critical Mach number, that is, the Mach number at which supersonic flow first develops locally on the airfoil, have drag rise Mach numbers significantly higher than the ewlier mACA four digit secriea airfoils.... The actual Critical Mach number varies from wing to wing. In general a thicker wing will have a In general a thicker wing will have a lower Critical Mach number, because a thicker wing accelerates the airflow to a faster speed than

The table also shows the critical Mach number for each angle of attack. If the onset flow exceeds this Mach number, supersonic flow will occur somewhere on the airfoil. This Mach number is also known as the "Critical Mach number".

exceeding the critical MACH number or MACH critical. (3) MACH critical is important to high- speed aerodynamics because it is the speed at which the flow of air over a specific airfoil design reaches MACH 1, but the most important effect is
