Homework Help: Shock wave

  1. Dec 3, 2005 #1
    What is the shock wave cone half-angle for a supersonic airplane flying at Mach 2.30?

    Would you use Mach=1/sin(theta) and then divide by 2 to get the half angle?

    So 2.30=1/sin(theta)=12.9 degrees

    [tex]sin\theta = \frac{1}{M}[/tex]

    So take the inverse sin of 1/M and you get the half angle. There is no need to divide by 2.
