrated assembly, etc. Reduce the working difficulty of the final assembly stage by the work in advance, and give full play to the advantages of the main manufacturer-supplier patterns to achieve the goal of maximizing the efficiency of aircraft assembly work. Therefore, the main manufacturer-supplier patterns can shorten the total period of model development, ensure the model development node.
