民用飞机防火系统研究

摘要

The fire protection detection system of a civil aircraft consists of detection system, fire extinguishing system. Fire protection system is able to detect fire, monitor some areas, and give a warning about overheating, smoke or fire for designated protection area. Once it detect dan- gerous situations such as overheating, smoke or fires in protection zones, the system will give a warning to the pilot so that he can adopt corresponding processing program. The system can provide fire extinguishing measures to restrain or extinguish fire, ensuring the safety of the aircraft and people. The system can detect the working state of the equipment, make fault diagnosis, display and record system failure during a flight and make fault isolation. On the ground and during flight, the system provides measures to make crew test equipment state, ensuring the normal operation of the system and the safety of the plane.%防火系统由探测系统和灭火系统组成。色机防火系统对指定防护区的过热、烟雾或着火状况进行探测、监控和告警，并提供有效的灭火或者火情抑制措施。一且探测到防护区发生过热、烟雾或火情等危险情况，系统向驾驶员发出告警，以便驾驶员采取相应处理程序。系统提供灭火措施，可对火情进行抑制或扑灭，保证飞机和人员的安全。系统对设备的工作进行状态监测和故障诊断，显示、记录飞行过程中的系统故障并进行故障隔离。在地面和飞行中，系统应提供措施使得机组人员能对设备工作进行测试，确保系统的正常运行，保证飞机的安全。
