## What's in it

* 12,000 CFD runs across 2,400 distinct fixed-wing UAS planform geometries (Latin Hypercube sampled) at 5 angles of attack each
* 10,000 runs completed in 32.2 hours; 11,950 of 12,000 completed overall
* Fixed cruise conditions: Mach 0.21, ISA standard day at 30,000 ft
* Per-run outputs: aerodynamic scalars (C\_L, C\_D, L/D, moments), surface pressure/force distributions, and full 3D flow fields (instantaneous + time-averaged)
* \~1.1 GB per run, \~13-14 TB total
* Simulated on CoreWeave's GPU cloud infrastructure

## Intended use

Design space characterization and surrogate-model / MDO (multidisciplinary design optimization) training over parametric planform geometry.
