Abstract
Helicopters are versatile tools for many applications but unfortunately create significant vibration and noise. Traditional passive and active approaches to suppress these vibrations are either effective only at specific frequencies or limited by electromechanical capabilities of smart actuators to overcome the severe aerodynamic conditions. The Smart Spring is a device that avoids these limitations by only altering the structural impedance properties of the blade root. It is desired to implement a numerical tool to analyze the effectiveness of the Smart Spring and to perform efficient parametric studies. In the paper, the Smart Spring is modeled in the SMARTROTOR aeroelastic/aeroacoustic helicopter code as part of the pitch link. It is verified that the Smart Spring is an effective tool for suppressing vibratory loads passing through the pitch link to the airframe. Copyright

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
