Spectral pyrometry of surface and flame

Abstract

Abstract The development of high-speed aircraft requires the study of high-temperature materials and of combustion processes in engine combustion chambers. One of the main parameters in these studies is the temperature, which must be measured up to 3000K. Such high temperatures can be measured only by non-contact methods. One of these methods is spectral pyrometry, which is based on temperature measurement from the energy distribution in thermal radiation spectrum of investigated object. This paper presents the results of spectral pyrometry application to measure the surface temperatures and hydrocarbon flame temperatures.
