摘　　要：电气线路互联系统(EWIS)能够实现电传系统2个或多个连接点之间传输数据的功能。相较于机械传输来说,在节约质量的同时,也带来了特殊的失效模式和风险。文中以民用电传飞机EWIS设计过程中可能出现的失效为出发点,从适航准则、安全性定量分析、区域安全性、特殊风险等方面,对EWIS系统提出相应的设计要求,以表明对适航需求的符合性。Electrical Wiring Interconnection System(EWIS)can realize the function of data transmission between two or more connection points of the Telex system.Compared with mechanical transmission,it not only saves weight,but also brings special failure modes and risks.In this paper,based on the failure that may occur in the EWIS design process of civil fly by wire aircraft,the corresponding design requirements of EWIS system are proposed from airworthiness criteria,quantitative analysis,zone safety,special risks,etc.,so as to show the compliance of airworthiness requirements.
