新型民用客机水系统选型研究

民用飞机水系统的功能是在飞行中为机上乘客提供饮用水、盥洗用水和马桶冲洗用水。水系统作为飞机上与乘客生活息息相关的系统，舒适性的要求越来越被关注。目前，飞机上使用的水系统方案各式各样，对于不同的飞机需求，各种方案各有各的特点。针对国际新型飞机上已经开始采用的水系统的各种方案进行了权衡研究，重点研究了水系统几种控制方式的优缺点以及机电综合控制技术作为新技术在新型民用飞机上的应用，同时介绍了灰水的几种处理方式、比较常用的几种水龙头以及其优缺点分析。针对某种飞机型号，根据飞机的市场定位和需求，介绍了如何选择一套合适的系统方案，来提高该飞机的经济性和实用性，为我国民用飞机水系统的研制提供一定的参考。

Research on Types of Water System for New Civil Aircraft

The function of water system of civil aircraft is to provide the potable water, washing water and toilet flashing water for passengers in flight. As a system related to passenger＇s living, the comfort of water system is increasing concerned. Various water system configurations are used by existing airplane. Each configuration has different characteristic for various aircraft requirements. The various optional water system configuration used by worldwide advanced airplane, mainly including the advantage and disadvantage of several control method of water system, and the application of integrated electrical mechanical to advanced airplane as a new technique are analyzed and researched; and several grey water disposal method and common faucet, and their advantage and disadvantage are introduced. For an aircraft project, a right system configuration can make the aircraft more economical and applicable to meet various market orientation of the aircraft. It can be the reference in our civil aircraft water system design.
