How many vortex generators are on each wing?

• A. 6
• B. 8
• C. 12
• D. 14

Answer: (C)

Vortex generators energize the boundary layer by creating tiny, stable vortices that mix higher-energy air from above with the slower air near the wing surface. This helps keep the flow attached at higher angles of attack and with flaps extended, preserving lift and control effectiveness when the wing is most prone to separation. On the Citation Longitude, there are twelve vortex generators on each wing. Their placement along the leading edge is tuned to cover the critical span where separation would occur under high-lift conditions. This specific count provides enough energy input across the wing to delay stall and maintain aileron effectiveness, while avoiding unnecessary drag and weight.
