航天飞船地面试验舱灭火系统设计

Design of Fire Protection Systems for Test Cabin of Space Shuttle

针对低气压和富氧的条件,航天飞船试验舱灭火系统选用基于高效冷却作用的Novec1230和细水雾系统。结合工程设计,介绍了两种系统的灭火机理、工艺流程、系统组成、控制方式以及灭火特点等。

Due to the condition of low air pressure and rich oxygen, the fire protection systems for test cabin of space shuttle adopt Novec1230 and water mist based on highly efficient cooling function. Combined with the project design, the extinguishing mechanism, technological process, system composition, control mode and extinguishing characteristics of Novec1230 and water mist fire protection system are presented.
