Multidisciplinary design analysis and multi-objective optimisation applied to aircraft wing
نویسندگان
چکیده
Design of complex high-tech systems typically requires an integrated analysis of the multiple interacting physical phenomena that jointly influence the overall system’s behaviour. For aircraft wings, for example, the aerodynamic loading and the wing structural deformation strongly interact, with their balance determining the overall wing behaviour. This balance must be evaluated for the different operational conditions the wing is exposed to, such as the cruise, manoeuvre, or take-off conditions. In addition, various objectives and constraints, based on for example, drag, lift, weight, range, or fuel consumption, must be taken into account when designing aircraft wings. The choice depends on the key design goals being addressed. This requires high flexibility in the selection of the results of the integrated design analysis to adequately formulate the appropriate (constrained) optimisation problem representing the considered design case. The current work presents a flexible approach for multidisciplinary design analysis and optimisation, and its application to aircraft wing design. The achieved results show significant improvements of the wing performance for different design goals, demonstrating the effectiveness and flexibility of the proposed approach.

This paper examines the evolutionary approach for aircraft design optimization. Several niching and elitist models are first applied to Multiple-Objective Genetic Algorithms (MOGAs). Numerical results suggest that the combination of the fitness sharing and the best-N selection leads to the best performance. The resulting MOGA is then applied to multidisciplinary design optimization problems of ...
