Abstract:Aeroengine is a concentrated expression of the national scientific and technological level, industrial design and manufacturing power. High Mach number, high thrust-to-weight ratio and high turbine inlet temperature are the main development directions. The temperature distribution of turbine blades can be revealed through the measurement which is valuable for performance evaluation, failure analysis and turbine blade optimization design. The continuously increasing turbine inlet temperature put forward a higher requirement to the temperature measurement technique in aeroengine. This article primarily introduces three types of contact temperature measurement methods for turbine blade, including thin film thermocouple, crystal temperature sensor and temperature sensitive paint, illustrates the working principles briefly, summarizes the application status at home and abroad, concludes the benefits and drawbacks, and forecasts the development direction of the three temperature measurement methods.
