Aerokinetic Heating on Projectiles in Hypersonic Flows
Bibliographic record
Abstract
In this paper, the flow field around and the heat-transfer characteristics of two different hypersonic projectiles are analyzed using computational fluid dynamics (CFD). Initially, complete flow fields are computed at a freestream Mach number of 7.0 for a 10° cone over a range of bluntness values at the tip. The computed heat-transfer results show the expected downward trend with increasing cone bluntness. Then the computations are extended to a high-kinetic-energy projectile with eight symmetrically placed fins. Tests are performed at a freestream Mach number of 5.4 using a non-contiguous grid. The CFD results capture the three-dimensional recirculation vortex upstream of the fin, and are used to relate the surface temperatures to the flow patterns. The numerical predictions agreed qualitatively with relevant data in the literature.

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.
