Abstract For analyzing the fracture of the turbine blade, the temperature and the temperature distribution of the turbine blades are the important basis. When the engine working at high temperature, due to the engine containing a large amount of water vapor (H2O), carbon dioxide (CO2), so the temperature measuring of the turbine blade will produce a complex heat radiation.By analyzing the infrared absorption characteristics of high temperature gas, the transmittance of the atmosphere is calculated under different conditions of engine combustion chamber, and the measurement wavelength will be optimized.
