Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this work, optimized design and implementation of small sized portable capacitor driven pulse EMP system is demonstrated. The EMP system of single and double stages is mathematically modeled and simulated with finite element model to analyze relationships of; excitation coil current, exerted force on the projectile and relative projectile position. The simulation is used to identify optimized triggering instant for the second stage. An experimental portable single and double stage capacitor driven pulse EMP system hardware prototype is developed. The experimental setup is used for validation of simulation results, optimization of system design parameters and identifying optimized triggering instant of the second stage. For the given parameters of the developed experimental prototype, highest recorded velocity was 25 m/s; which is significantly higher than recently reported results for a fixed design of a capacitor driven coilgun. 96 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Dans ce travail, nous présentons la conception optimisée et la mise en oeuvre d'un système EMP à impulsions de petite taille, portable et alimenté par condensateur. Le système EMP à un et deux étages est modélisé mathématiquement et simulé à l'aide d'un modèle par éléments finis afin d'analyser les relations entre le courant de la bobine d'excitation, la force exercée sur le projectile et la position relative du projectile. La simulation est utilisée pour identifier l'instant de déclenchement optimisé pour le deuxième étage. Un prototype expérimental de système EMP à impulsions alimenté par condensateur, portable et à un ou deux étages, a été développé. Le dispositif expérimental est utilisé pour valider les résultats de la simulation, optimiser les paramètres de conception du système et identifier l'instant de déclenchement optimal du deuxième étage. Pour les paramètres donnés du prototype expérimental développé, la vitesse maximale enregistrée était de 25 m/s, ce qui est nettement supérieur aux résultats récemment rapportés pour une conception fixe de canon à bobine alimenté par condensateur. 84 pp. Französisch.…
