Simulation and Performance Analysis of Modular Electromagnetic Launcher ‘RAFTAR’
摘要
Projectiles are accelerated using electromagnetic energy by the electromagnetic railgun. A FORTRAN program has been created in order to comprehend the device's mechanism of functioning and dependence on certain circuit parameters for performance. Studies have been done on the controlling force and the results of various retarding forces. Various heat loss methods are also taken into consideration. Both the contact force and dynamic resistance modeling have been done. The PP&EMD, BTDG (Vizag) Railgun facility ‘RAFTAR’ has attained 1 km/s velocity with an 8 g bullet with crowbar circuit configuration.
