Abstract: To assure air-cooled turbine blade of being able to operate safely and reliablely during continuous variation of mechanical, particularly thermal loads, it is necessary to caleulate the transient temperature field of blades. In this paper the finite element method for computation of transient two-dimensional temperature distribution is discussed, the calculation of transient temperature field for a middle cross section of air-cooled blade is made and discussed.
