Title:
航空機から消火するための方法及び装置
Document Type and Number:
Japanese Patent JP3522689
Kind Code:
B2
Abstract:
The present invention comprises supplying a liquid onto the source of a fire from an aircraft (7), wherein said liquid is supplied in the form of gas-droplet stream (8) obtained by dispersion in a gas flow and by acceleration of the dual-phase flow in a gas-dynamics nozzle (4). The pressure at the inlet of the nozzle (4) as well as the relative concentration of liquid in the dual-phase flow are selected according to conditions enabling the formation of a dual-phase low-dispersion and high-speed flow which has a high extinguishing-substance concentration and remaining stable when submitted to interference. The fire-extinguishing device of the present invention comprises a liquid supply system (1), a gas supply system (2), a mixing chamber (3) for the gas and the liquid as well as a gas-dynamics nozzle (4), wherein all these members are arranged onboard an aircraft (7). The gas-dynamics nozzle supplies the liquid towards the area of the fire source and is connected to a vessel through a duct. The mixing chamber (3) is further provided with a liquid dispersion system.
