Which flow alteration leads to increased drag around an aircraft wing when the Reynolds number increases past a defined threshold?

A)Decreasing boundary layer laminarization
B)Initiation of stall recovery protocols
C)Premature boundary layer transition
D)Increased adverse pressure gradient

💡 Explanation

Increased Reynolds number reduces viscous dampening and results in increased lift. This effect leads to premature boundary layer transition into turbulence because the flow is less stabilized, rather than stabilized; therefore, drag increases, not reduces.
