Analysis and experimental verification of rapid decompression in civil airplane

In the design process of civil aircraft, it is necessary to ensure that the aircraft structure can withstand the impact of the rapid decompression load when the aircraft ruptures and depresses. At present, the 0-D simulation method is mostly used to calculate the rapid decompression load. This method is based on the summary of theory and engineering experience, but the accuracy and rationality of this method have not been fully verified. Therefore, this paper measures the rapid decompression load through ground experiment for the first time in domestic, and compares the experiment results with the simulation results. The results show that the 0-D calculation method proposed in this paper is reasonable, and the direction of subsequent 0-D model optimization is also proposed.
