Abstract
View Video Presentation: https://doi.org/10.2514/6.2022-3894.vid As part of an aircraft fatigue assessment program, the rotor loads of a tandem-rotor helicopter are deduced via flight test measurements. During in-flight maneuvers, accelerations and angular displacements of the rotor blades were measured. After correcting the measurements for installation errors, the experimental data and the blade mass properties were used in the rotor blade equations of motion, in order to derive the hub loads. Aside from describing the experimental setup and data reduction, the development of the equations of motion of a fully articulated rotor blade and a solution approach is outlined in this paper. The resulting hub loads deduced from the blade equations of motion are compared to several sources.

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
