航空锂电池适航审定规章解读及符合性方法研究

锂离子电池作为动力电池有着优异的性能,在民航行业上有广阔的应用前景。但行业对其技术特征 和安全风险的认识还不充分,现行的规章条款缺乏足够的安全要求,国外局方针对锂离子电池颁发了专用条 件,但回顾相关事故可以发现,锂离子电池的验证和审查环节还不完善,相关条款更新修正的步伐也同锂电池 的发展现状和技术水平不相适应。以航空锂电池事故为例,分析航空锂离子电池作为动力电池的安全性风险, 从对现有规章条款和专用条件的解读出发,借鉴不同行业近年来积累的锂电池验证和使用经验,针对航空动力 锂电池的适航符合性方法提出一些改进方案,可作为现有锂电池适航符合性方法的有益补充,为自主建立健全 适航验证规范体系做出探索。

Interpretation of Airworthiness Certification Regulations and Research on Means of Compliance for Aircraft Lithium Ion Battery

With the best comprehensive performance, Li-ion batteries are going to be widely applied to civil aviation. As the research of its technical characteristics and security risks was defective, and the applicable airworthiness regulations were short of safety standards, foreign administrator issued special conditions, which containing the additional safety standards. Nevertheless, the investigation report of li-ion batteries fire in aircraft showed that the validation and certification of li-ion batteries were defective, and the update of standards fell behind the development of lithium-ion batteries. This paper analyzed the risk of li-ion batteries as s aviation power, interpreted existing regulations and special conditions, and provided suggestions for airworthiness means of compliance. Combined with experiences of service and verification, these suggestions will supplement airworthiness means of compliance, improve the verification standard system, and explore the autonomous foundation of standards.
