摘　　要：维修性设计是民用飞机研制工作中的基础工作之一,维修性的好坏直接影响到民用飞机的经济性和市场竞争力。我国民用飞机维修性设计工作起步较晚,缺少系统的正向方法和技术指导资料。将系统工程实践应用于民用飞机设计过程中,进行正向设计,可以尽可能减少设计工作量,减少返工。将利益攸关方的维修性需求落实到系统设备的维修性设计中,对于民用飞机的维修性设计至关重要。以民用飞机电子电气舱的维修性设计为例,通过需求识别,以需求权重为基础计算得到维修性设计要求的相对重要度。再用关联矩阵法将维修性设计要求落实到民用飞机系统设备的设计上。该方法采用正向设计,为设计出满足用户需求且易于维修的民用飞机提供了设计思路。Maintainability design is one of the basic works in the development of civil aircraft. The quality of maintainability directly affects the economy and market competitiveness of civil aircraft. The maintainability design of civil aircraft in China started late and lacks systematic forward design methods and technical guidance materials. Applying the practice of system engineering to the design of civil aircraft for forward design can reduce the design workload and rework as much as possible. Implementing the maintainability requirements of stakeholders into the maintainability design of system equipment is crucial to the maintainability design of civil aircraft. Taking the maintainability design of the electrical and electronic cabin of a civil aircraft as an example, the relative importance of the maintainability design requirements is obtained based on the demand weight through demand identification. Then, the maintainability design requirements are implemented into the design of the civil aircraft system equipment by the incidence matrix method. This method adopts forward design, which provides a design idea for designing a well-maintained civil aircraft to meet the needs of users.
