中文摘要:结合工程实践,针对民用航空适航规章CCAR25-R5中与材料相关的603、613条款符合性验证进行了分析和探究。首先研究了条款制定及修定的历史过程和条款的具体含义,明确了条款目的和具体要求,然后结合经验,给出了在型号合格审定过程(TC)中满足适航条款要求的方案,指出对条款的符合有两个层次方面的要求,一是要说明材料规范/标准中指标确定的合理性;二是要证明使用的材料性能指标满足材料规范/标准的要求。针对条款认可的行业规范、技术标准规定和用户规范三类规范,进一步给出了三类规范的适航符合性验证具体方法。最后结合实际情况,针对如何在TC中有效提高材料规范的适航验证工作效率,给出了三种改进工作的建议,提出材料规范的验证工作最好是单独专项进行,此项工作需要进行顶层协调规划。
英文摘要:Based on experiences from civil aircraft engineering, the item 603 and item 613 of CCAR25-R5 for materials are analyzed and investigated. Firstly, the history of the items were reviewed to receive the original intentions, as well as good understanding of the items. Then upon practices, the methodologies of material certification during the Type Certification(TC) were provided. There are two levels for the material compliance during TC. The first level is to prove the reasonability of the characteristic determinations in material specifications. The second level is to verify that the used materials in aircraft can meet the material specifications’ requirements. Furthermore, certification methods of three kind of material specifications, which are accepted by the regulations, were presented. In the end, three suggestions to improve the material certification efficiency during TC are provided. It is better for the material certifications to execute the tasks individually and specially. Top level coordinations are necessary for China’s material certifications at present.
