Thrust Enhanced by a Magnetic Laval Nozzle in an Applied-Field Magneto-Plasma-Dynamic Thruster
Bibliographic record
Abstract
The thrust imparted by an applied-field magneto-plasma-dynamic thruster is enhanced by superimposing a convergent-divergent magnetic field called a magnetic Laval nozzle. The thrust increases up to 6.9 N by increasing the magnetic field strength at the Laval nozzle throat. It is observed that the plasma flow velocity increases and the ion temperature simultaneously decreases downstream of the throat. A major component of the measured Lorentz force arising from the plasma-induced current is identified to be in the radial direction, while a significant increase in the plasma density is observed upstream of the nozzle. These results imply that the plasma pressure increases upstream of the magnetic Laval nozzle due to an inhibition of the plasma loss, which contributes to the increase of the thrust.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
