The testing methods and precise distribution of temperature fields of turbine nozzle are of practi-cal and theoretical significance for the design and improvement of turbine nozzle. Temperature-sensitive paint was adopted to measure the surface temperature of HPT nozzle under maximum operating conditions. The test results proved that the temperature-sensitive paint can adhere to turbine nozzle firmly in the course of experiment with clear isotherm;the temperature field distribution of turbine nozzle was measured successfully, which could be helpful to analyze the thermal stress and life of the turbine nozzle.
