Design and Performance Analysis of a Metal Gasbag for Airborne Dispenser

doi:10.3969/j.issn.1000-1093.2017.07.025

Abstract

Abstract: Currently, the gasbag used in the external combustion type dispersion system in airborne dispenser is made of rubber/Kevlar. In view of its lower bearing strength and poorer oxidation resistance, a metal (304 stainless steel) gasbag is designed. The feasibility of the metal gasbag used in airborne dispenser is verified from two aspects of bearing strength and dispersing performance. A good performance of the metal gasbag is revealed through the static pressure bearing test. Its bearing strength is about 50% higher than that of rubber/Kevlar metal gasbag, while its weight is 45% lighter than that of rubber/Kevlar metal gasbag. And the dispersing experimental results show that the deformation of metal gasbag is symmetrical, which has little effect on bomblets' posture. Key
