国外民机EWIS设计先进理念的介绍与探讨

Introduction and Discussion of Advanced Concept of EWIS Design

随着适航新规章的发布,电气线路互联系统(EWIS)在整个民机设计体系中愈发得到重视。国外在EWIS设计方面已形成了非常专业化的体系,通过四个典型实例介绍了国外在EWIS设计中的先进理念,并探讨了对国内EWIS设计的借鉴意义并提出了相关建议。这些典型实例包括:EWIS适航认证、EWIS部件可靠性分析、EWIS安装设计标准制定、EWIS总体布局设计。

As the issuance of new airworthiness regulations,Electrical Wiring Interconnection System（EWIS） attracts more attention in the design of civil airplane. There forms an very specific system in EWIS design in the foreign countries. Here introduced the advanced concept of international EWIS design by typical four examples and discussed the significance of using this for reference and the related suggestion was given as well. The typical examples include：EWIS airworthiness certification,EWIS components reliability analysis,EWIS installation design standard establishment and EWIS general layout design.
