The Time-Resolved Elastodynamic Discrimination (TRUE-D) Laboratory Directed Research & Development project is focused on improving safety systems for new nuclear weapons, with the goal of making them more cost-effective and faster to develop. One significant outcome was the creation of new materials and design insights that help control signals and power transmission for weapon operation and offers a reliable alternative to traditional, more complex mechanical safety systems. The TRUE-D flight hardware was tested on the SkyFox flight demonstrator, showing promising results that could shape the future of nuclear programs.
Through NNSA’s Weapon Technology Program, TRUE-D will be integrated into advanced systems that enhance national security by ensuring nuclear weapons are safer and more efficient to operate.
Skyfox: Revolutionizing hypersonic flight testing
Sandia developed SkyFox, a low-cost, modular, and scalable guided flight test platform designed to accelerate experimentation and technology maturation in hypersonic boost glide vehicles. Leveraging Sandia’s expertise in hypersonics and advanced manufacturing techniques like metallic 3D printing, SkyFox features a Core system with commercial-off-the-shelf avionics and advanced control software housed in a thermally and mechanically isolated package, enabling flexible vehicle configurations.
Initial tests involve small rocket launches with parachute recovery, allowing vehicle reuse to significantly reduce costs and turnaround times. This innovative approach empowers rapid iteration and technology evolution, addressing traditional barriers of high cost and infrequent launches in hypersonic development.
