Description

Technical Field

[0001] This utility model relates to the field of bird deterrence equipment, specifically a high-altitude bird deterrence projectile used in conjunction with a launcher. Background Technology

[0002] Bird deterrent munitions are generally used in the open outdoor environments of airports to disperse flocks of birds above the runways. Existing bird deterrent munitions are generally cylindrical in shape, with an ascent distance of approximately 50-100 meters. While their deterrent effect on low-flying birds is undeniable, they are ineffective against high-flying birds. Furthermore, existing bird deterrent munitions are prone to rotation or tumbling during ascent due to airflow, causing their ascent path to deviate and resulting in detonation outside the designated location, failing to achieve a precise, fixed-point explosion. Utility Model Content

[0003] This invention addresses the technical deficiencies mentioned in the background section by providing a high-altitude bird deterrent projectile with an ascent height of approximately 300-350 meters and an ascent path that is less prone to deviation.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is: a high-altitude bird deterrent projectile, comprising a projectile head and a projectile body connected together, wherein explosive charge is filled inside the projectile head and the projectile body. The projectile's head is a hollow conical structure; the projectile body is a hollow structure, comprising an upper cavity, a middle cavity, and a lower cavity; the upper cavity is a two-section structure, comprising an upper cylindrical structure and a lower frustum structure; the middle cavity is a cylindrical structure; the lower cavity comprises an upper frustum structure and a lower cylindrical structure; a channel is provided inside the projectile body, penetrating the middle cavity, with its upper end connected to the bottom of the upper cavity and its lower end extending to the upper section of the lower cavity; a detonator is provided inside the channel; tail fins are evenly distributed around the periphery of the lower cavity; the two ends of the detonator are respectively connected to the explosive charge in the upper cavity and the propellant in the lower cavity.

[0005] As a preferred technical solution: the projectile head has an arc-shaped top surface and a stepped connecting joint at its bottom, which is inserted into the upper cavity of the projectile body.

[0006] As a preferred technical solution: the length of the projectile head accounts for 1 / 5 to 1 / 6 of the overall length of the bird deterrent projectile; in the main body of the projectile, the length ratio of the upper cavity, the middle cavity and the lower cavity is 2:1:2.

[0007] As a preferred technical solution: the frustum structure of the upper cavity has an angle of 15-30° between its outer wall and the central axis.

[0008] As a preferred technical solution: 4-6 tail fins are evenly distributed around the periphery of the lower cavity of the projectile body; the upper edge of the tail fin is a slanted edge with an angle of 45-60° with the central axis, and the outer edge is a straight edge.

[0009] As a preferred technical solution: in the frustum structure of the lower cavity, the angle between its outer wall and the central axis is 15-30°. As a preferred technical solution: in the frustum structure of the lower cavity, the upper part is an extended channel, and the lower part is a large-diameter flared structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The shape of the projectile's head and body has been improved. The conical design of the head and the streamlined proportions of the body can greatly reduce the resistance during the projectile's ascent and increase the ascent height. The detonation height can be adjusted between 100m and 350m, which can be controlled by adjusting the length of the fuse. 2. A tail fin was added to improve the stability of the missile during flight, maintain its attitude at launch, ensure that the missile's flight trajectory is not easily affected by external airflow and deviate, increase the straight flight altitude, and achieve a fixed point and altitude explosion. 3. It has a wide range of applications, not only for dispersing birds in outdoor airport environments, but also for fireworks displays, solving the problem of directional pattern display during fireworks displays.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] See appendix Figure 1-6 The bird-repelling projectile disclosed in this utility model is an improvement on the existing bird-repelling projectile, specifically including a projectile head 1 and a projectile body 2 connected together. The projectile head 1 is a hollow conical structure. The projectile body 2 is a hollow structure, including an upper cavity 2-3, a middle cavity 2-2, and a lower cavity 2-1.

[0020] In this embodiment, the upper cavity 2-3 is a two-section structure, comprising an upper cylindrical structure and a lower frustum structure. The middle cavity 2-2 is a cylindrical structure, and its diameter is smaller than that of the upper cavity 2-3 and the lower cavity 2-1. The lower cavity 2-1 comprises an upper frustum structure and a lower cylindrical structure.

