  1. A temperature-cancellation method for anodized-aluminum pressure-sensitive paint (AAPSP) gives time-resolved pressure maps in a hypersonic flow.
  2. 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.
  3. Surface temperature increase due to aerodynamic heating can be captured by AATSP.
      • Time-resolved temperature maps including Gortler vortices were captured  by AATSP.
