The preliminary design of a jet aircraft wing, through the use of an integrated multidisciplinary design environment, is presented\r\nin this paper. A framework for parametric studies of wing structures has been developed on the basis of a multilevel distributed\r\nanalysis architecture with a ââ?¬Å?hybrid strategyââ?¬Â process that is able to perform deterministic optimizations and tradeoff studies\r\nsimultaneously. The particular feature of the proposed multilevel optimization architecture is that it can use different set of\r\nvariables, defined expressly for each level, in a multi-level scheme using ââ?¬Å?low fidelityââ?¬Â and ââ?¬Å?high fidelityââ?¬Â models, as well as\r\nsurrogate models. The prototype of the design environment has been developed using both commercial codes and in-house tools\r\nand it can be implemented in a geographically distributed and heterogeneous IT context.
