商用飞机燃油控制开关及火警提示灯设计浅析

Analysis of Fuel Control Switches and Fire Warning Lamp Design

商用飞机燃油控制开关用来控制进入发动机燃烧室的燃油,是操纵发动机的核心器件。某些型号的燃油控制开关集成有火警提示灯,主要作用是在发动机发生火情时,点亮提示灯直观提醒机组人员利用燃油控制开关进行断油操作。针对目前航线上现役机型及正在研制的商用机型进行分析,对燃油控制开关的外形结构及火警提示灯的设计、功能及逻辑设计进行初步探索。

Fuel controlling switches for the commercial airplane controlled the fuel entering into the firebox of engine,which was the core part of controlling engine. The fuel controlling switches integrated the fire lamp in some airplanes,which reminds the aircrew to shut off the fuel controlling switches when the engine is on fire. This paper analyzes the shape of the fuel controlling switches,and develops the function and the design of the fire lamp of the fuel controlling switches for the designing and servicing airplanes.
