Abstract

fetched live from OpenAlex

The modeling, the design, the numerical simulation and the experimental testing of the control system for a self-adaptive morphing wing model are here exposed. The study was performed during a multidisciplinary research project, involving industrial partners, a research institute and three academic entities. The developed control system is a multiloop one, being designed, simulated and tested in two major steps, correlated with the validation phases of the aerodynamic gains provided by the morphed wing model in terms of the laminar flow improvement over its upper surface. The two validation phases were suggestively called open loop, respectively closed loop; in the first phase the aerodynamic validation was made just by comparing the experimentally obtained results with the numerical optimization obtained ones, while in the second phase the morphing wing model was left free, to adapt itself based on the information related to the transition point position provided by some pressure sensors installed on its upper surface. The used wing model was a rectangular one, equipped with a composite made flexible upper surface, morphed along of two lines by using some shape memory alloy actuators. For the open loop phase a database with some optimized airfoils was generated and a smart controller based fuzzy logic was designed to control the position of the actuators in real time so that the desired optimized skin corresponding to the desired displacements to be obtained and maintained during the flight tests. The closed loop architecture was realized by using a real-time optimization algorithm, which included the actuators controller as inner loop. The algorithm was developed in order to generate real-time optimized airfoils starting from the information received from the pressure sensors and targeting the morphing wing main goal: the improvement of the laminar flow over the wing upper surface.

Teacher imitation

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.
