Bird strikes are an important hidden danger threatening civil aviation flight safety. The gathering of birds in airport areas will directly affect the safety of flight takeoff and landing, and scientific and effective bird repellent measures are a necessary guarantee for the safe operation of airports. Acoustic bird repellent technology has become the mainstream solution for airport bird repellent with the advantages of no pollution, strong controllability and wide coverage. As an enterprise focusing on acoustic technology R&D, RIBRI has mature directional and omnidirectional acoustic devices, which can provide customized bird repellent solutions for airports, and comprehensively reduce bird strike risks from equipment selection, scenario deployment to long-term operation and maintenance.
Core Requirements for Airport Bird Control
Airports cover a wide area with complex scenarios. Runways, taxiways, aprons, lawns and surrounding waters are all high-frequency areas for bird activities. Traditional bird repellent methods have problems such as limited effect, easy adaptation of birds and impact on the surrounding environment, which cannot meet the long-term and stable bird repellent needs of airports. Airport bird repellent needs to meet the conditions of long-distance coverage, precise directional action, all-weather stable operation, no interference with the normal communication of airports and the lives of residents. At the same time, the equipment needs to adapt to the complex outdoor environment to ensure long-term and reliable operation.
Technical Principles and Advantages of Acoustic Bird Control
Acoustic bird repellent uses sound waves of specific frequencies and intensities to stimulate the bird's auditory system, making birds produce a sense of discomfort and vigilance, and take the initiative to stay away from the airport area. Directional acoustic devices can concentrate acoustic energy in a specified direction to achieve precise evacuation and avoid interference caused by sound wave diffusion; omnidirectional acoustic devices are suitable for large-area coverage and form a three-dimensional protection network.
RIBRI acoustic devices adopt professional acoustic design, and the sound wave frequency can be flexibly adjusted according to bird species, effectively avoiding bird adaptation. The device has an IP65 protection level, can cope with harsh outdoor environments such as rain, snow, sand, high and low temperatures, and adapts to the all-weather operation needs of airports. The device has obtained CE certification, with standardized production processes, and strict quality control from R&D to mass production to ensure the stable and long-lasting effect of bird repellent.
Case Study on the Implementation of Acoustic Bird Control at Airports
A domestic hub airport has long faced the problem of migratory bird migration and local bird gathering, with frequent bird activities at both ends of the runway and lawn areas. The effect of traditional bird repellent methods attenuates rapidly, and the hidden danger of bird strikes remains high. The airport introduced the combined scheme of RIBRI directional and omnidirectional sound waves, deployed devices at key locations such as both sides of the runway, the end of the taxiway and ecological lawns, and set the automatic start-stop and frequency switching mode according to the bird activity rules.
After the equipment was put into use, exclusive deterrent sound waves were matched for common birds such as sparrows, pigeons and egrets, and 24-hour uninterrupted protection was realized in key areas. On-site monitoring data shows that the bird staying time in the core area of the airport is reduced by 80%, the number of bird flocks breaking into the runway area is reduced by 75%, and the bird strike risk is significantly reduced. The equipment has been operating stably for more than 12 months without fault shutdown. The IP65 protection level effectively resists the impact of rainy seasons and high-temperature weather, without frequent maintenance, greatly reducing the human and material costs of airport bird repellent.
Implementation Steps of Airport Acoustic Bird Control
On-Site Survey and Scheme Customization
RIBRI technical team will conduct a comprehensive survey of the airport, clarify the bird activity areas, activity rules, main bird species and the environmental characteristics around the airport. Combined with the runway layout, flight takeoff and landing time periods, protection range and other needs, a customized bird repellent scheme will be formulated. Determine the installation location, quantity and linkage mode of directional and omnidirectional acoustic devices to realize key protection in key areas and full-area dead-corner-free coverage.
Equipment Installation and Commissioning
Complete the equipment installation according to the customized scheme, and fix it at key locations such as both sides of the airport runway, the edge of the lawn and around the control tower. After installation, carry out system commissioning, test the sound wave transmission range, pointing accuracy and working stability, optimize the sound wave frequency and working mode, ensure that while effectively repelling birds, it does not affect the airport communication, navigation equipment and the lives of surrounding residents.
Operation and Maintenance
After the equipment is put into use, it can realize automatic operation, start regularly or on demand according to the preset program, without frequent manual operation. RIBRI provides full-chain technical support, regularly inspects and maintains the equipment, and troubleshoots in a timely manner to ensure the long-term stable operation of the equipment. Staff can flexibly adjust the working parameters of the equipment according to the changes in bird activities to maintain a good bird repellent effect continuously.
