摘要
持续适航维修是保证民用航空发动机安全运行的重要环节。为了给评估维修品质提供参考依据,应用因素分析法,基于卡方检验方法和广义Logistic模型,提出了1种民用航空发动机持续适航维修特性评估方法。选取具有研究意义的国内主要航空公司近20年来民用航空发动机风扇叶片硬物冲击损伤持续适航维修记录数据,参考发动机维修手册中硬物冲击损伤的分类与维修方法对风扇叶片硬物冲击损伤持续适航维修特性进行分析。结果表明:维修特性涵盖的发动机类型、损伤类型与损伤处理方式等关键因素之间存在较为明显的相关性,特定的损伤类型更倾向于采用确定的损伤处理方式以满足持续适航要求。研究结果与航空公司持续适航维修方案一致,该评估方法能够为民用航空发动机持续适航维修方案的制定提供一定的工程技术参考。
Continued airworthiness maintenance is an important link to ensure the safe operation of civil aviation engine.In order to provide a reference for evaluating maintenance quality,an evaluation method for continued airworthiness maintenance characteristics of civil aviation engine was proposed based on the factor analysis method,chi-square test method and generalized Logistic model.The record data of the continued airworthiness maintenance of civil aviation engine fan blade hard objects impact damage was selected which had the significance of research in the major domestic airlines in the past 20 years.Based on the classification and maintenance method of hard object impact damage in engine maintenance manual,the continued airworthiness maintenance characteristics of hard object impact damage of fan blade were analyzed.The results show that there is an obvious correlation between the engine type,damage type and damage treatment mode covered by maintenance characteristics.Specific damage types are more likely to adopt definite damage treatment to meet the requirements of continued airworthiness.The research results are consistent with the continued airworthiness maintenance scheme of airlines.This evaluation method can provide a certain engineering and technical reference for the formulation of continued airworthiness maintenance scheme of civil aviation engine.
