Abstract

The present invention relates to a bullet launcher, and more specifically, at the moment of supplying a spherical or streamlined bullet, rather than ammunition, to a rotating assembly that rotates at high speed by a drive motor into the loading chamber, a strong centrifugal force is generated by the high-speed rotation of the rotating assembly. This refers to a launch device that continuously fires a large amount of bullets with a powerful muzzle speed and high firing speed. This means that bullets are fired by a physical formula in which centrifugal force is generated in proportion to the square of the high rotation speed of the motor and the product of the bullet mass. This forms a bullet barrage to suppress attacks from small drones or AI autonomous swarm drones. Unlike regular firearms, which are fired with the explosive power of loaded ammunition, the gun is fired only with centrifugal force, so there is no explosion sound or recoil, so flames or overheating of the gun barrel do not occur. It can be fired continuously without reloading, and can be manufactured without additional development or new technology, so development and maintenance costs are low. It can be fired with only electricity and bullets, so launch costs are low.
In particular, when bullets with added lubricant are supplied to the loading chamber through a high-pressure hose, they are put into the bullet chamber of the rotating assembly, and bullets are loaded into several chambers and rotate, sequentially firing one bullet into the gun barrel per revolution from the launch port. It can be launched without reloading just by inserting a launcher, forming a barrage with hypersonic muzzle speed and a large amount of bullets, effectively suppressing attacks by swarm drones. It can replace expensive missiles or anti-aircraft guns, and Israel's Iron Dome Development is possible.

Description

Launch system using centrifugal force}

The present invention relates to a launch device using only the centrifugal force and rotational force of a high-speed rotating body. More specifically, the present invention relates to a spherical bullet that is injected into the rotating body only by centrifugal force due to the rotation radius and rotational speed of the rotating body instead of the explosion or recoil force of gunpowder. It is an invention about a launch device that fires fire through a gun barrel.

In general, devices or means of firing using centrifugal force and rotational force include the catapult used since ancient times, the rope sling used by David against Goliath, and hammer throwing in sports.

This generates a centrifugal force that is proportional to the square of the mass of the projectile and the rotation speed and inversely proportional to the radius of the rotating body, so that the rotating body rotates at a high speed and the projectile built into the rotating body can be launched by centrifugal force.

The problem to be solved by the present invention is that a rotating assembly rotated at high speed by a drive motor rotates inside the casing assembly, and spherical bullets that are introduced into the loading chamber through an external high-pressure hose are loaded into several loading chambers through the bullet chamber. It is a launch device that fires one bullet from the gear of the loading chamber launcher into the gun barrel at each rotation. It powerfully and continuously fires a large amount of bullets at a high muzzle speed by centrifugal force proportional to the mass of the projectile and the square of the rotation speed of the rotating body. there is.

In order to achieve this purpose, the present invention is a rotating drive shaft holder is mounted on a swing stand connected to a fixed stand containing a swing device fixed to the ground or chassis, and the rotation drive shaft on which the rotation assembly is fixed is fixed to the rotary drive shaft stand with a stand bearing. do.

The rotating assembly fixed to the rotating drive shaft is rotated by a drive motor inside the casing assembly fixed by the casing bearing, and the loading barrel mounted on the outside of the casing assembly receives spherical bullets through an external high-pressure hose and opens the bullet inlet. Bullets are introduced into the bullet chamber through centrifugal force, and in a state where they are loaded into the loading chamber by centrifugal force, one bullet is released at a time by the gear installed in the firing port of the loading chamber at each rotation, acting as a bearing between the inner circumferential surfaces of the casing assembly, and then being thrown into the firing port of the casing assembly. As a result, bullets are fired one at a time through the gun barrel by centrifugal force, and in order to minimize collision with the inner wall of the gun barrel as the bullets escape, the angle of departure of the bullets and the angle of the gun barrel are matched at a certain level of rotational speed.

The swing stand is equipped with a powerful drive motor for driving the rotation assembly and a elevation angle motor for adjusting the elevation angle of the casing assembly to adjust the elevation angle of the casing assembly through gears and suppress the rotational movement of the casing assembly.

