Abstract
Hybrid rockets offer numerous advantages over other types of rockets but tend to suffer from low combustion efficiency. Higher efficiency can be achieved by using passive devices in the combustion chamber that promote additional mixing of unreacted propellants. The current work examines a paraffin and nitrous oxide hybrid motor that uses a mixing device located downstream of the fuel grain to enhance combustion efficiency. The mixing device used in this work is a six-port baffle plate. Combustion efficiency, as measured by characteristic velocity, was found to increase by over 40% with the use of the passive mixing device. It was identified that certain high-mass-flux motor configurations resulted in unstable motor operation when the mixing device was present. Experimental results indicate that stable combustion occurs for oxidizer mass flux levels below . Exceeding this limit results in combustion oscillations in excess of 20% of the mean chamber pressure.

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
