NASA Demonstrates Pressure‑Sensitive Paint on Large Wing Model in Transonic Tunnel
WHY IT MATTERS
The test validates a new diagnostic tool that can improve aircraft design accuracy, potentially leading to lighter, more fuel‑efficient planes and advancing NASA’s future flight technologies.
What happened
NASA’s Langley Research Center conducted the first large‑scale test of unsteady pressure‑sensitive paint (PSP) on the Benchmark Supercritical Wing inside the Transonic Dynamics Tunnel. The PSP coating glows pink‑purple under ultraviolet illumination, while high‑speed cameras capture pressure variations as the wing moves freely in a low‑oxygen environment.
This marks the first use of PSP on a freely moving, large model in such conditions, opening the door to future wind‑tunnel studies of flexible aircraft that bend and adapt during flight.
The resulting data will help refine computational models and support the design of more efficient aircraft technologies.
