← ScienceWhich outcome results from turbulent airflow across airplane wings?
A)Increased drag and reduced lift✓
B)Optimized laminar boundary layer suction
C)Higher stall angle, improved maneuverability
D)Decreased skin friction, sonic boom delay
💡 Explanation
Turbulent airflow increases drag and reduces lift because momentum transfer disrupts the pressure distribution, leading to flow separation rather than a smooth transition; therefore, drag increases, rather than lift enhancement caused by streamlined airflow.
