民用飞机第23.867条款要求及适航审定研究

Requirements and airworthiness certification of CCAR 23.867 for civil airplane

随着越来越多先进复合材料应用在民用飞机上以及民用飞机上使用的电子电气设备重要度和集成度越来越高,飞机的闪电防护设计越来越重要。CCAR-23第23.867条对民用飞机机体结构闪电直接效应防护进行了规定。研究了该条款的制定和修订的背景和历程,明确了条款的实质要求。23部飞机的使用用途和设计特点使得23部飞机的闪电防护设计和符合性验证也有自己的特点,为此,重点研究了23.867条款的基本设计、审定步骤和审查关注要素等,梳理出了飞机机体结构的闪电直接效应防护设计和适航审定的基本流程,给出了可接受的符合性方法,提出了23部飞机闪电直接效应防护设计、审定各流程的主要工作、可指导或可参考的文件、重点关注要素和技术审查要点,为民用飞机的闪电直接效应防护的设计和适航审定提供了参考。

As the application of more and more advanced composite materials in civil aircraft and the increasing importance and integration of electronic and electrical equipment used in civil airplane,the lightning protection design of airplanes becomes more and more important.The 23.867 of CCAR 23 gives the airworthiness requirements of the lightning protection for civil airplane’s airframe structure.This paper studies the background and process of the formulation and revision of the clause,and clarifies the substantial airworthiness requirements of the clause.Due to the differences in use and design characteristics between the part 23 airplane and the other airplanes,there are still differences in lightning protection design and compliance verification between them,so the basic process of airworthiness certification of lightning protection against direct effects,and the acceptable means of compliance were given for the part 23 airplane,The principal activities,reference documents,key concerns and technical points of lightning protection design and certification process were put forward,which provides a reference for the design and airworthiness certification of lightning direct effect protection for civil aircraft.
