Technical Field

The invention relates to the field of electromagnetic cannons, in particular to a bullet for an electromagnetic cannon, which has a simple structure, small friction with a track and electric conduction through liquid.

Background

The principle of the electromagnetic cannon is that a conductive projectile is communicated with a positive rail and a negative rail, and the projectile is accelerated to slide on the rails due to electromagnetic induction force, so that the electromagnetic cannon obtains a great speed. However, this can cause problems, such as welding where the projectile contacts the rail, or even forcing the projectile to adhere to the rail due to welding. The currently widely adopted method is to use aluminum pellets, the melting point of aluminum is lower, and the contact point is easy to melt instantly, so that the friction force between the aluminum pellets and the rail becomes very small. However, aluminum shot also has disadvantages: 1. residual aluminum slag can be generated on the track; 2. the rail can be ablated; 3. consumes valuable instantaneous high-power electric energy; 4. due to the high temperature, the aluminum shot cannot be provided with electronic components for guidance.
