Fast-Responding Cryogenic Pressure-Sensitive Paint with Porous PTMSP-Based Binder

What is it about?

A new pressure-sensitive paint was developed to measure rapidly changing surface pressure in cryogenic wind tunnels. By using a porous structure that allows oxygen to move more easily, the paint responds about six times faster than conventional types, enabling more accurate measurement of unsteady pressure in very low-temperature environments.
