Speed of sound at point one on the airfoil refers to the local speed at which pressure waves or sound waves propagate through the fluid at a specific location on or near an airfoil’s surface. In other words, it’s the speed at which disturbances in pressure, velocity, or density travel through the fluid near the airfoil.Â
