Aeroelastic model design using an integrated optimization approach
KTH, Superseded Departments, Vehicle Engineering.
2004 (English)In: Journal of Aircraft, ISSN 0021-8669, E-ISSN 1533-3868, Vol. 41, no 6, 1523-1526 p.Article in journal (Refereed) Published
Abstract [en]

An elastic wind-tunnel model was designed with an internal carbon fiber/epoxy composite beam as primary structure and with prescribed static and dynamic behavior. The sequential stiffness and mass design approach was used in order to find a design with resonably representative properties. The integrated stiffness and mass design optimization was shown to improve the quality of the model significantly. It was found that the stiffness and frequency objectives did not cause any significant problem, but the mode shape matching was more involved.
