Imagine trying to photograph wind. That’s similar to what NASA engineers dealt with during a recent effort to study how air moves around planes, rockets, and other kinds of aerospace vehicles. Air is invisible, but our understanding of how it flows is crucial for building better, safer aircraft. For 80 years, researchers used a technique […]

NASA Advances Pressure Sensitive Paint Research Capability
Many of us grew up using paint-by-number sets to create beautiful color pictures. For years now, NASA engineers studying aircraft and rocket designs in wind tunnels have flipped that childhood pastime, using computers to generate images from “numbers-by-paint” – pressure sensitive paint (PSP), that is. Now, advances in the use of high-speed cameras, supercomputers, and […]
