Experiment Study on the Distribution Characteristics of Fire Extinguishing Agent Concentration in Helicopter Fire Extinguishing System
This article conducted experimental research on the concentration diffusion of fire extin-guishing agents in helicopter fire extinguishing systems,and analyzed the extinguishing agents sprayed under different unit volume ventilation,different fire extinguishing agents,and different pressure states.Through experimental research on time and distribution characteristics,the influence of unit volume ventilation on the maintenance time of fire extinguishing agent concentration and the influence of unit volume ventilation on concentration change rate were analyzed.Measures for leaving a large de-sign margin when the unit volume ventilation was less than 1.32 kg/(s·m3)were proposed.
