Transition armature technology project. Progress report No. 1, June 1--July 31, 1991
This first report covers the period June 1 to July 31, 1991. During this period we developed a detailed project plan which includes a balance between numerical simulation and experimental verification. A 2D MHD code (CALE) was adapted to a simple solid armature geometry. A numerical simulation verified the magnetic diffusion rate into the armature and rails was being calculated correctly. Furthermore, the distribution of temperature, current density in the rails and armature as well as the interface pressure between the armature and rails were calculated. A 2D boundary layer code (TKBLIMP) was adapted to simulate the conditions between a solid armature-rail interface as well as a sabot-rail interface. Preliminary results were obtained. Study of an augmented Quadra-Rail railgun concept was begun. Need for an armature test fixture, launcher test bed and suitable power supplies was established.
