Under the background of “dual-carbon” goals and high-quality development, green manufacturing technology is an important direction in recent years. For aircraft products, structural assembly operations account for about half of the workload during the entire aircraft, and it has a direct impact on the final performance, quality and reliability of the products. Improving the greenness degree is crucial for the transformation and upgrading of the production process and the guarantee of product quality. Firstly, green assembly technology was defined as an assembly method system that ensures the geometric accuracy and service performance of the airframe structure. Two core supporting technologies, i.e. assembly processes and quality control, and tooling equipment were proposed, with typical green characteristics such as low consumption, low emissions, high efficiency and high benefits. Secondly, evaluation indicators for structural green assembly technology were constructed. Specifically, it could analyzed from the correlation of assembly efficiency, assembly quality, assembly cost, assembly safety and the greening of tooling equipment. Then combing with specific assembly links, with the perspective of assembly process data driving on virtual pre-verification
