Aeronautics researchers in the 1930s were struggling to determine the cause of a peculiar phenomenon - as an object approached the speed of sound, drag greatly increased and lift drastically reduced. In 1934, a young Langley researcher named John Stack figured out why by photographing a high-speed wind tunnel test of an airfoil. The photo captured the culprit - a shockwave. It was the first time a shockwave had ever been photographed on an airfoil. | |
