The invention relates to a forest fire fighting method and a device thereof. According to the invention, the characteristic that a rotorcraft, particularly an unmanned rotorcraft, can hover accuratelyat a fixed point, a throwing mechanism with a plurality of fire extinguishing bombs is operated to enable the forest fire extinguishing bombs to detonate on vegetation in the fireground, and the fireextinguishing bombs are sprayed in the fireground foggily according to the determined density accurately and uniformly in the form of instantaneous gas explosion, so that evaporation and escape lossis avoided; the carrying capacity ratio of the fire extinguishing agent is increased, the reliability, safety and environmental friendliness of the fire extinguishing bombs are enhanced, the forest fire fighting and prevention efficiency by the double physical and chemical fire-fighting action, it is not liable to re-combust, and the fire fighting effect is evaluated by airborne equipment; the bomb loading time of the rotorcraft is saved and the fire fighting efficiency in flight is improved; and the forest fire fighting cost is obviously reduced, and popularization and application are facilitated.
本发明利用旋翼机特别是无人旋翼机可精确定点悬停的特点,操作装有多枚灭火弹的投放机构使森林灭火弹在火场植被之上起爆,以瞬间气爆状按确定蜜度准确均匀的雾状喷洒在火场中,避免蒸发和飘逸损失;增加了灭火剂载量比,提高了灭火弹的可靠性、安全性和环保性,以物理和化学的双重灭火作用提高森林灭防火效率,不易复燃,并通过机载设备评估灭火效果;节省旋翼机装弹时间,提高了飞行灭火效率;显著降低了森林灭火成本,便于推广应用。
