← ScienceWhich outcome occurs when subsonic airflow separates during flight?
A)Increased wave drag forms stall✓
B)Reduced skin friction lowers velocity
C)Pressure increases stabilize airflow
D)Laminar flow prevents induced drag
💡 Explanation
Increased wave drag leading to stall results because separation causes turbulent boundary layer at altitude during subsonic laminar flow disruption; therefore wave drag contributes to reduced lift rather than increased lift, because pressure stabilizes the stalled flow aloft.
