Description

The invention relates to the fire protection technology, in particular aircraft, especially airships, which are used in the extinguishment of larger fire.

Fire-fighting methods are known in the use of aircraft, in particular of airships such as AN-32P, BE-12P-200, BE-200P [ "Fire Extinguisher", year 2003, No. 1, 2. ]. A disadvantage of these methods and devices is the quite considerable complexity of the aircraft control. Another disadvantage is that waters that allow a water extraction in gliding, not always be near fire herds. The fundamental disadvantage of these methods and devices is the high price of the technology itself and its use.

Also known is the fire service airship [ RU 2250122 ] comprising a discus-shaped aerostatic hull, a reversible vector thruster drive train, a crew compartment with control equipment, an anchoring means and a cargo compartment accommodating a water tank with a spout which is part of the cargo space mounted device which makes water packages; which are intended for ejection to the burning area by a hatch.

The firefighter airship closest to the present invention (prototype) includes a discus aerostatic hull, a propulsion and propulsion system with reversible vector thrust, a ballast system, a crew compartment with a control system, a cargo hold with a water tank, and a pumping device. which is intended to pump water into the container for further delivery to given fire zones [ RU 2342177 ]. The main drawback of the prototype is its discus design and, consequently, a relatively high "sail" (cross section) against powerful turbulent thermals that always emerge in the zone of a forest or steppe fire, extensive inflammation in industrial plants or residential neighborhoods. The discus-shaped design substantially complicates the controllable positioning of the airship over the predetermined point of the fire because of the high sail of the airship, and the fire extinguishing effect is consequently reduced because the accuracy of the extinguishing agent is reduced to the object to be deleted.

Another disadvantage of the prototype is that the flight of an airship is to be conducted directly by a human, for which safe and relatively comfortable conditions must be created on the airship. It must be ensured a corresponding life assurance system, the weight of the airship is relatively large together with the plane and quite a lot of energy costs.

• – eine Effizienzerhöhung des Feuerlöschens aufgrund der präzisen Lieferung von Löschmitteln in die vorgegebenen Feuerzonen;
• – eine maximale Betriebssicherheit des Luftschiffs unmittelbar über dem Feuerherd, weil die Besegelung des Luftschiffs gegenüber den mächtigen turbulenten Thermiken unter Bezugnahme auf die aktuelle klimatische Windbelastung bei Beibehaltung der Kapazität des Luftschiffs wesentlich sinkt und die Ortsänderungen sowie das Feuerlöschen vom Luftschiff als unbemannte, ferngelenkte Drohne vorgenommen werden können.

The technical result of the invention comprises the following points:

• - an increase in the efficiency of fire extinguishing due to the precise delivery of extinguishing agents to the specified fire zones;
• - Maximum operational safety of the airship immediately above the hearth, because the sails of the airship against the powerful turbulent thermals with reference to the current climatic wind load while maintaining the capacity of the airship significantly decreases and made the changes of location and extinguishing the airship as an unmanned, remote-controlled drone can be.

• – einem klassischen halbstarren Zigarrenrumpf, dessen Oberschale mit einer Schutzabdeckung gegen die Wärmebelastung der Feuerzone beschichtet ist;
• – einem Antriebssystem für die Energieversorgung der Bordsysteme, Geräte und der Ausrüstung;
• – einem Vortriebssystem mit einem umsteuerbaren Vektorschub;
• – einem Ballastsystem für die Auftriebsänderung des Luftschiffs und dessen einzelnen Teile;
• – einem PC-Flug-Steuerungssystem mit der Soll-Flugbahn und der Sollgeschwindigkeit, der Positionierung des Luftschiffs insgesamt und dessen achsiger Lageregelung im Soll-Raumpunkt, das einem sich in Sicherheit (auf der Erde oder in einem anderen Fluggerät) außerhalb der Feuerwirkungszone aufhaltenden Menschen das Luftschiff führerfrei per Funkverbindung zu steuern ermöglicht, und das mit einem Informationssystem ausgerüstet ist, das im sichtbaren Spektrum und im Ultrarotspektrum funktioniert, wodurch der vorgegebene Informationsumfang bezüglich der Objekte, die sich außerhalb des Flugschiffs befinden, einschließlich der erforderlichen Angaben hinsichtlich der Feuerherde sowie der Kenngrößen von Funktionen der Systeme und Bauelemente des Flugschiffs sichergestellt wird;
• – Frachträumen mit Wasserbehältern, die sich im Luftschiffbug und in der Luftschiffmitte befinden;
• – einem Pumpensystem, um ohne Aufsetzen des Luftschiffs auf die Wasseroberfläche Wasser in Behälter zu pumpen für die präzise Wasserstrahlrichtung zum vorgegeben Punkt der Feuerzone sowie für die Wasserrichtung teilweise zum Luftschiffsbug als Spray, um dessen Rumpf vor schädlicher Wämeeinwirkung durch die Feuerzone zusätzlich zu schützen.

