CS9-F — the V-bodies, and the wake they shed

Whole-aircraft RANS on the measured F article, 180k-class mesh, 36 m/s — the same instrument and tier as the family's other flow figures. Traces are released at the V-bodies' own heights and coloured by the induced vertical velocity — the aircraft's disturbance only — so clean air reads neutral at every angle and the wake is what shows. The V pylon-wings carry the engine pods at their original height; they are small lifting surfaces ahead of the tail, and above α≈9° they stall and shed.
The streak paths are the computed flow. The shimmer is stylistic — a steady solve carries no turbulence to animate — with amplitude tied to local disturbance.

The pins do not move. Where the CS9-A's neutral point walked forward through the CG, the F's holds station — margin +6.1% about the solo CG, never negative anywhere in the band. The F's own event is different: its V pylon-wings stall at α≈9° — measured three independent ways — and their wake crosses the inboard elevator. Elevator power was measured flat through α10; the wake is shown as what it is.
