ELECTROMAGNETIC AND STRUCTURAL-ANALYSES OF ELECTRIC GUN AND INTEGRATED LAUNCH PACKAGE SYSTEMS

This publication describes electromagnetic and structural analyses of electric gun and integrated launch packages. Models presented were dev eloped for the Sabot Launched Electric Gun Kinetic Energy projectile ( SLEKE) program and the Cannon Caliber Electromagnetic Launcher (CCEML) program. Analyses were three-dimensional, transient and coupled with thermal calculations including dynamic material properties. In the SLE KE analysis section we focus on electromagnetic and structural perform ance of integrated launch packages. SLEKE analyses have been validated by successful launch of test articles at maximum design levels. CCEML launch package and barrel performance has been studied in detail whic h benefits from experience gained in the SLEKE program. CCEML analyses presented focus on augmented launcher performance.
