Research on Management Procedure of Material Selection and Substituting for Aircraft Parts

材料选用和替代能够有效提升飞机零组件设计中材料应用技术和管理能力,确保新研型号设计工作快速推进。本文对飞机零组件设计工作中材料应用现状进行分析,指出目前设计人员在材料应用工作中存在的问题,提出今后开展材料选用和替代工作应重点关注的技术内容以及应该遵循的工作流程;并在此基础上归纳适用于飞机零组件设计的材料选用和替代工作的技术管理程序;以某型军用飞机机体结构密封材料的选材实例和电气系统导电垫片的替代实例验证该程序的有效性。结果表明:该材料选用和替代管理程序取得了预期效果,材料替代管理程序的实施保证了生产现场状况的有序运行,同时也为航空领域及其他领域内的相关企业提供参考借鉴。

The material selection and substituting can effectively improve the ability of material application technolo⁃gy and management in aircraft parts designing,and ensure the rapid development for new aircraft design.By analyz⁃ing the current state of material application in aircraft parts designing,the application problems in designing are pointed out in this paper,and the concerned key technical and working procedure that ought to be followed by using the material selection and substituting are put forward.A technical management procedure about material selection and substituting applied to the aircraft parts designing is concluded.The examples of material selection for sealing materials of a certain military aircraft structure and the material substitution for conductive gasket in the electrical system are used to verify the effectiveness of this procedure.The results show that the material selection and substi⁃tuting management procedure has achieved the expected effect,and can ensure the orderly operation in production field conditions,and provides the relevant reference for related enterprises in the aviation field and others.
