Abstract
New design concepts for large flexible blades are needed to continue the trend towards ever larger turbines and continued economies of scale. Load alleviation based on building bend-twist coupling into the blades is an attractive concept because it can reduce the root bending moments and the fatigue damage in the blades with a negligible affect on the annual energy production. The challenges in quality control associated with fiber laminate lay-up processes present a risk associated with this concept. This study attempts to quantify this risk by evaluating the sensitivity of the blade’s elastic properties to various manufacturing defects. This study will look at the bend-twist coupling coefficient, weight, internal stress and tip deflection. The defects that will be considered are errors in position, size and thickness of the layers along with errors in the fiber angle.

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
