Paper Abstract

A high speed, high resolution spectrum measurement system based on fiber-spectrometer was built to diagnose the high temperature hypersonic combustion flow. The theoretical models of the spectral radiance and transmittance of the hypersonic combustion flow were established in this paper. The spectral radiance and transmittance of the hypersonic combustion flow were measured at the combustion wind tunnel of BISLMV. Preliminary experiments showed that the spectral radiance behaved not like typical gas radiation but have a continuous spectrum, and the spectral transmittance of the combustion gas flow was about 0.9 in the spectral range 500-900nm without strong spectral selection. The results obtained in this paper will benefit the surface temperature measurement of the thermal protection materials of space vehicle tested at BISLMV.
