Abstract

Gas turbine blades work in the harsh conditions of high temperature, high pressure and rapid rotation. The impact of the surrounding environment will bring a lot of interference to the process of radiation thermometry, which will produce reflection on the surface of the measured blades. Aiming at the problem of temperature assessment within the operational setting of turbine blades, it is analyzed that the radiation of the surrounding environment will change with the position of the target blade, which brings challenges to the calculation of reflected radiation. In this paper, we examine the reflected radiation errors at different locations and at different temperatures by building a three-dimensional blade model and calculating the angular coefficients between the blades.
