RU2740440C1 - Method for scarlet feathering during takeoff of aircraft - Google Patents

Abstract

FIELD: agriculture; protection of airports against birds.

SUBSTANCE: method of frightening feathery during takeoff of an aircraft consists in the fact that corridor is formed from continuously flashing light beams and continuous outbreaks of signal rockets. Said corridor is formed immediately before takeoff aircraft along its course from divergent beams of light (9) from three projectors (6) fixed on fuselage (1). Corridor operates throughout the entire passage of aircraft hazardous due to feathered zone.

EFFECT: higher safety of aircraft takeoff.

Description

The invention relates to agriculture and to the field of airport security from birds.

Known projects: "A method of non-traumatically dangerous scaring away wild birds and a device for its implementation", invention RU 2348152, C2, IPC A01M 29/00, 03/10/2009 Byull. No. 7 and "Ecological gun", invention RU 2460290, C2, IPC А01М 29 / 00.10.09.2012 Byull. No. 25.

The disadvantages of well-known projects are their very limited range and low efficiency.

The objective of the present invention is to develop a simple and reliable method that ensures safe takeoffs (landing) of aircraft at airfields in the presence of birds in the takeoff (landing) zone.

The problem is solved by the fact that additional equipment is installed on the aircraft fuselage, with the help of which it is possible to form a corridor in front of the aircraft (along its course) of continuously flashing light beams and continuous flashes of signal flares.

The following are installed on the aircraft fuselage:

1) strong searchlights (3 pcs.) With a range of at least 500 m;

2) two machine guns firing signal flares with a range of up to 400 m;

3) additional signal (side) lights on the sides of the fuselage and at its top.

Using the flashing light beams of searchlights and flashes of signal flares fired from machine guns, a light corridor is formed along the course of the taking off aircraft, which acts for the entire takeoff time and scares the birds off the course of the taking off aircraft.

The claimed invention is illustrated by drawings, where Fig. 1 is a general view of the aircraft, front view; in FIG. 2 - General view of the aircraft, side view; in FIG. 3 - the course of the beams of the searchlights and the flight path of signal flares; in FIG. 4 - cross-section of the path of the beams of the searchlights and the flight path of signal flares, at a distance of 100 and 500 meters from the aircraft; in FIG. 5 - longitudinal section of the searchlight; in FIG. 6 - cross section of the searchlight; in FIG. 7 - an enlarged fragment of the aircraft, front view; in FIG. 8 is a general view of a container with machine guns inside.

On an aircraft consisting of a fuselage 1, wings 2, tail unit 3, engines 4 and cockpit 5, additional equipment is installed.

Three searchlights 6 are attached to the fuselage 1 (one searchlight above the cockpit 5, and two searchlights 6 under the wings 2 on both sides of the fuselage 1).

On both sides of the cockpit 5, two machine guns 7 are attached to the fuselage 1.

On the fuselage 1 (on both sides and on the roof) additional parking lights are attached.

Diverging rays of light 9 from three searchlights 6 form a triangular-shaped light corridor in front of the aircraft taking off. The cross-section of the corridor 100 m from the aircraft in FIG. 3 and FIG. 4, is designated by the number 11, and 500 m from the aircraft - by the number 12. The flight paths of signal flares fired from two machine guns 7 are indicated in FIG. 3 and FIG. 4 with the number 10.

The beam of light 9 from the lamp 13 of the searchlight 6 is focused by the reflector 14 and is repeatedly interrupted for a short time by the rotating shutter 15, rigidly set on the axis 16, which is hinged on two supports 17. The axis 16 rotates on the supports 17 by the motor 18. The machine gun 7 for firing signal flares is fixed in casing 19, which is attached to the fuselage 1 under the windows of the cockpit 5.

The functioning of the method of scaring away birds is as follows.

In the presence of birds in the airfield area (according to the controller, according to the aircraft locator), during takeoff, before the aircraft takes off from the runway, the pilot turns on (with a button) the protective system. On the fuselage of the aircraft, 3 searchlights turn on and two machine guns firing signal flares begin to fire, and additional flashing signal lights on the sides and on the roof of the aircraft fuselage light up.

Three beams of light from three searchlights form a permanent flashing light corridor of a triangular shape in front of the aircraft taking off (along the course of its movement) in diameter up to 500 m long and 40 m wide at a distance of 100 m from the aircraft and up to 200 m at a distance of up to 500 m from the aircraft.

Two machine guns simultaneously fire along the longitudinal axis of the luminous corridor with signal flares at a frequency of two rounds per second (with each machine gun). The powder charge in the signal cartridge (signal flare) is designed for a firing range at a distance of up to 400 m. Before an aircraft taking off along its course at a distance of 400 m from the aircraft, two signal flares are constantly flashing at intervals of 0.5 seconds. The aircraft's takeoff speed is up to 300 km / h or 80 m / s. It turns out that signal flares flash 400 m from the aircraft every 40 longitudinal meters, and the lateral distance between flashes of two signal flares is up to 50 m at a distance of 400 m from the aircraft. The plane reaches the place of the signal flare flash (400 m) after 5 s, during which the flare flares down and, leaving the light corridor, frees it for the plane's flight. In front of the aircraft taking off, a permanent flashing light corridor is formed up to 500 m long and 40 m 100 m wide from the aircraft to 200 m 500 m from the aircraft.

Inside this luminous flashing corridor along its longitudinal axis, 400 m from the aircraft, two signal flares flash every 40 longitudinal meters and at a distance of 40-60 m from each other in diameter. In addition to this light and pyrotechnic cacophony, additional marker lights along the sides and on the fuselage roof are flashing in the light corridor on the aircraft taking off. This constant glowing and flashing light corridor, with constant flares of signal flares inside, is guaranteed to scare birds off the course of a plane taking off. This will allow avoiding collisions of birds with the aircraft when it rises to a height of 2-3 km, where there are no birds, it takes 2-3 minutes.

After the aircraft climbs to this altitude, the pilot turns off the protective system and the aircraft continues flying in the normal mode.

Implementation of the claimed method of scaring off birds before an aircraft taking off will not require large expenses. It is simple in execution and effective, and allows you to exclude participation in the "Russian roulette" with a forced hard landing of the aircraft on the "cornfield" with full tanks and its subsequent dismantling.

Claims (1)

A method of scaring away birds during an aircraft takeoff, which consists in forming a corridor of continuously flashing light beams and continuous flashes of signal flares, characterized in that the said corridor is formed directly in front of the aircraft taking off along its course with the possibility of its action throughout the entire passage of the dangerous aircraft because of the feathered zone.
