Effect of the Solenoid Dimensions Used in an Electromagnetic Launcher on the Height of Projection

Abstract

This paper describes the effect of the solenoid dimensions in an electromagnetic launcher on the height of projection. The height of projection is calculated by combining the circuit equation and the equation of motion. The magnetic force is carried by the finite element method. The calculation errors of the height of projection are respectively 5.5%. In conditions where the charging voltage V = 68 V and capacity C = 3.66 mF (input power W = 8.46 J), the height of projection of a solenoid with an outer radius r_o = 19 mm and length l = 22 mm reaches a maximum.
