NASA uses unsteady PSP high tech paint for rocket pressure testing

0

The video is a visualization of the full-coverage measurements of unsteady pressure affecting a rocket, taken during simulated launch in a wind tunnel test. Both aircraft and spacecraft must be designed to withstand these dynamic forces, called buffeting, or risk being shaken to pieces. The pressure data is visualized as colors (red: higher-than-average pressure; blue: lower-than-average pressure), and represent the moments before the rocket reaches supersonic speeds.
