Abstract

Many structural design issues associated with electromagnetic launch of projectiles will respond to the same techniques as used for conventional gun launch. The methods used to assess and manage the loads associated with the axial propulsive force (tapered sabots), with rapid propulsive rise time (dynamic finite-element analysis), and with transverse balloting loads (coupled projectile/gun models) are interpreted for high-velocity, electromagnetically accelerated projectiles. Some conclusions from these conventional interior ballistic technologies are offered for the designer
