DEVELOPMENT OF A PARAFFIN/NITROUS OXIDE HYBRID ROCKET MOTOR FOR FLIGHT-BASED TESTING
Bibliographic record
Abstract
A 108 millimeter diameter hybrid motor has been developed using a liquefying paraffin-based fuel and nitrous oxide as the oxidizer. Multiple static test firings have been performed in addition to a successful sounding rocket flight. A number of practical lessons have been learned through the development process relating to injector configuration, regression rate and combustion efficiency. It is identified in the current work that further research is required in the liquefying fuel hybrid rocketry field in order to arrive at a collection of best practices for the design of efficient motors. Two primary concerns identified in this work are the structural properties of the paraffin-based fuel and efficient propellant mixing in the combustion chamber. Addressing these design considerations will be a major component in maturing liquefying hybrid fuels, such as paraffin wax, for use on larger scale vehicles intended for high-altitude or orbital missions.

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.
