Description/Abstract
A midrange approximation method for design optimization is formulated. This utilizes intermediate response
variables, amenable to simple polynomial representation, to provide a reasonable approximation over a trust region.
It has applications to computationally expensive, nonlinear optimization problems where a designer’s knowledge
may be exploited to select appropriate intermediate variables. Application to the preliminary structural design of
a fan blade is illustrated in two case studies; results for a global optimization strategy and a direct search have
been included for comparison. Significant improvement in the number of function calls necessary to identify a
local optimum is demonstrated in the case studies considered.
