- A temperature-cancellation method for anodized-aluminum pressure-sensitive paint (AAPSP) gives time-resolved pressure maps in a hypersonic flow.
- The developed AAPSP was demonstrated in the Mach 7.1 Hypersonic and High Enthalpy Wind Tunnel at The University of Tokyo, Kashiwa Campus.
- Characteristic pressure patterns of shock-shock interaction and Gortler vortices were captured by AAPSP.
- Surface temperature increase due to aerodynamic heating can be captured by AATSP.
- Time-resolved temperature maps including Gortler vortices were captured by AATSP.
