AbstractA state of the art technology suitable for facilitating the mass fabrication of metallic components used in high g gun-launched MEMS-based S&A devices is Bulk Metallic Glass (BMG). The emerging need for micro-scale S&A devices to complement the smart fuzing in modern munitions is jeopardized by high implementation cost of the metallic components able to survive the harsh gun-launch environment. The impact of cost reduction and/or cost avoidance on implementing critical munitions' designs actually starts with the S&A device. Tanner Research proposes to design and implement a mass fabrication production process for micro-scale bulk metallic glass (BMG) components with nano-scale tolerances. This production capability, when implemented in Phase II, will be similar to other MEMS-based processes implemented by Tanner, and used to support MEMS-based S&A device fabrication.
