Abstract: Against the problems of high-rise building fire, such as many fire hazard sources, dense personnel, special structure, and combining with hexa-rotor UAV,fire-fighting bomb, fire identification technology, theoretical study and on site test, a set of drone equipped with fire-extinguishing bomb system was developed, which is fast, efficient, safe and reliable. Tests showed that, hexa-rotor UAV carrying fire-fighting bomb can fly steadily and precisely launch the bomb, while the reaction force of launching can be overcome by self-power of the drone; after launching, the bomb fly according to the scheduled route steadily, and explosive at the set position; the best distance of explosion and fire source is 3~5 m, which can ensure the dispersion of the extinguishing agent.

Key words: fire-fighting, hexa-rotor UAV, fire-fighting bomb, flying control, fire monitoring
