民用飞机燃油箱点燃防护设计研究

摘要

通过研究燃油箱点燃防护适航要求的发展历程，基于对最新适航条款要求的分析和理解及燃油箱点燃防护机理分析，归纳总结了适用于民用飞机燃油箱点燃防护的设计措施，包括点火源防护、减少燃油蒸气和加装惰化系统，为民用飞机燃油箱点燃防护设计和适航验证提供借鉴和参考。%The regulatory development history of fuel tank ignition prevention was researched in this paper. Based on analysis of the latest airworthiness regulation requirement and analysis of fuel tank ignition prevention mecha-nism, design methods that applied to fuel tank ignition prevention were summarized, including ignition sources pre-vention, reducing fuel vapor and fuel inerting system. The method provides references to fuel tank ignition preven-tion design and airworthiness certification for civil aircraft.
