Development of a morphing wing extrados made of composite materials and actuated by shape memory alloys
Bibliographic record
Abstract
This article focuses on the development of a shape morphing composite skin representing a wing extrados. The objective is to design and manufacture a skin capable of changing its geometry in order to improve its aerodynamic efficiency. One geometry is considered to be the nominal geometry and a deformed geometry is identified. It is obtained upon application of a displacement at the aftmost boundary of the active portion of the wing profile. The displacement is imposed on the skin by shape memory alloy wires. These actuators are combined with a self-locking transmission mechanism that maintains the deformed geometry without any further energy consumption. The lay-up of the composite skin is optimised such that the deformed profile approaches the desired geometry as closely as possible. This lay-up selection routine is done through an ANSYS Parametric Design Language sub-routine. The finite element model is validated experimentally by conducting mechanical testing on the composite skin.

How this classification was reachedexpand
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.
