民机电气线路互联系统（EWIS）维修性设计研究

摘要

This paper clarifies the EWIS scheduled and un-scheduled maintenance tasks of aircraft in service ac-cording to the concept of the Electrical Wiring Interconnection System ( EWIS) as a special functional system of the aircraft, relying on the type development practice. Based on this, some special maintainability qualitative require-ments were presented, a set of new process and method of allocating the maintainability requirements to EWIS de-sign zones were innovatively delivered, and some feasible means of EWIS maintainability evaluation or verification were studied.%依照将EWIS作为飞机独立功能系统的研制理念，从型号工程实践中出发，分析明确了飞机运营中EWIS的计划和非计划维修工作任务，并在此基础上创新性地提出了针对EWIS维修性设计的定性要求、结合EWIS组件的设计特点提出了以EDZ为对象进行维修性设计要求分解的方法，以及型号研制中开展EWIS的维修性分析与评估验证的方法。
