Description

Drone-based projectiles for destroying building windows

[0001] The present invention relates to a drone-mounted projectile for destroying building windows, which is launched from a launcher mounted on a drone and can destroy building windows.

[0002] Unmanned aerial vehicles (hereinafter referred to as "drones") capable of flight, equipped with rotating propeller-like wings, have been proposed in various forms. These drones are being modified with various additional functions. For example, a drone equipped with additional functions for fire suppression has been proposed.

[0003] Meanwhile, when providing a fire suppression function or rescue function for people inside a building through a drone, fire suppression or rescue may be hindered by the glass windows of the building.

[0004] Therefore, before putting out a fire or rescuing people, it is necessary to first perform the task of destroying the building's windows using a drone.

[0005] After a building's windows are destroyed, the same drone or another drone can release fire extinguishing agents, enabling easy access to high-rise fire scenes where fire trucks have difficulty approaching, thereby providing fire suppression capabilities.

[0006] Republic of Korea Patent No. 10-2394457, “Aircraft equipped with a launching device” (registered on June 2, 2022), describes such a drone.

[0007] However, existing technologies have not yet conducted proper research on how to design projectiles launched from drones to destroy building windows.

[0008] The present invention has been devised to solve the problems of the prior art as described above, and aims to provide a drone projectile for destroying building windows, which is launched by compressed air from a launcher mounted on a drone and can efficiently destroy building windows.

[0009] In order to solve the above problem, the present invention is characterized by including a breaking unit including a breaking unit body in the shape of a rod extending in the longitudinal direction and a tip portion that is sharply protruded forward from the breaking unit body; a rotation guide body in the shape of a rod formed to surround the longitudinal central portion and the longitudinal rear end portion of the breaking unit body; a sectional area reducing portion in the shape of a frustocone that is formed to protrude forward from the rotation guide body in a shape with a decreasing cross-sectional area and surround the longitudinal front end portion of the breaking unit body; and a rotation guide portion including a plurality of spiral grooves formed to extend along the outer circumferential surface of the rotation guide body over the entire length of the rotation guide body so as to apply a rotational force to the rotation guide body while compressed air is discharged, the rotation guide portion being made of a material having a hardness and a specific gravity lower than those of the breaking unit.

[0010] In the above, it is preferable that a plurality of anti-rotation grooves are formed in the body of the breaking unit, and that an anti-rotation protrusion is formed in the rotation inducing unit to be coupled to the anti-rotation grooves.

[0011] As described above, the present invention provides a drone projectile for destroying building windows, which is launched by compressed air from a drone launcher and has a breaking section having a tip and a rotation guide section having a spiral groove formed therein that receives rotational force as compressed air is discharged when the drone projectile is launched by compressed air, thereby allowing the drone projectile to fly while rotating and improving the accuracy and destructive power of the drone projectile.

[0017] Below, with reference to the attached drawings, embodiments of the present invention are described in detail so that those skilled in the art can easily implement them. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, irrelevant parts have been omitted for clarity of description, and similar reference numerals have been assigned to similar parts throughout the specification.

[0018] Throughout the specification, whenever a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise stated.

[0019] FIG. 1 is a front view of a drone projectile for destroying a building window according to one embodiment of the present invention, FIG. 2 is a cross-sectional view of FIG. 1, FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, FIG. 4 is a cross-sectional view taken along line BB of FIG. 2, and FIG. 5 is a cross-sectional view showing the destruction part and the rotation induction part of FIG. 1 separated.

[0020] This drone launcher is launched by a launcher provided on the drone.

[0021] There are already many different technologies known for launching drones and air gun types.

[0022] In general, an air gun is a firearm that is fired by the power of compressed air (or compressed gas).

[0023] Air guns can be classified into spring type, liquefied carbon dioxide type, and compressed air type according to their firing principles, and compressed air type can be further classified into PCP (Pre-Charged Pneumatic) type and Single / Multi-Stroke Pneumatic type.

[0024] This embodiment assumes a launching device in the form of an air gun that provides a compressed air cylinder for storing compressed air in a drone and launches a drone projectile using the compressed air ejected from the cylinder, but is not limited thereto.

[0025] Describes the characteristics that a projectile fired from an air gun-type launcher mounted on a drone must have.

[0026] The drone-mounted projectiles fired from the launcher must have sufficient destructive power to destroy building windows (especially tempered glass windows), and must have a high accuracy rate even in high wind speeds to destroy the windows of high-rise buildings.

[0027] In addition, for stable flight, drones must fly a certain distance away from high-rise buildings, as it is difficult to get close to the windows of high-rise buildings due to wind and fire.

