FIRE PREVENTION AND EXTINGUISHING TECHNOLOGY FOR MANNED SPACECRAFT

his paper analyses the characteristic of firing and flaming simply,describes fire detectors for different fire condition and how to make decision properly about the kinds, number and distribution of fire detectors and build effective subsystem of fire detecting and warning. This paper also introduces three kinds of extinguishant which can be used for spacecraft, discusses how to suppress the fire and put it off,make postfire cleanup in spacecraft cabin.Howevcr in manned spacecraft the first thing we must do is how to prevent infrom firing.Finally,this paper introduces the fire detection and fire fighting system in foreign spacecraft.
