Is considered a two-dimensional finite element analysis of unsteady thermal regime is made of heterogeneous layers of composite construction. The degree of influence of individual geometric design changes on the character of distribution of temperature on its volume. Heat is produced from internal volumetric sources of heat, removal of heat from the outer surface by convection. The calculation of the temperature field using two-dimensional heat conduction equation (Fourier equation)

We consider testing program finite element calculation of non-stationary thermal mode design of complex shape. We compare the results of calculation of temperature fields of design data real test. Determine the accuracy of the modeling of thermal processes in the body structure. Objective: To compare the results of thermal calculation of composite design data real test. To determine the accuracy of the finding of the program created by the temperature calculation. The design takes physical tests on heating external convective heat flux. The temperature value at the control points in the heating process is continuously recorded with a thermocouple. The results of measurements and calculations are compared. As a result of comparison, the conclusion about the accuracy of calculation of the temperature field created by the design calculation program.
