Scaling method on electromagnetic railgun

In order to conduct experimental study effectively, the scaling method used in a small or medium caliber railgun launcher was analyzed and improved. In consideration of the feasibility of the experimental conditions, studies on the electromagnetic field and loading capacity were conducted under the condition that the material properties were constant. In addition, related simulations were carried out to prove the scaling model. Results indicate that there are various scaling methods. In a large diameter rail launcher with relatively low conductivity, the physical fields can match the model launcher which has higher conductivity.
