Abstract

fetched live from OpenAlex

For modern aircraft with higher sweep angles flying at higher incidence, unsteady and burst vortex flow in the vicinity of the wing and downstream lifting surface lead to strong unsteady airloads and buffeting'. Thus, investigations were conducted in the Institute for Aerospace Research (lAR) Low Speed Wind Tunnel (LSWT)2 to study the buffet characteristics of the Standard Dynamics Model (SDM)3, a generic fighter aircraft configuration. Since the spectrum of the aerodynamic input load is reasonably flat over the frequency range of interest, the solution to the equation of the motion is easily solved in the frequency domain for a given aerodynamic loads and vice versa. Following Jones4 and Mabey3, it is suggested that 4mG(n) is the best parameter to use as a measure of buffet excitation due to flow separations and unsteadiness and to denote this as the buffet excitation parameter.

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.

Full frame distilled prediction

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.
