Abstract : Since its introduction in the mid-1960's, optical pyrometry has gained widespread acceptance as an invaluable technique for turbine blade temperature measurement in engine research and development programs. This paper highlights some of the more important aspects of turbine pyrometry in relation to its acceptability for flight usage. Difficulties still remain, however there are clear signs that flight pyrometry will very probably be employed in the next generation of high performance combat aircraft engines. Topics discussed include: Interchangeability; Peak blade temperature measurement; Radiation interference; Optics contamination; and Measuring range.
