In this paper we propose a method for determining a combination of layer thicknesses
ensuring the predetermined maximum allowable temperature at the layer boundaries
provided that the number of variable layers is not equal to the number of controlled
points. We present a numerical example of solving the problem of designing a three-layer
structure subject to bilateral heating, with the requirement that the maximum tempera-
ture of the construction inner layer should not exceed 1073 K. This requirement is satis-
fied by varying the thickness of the outer thermal insulation layers. The solution obtained
by using the developed method, asymptotically approaches the optimal solution in ex-
treme setting of the problem.
Keywords:
thermal designing, composite thermal protection structures, optimal solution.