[0021] A channel 2-4 is provided inside the projectile body 2, penetrating the middle cavity 2-2. The interior of the middle cavity 2-2 is part of the channel 2-4. The upper end of the channel 2-4 connects to the bottom of the upper cavity 2-3, and the lower end extends to the upper section of the lower cavity 2-1. A fuse 4 is installed inside the channel 2-4. Tail fins 3 are evenly distributed around the periphery of the lower cavity 2-1. The two ends of the fuse 4 are connected to the explosive charge in the upper cavity 2-3 and the propellant in the lower cavity 2-1, respectively. The projectile head 1 and the interior of the upper cavity 2-3 are filled with explosive charge or effect charge, and the lower section of the lower cavity 2-1 is filled with propellant. See Figure 6 (The projectile head and projectile body are not shown in the figure.) The figure shows the installation positions of the explosive charge 5, the fuse 4 and the propellant 6.

[0022] In a preferred embodiment, the projectile head 1 has an arc-shaped top surface and a stepped connecting joint at its bottom, which is inserted into the upper cavity 2-3 of the projectile body 2. After the explosive charge is filled, the two are glued together.

[0023] Preferably, the length of the projectile's head 1 accounts for 1 / 5 to 1 / 6 of the overall length of the bird-repelling projectile; in the projectile body 2, the length ratio of the upper cavity 2-3, the middle cavity 2-2, and the lower cavity 2-1 is 2:1:2. The upper cavity 2-3 has a frustum structure, with its outer wall forming an angle of 15-30° with the central axis. The upper, middle, and lower cavities are connected by a smooth curved transition. The conical design of the head and the streamlined proportions of the body can greatly reduce drag during the projectile's ascent and increase its ascent height.

[0024] Preferably, 4-6 tail fins 3 are evenly distributed around the periphery of the lower cavity 2-1 of the projectile body 2. The upper edge of each tail fin 3 is beveled, forming an angle of 45-60° with the central axis, while its outer edge is straight. The length of the tail fins 3 matches the length of the lower cavity 2-1. The tail fins improve the stability of the projectile during flight, maintain its launch attitude, and ensure that the projectile's flight trajectory is not easily deviated from due to external airflow interference.

[0025] In the frustum structure of the lower cavity 2-1, the angle between its outer wall and the central axis is 15-30°. This frustum structure has an upper part that extends into the channel-4, and a lower part that is a flared structure with thinner sidewalls and a larger diameter. The lower section of the lower cavity 2-1 is a cylindrical structure with the same inner diameter as the flared section of the upper part.

[0026] The following specific embodiments illustrate the method of using this utility model: (1) Fill the launch tube with propellant 5, generally in a quantity of 3g; (2) Place the bird deterrent bullet, which is filled with explosive and propellant and is firmly bonded, into the launch tube, with the two ends of the fuse in contact with the propellant and explosive respectively; (3) The propellant is ignited by electronic ignition at the bottom of the launch tube, the projectile is launched, the propellant ignites the fuse, and as the fuse burns to the explosive charge area, the projectile explodes.

[0027] In practical applications, to ensure standardized specifications, the propellant and fuse are usually measured in fixed quantities. The bird-repelling projectile disclosed in this invention, under the same propellant and fuse conditions, achieves a flight altitude of approximately 300-350 meters, significantly increasing flight altitude. Furthermore, it maintains a consistent attitude during flight, without rotation or tumbling, enabling directional, fixed-altitude detonation within a fixed area, without disturbing unintended detonation zones, thus greatly improving accuracy.

[0028] To flexibly adjust the altitude, the length of the fuse can be adjusted to control the explosion, enabling the projectile to detonate at altitudes between 100m and 350m. This method is widely applicable and highly controllable.

[0029] If this invention is applied to fireworks displays, it is necessary to fill the explosive charge with an effect charge, determine the orientation of the effect charge, and ensure that the projectile is uniformly oriented when it is loaded into the launch tube, so as to achieve directional ignition of the effect charge.
