Regime
An aeroelastic boundary — a root of the characteristic quartic, quasi-steady
Every figure drawn under this hypothesis — 4 of them — with the essay each one belongs to and the generator that drew it.
4 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.
- The speed where the damping is exactly zero — structural frequencies 50 and 100 radians a second · lift-exact
- The speed where the damping is exactly zero — the same section — mu = 40, frequency ratio 0.5 · lift-exact
- The speed where the damping is exactly zero — the same section · lift-exact
- The speed where the damping is exactly zero — six frequency ratios at mu = 40 · lift-exact
