History and trends in the development of safety standards for sustainable aviation fuels

摘要:
可持续航空燃料被视为航空碳减排的重要手段。航空燃料作为航空发动机的特殊部件,安全性认证是其应用的最重要前提。适航标准和燃油技术标准共同指导可持续航空燃料的发展,并形成了燃料相关的安全标准体系。为促进我国建立自主可持续航空燃料安全标准体系,对现行相关标准进行了梳理和分析。选取其中最具代表性的ASTM D4054和ASTM D7566标准,全面回顾了演变历程,总结了修订方向。研究发现:可持续航空燃料相关标准体系的修订主要集中在认证主体、审批流程、燃料性质和测定方法要求4个方面。展望了我国自主认证体系发展趋势,结合我国航空业发展现状,提出了本土产业兼容的可持续航空燃料安全认证流程,为完善我国自主可持续航空燃料安全标准体系提供了技术支持。
Abstract:Sustainable aviation fuel is considered an important means of reducing aviation carbon emissions. As a special component of aero-engines, safety certification is the most important prerequisite for the application of aviation fuel. Airworthiness standards and fuel technical standards jointly guide the development of sustainable aviation fuels and form the safety standard system related to fuels. In order to promote the establishment of an independent safety standard system for sustainable aviation fuels in China, relevant standards were sorted out and analyzed. The most representative ASTM D4054 and ASTM D7566 standards were selected to summarize the direction of revision. The research found that the revision of the sustainable aviation fuel-related standard system mainly focused on four aspects: certification body, approval process, fuel properties, and measurement method requirements. The development trend of China’s independent certification system was prospected. Combining with current development status of China’s aviation industry, a sustainable aviation fuel safety certification process compatible with local industries was proposed to provide technical support for improving China’s independent safety standard system for sustainable aviation fuels.
