The transonic small-disturbance equation — the perturbation decides the type
Every figure drawn under this hypothesis — 2 of them — with the essay each one belongs to and the generator that drew it.
2 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 equation that changes type inside its own answer — M∞ = 0.9, sections of 10 and 6 per cent thickness · hot-gas
- The equation that changes type inside its own answer — γ = 1.4 — the boundaries are set by the perturbation, not by M∞ alone · hot-gas
