Abstract

fetched live from OpenAlex

A morphing aircraft adapts to different missions by changing the shape of its wing. With the wingspan change or chord length change, the wing skin will change, which requires the design of the variable wing covering to meet the morphing wing. The core of the variable stiff wing-covering design is splitting the wing surface. By solving the problem, the sliding morphing of the stiff skin is achieved. According to the characteristics of the wing surface, this paper gives two stiff wing-covering segmentation algorithms. First, based on the change of airfoil curve that happened before and after the chord length change, the horizontal noninterference segmentation and morphed method of rigid wing skin is proposed. The airfoil curve is divided into pieces, and the definition of the curve similarity evaluation criterion (that is, ) is presented. The horizontal rigid-surface morphing is achieved, depending on the noninterference folding morphing and the airfoil curve length difference. Second, according to the feature of the column side caused by stretching or shortening of the column, a vertical segmentation method (named “petalized”) of the stiff wing covering for the wingspan change is proposed. By means of the segmentation results of the original column side split through the hierarchical structure and the modular concept, the vertical rigid morphing is achieved. In the last step, two experiments validate the horizontal and vertical algorithms of segmentation and morphing, and they make an analysis of the algorithm complexity.

Not 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.
