Abstract

A large scale fire experiment was conducted through the collaboration between the Tokyo Fire Department and the National Research Institute of Fire and Disaster (NRIFD) for the purpose of studying the effectiveness of aerial fro fighting against urban fire. Ten model houses and ten collapsed model houses were arranged in an area of about $2,000\;m^2$. Water was dropped totally fourteen times by helicopters onto the model houses. In order to know influence of water drop, radiation was measured by four radiometers and four IR (Infrared) cameras, which were set around the burning area. In this report, the influence of aerial Ore fighting on fire was discussed in terms of irradiance and IR images. Data of irradiance, flame temperature and flame area showed that influence of each water drop continued only at most a minute.
