NASA Advances Unsteady Pressure-Sensitive Paint Technology (uPSP) System
"NASA combines world class wind tunnels with supercomputing. The revolutionary unsteady pressure sensitive paint (uPSP) system is transforming aerosciences research—the fundamental field underlying all flight technology. This advanced technology system is transforming how we study airflow in wind tunnels, capturing high-resolution, real-time data on turbulent airflow and unsteady flow separation—critical for understanding how air moves over aircraft and spacecraft. NASA's Aerosciences Evaluation and Test Capabilities Portfolio Office (AETC) oversaw the development of this capability, with the expertise of the NASA Ames Unitary uPSP team. The uPSP system delivers results 10,000 times faster and 1,000 times more detailed than previous methods, providing research engineers with near-instantaneous feedback that was previously impossible to achieve. By converting wind tunnel data into high-speed, ultra-detailed visualizations, NASA is revolutionizing how we test, design, and perfect the next generation of flight technology for the nation."
