    摘要:

    民用飞机维修性的好坏直接影响到市场竞争力,是民用飞机成功运营的关键因素之一。维修性预计是民用飞机研制过程中维修性设计的主要工作之一,能够评价设计是否满足维修性要求。抽样评分法作为维修性预计的方法之一,具有样本量小、预计简便、设计初始阶段即可应用的优点。电源系统为飞机的所有用电设备供电,其维修性的好坏直接影响机载设备能否正常运行,对整机的维修性设计起着关键作用。对抽样评分法展开研究,并根据民用飞机维修性设计现状,量化了维修要求的人为因素评分核对表,对抽样评分方法进行了优化。通过抽样评分法对某机型电源系统的维修性进行了预计,评价是否达到维修性设计要求。最后阐述了抽样评分法在民用飞机维修性设计过程中的重要性。

    Abstract:

    The maintainability of civil aircraft directly affects market competitiveness and is one of the key factors for the successful operation of civil aircraft.The maintainability prediction is one of the main tasks in the civil aircraft development process,which can evaluate whether the design meets maintainability requirements.As one of the methods of maintainability prediction, sampling scoring method has the advantages of small sample size, simple prediction and can be used in the initial stage of design.The power system supplies power to all electrical equipment of the aircraft, and its maintainability directly affects the normal operation of the airborne equipment, and plays a key role in the maintainability design of the whole aircraft.This paper studies on the sampling scoring method, and according to the current status of civil aircraft maintainability design, quantifies the human factor rating checklist for the maintenance requirements.and the sampling scoring method is optimized. In this paper, the maintainability of the electrical power system of a certain aircraft type was estimated by sampling scoring method, and whether it meets the maintainability design requirements is evaluated.Finally, the importance of sampling scoring method in the process of civil aircraft maintenance design was expounded.
