NASA Tests New Pressure Sensitive Paint on Model Wing

Researchers at NASA's Langley Research Center have conducted groundbreaking tests using unsteady Pressure Sensitive Paint on a standard wind tunnel model, the Benchmark Supercritical Wing. This marks the first time this technique has been used on a large-scale, freely moving model in a low-oxygen environment.

The specialized paint glows pink-purple under ultraviolet light, with its brightness varying based on air pressure. High-speed cameras captured these changes, providing valuable data to improve computer modeling for future aircraft and rocket designs. The Benchmark Supercritical Wing serves as a universal model for refining these simulations.

This test integrated two key NASA tools and is a significant step towards wider adoption of pressure-sensitive paint in wind tunnel research. The successful application in the Transonic Dynamics Tunnel's unique environment paves the way for future tests on flexible aircraft models designed for improved flight efficiency.
