摘　　要：民用飞机维修性参数选取和指标确定是维修性设计的基础工作之一,为了反映出民用飞机的维修性、运营费用和维修人力等方面的目标,需要选择合适的维修性参数并确定维修性指标。国产民用飞机由于缺少研制经验和设计资料,无法使用成熟方法进行维修性参数选取和指标确定,针对这一问题进行研究。结合民用飞机的设计特点阐述了民用飞机维修性参数的选取方法,通过综合权衡民用飞机设计中各影响因素和维修性参数有效性,从与维修时间相关、与维修工时相关、与维修成本相关的三类参数中选取适当的民用飞机维修性参数。针对民用飞机设计现状,明确维修性指标的确定依据和具有实用性的方法,以使民用飞机具有良好的维修性。解决了国产民用飞机维修性参数选取和指标确定工作无参考依据的问题,为民用飞机维修性参数选取和指标确定提供了一条可行途径。The selection of maintainability parameters and the determination of indicators for civil aircraft are one of the basic tasks of maintainability design. In order to reflect the objectives of civil aircraft maintainability, operating cost and maintenance manpower, it is necessary to select appropriate maintainability parameters and determine maintainability indicators. Due to the lack of design experience and design data, the domestically-made civil aircraft cannot use mature methods to select maintainability parameters and determine the indicators. This paper focuses on this issue. Combined with the design characteristics of civil aircraft, the selection method of maintainability parameters of civil aircraft was explained. By the tradeoff the effectiveness of various influencing factors and maintainability parameters in civil aircraft design, the appropriate civil aircraft maintainability parameters were selected from three types of parameters related to maintenance time, maintenance man-hours, and maintenance cost. In view of the current status of civil aircraft design, the basis for determining maintainability indicators and practical methods were clarified to ensure that civil aircraft have good maintainability. The research solves the problem that there is no reference basis for the selection of maintainability parameters and index determination in the domestically-made civil aircraft, and provides a feasible way for the selection of maintainability parameters and index determination of civil aircraft.
