Problems solved by technology
[0008] The disadvantage of the known devices is the small amount of water placed in the tank, or the relatively short hose for water suction, which limits their use during fire fighting, requiring more flights to the fire site to fill the tank from the source Conveying water, or known devices not intended for use in helicopters equipped with landing gear

The invention relates to a helicopter with a fire extinguishing system and the fire extinguishing system. The helicopter contains fuselage (2), tail beam (3), carrier system (4), power plant (5), landing gear (6), and a fire extinguishing system. In the lower part of fuselage (2), under the floor of the transport cabin, water tank (8) is located in compartment (9). The inner cavity of water tank (8) is divided into four compartments (10, 11, 12, 13) by means of keel longitudinal beam (14) and transverse diaphragm (15), equipped with bypass valves (16), while compartments (10, 11, 12, 13) of tank (8) are connected in pairs diagonally. In its lower part, tank (8) is equipped with flaps (20) connected to electric drives (21), in addition, heating elements are located along the contour of flaps (20).
Description
technical field [0001] The invention relates generally to the field of aircraft engineering and, more specifically, to the design of helicopters equipped with fire suppression systems. Background technique [0002] Known firefighting helicopters (patents RU2347596, B64D1 / 16, A62C31 / 28 published on 27.07.2006) present in their fuselage tanks for storing fire extinguishing liquid, with liquid release in the front of the lower compartment device, and in the main tank of the extinguishing liquid, there is a restrictive movable plate, whereby displacement of the center of gravity of the liquid in the tank is excluded. [0003] A device for airdropping liquids from a helicopter is known (patent US6578796, IPCB64D1 / 16, published on July 4, 2002), comprising a liquid container fixed under the fuselage of the helicopter, equipped with a Liquid hinged doors. A water supply hose with a pump is attached to the container. A rotating element with an electric drive is provided, connecte...
