Why Do Rockets 'Crackle'? How Supersonic Jets Make This Distinctive Sound.

Rockets are some of the loudest things that humans can experience, the Saturn V generated more power than entire US electric grid and converted about 1% of that into sound! There's a very distinctive crackle in the sound of a rocket which is a result of turbulence in the shear layer between the exhaust and the external atmosphere. I try to explain and visualize this using recordings of rocket launches and CFD simulations of jets. Thumbnail by Trevor Mahlmann Buy his images here: https://www.tmahlmann.com/photos/Rock...
