Bird strike events are important factors affecting the operational safety of the aerospace field. With the development of the economic society in China, the number of times of taking off and landing of civil transportation airplanes is increased, the airplane speed is increased, the appearance is increased, the probability of bird strike is increased continuously, and the airplane has become one of main disasters in the world aviation transportation industry. It was counted that, since 1988-2014, at least 258 deaths resulted from bird strikes and other wild animal strikes worldwide, 245 aircraft crashes. Bird strike not only brings about property loss and cost improvement in aviation departments, but also directly damages the life safety of drivers and passengers, bringing about disasters of personnel and families.
In order to effectively expel birds, the prior bird catching device has certain defects when in use, and people invent different bird expelling and catching devices, and the bird expelling devices mainly comprise the following methods:
bird nets are arranged on two sides of an airport runway to prevent birds from entering a flight area. The method can effectively intercept birds flying at low altitude from entering the airport runway area, but cannot intercept birds flying at high altitude.

As shown in fig. 1-4, a novel harmless bird-catching bomb for an airport comprises a multi-petal bomb 1, wherein the multi-petal bomb 1 is made of steel, a spring assembly structure and a rear pre-pressing spring structure 12 are arranged in the multi-petal bomb 1, a catching net 7 is fixedly connected between the spring assembly structure and the rear pre-pressing spring structure 12, the catching net 7 is made of high-strength nylon, a detection fuse 10 is fixedly connected to the front end of the multi-petal bomb 1, a centering part 9 is arranged on the outer surface of the multi-petal bomb 1 at a position close to the detection fuse 10, the centering part 9 is made of nylon, a cartridge 4 is cooperatively connected to the rear end of the multi-petal bomb 1, the cartridge 4 is made of low-carbon steel, a belt 6 is arranged on the outer side surface of the multi-petal bomb 1 and at a position close to the cartridge 4, the belt 6 is made of red copper, a parachute bag 3 is arranged in the rear end of the multi-petal bomb 1, the parachute bag 3 is made of ultra-high-molecular-weight polyethylene fiber, the parachute bag 3 is fixedly connected with the catching net 7, and a stabilizer 2 is arranged on the tail part of the multi-petal bomb 1;
the inside of the cartridge case 4 is provided with primer 8, propellant powder 5 is arranged between the multi-petal elastomer 1 and the cartridge case 4, a firing device of the primer 8 after the bullet is controlled by a firing system, ignition gas generated after firing flows into a medicine room through a nozzle to ignite the propellant powder 5, high-temperature high-pressure gas is generated, and a high-pressure region is formed after the bullet to push the whole bullet system to move forwards.
The spring assembly structure comprises a spring support 15, the spring support 15 of the front end spring assembly structure is located on one side, close to a detection fuze 10, of a capture net 7 inside a multi-petal projectile body 1, a front pre-compression spring assembly 11 is fixedly connected to the side face of the spring support 15, the front pre-compression spring assembly 11 and the inner surface of the multi-petal projectile body 1 are fixed, an outer hoop 14 is arranged on the outer side of the multi-petal projectile body 1, an explosion bolt 13 is arranged on the portion, extending into the multi-petal projectile body 1, of the outer hoop 14, the rear pre-compression spring structure 12 is identical to the spring assembly structure, the projectile control system is specifically the detection fuze 10 and can be used for controlling the detonation time of the explosion bolt 13, the front pre-compression spring assembly 11 works to separate the multi-petal projectile body 1, after the front pre-compression spring assembly 11 works, the multi-petal projectile body 1 is accelerated and separated all around under the action of the front pre-compression spring assembly 11, the stiffness coefficient of the front pre-compression spring assembly 11 is larger than that of the rear pre-compression spring structure 12, the elastic force of the front spring is larger than that of the projectile body of the rear spring body, the front end is larger than that the front end spring body, and the projectile body is simultaneously, the projectile body is not stressed by the same number of the net is stable along the radial direction, and the number of the projectile body can be stably launched along the flight, and the flight ball can be stably, and the number of the projectile body can be stably loaded along the flight plane, and the flight ball can be stably, and the number of the ball can be stably and the net is stably and the impulse.
The invention relates to a novel harmless bird catching bomb for an airport, which is characterized in that when in use, when a primer 8 is excited, ignition gas is released to ignite a propellant 5 in a chamber, and the propellant 5 is burnt in a chamber to generate high-temperature and high-pressure gunpowder gas. The bullet belt 6 seals the gunpowder gas, and under the guiding action of the front centering part 9, the gunpowder gas pushes the multi-petal bullet body 1 to move forward along the axial direction until flying away from the launching tube. The bird-catching bullet flies away from the launching tube and then flies forwards under the action of the stable tail wing 2, when the detecting fuze 10 detects that the bullet moves to the vicinity of birds, the explosion bolts 13 are separated, the outer hoops 14 are broken, and the front pre-pressing spring assembly 11 is sprung to separate the multi-petal bullet body 1 to move around; because the stiffness coefficient of the front pre-pressing spring is larger than that of the rear pre-pressing spring, the front part of the projectile body expands more than the tail part, and under the combined action of aerodynamic force, the multi-petal projectile body 1 drives the catching net 7 to open to catch birds. When birds are caught by the catching net 7, resistance increases, and the multi-petal projectile 1 contracts while moving forward, and the multi-petal projectile 1 starts to fall under the action of gravity. Meanwhile, the parachute kit 3 is opened, and the unfolded parachute kit 3 provides larger air resistance; because the resistance of the multi-petal elastomer 1 is smaller, the multi-petal elastomer is at the bottommost end in the falling process, and simultaneously drives the opened capturing net 7 system to slowly descend; when landing, the multi-petal elastomer 1 lands firstly, and the catching net 7 and the parachute bag 3 which carry the birds are slowly landed, so that the birds are caught in a harmless manner.
The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
