Abstract
An accelerated wear test program for an electromechanical actuator (EMA) was funded and conducted by Parker Aerospace and Lockheed Martin Aeronautics Company. Testing was performed at Dynamic Controls, Inc. The objective of the program was to identify failure pre-cursors that exhibited repeatable trends, and could be used to construct a remaining useful life algorithm with an identifiable confidence level. Selected mechanical components of the actuator were seeded with an abrasive contaminant to achieve accelerated wear. The desired goal was to achieve component wearout in approximately 24 hours, providing acceptable test times with pre-cursor signatures representative of normal wearout. The test facility and approach is described, along with failure criteria and test results. Although the scope of this effort was relatively limited, it revealed some potentially useful wear indicators, along with many areas of difficulty for which further effort is recommended.

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
