← ScienceWhich mechanism initiates stall in accelerating aircraft wings?
A)Adverse pressure gradient separation✓
B)Accelerated boundary layer compression
C)Induced lift exceeding design limits
D)Turbulence disrupting laminar airflow
💡 Explanation
The adverse pressure gradient separation initiates stall because a positive pressure gradient opposes flow near the wing surface lowering the Reynolds number, therefore detaching the boundary layer from the surface, rather than compression or lift or turbulence directly causing stall.
