About the Talk:
The need for mitigating aviation environmental impact is driving a signiﬁcant investment in developing aircraft with lightweight and high-aspect-ratio wings for energy eﬃcient ﬂight. These aircraft show interactions between the vehicle motion as a whole and aeroelastic dynamics along with geometrically nonlinear eﬀects that are not considered in current design practice. This problem calls for new models to analyze and simulate the next generation of aircraft with accuracy and computational eﬃciency appropriate for design. This talk will discuss a reduced-order modeling approach to integrate coupled ﬂight dynamics-nonlinear aeroelastic calculations early into the design cycle of aircraft with high-aspect-ratio wings. Numerical results will be presented to discuss the impact of high-aspect-ratio wings on aircraft maneuverability and to demonstrate a new method for predicting ﬂutter bifurcations for aircraft design applications.
About the Speaker:
Dr. Cristina Riso is a Research Fellow in the Department of Aerospace Engineering at the University of Michigan, where she is a member of the Airbus-Michigan Center for Aero-Servo-Elasticity of Very Flexible Aircraft. Before joining Michigan, she received a Ph.D. in Aeronautics and Space Engineering from Sapienza University of Rome. Her research interest is in the modeling and analysis of nonlinear aeroelastic systems, with a focus on problems that involve large structural deflections and interactions between rigid-body motion and structural flexibility. Her current work is in developing coupled flight dynamics-nonlinear aeroelastic models of future commercial aircraft with high-aspect-ratio wings and in using these models for integrating dynamic aeroelasticity constraints into aircraft design optimization.
