NASA Paints Airplane Parts Pink ... But Not Why You Might Think

Special Pressure-Sensitive Material Helps In Wind Tunnel Testing

While it may bear an eerie resemblance to a teenager's blacklight posters in the 1970s, the pink paint on aircraft and aircraft parts being wind-tunnel tested by NASA is about more than just glowing in the dark.

The pink coating is a pressure-sensitive material that has has developed over the past 25 years, according to a report appearing on Digitaltrends.com. It is based on research focused on oxygen concentration and luminescence. Basically the higher the concentration of oxygen, the less the material glows.

So, as air passes over the surfaces of the test objects in the wind tunnel that are coated with the pressure-sensitive paint, scientists and engineers refine the aerodynamics of whatever they are testing.

The result is aircraft that are more fuel-efficient, produce less pollution, and are quieter than their predecessors, according to the report.
