Taschenbuch. Condizione: 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.…

Paperback. Condizione: new. Paperback. Dans ce travail, nous presentons la conception optimisee et la mise en oeuvre d'un systeme EMP a impulsions de petite taille, portable et alimente par condensateur. Le systeme EMP a un et deux etages est modelise mathematiquement et simule a l'aide d'un modele par elements finis afin d'analyser les relations entre le courant de la bobine d'excitation, la force exercee sur le projectile et la position relative du projectile. La simulation est utilisee pour identifier l'instant de declenchement optimise pour le deuxieme etage. Un prototype experimental de systeme EMP a impulsions alimente par condensateur, portable et a un ou deux etages, a ete developpe. Le dispositif experimental est utilise pour valider les resultats de la simulation, optimiser les parametres de conception du systeme et identifier l'instant de declenchement optimal du deuxieme etage. Pour les parametres donnes du prototype experimental developpe, la vitesse maximale enregistree etait de 25 m/s, ce qui est nettement superieur aux resultats recemment rapportes pour une conception fixe de canon a bobine alimente par condensateur.
