Temperature Indicating Paints as They Assist in Gas Turbine Design Processes

High temperature turbine technology demands new techniques in development testing as well as new design approaches. The use of temperature indicating paint is an example of a test technique that has assisted significantly in the design and development of high temperature turbine and combustion hardware. Although temperature indicating paint is not a new device in industry, the application in high temperature, high force-field gas streams requires special techniques, which are described here and which have been used with a high degree of accuracy and reliability in the design and testing of combustion and turbine components.
