Description

The invention relates to fire extinguishing and evacuation techniques, in particular to automated or automatic fire extinguishing systems (AFS) at an object by supplying fire extinguishing agents (OA) to the entire area of the object, including the burning area. The invention can be used to quickly, effectively extinguish a moving object, in particular a rapidly moving emergency landing aircraft from the moment it touches the runway (RWY) for the first time. The proposed system of multi-barrel modules (MM) can work independently, autonomously when extinguishing a moving burning aircraft along the runway, when the use of traditional, fire, airfield vehicles (PAA) is not effective or together with the PAA after the aircraft stops. Fires of crash-landed aircraft with numerous casualties up to the death of all passengers and crew regularly occur, while the PAA existing at modern airfields are able to extinguish a burning aircraft only after it has stopped. There are multiple cases of explosions and destruction of burning aircraft moving quickly along the runway, after a hard emergency landing or hit by a rocket, anti-aircraft artillery in flight, there are often hard landings on the rocking deck of an aircraft carrier in stormy weather with strong gusts of wind.

Analogues. The analogues of the invention are:

traditional automatic high-performance fire monitors with horizontal and vertical guidance, for example, manufactured by EFER, Petrozavodsk, Karelia, used to protect large objects: timber exchanges, oil reservoir parks, architectural monuments, power plant engine rooms, aircraft hangars, etc. The work of these fire monitors is provided by complex and expensive: homing systems with sensors and video complexes, high-pressure pumps and pipelines, large water tanks or a sufficiently powerful water supply system, heating pumps, pipelines, tanks in the winter. Therefore, providing a runway with a length of 3-4 km with a system of many pumps, water pipes, tanks, fire monitors with the location of the trunks no further than 50-70 m from each other is very expensive in production, installation and regular maintenance by highly qualified specialists - it is unrealistic even for very rich countries;

2 - patents of the author: No. 2008048 RU "Fire-extinguishing installation" (Russia) and No. 1263 5A UA "Zakhisna rich-barreled combined fire-extinguishing installation" (Ukraine), containing MM, with barrel channels filled in series with a mass of 15-25 liters of fire extinguishing agent (OA ) and propellant powder charge. A volley of MM barrels creates gas-drop flurries from water, gel; gas-dust Whirlwinds from powder, dust; gas-sand Tornadoes, with wide fronts up to 10-15 m, capable of extinguishing along the trajectory of up to 100-120 m of area up to S = 400-800 sq.m in 1-2 seconds. These are the only spray modules for today that create Flurries with a range, profile and Front area, capable of knocking down flames from the entire surface of the fuselage of an aircraft moving at high speed, and the runway section below it.

Prototype. Patent No. 2.726.100 Multi-barrel module of universal, impulse spraying - differs from analogue -2 in increased strength and spraying range. However, to date, MMs have not been tested to extinguish moving objects. It is necessary to carry out field tests to optimize their design in relation to the width of the profile of heavy passenger aircraft rapidly moving along the runway towards the created fire-extinguishing whirlwinds and squalls, the intervals between the location of the modules, and also to work out the tactics of oncoming extinguishing by the MM system of a burning aircraft moving rapidly along the runway.

The objective of the invention is to create an automated system of autonomous, multi-barreled modules along the runway to extinguish a moving burning emergency aircraft and, together with airfield fire trucks, to extinguish a fire of spilling aviation fuel around a stopped burning aircraft, knocking down the Flame from the fuselage, wings and cooling them. Also, according to the analysis of the available tests, it is necessary to improve the design of the multi-barrel module in a stationary version for installation along the runway.

The problem is solved by the fact that the Automatic stationary fire extinguishing system, with the executive part, consisting of stationary executive modules, characterized in that the executive part of the fire extinguishing system is located along the entire runway (runway) and is made in the form of autonomous multi-barrel modules, evenly spaced on one side of the runway or on both sides of the runway and fixedly pointing at their section of the runway; at the same time, autonomous multi-barrel modules are modules for shock-wave spraying in volleys with horizontal and vertical rows of barrels and have an electrical initiation system, spray cartridges with electric primers and sealed disposable containers are placed in the barrel channels, completely destroyed by a propelling wave in the barrel channels into fragments that do not have a striking exposure, while the containers are loaded with fire extinguishing composition completely without air cavities; when autonomous multi-barrel modules are located on one side of the runway, the entire width of the runway is covered by the front of a fire-extinguishing gas-droplet barrage created by a salvo of all module barrels; at the same time, each module is configured to be triggered when the emergency aircraft approaches the distance from which the front of the squall created by the volley of this module covers the entire width of the runway, while the modules are located in a line at distances of no more than 100 m from each other; when autonomous modules are located on both sides of the runway, the modules are placed on different sides opposite each other or in a checkerboard pattern along the entire runway, t while the modules are configured to fire in bursts, overlapping the entire width of the runway with merging squall fronts; at the same time, the modules are configured to be fired in volleys, overlapping the entire width of the runway with merging fronts; in this case, the system is configured to carry out a series of volleys, one by one, as the aircraft approaches.

