ROSS 2.3 undamped
Foil 1e6–5e6 crosses a critical before 80k. First pair 26.4k at 1e6. Need k ≳ 5e7 for 80k. 1st pair 26.4 krpm at k=1e6, ~80 krpm at 1e7, AMB needs ≥5e7. J2 foil can ends Z=71.00, disk 72–76.
CoolProp mean-line P/T/h/C vs station, Span-Wagner CO2. NOT Fluent, NOT viscous, NOT the 20k spin.
CoolProp HEOS CO2 path, stations 1→5, 25 MPa / 650 C → PR 1.8. A table walk, NOT a measured cycle.
Velocity triangles, radial blades, Cθ2=U2. 80k labels, NOT the 20k foil spin. C3=120 labeled; exit swirl NOT signed.
Loss register, sum 17.3 pts, η_ts if sum 0.827. A budget, NOT a CFD result. 0.75 stays a label. Futral tip would be 7.6 pts — not used.
ROSS 2.3 undamped critical speed vs journal k, Z=72 cut, no catcher. Foil 1e6–5e6 crosses a critical before 80k. Undamped map, NOT a measured response; 80k line unsigned.
