RotorBench-Aero v0.1 · 2026Q2

The neutral benchmark for rotating-machinery ML.

A standardised, contamination-resistant benchmark for AI surrogate models that design and simulate rotors. The MLPerf of rotating machinery.

§01Why a domain benchmark

Generic ML benchmarks measure things like image classification accuracy. They tell you nothing about whether a surrogate predicts Cl/Cd on a wind-blade section to the tolerance a procurement engineer needs.

Comparotor measures the things rotor designers actually use surrogates for — and rotates the test set quarterly so vendors cannot pre-train on it.

Domain-specific scoringMAE on Cl, Cd, Cm; L/D rank correlation; OOD generalisation; inference latency.
Contamination resistance50-airfoil quarterly rotation. The test set didn't exist when you trained.

§02Who it's for

Vendors

Physics-ML startups

Your customers ask 'how do we know your model works?' — point them at a third-party score that's comparable across vendors.

Buyers

A&D and energy OEMs

Cut through marketing claims when procuring ML surrogates. Get signed reports your simulation team will trust.

Academia