[0028] In other words, drone projectiles must be designed to have high destructive power and high hit rate even when launched from a considerable distance in high wind speeds.

[0029] Meanwhile, since the purpose is to destroy building windows, the compressed air stored in the compressed air bomb of the launcher is sufficient to have the capacity for several launches.

[0030] This drone projectile (100) is composed of a blasting part (110) with high hardness and specific gravity and a rotation induction part (120) with low hardness and specific gravity.

[0031] The breaking part (110) includes a breaking part body (111) and a tip (112).

[0032] The body of the breaking part (111) is formed in the shape of a rod extending in the longitudinal direction, and a plurality of anti-rotation grooves (111a) are formed on the body of the breaking part (111).

[0033] In this embodiment, the anti-rotation groove (111a) is formed in the longitudinal front end of the body (111) of the breaking unit, and the anti-rotation groove (111a) is in the shape of a groove extending in the longitudinal direction.

[0034] A tip (112) is formed to protrude sharply forward from the body of the destruction part (111).

[0035] The tip (112) is a part that is designed to come into direct contact with the building's glass window and destroy the building's glass window.

[0036] Therefore, the breaking part (110) is made of a material with high hardness and specific gravity.

[0037] For example, as a material for the breaking section (110), a metal material whose hardness has been improved by heat treatment can be used, but is not limited thereto.

[0038] The tip (112) of the breaking unit (110) has a sharp structure, so that when it comes into contact with a building glass window, the impact is concentrated in the form of a point with a very small area, so that the building glass window can be easily destroyed.

[0039] A rotation induction part (120) is provided to surround the body (111) of the breaking part (110).

[0040] The rotation induction part (120) is made of a lightweight material with lower hardness and specific gravity than the breaking part (110).

[0041] For example, as a material for the rotation induction unit (120), a metal material such as aluminum or duralumin or a synthetic resin material can be used, but is not limited thereto.

[0042] Since the rotation induction part (120) has lower hardness and specific gravity than the destruction part (110), it can prevent damage to the launcher (the part corresponding to the barrel of an air gun) even when it comes into contact with the launcher.

[0043] The rotation induction unit (120) includes a rotation induction unit body (121) and a cross-sectional area reduction unit (122).

[0044] The rotating induction body (121) is a rod-shaped body formed to surround the longitudinal center and longitudinal rear end of the breaking body (111).

[0045] A plurality of spiral grooves (121a) are formed along the outer surface of the rotation induction body (121) and extend over the entire length of the rotation induction body (121).

[0046] The spiral groove (121a) is formed so that when compressed air is ejected, some of the compressed air is discharged along the spiral groove (121a) and rotational force is applied to the rotation induction unit (120).

[0047] A groove (121b) for receiving compressed air is formed at the rear of the rotating induction body (121).

[0048] The compressed air receiving groove (121b) is formed so that the force of the rotation induction part (120) being fired forward by the pressure of the compressed air is maximized.

[0049] The cross-sectional area reduction portion (122) is formed to protrude forward from the rotation induction portion body (121) in a form in which the cross-sectional area decreases, and is formed to surround the longitudinal shear portion of the breaking portion body (111).

[0050] In this embodiment, the cross-sectional area reduction portion (122) has a truncated cone shape. This cross-sectional area reduction portion (122) is intended to minimize air resistance when launching a drone projectile.

[0051] In this embodiment, an anti-rotation protrusion (122a) is formed at the front end of the cross-sectional area reduction portion (122) and is inserted into and joined to an anti-rotation groove (111a).

[0052] By combining the anti-rotation protrusion (122a) and the anti-rotation groove (111a), the rotation of the rotation inducing part (120) can be directly transmitted to the breaking part (110), and thus, as the rotation inducing part (120) rotates, the breaking part (110) also rotates together.

[0053] As described above, the drone projectile of the present invention is configured by combining a blasting unit (110) and a rotation induction unit (120), and by inducing rotation of the drone projectile through the rotation induction unit (120), the accuracy and destructive power of the drone projectile can be improved.

[0054] In addition, since the launcher only comes into contact with the rotation guide unit (120), it is prevented from being damaged even after long-term use.

[0055] The above description of the present invention is for illustrative purposes only, and a person having ordinary skill in the art to which the present invention pertains can implement the present invention in various forms.

[0056] Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined manner.

[0057] The scope of the present invention is defined by the claims set forth below.

[0058] The present invention can be used as a drone projectile for destroying building windows, which can be launched from a launcher mounted on a drone and destroy building windows.
