This repository documents an open-source research project exploring counter-rotating gyroscopic propulsion with MHD interaction.
Could a closed system of counter-rotating fluid rotors, driven by MHD forces and controlled via gyroscopic precession, generate net linear thrust without mass ejection?
After theoretical analysis and peer review, we concluded:
-
Gyroscopes provide torque, not linear thrust. Precession changes orientation, but cannot produce net force in a closed system without external momentum exchange.
-
MHD forces in a sealed channel create internal pressure on walls, but the vector sum over a full rotation cancels out (∮ F·dθ = 0).
-
Conservation of momentum holds. Without ejecting mass or interacting with an external medium (air, plasma, field), no net thrust is possible.
-
Safety constraints are significant. Rotating ~40 kg at 300-600 RPM with contained liquid metal poses real risks if containment fails.
- No physically viable mechanism for net thrust in a closed system was identified.
- Building a prototype would not test new physics, only confirm classical mechanics.
- Risk/benefit ratio did not justify construction.

| Concept | Status | Notes |
|---|---|---|
| CMG-based stabilization | ✅ Proven | Gyroscopes for attitude control (used on ISS). Generate torque, not linear force. |
| CMG-based propulsion | ❌ Impossible | Violates conservation of momentum in a closed system. No external thrust. |
| Atmospheric MHD propulsion | Requires air ionization or mass flow (not a closed system). Low thrust-to-power ratio. | |
| Ion/electric propulsion | ✅ Proven | Vacuum thrust via mass ejection (xenon, etc.). Low thrust, high specific impulse. |
| Conventional rotors/propellers | ✅ Proven | Efficient, well-studied, scalable. Require atmosphere. |
| Flywheel energy storage | ✅ Proven | Kinetic energy storage for stabilization and peak smoothing. |
| Flywheel for direct thrust | ❌ Impossible | Closed system cannot produce linear thrust without external medium. |
Thanks to the engineering community for rigorous peer review, especially the critics who helped clarify the physics. Null results are still results.
