← ScienceWhich effect increases when exceeding the Reynolds number threshold in aircraft wing design?
A)Increase of lift coefficient instability✓
B)Increase of laminar boundary layer
C)Decrease in parasite drag profile
D)Increased damping from airflow attachment
💡 Explanation
Exceeding the Reynolds number leads to a shift to turbulent flow, causing increased lift coefficient instability because of boundary layer separation due to increased momentum transfer; therefore A rather than laminar flow, with smoother airflow conditions.
