Regime
Set by the tip-speed and advance ratios — a rotor with blades rather than a disc
Every figure drawn under this hypothesis — 28 of them — with the essay each one belongs to and the generator that drew it.
28 figure placements state this regime. The strip along the foot of every figure names two things — the model that produced it and the regime it holds in — and this listing is read back out of the finished drawing rather than from what produced it.
- A blade that flies through what it shed — μ = 0.4 — forward flight, rigid blades, a lift coefficient capped at 1.2 · circulation-ledger
- A calculation with no memory in it — the swept area is the stroke amplitude times the wing length squared — an ideal blade-element disc · the-history-a-picture-leaves-out
