Flight Testing of Automated Rotor Track and Balance using Active Trim Tab and Pitch Control Rod Technologies
Bibliographic record
Abstract
An innovative prototype in-flight automated rotor track and balance (RTB) system using advanced algorithms to command active rotor blade trim tabs and pitch control rods was demonstrated in a full-scale UH-60M flight test conducted by the U.S. Army. The primary technical objective was to reduce main rotor one per revolution (1P or 1/Rev) vibrations and maintain them at or below vibration acceptance levels throughout the entire flight envelope and achieve this in the presence of blade anomalies that create rotor imbalances. A secondary objective was to minimize higher harmonic vibration at two per revolution (2P or 2/Rev) and three per revolution (3P or 3/Rev) frequencies, without negatively impacting 1P. The flight test demonstration showed the system successfully met the desired performance objectives with the necessary characteristics to operate safely under normal flight conditions.

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.
