The review article is devoted to detailed analysis of known methods and ways for measuring the temperature parameters in the area of directional solidification of the melt of the rotor blades of gas-turbine engines. The analysis of existing methods of temperature control such as contactless methods and contact ones is made. As found, in further progress and development of devices and methods of temperature analysis, priority belongs to pyrometry. Relied on the advantages and disadvantages of existing methods, it is determined that the solution of this problem is possible with use of spectral and imaging pyrometry.
