摘要
Abstract
Materials and processes form the foundation of manufacturing development,especially for civil aviation products,whose design,verification and airworthiness certification are inseparable from the support of material data.Despite significant progress in domestic material and process technologies in recent years,material airworthiness certification of civil aero-engines still faces the challenges of insufficient verification data due to an incomplete material system and inadequate accumulation of historical data.The current primary contradiction is manifested as the conflict between the high requirements of civil aircraft airworthiness for materials/processes,the insufficient support capacity of the domestic material system,and the urgency of solving problems.This paper analyzes the core requirements of airworthiness regulations such as CCAR33.15"Materials",compares the current situation of domestic and foreign material/process airworthiness certification,and identifies gaps of China in material specification statistical validation,process control mechanisms,design allowable value generation and special processes.Combining practical issues in certification practice,a technology scheme based on national conditions is proposed.Relying on the national collaborative innovation mechanism,a five-dimensional implementation path of"Regulation interpretation-system collaboration-multi-party linkage-technical synergy-dynamic adaptation"is constructed.It promotes the improvement of enterprise material systems through type projects and accurately acquires verification data oriented toward design requirements.Practice shows that this scheme has promoted the completion of over 600 material and process tests,established more than 100 material specifications and over 1000 design performance curves,effectively supporting the type certification work.The research results provide technical references for improving the management of material/process airworthiness certification of civil aero-engines and promoting the application of independent materials.关键词
