How to drive away the birds around the airport?

Airports, airlines, aircraft maintenance companies and other relevant departments * * * reported that there were more than 0/000 bird strikes in Chinese mainland, and the accident symptoms caused by bird strikes accounted for more than 27% of all flight accident symptoms. Bird collision has become the first symptom of an airplane accident. In order to effectively prevent bird strikes and better ensure aviation safety, airports all over the world have taken various measures to drive away birds in view of the frequent bird activities around and over airports, and achieved certain results.

Inflator: a set of humanoid materials to prevent air leakage is fastened to the blower, and the humanoid materials stand or fall down with the suction and inflation of the blower.

Bird Drive Team: Many airports have special bird drive teams. Combined with the ecological characteristics of the airport and its surrounding areas, they hold special equipment to drive away birds in densely populated areas. Sometimes, the bird drive team will use firecrackers and shotguns to drive away birds by noise.

Bird repellent car: several bird repellent devices are integrated into a car, and the bird repellent drives the bird repellent car to patrol the field.

Firecracker bomb: a device similar to a fireworks bomb is installed in the ground launcher, which is detonated when the plane takes off and lands, and the birds are dispersed by loud noise.

Gas cannon: use a device that can only make sound without causing harm. It is driven by gas and controlled by computer. Every few minutes, it will give out a "bang" and let the birds scatter.

Model: Bird repellent model uses the principle of "scarecrow" to design a humanoid model and stick it in the grass to scare away birds.

Mechanical Eagle: Install a "mechanical eagle" at both ends of the runway. When the sparrow inadvertently approached the eagle, the eagle immediately let out a loud cry and kept spreading its wings, scaring the birds to scream, flap their wings and flee quickly.

Colored wind wheel: The model of the windmill is made of colored reflective materials, which drives away the birds by rotating or reflecting light, and reflects sunlight to scare the birds away.

Attack birds with birds: use well-trained raptors such as goshawk and vulture to drive away other birds near the airport. Whether it is Charles de Gaulle Airport in Paris or JFK Airport in New York, USA, there is a bird-repelling team composed of more than 10 birds, which vigilantly guards the sky around the airport runway every day and maintains the safety of the aircraft.

Aircraft model to drive away birds: Make the toy plane look like a bird of prey and manually control it to fly over the airport, thus driving other birds out of the airport.

Sound wave to drive away birds: At the airport, directional or omni-directional long-range sound wave transmitters are used to send warning, deterrent and driving sounds to distant targets to drive away birds on the ground and in the air.

Laser bird repelling: within the airport boundary, use a laser flashlight or install a rotatable laser bird repelling device to sweep the airport with a green laser beam to force birds to fly away. Under the meteorological conditions such as dawn, dusk, rain and foggy days, the effect of laser driving birds is the most remarkable.
