VSV stage — vane proportion variants
The same mechanism (one-piece carrier ring, pressed bushings, spindle-mounted cambered vanes, lever + pin + bearing ball on a unison ring) rebuilt from DESIGN overrides. The shipped stage puts a 25 mm chord on an 81 mm pitch — solidity 0.3 where a real compressor stator runs 1.0–1.4 — so the vanes read as pegs.
Baseline (shipped)
as shipped — hub/tip 0.81, solidity 0.31
