Abstract
Characteristics of a plasma actuator driven by direct-current discharge were studied experimentally in a supersonic flow. The discharge is generated between two small pin electrodes mounted on a Laval nozzle wall with a circle constant cross-sectional area in a Mach 3 flow. Current and voltage measurements indicated the generation of the discharge at low power consumption. It was confirmed that the wall static pressure increased beside each electrode and decreased just behind the anode for a 100 mA discharge. Furthermore, the increase in stagnation pressure and Mach number was observed close to the electrode surfaces. It was suggested that Joule heating of the flow and enthalpy elevation led to the change in the static and the stagnation pressure.

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 it
