A rotatable electromagnetic railgun shell

Abstract

The invention discloses a rotary electromagnetic rail gun shell. A thread is arranged on the outer surface of the back part of a fuse; a groove is formed in the front end of a shell body; an internal thread is arranged in the groove; the fuse and the shell body are connected through the thread; a T-shaped groove is formed in the outer wall of the shell body; a T-shaped plate is inserted in the T-shaped groove on the outer wall of the shell body, and is fixed on the inner wall of an inner plate of a rotary power shell; the rotary power shell coats the shell body; the inner plate and an outer plate of the rotary power shell are cylindrical shells opened at two ends; the inner plate is positioned in the outer plate; a blade is arranged between the inner plate and the outer plate; a thread hole is formed in the back end of the shell body; the back end of the shell body is near one side of an insulation layer; a through hole is formed in the middle part of the insulation layer; the other side of the insulation layer is near one end of an armature; a screw penetrates through a through hole in the middle part of the armature and the through hole in the middle part of the insulation layer from right in sequence; a thread is arranged at one end of the screw; one end of the screw is inserted in a thread hole at the back end of the shell body; and the screw is in threaded connection with the shell body. The rotary electromagnetic rail gun shell is stable in shell moving direction, high in shooting accuracy, farther in range and suitable for remote and precise military operation of an electromagnetic rail gun.

Description

technical field [0001] The invention relates to the field of electromagnetic emission. Background technique [0002] The electromagnetic railgun is a lethal weapon that uses electromagnetic launch technology to convert electromagnetic energy into kinetic energy of projectiles. Compared with traditional artillery, the electromagnetic force is stronger than the gunpowder gas pressure, and the action time is longer, which greatly improves the export kinetic energy and firing range of the shell. If the electromagnetic railgun is in a parallel flight state after being ejected from the chamber, a large torque will be generated under the action of air resistance and its own gravity, which will easily change the flight state of the shell, causing problems such as swinging or flipping of the shell, reducing the impact of the shell. flight stability and shooting accuracy. In addition, since the magnitude of air resistance is generally proportional to the square of the speed, the ele...

AI Technical Summary

Problems solved by technology

If the electromagnetic railgun is in a parallel flight state after being ejected from the chamber, a large torque will be generated under the action of air resistance and its own gravity, which will easily change the flight state of the shell, causing problems such as swinging or flipping of the shell, reducing the impact of the shell. flight stability and shooting accuracy

In addition, since the air resistance is generally proportional to the square of the speed, the electromagnetic gun shells will suffer from greater air resistance under the condition of higher exit speed, which will seriously affect its range.
