Electromagnetic and Structural Analyses of Electric Gun and Integrated Launch Package Systems
MetadataShow full item record
The authors describe electromagnetic and structural analyses of electric gun and integrated launch packages. Models presented were developed 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 SLEKE analysis section, the authors focus on the electromagnetic and structural performance of integrated launch packages. SLEKE analyses have been validated by the successful launch of test articles at maximum design levels. CCEML launch package and barrel performance has been studied in detail which benefits from experience gained in the SLEKE program. CCEML analyses presented focus on augmented launcher performance.
