Research Institution

Technology Assessment & Transfer, Inc. (TA&T) and their collaborators propose a 3D printed, multilayer magnetic shielding disk to protect sensitive electronics in electromagnetic railgun hypervelocity projectiles. Topology optimization coupled with multiphysics finite element analysis modeling will be employed to optimize the thickness, arrangement, and internal geometry of various metallic and ceramic layers. These models will be used to converge on designs that minimize weight and volume while maximizing electromagnetic shielding effectiveness. 3D printing of the ceramic layer and subsequent mechanical testing will be done in Phase I. Magnetic shielding effectiveness will be evaluated in the Phase I Option period, and 3D printing of both the ceramic and metallic layers will be conducted in Phase II. Phase II will involve optimizing models and scaling-up to 3D printing of 3-5 inch diameter magnetic shielding disks.
