据英国广播公司(BBC)4月15日报道,加拿大蒙特利尔市科学家查尔斯·庞巴迪领导的工作室最近设计出一种名叫“火焰之声”的灭火飞碟。这是一个直径接近1米、厚度约30厘米的饼状亮黄色圆盘,外壳采用复合材料等轻质材料(图一)。它可用烟雾传感器和热像仪寻找危险的火苗,在公园和森林里执行巡逻任务。低频率声波扑灭大火由于森林地处偏僻地区,一旦发生火灾人力难以企及,扑灭大火对人类来说一直是一项难以攻克的挑战(图 According to a report by the BBC on April 15, the studio led by Charles Bombardier, a scientist in Montreal, Canada, recently designed a fire-fighting flying saucer called “The Voice of Fire.” This is a pie bright yellow disc with a diameter of almost 1 meter and a thickness of about 30 cm. The shell is made of lightweight materials such as composite materials (Figure 1). It uses smoke sensors and thermal imagers to find dangerous flames and patrol missions in parks and forests. Low-frequency sound waves to extinguish the fire Because the forest is located in remote areas, in the event of a fire manpower difficult to match, to extinguish the fire for humans has been an unmanageable challenge (Figure