In particular, the rotating assembly must maintain an appropriate gap with the casing assembly at high speeds, minimize power loss due to friction, and be balanced with an accurate central axis to prevent shaking or vibration.

If a higher rotation speed of the rotation assembly is required, a motor with high horsepower can be used, or motors can be installed on both sides and a separate increase gear can be used.

The bullets used can be of various calibers and weights depending on the caliber of the loading chamber of the rotating assembly, and the number of bullets fired per minute and the muzzle firing rate are proportional to the number of loading chambers, the rotational speed of the rotating assembly, and the size of the radius of the rotating body. Therefore, it is possible to implement various bullet calibers, number of bullets fired per minute, and range depending on the purpose.

The centrifugal force, which represents the muzzle speed, is proportional to the mass of the projectile bullet and the rotation speed square of the rotating body, so the launch speed and muzzle speed can be maximized, and the elevation and traverse angle adjustment devices and radars used in existing anti-aircraft guns can be used. It can be equipped with detection, tracking and aiming devices.

As described above, the present invention relates to a launch device that can continuously fire a large amount of bullets at a high muzzle speed without reloading.

The launch device using centrifugal force according to the present invention is a launch device to defend against attacks by drones, which are emerging as many threats in modern and future battlefields. In particular, it provides a means to effectively respond to attacks by AI autonomous swarm drones, which are developing. I can provide it.

In order to respond to this, there are limits to targeting and suppressing individual drones with lasers, anti-aircraft guns, frequency jamming, etc., so it is most effective to suppress drones by forming a barrage with a large amount of bullets, and the rotation speed of the rotating body and the loading room are limited. Since the number of bullets fired per minute is determined by the number of, it is possible to suppress drones by firing more bullets and faster muzzle speed than existing anti-aircraft guns.

If you substitute the physical formula, centrifugal force is the square of the rotational speed of the rotating body multiplied by the mass of the projectile and divided by the radius of the rotating body. Since centrifugal force increases in proportion to the square of the rotating speed, it is necessary to use accelerator gears in high-speed motors and rotate them. The centrifugal force can be maximized by maximizing the overall radius.

In order for the launcher to continuously fire and start and stop firing without reloading bullets, bullets with lubricant added from the outside are supplied and stopped using a high-pressure hose, so that firing can be done without reloading, and gunpowder is not used, so there is no explosion sound or flame. There is no problem with overheating of the gun barrel, and it is easy to manufacture using existing technology, so development and production costs are low.

In addition, there are fewer failures or malfunctions, easier maintenance, and it can be launched with only electric power and bullets, so it has the advantage of being cheaper to launch than using expensive anti-aircraft guns or missiles.

In addition, in order to maximize the kinetic energy of the bullet, it is possible to use a spherical bullet or a drop-shaped or streamlined bullet. It is easy to select the caliber and weight of the bullet, and the rotation speed and radius of rotation of the rotating body are expanded. It is a launch device that is more powerful than existing firepower, and can be said to be more effective in responding to high-speed small drones or hundreds of AI autonomous swarm drones than existing weapon systems such as missiles or anti-aircraft guns.

As an example, if the RPM of the rotating body is 6,000 RPM per minute with a high horsepower motor and speed gear, then 100 RPM per second, the rotating body diameter is 6M, the bullet diameter is 30mm, and the weight is 0.1kg, the physics of a launch device using centrifugal force Substituting the formula, the circumference is 18.8m when the diameter is 6M multiplied by the pi ratio, and at 100 RPM per second, the rotation speed is 1,885m per second, which is Mach 5.54.

The centrifugal force is calculated by multiplying the weight of the bullet (0.1 kg) by the square of the speed of 1,885 m and dividing by the radius of the rotating body to get 118 tons. The number of bullets fired per minute is 72,000 rounds per minute by multiplying by 6,000 RPM if the number of loading chambers in the rotating assembly is 12. In the case of a double barrel, it is possible to fire 144,000 bullets per minute at hypersonic speed of Mach 5.54, so it is possible to fire a large amount of bullets more powerfully than any existing launch weapon, forming a barrage against drones and suppressing them with an effective response. Development is possible with Israel's Iron Dome.