In FIG. 1-3 shows: a general view of the runway fire protection executive system - 1 in the form of three layouts of spray modules - 2 along the runway - 1. In fig. 1 shows the arrangement of two modules - 2 in parallel on opposite sides of the strip - 1. In fig. 2. shows the arrangement of modules - 2 in a checkerboard pattern on both sides of the strip - 1. In fig. 3. shows the arrangement of modules in one line on one side of the strip. With different layouts, the distances between the modules change along the strip - 1. On the strip - 1, an emergency landing aircraft - 3 and the designation of the contours - 4 of the effective impact of the squall fronts, expanding along the trajectory of their movement and capturing the entire surface of the emergency aircraft and part of the strip - 1 under it and around it. Such a multilateral, effective, fire-extinguishing effect is provided on differently oriented surfaces of the aircraft - 3 and runway - 1. With the simultaneous creation of two Flurries - modules located on different sides of the runway, their fronts are combined into a common front - 5, extending far beyond the emergency aircraft and extinguishing the runway burning jet fuel, merged from the damaged tank of the aircraft - 3 along the trajectory of its movement.

Preparation of modules - 2 to work in the standby mode is carried out as follows. From the muzzle hole, porous containers are inserted into the barrels with a sprayable fire extinguishing composition (OS) liquid, viscous gel, powder or natural inert materials: soil, dirt, sand, snow, dust, previously passed through sieves to clean from random stones. The breech closures are opened, special spray cartridges with electro-igniter bushings and powder charges are inserted, the closures are closed. The serviceability of the initiating network is checked by a weak current from the control panel. After that, the modules are included in the common control network for the executive modules of the fire extinguishing system on the runway. The integrity of the system is also checked by weak currents.

This system of modules works as follows. The system is permanently on standby in a busy airport with regular takeoffs and landings, or at least before each aircraft lands if the landing becomes inadvertently aborted due to, for example, pilot error, strong winds, or other unpredictable pre-landing situation. At the moment the alarm is declared at the airport before the landing of the emergency aircraft, the system is put on high alert.

The beginning of the system operation from the moment of the beginning of a strong adhesion of the landing gear of the emergency aircraft to the surface of the runway and the rapid movement of the aircraft along it. This moment is determined by the dispatcher for video surveillance cameras and a signal is given to trigger the nearest module along the course of the burning aircraft. Further modules along the course of the aircraft are triggered automatically as the frontal part of the aircraft enters the zone of their effective extinguishing. The multi-vortex structure of the front ensures rapid extinguishing of the entire surface of the aircraft fuselage, including the wings and tail, and also eliminates the possibility of an explosion and reduces the degree of dynamic destruction of the aircraft. Also, the gas-dispersed impact of the front immediately over the entire cross section of the aircraft creates a powerful braking effect. Subject to the placement of MM-10 (5 trunks in a horizontal row x 2 rows of trunks vertically), MM-16 (8 × 2) or MM-20 (10 × 2) on one or both sides of the runway 50-100 m from each other On the other hand, the MM system can, in a series of successive salvos, knock down the flames from the fuselage, wings, tail unit of the aircraft and the inevitable re-ignition of the fuel flowing from the damaged tanks and tanks of the aircraft. Also, a series of squalls with dense fronts will significantly reduce the braking distance of the aircraft up to 2-3 times, which will allow the PAA - traditional with fire monitors and the new PAA equipped with MM-50, MM-72, MM-84 and MM-96 turrets, to start a powerful fire extinguishing attack to completely extinguish the Flame, extinguishing and solving the main task - the rapid evacuation of passengers and crew from a potentially explosive aircraft.

This system of multi-barreled modules can, for the first time in the world, provide a continuous series of powerful, large-scale fire-extinguishing squalls to ensure - (practically guarantee) the extinguishing of a burning aircraft moving quickly along the runway, prevent its explosion and destruction in motion until the aircraft stops on the runway and enters the operation extinguishing fire, airfield vehicles - traditional with fire monitors and new ones with tower multi-barreled spray modules. Such automatic fire extinguishing systems can also be used on the runways of aircraft carriers, aircraft carriers, helicopter carriers, hangars, engine rooms of power plants, including nuclear and other large fire and explosive facilities, up to large-scale extinguishing of fires of classes A, B, C, D of a wide range of sizes and power, arson, including the use of incendiary weapons.
