← ScienceWhich consequence results when turbulence develops within supersonic airflow around an aircraft wing?
A)Reduced lift and increased drag✓
B)Increased lift and reduced drag
C)Decreased skin friction coefficient
D)Enhanced laminar boundary layer stability
💡 Explanation
Turbulence induces momentum transfer, a mechanism which increases the thickness of the boundary layer. This leads to increased form drag and a reduction in the pressure differential generating lift because the pressure recovery is worse than for laminar flow; therefore lift decreases and drag increases.
