The problem of steady state heat conduction in a functionally graded open-cell metal foam thermal insulation is studied. The mass is minimized by varying the solidity profile for a given thickness. An optimality condition is derived and the optimization problem is reduced to that of an ordinary, nonlinear differential equation, which is solved numerically. The results include optimum cell size variation through the thickness of the insulation for given aerodynamic heating and the corresponding temperature distribution. It is shown that for a given thickness using a functionally graded insulation is predictably lighter than uniform one.
