NASA tests pressure-sensitive paint on model wing in low‑oxygen wind tunnel
Based on · First reported
Sources
- NASA researchers at Langley Research Center in Hampton, Virginia, used pressure‑sensitive paint on a Benchmark Supercritical Wing model in the Transonic Dynamics Tunnel, a low‑oxygen wind tunnel, and captured the paint’s pink‑purple glow with high‑speed cameras.
- The test marked the first use of the paint on a large‑scale, freely moving model in such an environment, and the researchers anticipate that the technique could be applied to additional wind‑tunnel studies.
Why it matters
The ability to visualize pressure distribution on moving models in low‑oxygen conditions could improve aerodynamic testing for aircraft design.
