Comparison of Multidisciplinary Design Optimization Codes for Conceptual and Preliminary Wing Design

摘要

The results produced by two multidisciplinary design optimization programs for the analysis and optimum design of a benchmark regional aircraft wing are compared. One of the programs uses a simple beam model and is suitable for conceptual design whereas the other uses a three-dimensional finite element model and is suitable for preliminary design. Results for stress, displacement, vibration, and flutter analyses of the initial design configuration show good agreement, as do those for optimization with stress and flutter constraints.
