Abstract

fetched live from OpenAlex

View Video Presentation: https://doi.org/10.2514/6.2022-0801.vid Traditional airfoil optimization approaches often rely on intensive computational fluid dynamics (CFD) simulations and often needs high performance computing, which makes the optimization a computationally expensive process. In this work, we proposed a novel airfoil optimization framework that does not require any CFD simulations, the DockingNet — it is a neural network based model that docks an airfoil generator and an aerodynamic coefficient predictor. Instead of optimizing the pre-defined airfoil parameters, DockingNet searches the learned airfoil latent space via gradient ascent. Benefiting from the CFD free scheme, DockingNet reduces the optimization computation cost from hours to seconds.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
