摘要
客改货飞机主货舱相比于原客机下部货舱,舱容更大,装载货物种类更多,一旦发生火灾事故,不仅货物受损,还会危及飞行安全,因此必须为主货舱配置防火系统.通过对条款的研究,分析总结主货舱防火系统的组成与设计要点.以单通道窄体客改货飞机为例,提出了一种由烟雾探测器、烟雾探测系统控制器和指示告警系统组成的主货舱烟雾探测系统架构,梳理了系统内设备的功能、性能与布置要求,并提供了一种验证主货舱烟雾探测系统性能的数值计算方法.根据条款要求,明确了主货舱火情抑制的主要措施与要求,针对机组人员在飞行中可能进入的客改货飞机主货舱,确定了手提式灭火器的布置要求.
Abstract
Compared with the lower cargo hold of the original passenger aircraft,the main cargo hold of the passen-ger to cargo aircraft has a larger capacity and more types of loaded cargo.Once a fire accident occurs,not only the cargo will be damaged,but also the flight safety will be affected,so it is necessary to configure the fire protection system for the main cargo hold.This paper analyzes and summarizes the composition and design points of the main cargo compartment fire protection system based on the research of aviation regulations.This paper proposes a main cargo hold smoke detection system architecture composed of smoke detectors,smoke detection system control unit,and indication alarm systems.This paper sorts out the function,performance and arrangement requirements of the equipment in the system,and provided a numerical calculation method to verify the performance of the main cargo hold smoke detection system.According to the requirements of the regulations,this paper specifies the main meas-ures and requirements for fire suppression in the main cargo compartment,and this paper determines the arrange-ment requirements of portable fire extinguishers for the main cargo compartment of the passenger to cargo airplane,which is accessed by the crew during the flight.
