← TechnologyWhich consequence arises in aircraft wing design when exceeding the critical Mach number?
A)Wave drag significantly increases✓
B)Lift generation becomes more efficient
C)Span-wise flow fully laminarizes
D)Boundary layer becomes more attached
💡 Explanation
Exceeding critical Mach number initiates the formation of shockwaves on the aircraft wing due to compressibility effects because local airflow reaches sonic speeds initiating wave drag. Therefore, the drag drastically increases, rather than laminarizing or improving lift.
