NASA Tests Pressure-Sensitive Paint on Model Wing
Researchers at NASA’s Langley Research Center in Hampton, Virginia, conducted first-of-its-kind tests using unsteady pressure-sensitive paint in the Transonic Dynamics Tunnel. The illuminated paint was used to study how air flows around a standard wind-tunnel model, supporting development of capabilities for future aircraft technology design.
Researchers at NASA’s Langley Research Center in Hampton, Virginia, have conducted what NASA describes as first-of-its-kind tests using unsteady pressure-sensitive paint. The work took place in the center’s Transonic Dynamics Tunnel.
The test involved a standard wind-tunnel model wing coated with pressure-sensitive paint. NASA said the model lit up during the testing, allowing researchers to study how air flows around it.
The tests are part of efforts to develop new wind-tunnel capabilities for designing future aircraft technologies. The supplied NASA account does not provide additional details about the test date, the model’s specific design, or the results of the airflow measurements.
