The efficient direct optimization method is developed for aerodynamic shapes design at transonic and supersonic flow regimes. The method combines Newton based algorithm with CFD modeling and is capable of handling large number of design variables. Aerodynamic drag is considered as the objective function minimized under lift capability, volume and overall dimensions constraints. The efficiency of the method is demonstrated on examples of two-dimensional and axisymmetric aerodynamic shapes design.
