The flutter of a rectangular plate with variable thickness, placed in the supersonic gas flow, was analyzed with application of the linear piston theory. A solution for optimization of the plate thickness’ distribution was proposed for the case of some additional constraints. The critical velocity of the flow under different values of operation factors was obtained with tetramerous approximation using Galerkin method. Comparison of results was made.
