Freestream Velocity Normal in Hypersonic Flow Formulas

Freestream Velocity Normal is the velocity of air far upstream of an aerodynamic body, that is before the body has a chance to deflect, slow down or compress the air. And is denoted by U_∞. Freestream Velocity Normal is usually measured using the Meter per Second for Speed. Note that the value of Freestream Velocity Normal is always negative.
