Linear Transformer Drivers for Propulsion and Power, Year 2

Completed TRL 4 (started at 4, targeting 4)

Description

Explore a variant of the linear transformer driver (LTD) concept being developed by Sandia Laboratories and University of Michigan, with the following differences: (1) Use smaller capacitors, for smaller bricks; (2) Assemble into much smaller cavities; (3) Add layers to the stack, introducing the super-cavity and super-stack. The rationale for this approach is to maintain as much of the LTD at lower voltage levels as possible, to eliminate the need for submerging components in oil or other arc retarding media, and to reduce weight. Also allows spreading components out as much as packing efficiency allows, to dissipate thermal energy. Efforts in Year 1 was focused on demonstration of LTD cavity. Year 2 will focus on stack demonstration, including cavity optimization, simultaneous operation of multiple cavities, voltage addition, and testing in vacuum.

Benefits

Construct prototypes of revolutionary linear transformer driver technology for application to pulsed electric propulsion systems, or rail gun/launch assist systems. The eventual goal is to implode a fusion target.

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
