摘要:: 基于对CCAR33. 15 材料适航条款的分析, 以典型商用航空发动机为例, 阐述了商用航空发动机材料性能数据管理要求, 其目的是实现各类材料或基于不同制造工艺形成材料的全流程数据的管理, 包括金属材料、非金属材料、复合材料、增材制造材料、焊接结构等, 数据类型涵盖材料测试数据、材料谱系数据、统计数据及设计许用数据, 同时分析了数据存储、检索、追溯性建立、计算分析等方面的管理要求。探讨提出商用航空发动机材料数据管理要求及数据库系统的建设方案, 包括构建子库架构以满足不同材料及制造工艺的差异化数据结构需求, 建立多模块材料数据之间智能链接以实现全流程数据可追溯性, 集成材料数据统计处理程序以实现材料数据库数据读取、数据计算分析与统计数据写入的一体化等, 为商用发动机的材料符合性验证奠定数据基础。

Abstract:: The requirements of material property data management was elaborated based on the analysis of CCAR33. 15 airworthiness requirements and on the typical case of commercial aircraft engine, aiming to realize the full-lifetime management of material data of metallic materials, non-metallic materials,composite materials, additive manufacturing materials, and weld joints, whilst the requirements on the storage, searching, traceability establishing and calculation of the material test data, material pedigree data, statistical data and design allowable data was analyzed. A database system solution on materials property data management was introduced, where differentiated sub-unit with customized data structure were established for different type of materials and manufacturing processes, smart linkages across different data modules were built to meet the lifetime traceability requirements, and data calculation programs were integrated to the database system to realize the integration of data reading, calculation and writing, to finally support the materials airworthiness verification.
