Multifidelity Response Surface Model for Hsct Wing Bending Material Weight

Response surface techniques allow us to combine results from a large number of inexpensive low fidelity analyses with a small number of expensive high fidelity analyses for constructing inexpensive and accurate approximations. The paper demonstrates this approach by constructing approximations to wing bending material weight of a high speed civil transport (HSCT). The approximations employ a la...

Wing Structural Weight Approximations

The paper explores the effect of numerical noise and uncertainties on response surface approximations for wing bending material weight for a high speed civil transport (HSCT) design. The accuracy of the response surface approximations is improved by identification and repair of outliers present in the data due to noisy structural optimization. The use of correction response surface approximatio...

Hsct Wing Design Trough Multilevel Decomposition

A multilevel decomposition approach for the preliminary design of a High Speed Civil Transport Aircraft wing structure is described. The wing design is decomposed into three levels. The top level uses the FLOPS aircraft synthesis program to generate preliminary weights, mission, and performance information. The optimization criterion is productivity expressed by a productivity index for the spe...
