摘要
The corrosion and fatigue tests of a certain type of aircraft fuselage panel lap structure were conducted alternatively. Based on the test results and the concept of aircraft structure life envelope, the life envelope of the lap joint structure of the fuselage panel in different service areas and under different flight intensities was established. Then, based on this life envelope, the remaining lifetime of the structure was predicted. The prediction error was found to be 17.4% by comparing the experimental results with the calculated results. It is shown that the structural life envelope is a powerful tool for life prediction of aircraft typical lap structures, and its prediction result is an important reference for the maintenance cycle and life management of aircraft in service. © 2023 Beijing University of Aeronautics and Astronautics (BUAA).
