一种200kg级无人机载森林航空灭火弹技术研究

Technology study on a 200 kg forest aerial fire extinguishing bomb carried by UAV

为了利用无人机快速扑灭森林火灾,设计了一款航空灭火弹,重点对影响灭火效能的灭火剂、作用高度、装填比药量、爆炸分散装置结构等进行了分析、试验。通过对各种影响因素和限制条件的分析,结合灭火弹使用条件,完成了灭火弹的总体设计及试验验证,灭火面积可达400 m^(2),灭火效果较好。下一步计划在森林环境下进行实际灭火效能试验。

In order to use UVA to quickly extinguish forest fires,an aerial fire extinguishing bomb was designed.The analysis and test of fire extinguishing agent,detonate height,filling ratio dosage and explosive dispersing device structure which affect fire extinguishing efficiency are emphasized.Through the analysis of various influencing factors and restrictive condition,combined with the use conditions of aerial fire extinguishing bomb,the overall design and test verification of aerial fire extinguishing bomb have been completed.The bomb extinguishing area can reach 400 m^(2),and the fire extinguishing effect is good.The next step is to carry out the actual fire extinguishing effect test in the real forest.
