NASA Model Wing Lights Up During First Pressure Sensitive Paint Tests

Automatically curated summary from NASA.

Researchers at NASA’s Langley Research Center conducted a first-of-its-kind wind tunnel test using unsteady Pressure Sensitive Paint on a Benchmark Supercritical Wing model. Tested inside the Transonic Dynamics Tunnel, the specialized coating glowed pink-purple under ultraviolet light, varying in brightness based on airflow pressure. High-speed cameras recorded these changes to enhance computer modeling for future aircraft designs. This milestone marked the technique's initial application on a large-scale, freely moving model within a low-oxygen environment, laying groundwork for testing flexible, adaptive aircraft models.

Context and limitations

The testing involved a generic benchmark wing model rather than a specific production aircraft, and practical implementation in flexible aircraft designs remains an ongoing research objective.
