Abstract

According to the present invention, a bullet using an air wing is capable of generating a wing for increasing stability in the flight of a bullet through a generated flow of fluids by forcibly drawing in the flow of fluids generated from the front end of the bullet and discharging the introduced fluids to the outer circumference surface of one side of the middle or lower part of the bullet. According to the present invention, since fluids flowing from the outer circumference surface of the front end of a shot bullet are made to fly by forming an air wing at a predetermined angle on the outer circumference of a boat tail part or middle part, bullets with excellent quality and performance, which can achieve both safety and economic feasibility better than an existing method of applying flight stability by forming physical air, can be produced in large quantities.

Description

A projectile using a air-wing.

The present invention relates to a bullet using an air wing,

More specifically, air wings are formed on the outer circumferential side of the middle or rear end (boat tail) by introducing fluid into the outer circumferential side of the tip of the bullet, thereby increasing flight stability, extending the range, and increasing the breaking force. It relates to a bullet using.

Conventionally, by utilizing a physical wing of a mechanism that extends a built-in wing for the purpose of removing vortices formed at the rear or a built-in wing for stabilization of flight at the moment when the gun (pore) exits from the rear surface. It uses a method to increase accuracy by firing.

The above bullets are not economically efficient in making wings, and there are restrictions on their use. Due to this, there are inherent risks in use, and there is a large economic loss due to expensive operation.

In particular, there is a difficulty in implementing this in a smaller caliber than a larger caliber, which is not applicable.

The present invention forms a conventional physical wing by allowing the fluid flowing from the outer circumference of the outer surface of the front end of the projected bullet to fly by forming an air wing at a certain angle of the outer circumference of the middle or rear end (boat tail). It is a method that realizes both safety and economics rather than a method of imparting flight stability. By using this, it can be applied to both small-diameter and large-caliber bullets, so it can be applied to all bullets fired from guns.
