Sensitivity analysis for aircraft rapid decompression in cruise

In response to rapid decompression events in pressurized civil aircraft cabins during flight, we have developed a novel decompression model employing a lumped-parameter mathematical model. Our study includes a comprehensive sensitivity analysis utilizing sample-based and global sensitivity analysis methods, focusing on the impact of cockpit and vent area factors in scenarios involving windshield breaches. Results identify vent area as the primary influencing factor on pressure differentials during cruise-induced decompression events. Effective adjustment of vent areas emerges as a viable strategy for mitigating pressure differentials, offering practical strategies for intervention.
