Abstract
A design methodology which uses a variable-complexity modeling approach in
conjunction with response surface approximation methods has successfully been
developed. This approach uses simple models to improve the accuracy of the
response surface and reduce the number of analyses based on complex models
required for constructing the surface. Simple models are first used to
eliminate "nonsense" portions of the design space. Then a response surface
based on the simple models is used to reduce the number of unknown
coefficients that define the response surface. This approach is applied to
an example problem of wing design for a High Speed Civil Transport (HSCT)
aircraft involving a subset of four HSCT wing design variables.
