The aerolog-scaling programme asks what a 1:N model of an electric cargo aircraft tells you about the full-size one. This step sent a Froude-scaled 1-cos vertical gust (gradient 5, 12.5 and 25 chords) through the four-state longitudinal model with NeuralFoil polars at each surface's own Reynolds number.
At 1:5, the uncorrected model's peak load-factor increment is within 2.0% of the full-size aircraft at all three gust lengths. Its peak pitch rate is 26.8 to 32.6% high and its peak pitch attitude about 20% high, which fits the 15% high short-period frequency found earlier. Of the 17 wings that restore the power ratio, none is within 10% on all three metrics.
Limits: no gust penetration lag, no alpha-dot term, rigid body, one reference aircraft, and the tail lift slope is itself uncertain by 20 to 35% against UIUC tunnel data. The UIUC host was blocked in this session, so the measured NACA 0012/0015 step stays open. Data: research/aerolog-scaling/experiments/gust_response/.
