A pyrometer was built for the measurement of the surface temperature of turbine rotor blades on operating development engines. Two new concepts were used: a purged, line-of-sight viewing tube, and a method of signal processing to reject the interference of carbon particles in the turbine gases.
This report describes the new system and the results obtained in testing on development engines. The data have been analyzed and recommendations are made to improve the measurement accuracy further. The pyrometer has potential for measuring, condition monitoring, and in-flight engine control.
