03 — Research

Independent aerospace research with technical notes alongside it.

Aerospace research anchors this work, from theoretical propulsion and launch environments to CFD and analytical methods. Notes on AI systems remain a separate technical stream.

Independent paperSpace propulsion

Bifrost Drive

A theoretical propulsion study examining whether energy collected by a Dyson swarm could power a directed laser system to accelerate a solar sail to relativistic velocities.

The work focuses on mathematical modeling and the mission implications of interstellar propulsion.

Secondary technical notes

Shorter notes on AI systems, OCR, verification, and local tooling sit alongside the primary aerospace research.