The technical result is achieved by the fact that the fire-brigade airship consists of the following components and systems:

• - a classic semi-rigid cigar hull whose top shell is coated with a protective cover against the heat load of the fire zone;
• - a propulsion system for the power supply of on-board systems, equipment and equipment;
• A propulsion system with a reversible vector thrust;
• - A ballast system for the buoyancy change of the airship and its individual parts;
• - A PC flight control system with the desired trajectory and the target speed, the positioning of the airship in total and its achsiger attitude control in the desired point in space, the one in safety (on Earth or in another aircraft) outside the fire zone the airship can be controlled by radio without a driver, and is equipped with an information system operating in the visible and ultra - spectral ranges, thereby reducing the amount of information relating to the objects located outside the ship, including the information required for the herd of fire and the Characteristics of functions of the systems and components of the airship is ensured;
• - cargo holds with water tanks located in the bow of the airship and in the middle of the airship;
• - A pump system to pump without placing the airship on the water surface water in containers for the precise water jet direction to the given point of the fire zone and for the water direction partly to Luftschiffsbug as a spray to protect its hull from harmful heat through the fire zone in addition.

The above-mentioned components and systems of the airship can be used in some establishments.

Operation 1: Monitoring, patrol, observation

In this operation, water tanks in cargo holds are empty. The airship flies in a "classic" way, whose fuselage axis is close to the horizontal position. The location change of the airship to the target trajectory is performed by the operator, who is on the ground or in another aircraft, by means of the propulsion control system, the ballast system and the information system.

Operation 2: Filling the water tanks

In this operation, the airship positions itself above a pool of water, and the containers are filled with water by means of a hose and a compression pump. The control system, the propulsions, the ballast system and the information system secure the target location and the spatial direction of the airship, taking into account its general payload change.

Operation 3: Movement of the airship from the pool to the fire zone

In this operation, the airship moves according to the operator predetermined path from the starting location to the set point, similar to the movement in operation. 1

Operation 4: Fire fighting

In this operation, the airship positions itself above the set point of the boundary of the fire zone and, by activating the ballast system as well as other systems, assumes the position in which the A-axis of its fuselage is close to the vertical, whereby a minimal sail against the mighty turbulent thermals is ensured. Furthermore, the airship moves in the vertical position above the fire zone on the prescribed path by the surgeon. Using all systems of the airship, the surgeon performs a targeted fire fighting, the airship deliberately descends above the target range of the fire zone in a dive (decreases as long as it is possible for security reasons) and a water jet by means of a water blower, the in the airship bug whose longitudinal axis is arranged, directed from the bow container targeted at this area, while water is sprayed at the same time partly from special nozzles as a spray on the bow surface of the hull of the airship.

Each of the above-mentioned features of the offered invention is known and has been implemented several times in practice individually and in various combinations, but the use of these features in the described connection reveals the surplus effect which consists in attaining the above-mentioned new technical result.

In Figure 1, the schematic structure of the airship is shown in section. The number of propulsions and their concrete arrangement on the fuselage is determined according to concrete measurement data of the airship (dimensions, load capacity and so on). The hoses for the water extraction and the compression pumps are housed inside the airship and are pushed out only when operating the water pumps. The number of camcorders and their specific arrangement on the fuselage are determined by the specific purpose of the airship and its measurement data.

Pictures 2 and 3 show possible fire extinguishers.
