Answer: Compressible
• Question 11
2.5 out of 2.5 points
As the airflow passes over the airfoil, its speed increases and, somewhere on the
surface of the airfoil, its speed reaches a maximum value of Mach 1 before
completely passing over the airfoil and returning to its freestream airspeed. The
airspeed that the aircraft is flying when this condition occurs is
