The paper deals with the development of a new method for extinguishing natural fires using aircraft. Helicopters are used in the developed fire extinguishing method, from which garlands with fire extinguishing bombs are suspended. A stationary rigid frame garland, made in plan in the form of a Reuleaux triangle, is suspended from each helicopter on three cables with hooks. Each corner of the garland is connected by a rod to the corner of the central disk, made in plan in the form of a Reuleaux triangle, with a diameter within 1/5–1/10 of the garland diameter. The garland hoop with the disk is connected using rods at the corner points of similarly located Reuleaux triangles, allowing the greatest rigidity and strength of the frame structure. Rings for cable hooks are located on each rod at a distance equal to part of the rod length corresponding to the value of the second term of the series of invariants of the golden proportion, i.e. 0.618, from the point of connection of the rod with the disk. The distances between helicopters during bombing must be no less than the boundary of the fire suppression zone with bombs suspended from each helicopter. The minimum altitude of helicopters dropping bombs should be above the altitude limit for the negative impact of bomb explosions on garlands.
