← TechnologyWhich mechanism diminishes aircraft wing lift when encountering turbulent air?
A)Dynamic stall angle oscillation✓
B)Boundary layer laminar separation
C)Chordwise pressure gradient equalization
D)Spanwise vortex shedding suppression
💡 Explanation
Dynamic stall angle oscillation reduces lift because rapid changes in the angle of attack cause the airflow to separate from the wing's surface, thus reducing pressure differential. Therefore, lift is diminished, rather than other outcomes linked to attached flow.
