民用飞机研制阶段EWIS构型管理

2007年底FAA发布新的规章修正案，将电气线路互联系统（electrical wiring interconnection system,简称EWIS）的适航要求以独立分部 H分部的形式纳入FAR 25部运输类飞机适航标准，将EWIS提升到飞机的一个重要综合系统来看待，其研制过程需进行系统性的考虑，EWIS的构型管理成为适航取证的重要关键环节。结合EWIS研制特点阐述了EWIS构型管理面临的挑战，分析并研究了EWIS构型管理的类别及关键内容，提出了管理策略建议，对于民用飞机EWIS的研制具有现实指导意义。

EWIS Configuration Management for Civil Aircraft Development

Electrical wiring interconnection system (EWIS) as a part of FAR 25 regulation is issued in the end of 2007, which requires EWIS shall be considered as an important integrated system of aircraft, and EWIS development shall comply with systematic methods. EWIS configuration management (CM) is an essential part for certification. This paper introduces the features of EWIS development accompanied with the challenges for EWIS configuration management. The objects and key contents of EWIS configuration management are analyzed and studied. The strategy methods are presented. This paper can be very helpful to guide EWIS development for civil aircraft.
