摘要/Abstract

摘要： 目前应用于机载布撒器外燃式子弹药抛撒机构的气囊主要由橡胶/芳纶材质构成，针对其承压强度较低、耐氧化性较差的不足，设计了一种金属材质（304不锈钢）的抛撒气囊。分别从承压强度和抛撒性能两方面开展静态承压试验与动态抛撒试验，以验证其用于抛撒系统的可行性。静态承压试验结果表明，壁厚0.2 mm的金属气囊膨胀过程具有良好的气密性，承压强度比橡胶/芳纶复合材料气囊提高了50%左右、质量降低了约45%；动态抛撒试验结果显示，该结构金属气囊的膨胀形变过程具有良好的对称性，且对抛撒姿态影响很小。试验结果可为金属气囊在机载布撒武器中的工程实际应用提供参考。

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
