← ScienceWhich risk increases when a subsonic aircraft exceeds its critical Reynolds number?
A)Laminar flow transforms to turbulence✓
B)Compressibility effects cause sonic boom
C)Parasitic drag reduces lift force
D)Induced drag creates vortex shedding
💡 Explanation
When the Reynolds number is exceeded, laminar flow transitions due to boundary layer instability; therefore, the risk of turbulence increases substantially because increased energy dissipation occurs, rather than the other factors happening primarily in supersonic conditions.
