Abstract

A method to dynamically drive birds with the aircraft's self-carrying ultrasonic generator on the airway in order to avoid collisions with birds is to directly arrange the broadband super-elevating wave generator at the nose of the aircraft, and directly towards the front of the airway It is realized by periodically launching different corresponding frequency ultrasonic waves (to adapt to the needs of repelling birds to various birds). The corresponding frequency ultrasonic wave can be received by more than one kind of birds and at the same time can make the bird feel irritated. obtained during the test.

Description

An aircraft with its own bird repellent

Technical field:

The invention relates to aviation traffic safety technology, in particular to the technology of direct bird repelling during the flight of manned aircraft.

Background technique:

At present, there are hundreds of aircrafts colliding with birds every year in the air and causing tragic accidents. How to prevent this problem of causing loss of life and property has always been a matter of concern to people.

Biologists have found that animals that are generally smaller or much smaller than the human body have created conditions for receiving ultrasonic waves that cannot be received by human ears due to the small or small structure of the eardrum and the relatively large thickness of the eardrum. For example: bats are small animals that can receive (hear) ultrasonic waves of a certain frequency above. As far as birds that can fly in the air are concerned, through experiments, it will be concluded that many of them can also receive ultrasonic waves of certain frequencies.

CN2626860Y discloses that an ultrasonic generator device is set on an "early warning" model aircraft (unmanned), so that it implements an indirect method of dynamic bird repelling in advance by the model aircraft for the manned aircraft (manned) channel (dynamic pre-indirect bird repelling) Reliability has been improved—the power consumption of dynamic bird-repelling equipment has been reduced), and a more indirect method to realize the pre-steady-state bird-repelling that is too indirect to the ultrasonic generator positioned on the ground (steady-state indirect bird-repellent reliability is lower than Poor - the power consumption of the steady-state bird repelling equipment is quite astonishing, and the super-large space and extensive bird repelling means: bird repelling ultrasonic waves need to cover all manned aircraft paths and much more non-airway spaces than this path for a long time).

Invention content:

The object of the present invention is to realize the improvement of the above-mentioned existing bird repelling technology through a direct airborne bird repelling device.

In order to realize the purpose of the invention, it is proposed to adopt the following technologies:

Have: broadband supersonic generator and manned aircraft, it is characterized in that: above-mentioned broadband ultrasonic generator is arranged on the position directly in front of manned aircraft, and when manned aircraft is flying, let the former be in launching and make birds feel irritated ultrasonic frequency status. - The ultrasonic frequencies mentioned are obtained during the experiment of ultrasonic frequencies capable of producing a "remote effect" on birds.

The feature that the present invention compares with prior art: because the use of the broadband ultrasonic generator that is arranged on manned aircraft head is only limited to that birds generally can reach, mainly is the limited length of low-altitude section in this manned aircraft deceleration take-off and landing process On the airway, this has created favorable conditions for greatly improving the overall effect of bird repelling (the reliability of dynamic direct bird repelling is extremely high-and the power consumption of bird repelling equipment is extremely low).

Description of drawings:

The figure illustrates the embodiment of the present invention that the broadband ultrasonic generator is arranged at the front position of the manned aircraft.

1: manned aircraft; 2: broadband ultrasonic generator, 3: ultrasonic emission direction.

Detailed ways:

Install a set of broadband and high-power directional ultrasonic generators with a directional ultrasonic emission distance greater than 10,000 meters on the nose of the aircraft. When the aircraft is flying normally, let the ultrasonic generators periodically emit towards the front of the aircraft to make birds feel The corresponding frequency ultrasonic wave of irritability orientation, the natural diffusion angle of its directional ultrasonic wave will be greater than the natural diffusion angle of directional light wave shorter than its wavelength, and the traveling speed of the ultrasonic wave in space should be equal to the sum of the speed of the wave and the speed of the aircraft, so that in the distance Once the relevant birds receiving the ultrasonic waves will leave immediately away from the direction of the aircraft route, and realize with this: extremely reliably avoid the occurrence of collisions between the birds capable of receiving the ultrasonic waves and the aircraft at high altitudes.

If a certain type of bird can receive ultrasonic waves, then there must be an ultrasonic frequency or frequency range that makes this type of bird feel irritated (for example: acting crazily or constantly screaming), and it can be easily obtained through simple experiments An ultrasonic frequency or range of frequencies that annoys a certain bird, upon receiving such an ultrasonic signal, the bird will inevitably move away from it immediately.

Obviously, the overall effect of the present invention's dynamic, direct and accurate bird repelling to prevent machine birds from colliding cannot be compared with the above-mentioned effect of using "early warning" model aircraft (unmanned) to implement dynamic indirect bird repelling in advance (there is a bird that escapes the net and breaks into the manned vehicle). The possibility of the airway of the aircraft is relatively high - the power consumption of the bird repelling equipment is not low).
