This paper focuses on investigation of a numerical method for transient temperature distribution, in order to analyze one kind of malfunction of turbine nozzle guide component of a turbo‐fan aeroengine. Thermal fatigue acts as the most important factor resulting in cracks at nozzle guide vanes and severe cracks produced may form failure of the component of the engine. However, transient temperature variety of vanes at start and stop processes of the engine causes thermal fatigue. So, basic analysis of transient temperature distribution and especially a new numerical method for transient temperature calculation in this paper have significant meaning for improving the reliability of aeroengines.
