FIRE-FIGHTING METHOD APPLIED VIA A FIRE-FIGHTING TUBE CARRIED BY THREE FLYING MULTI-PROPELLR AIRCRAFTS

摘要

Novelty: an air-born fire-fighting system is disclosed. Technical features: three flying multi-propeller vehicles and an air-born fire-fighting tube connecting the water sources to the fire front. The flying vehicles (1,3) retain the front and rear ends of said fire-fighting tube which hangs, via netting, from the rope 1 being held and controlled by the radially-arranged ropes of the automated rope reels. Hanging from the vehicle 3, the main water pump absorbs the necessary water quantity to be supplied to the fire-fighting tube and therefrom discharged via an automated hose or vat on the fire front. The flying vehicle E is the main vehicle and is characterised by one main propeller 1 and two auxiliary main propellers (2,3) rotated by independent motors in the opposite direction with regard to the main propeller 1 while the propellers (4,11) are assisting the automated navigation of the main vehicle E. The flying vehicles (A,D) constitute two alternatives of the main flying vehicle E.
