Abstract

Purpose: This study addresses the setting of the minimum detection volume for performance certification of explosives detection systems.BRMethods: The structural and material property data of the aircraft were referenced from the literature. Based on these data, a numerical analysis of the proximity explosion effect inside the aircraft was performed.BRResults: According to the numerical analysis results, approximately 440 g (approximately 270 mL) of 2,4,6-trinitrotoluene was required to destroy the Al2024-T3 sheet used as an aircraft envelope from a distance of 1 m. Therefore, to certify the performance of the explosives detection system, the minimum detection volume should be 270 mL.BRConclusion: The results of this study can be used as basic data to secure the reliability of security search equipment.
