← ScienceWhich risk increases in aviation due to boundary layer transition?
A)Increased skin friction drag✓
B)Decreased lift coefficient
C)Propeller blade ice accumulation
D)Elevated fuel consumption at altitude
💡 Explanation
Increased skin friction drag results from transition to turbulence because the Reynolds number exceeds a critical value, therefore increasing drag. The larger turbulent boundary layer has more momentum exchange rather than remaining largely laminar.
