Fire Extinguishing Experiments on the Lithium Battery in Civil Aircraft Transport under a Variable-pressure Environment

Abstract

To investigate the thermal runaway of the typical civil aircraft-transporting lithium battery in the flight pressure environment, 3 fire extinguishing agents including 2-BTP, Novec1230 and water mist are used to launch various fire extinguishing experiments respectively under 3 pressure conditions of 80kpa, 60kpa and 40kpa. Moreover, a comparative analysis is made on the fire extinguishing performance before and after the release of the 3 agents. Lastly, this paper also analyzes the fire extinguishing effect of the 3 fire extinguishing agents from 3 perspectives: experimental phenomenon, cooling effect and smoke composition.
