Demo
    A rocket is launching vertically into the sky, leaving a trail of smoke behind. The launch site is situated in a valley with large, rocky hills in the background.
    Hypersonic turbulent spots were measured passing over the nose of a sounding rocket designed and launched by Sandia National Laboratories from a Hawaii test site in April 2019.
    Contour plot showing normalized pressure variations (p'/p∞) in a rectangular region, with color gradient from blue to red and contour lines. Axes are labeled in meters.
    The pressure footprint of one hypersonic turbulent spot at Mach 6. As turbulent air flows over a vehicle, thousands of such spots occur every second causing severe vibration.
