In his six short years at the NACA, German-born Max Munk brought some of Europe’s technical knowledge to the U.S.. His huge contribution was the Variable Density Tunnel (shown here, at right) – a revolutionary pressurized wind tunnel that could replicate flight conditions. Munk also revolutionized how to assess wing shapes, which led to better airplane design.
