Research on the flow performance of airborne flame arrestor

摘要

Airborne flame arrestor, which can effectively prevent flame propagation and spread so as to earn more evacuating time for passengers and crew, has been widely applied in aircraft ventilation system. In this paper, five main forms of flame arrestor element are discussed and their advantages and disadvantages are analyzed. Flow performance of these elements is calculated. The results show that the flow performance of crimped ribbon, metallic honeycombs and Cellular ceramics types are better than that of parallel plate and perforated sheet.
