Description

Technical Field

[0001] This application relates to the field of aircraft assembly production lines, specifically to a dual-aircraft hybrid mobile assembly production line and a hybrid mobile assembly method. Background Technology

[0002] To rapidly meet the demands of the defense and civil aviation markets, capture market share, and maintain market advantage, the pace of new aircraft development has been continuously accelerating. The time required for production preparation to manufacture one aircraft has been reduced from approximately two years at the beginning of this century to the current six months. The aircraft assembly line is one of the most crucial links in aircraft production preparation. Its preparation is technically challenging, complex, time-consuming, and requires significant investment. To date, due to both market demand and technological capabilities, all domestic and international aircraft mobile assembly lines have adopted single-aircraft, single-line technology. Companies like Boeing and Airbus, having already established market advantages, have relatively large production volumes for single-model aircraft and therefore have little need for multi-aircraft mixed-line technology. However, Chinese aircraft manufacturers, whose production volumes for single-model aircraft are relatively small, have also had to resort to single-aircraft, single-line technology due to technological limitations. However, the problems brought about by single-aircraft single-line technology are becoming increasingly prominent. Large investment should correspond to large output, but now some of my country's new aircraft have "customized" features and "targeted" uses, and the output is relatively limited. At the same time, rapid delivery is required, and aircraft manufacturers also need to consider profitability. The current single-aircraft single-line technology has problems such as weak compatibility, low utilization rate, and high investment cost, which can no longer meet the low-cost, high-compatibility, and agile manufacturing needs of aircraft manufacturers.
