Томские ученые создали установку для отпугивания птиц от аэропорта

Bio-acoustic bird repeller, new type has developed in Tusure. The device allows to effectively deter birds from airfields with a focused acoustic beam and the reproduction of alarm signals, the press service of the University.

Installation, works as a sound cannon, does not cause lethal harm to living beings, but effectively affects their behavior.

“Developed by our research team, the device allows you to influence birds using acoustic signals of high power in the direction of the runway. We direct the acoustic beam at the flock of birds that are exposed to the strongest sound effects and leave the territory. Our device acoustic stimulation can be applied directly prior to takeoff of the aircraft to scare birds away from runways, — said Professor of the Department of radio systems Nikolai p. Krasnenko. — The use of this technology does not cause concern to others, passengers and airport staff – acoustic radiation is generated in a narrow sector, which significantly reduces the impact of sound on people that are close to the zone of operation”.

The plant can operate in the traditional mode of bioacoustics repeller, reproducing the alarm signals of birds. Thus according to its specifications it is more powerful and more reliable than existing counterparts. Commonly used systems consist of piezoelectric or electrodynamic horn loudspeaker, stationary or mobile, with a small range According to the developers, the main disadvantages of the systems used is relatively low power, short range and sensitivity to weather conditions.

Developed in TUSUR device of acoustic effect based on a different principle – this is not an isolated horn speakers and antenna array consisting of many individual radiating elements. The system is devoid of the disadvantages of conventional systems and has benefits such as greater range, high signal level, directivity effects and high frost resistance.

Note, the problem of preventing collisions of birds with aircraft is one of the urgent problems for the staff of the airfields. So, in June 2016, the Airbus A320, carrying out flight Tomsk – Moscow, was forced to return due to hit the engine of the poultry, and in July the An-24, Tomsk flying from Surgut, made an extra circle before landing due to birds on the runway. As a result of incidents nobody has suffered. And the airline “Globus”, which is a holding company of S7, has filed a lawsuit against OOO “Tomsk Airport” with a demand to pay compensation for getting birds into the engine Boeing 737.
