Abstract
Small unmanned aerial vehicles (UAVs) come in many types, the most common being fixed-wing and rotorcraft. Most of these are powered by brushless dc motors driving fixed-pitch propellers. Since the thrusters are typically quite powerful, relative to the weight of the aircraft, the motion of these UAVs is usually dominated by the thruster dynamics. It therefore becomes particularly important to have a good model of the thruster, which can be assembled based on simple measurements of the system properties, rather than from exhaustive testing. This paper presents such a model. The governing equations are assembled by considering, in succession, the motor electrodynamics and the propeller aerodynamics. The results of the model are compared to experimental test results for a particular thruster assembly. Agreement between the two is excellent-with an error of 4.7% in thrust and 7.6% in torque under static conditions-thereby demonstrating the validity of the proposed approach.

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
