An aerodynamic design procedure that uses neural networks to model
the functional behavior of the objective function in design space
has been developed. This method incorporates several improvements
to an earlier method that employed a strategy called
parameter-based partitioning of the design space in order to reduce
the computational costs associated with design optimization. As
with the earlier method, the current method uses a sequence of
response surfaces to traverse the design space in search of the
optimal solution. The new method yields significant reductions in
computational costs by using composite response surfaces with
better generalization capabilities and by exploiting synergies
between the optimization method and the simulation codes used to
generate the training data. These reductions in design optimization
costs are demonstrated for a turbine airfoil design study where a
generic shape is evolved into an optimal airfoil.
