项目摘要

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.

在发生大地震灾害时，由于道路损毁、消火栓损坏等原因导致消防供水不足，城市火灾范围会扩大。如果飞机，如直升机，可以在特定条件下使用，它将有效地灭火。飞机可在短时间内到达火场，迅速进行灭火。因此，在发生重大灾害的情况下，可以使用消防直升机对城市火灾进行空中灭火。然而，关于空中灭火对城市火灾的灭火威慑作用，目前还没有足够的研究工作。到目前为止，真实直升机的真实规模试验是由国家火灾灾害研究所进行的。经常进行真实规模的实验是很困难的。因此，本研究提出了小模型实验，并验证了与真实规模实验的相似性。研究结果表明，空气扩散现象是可复制的。此外，还获得了有效的空中灭火方法的一些信息。
