Research Abstract

In case of a great earthquake disaster, wide area urban fire would be expanded for lack of firefighting water supply from road destruction, hydrant damage and so on. If airplanes, such as a helicopter, can be used under specific conditions, it would be effective for firefighting. Airplanes can arrive at the fire site in a short time, and fire fighting can be carried out quickly. For this reason, it would be expected for aerial fire fighting by a fire-fighting helicopter for urban fire in case of a great disaster. However, about the fire extinguish or deterrent effect by aerial firefighting, there is no enough research work for urban fire. Until now, the real scale experiment used by real helicopter was carried out by National Research Institute of fire and disaster. It is difficult to carry out the real scale experiment frequently. Therefore, in this research, small model experiment was proposed and similarity with a real scale experiment was verified. As a result of this research, it was reproducible about the air spread phenomenon which was dropped water from the bucket. Furthermore, some information of the method of an effective aerial firefighting was obtained.
