Aero Tech Talks Seminar Series

CFD-based Aerodynamic Shape Optimization

Description: The pursuit of optimal aerodynamic shapes transcends various fields, demanding innovative approaches in design and optimization. This talk will examine the latest developments in Computational Fluid Dynamics (CFD)-based design optimization, addressing the critical challenges and innovative solutions in shaping aircraft components for enhanced efficiency. We will explore the integration of CFD with structural mechanics to optimize wing aerodynamics, enhancing lift-to-drag ratios and reducing structural weight. The discussion will extend to the aerodynamic optimization of propellers and turbofans, highlighting how CFD facilitates the design of propulsion systems that integrate optimally with the airframe. By employing multidisciplinary optimization (MDO) approaches, we have advanced the design of these key aircraft components, considering complex interactions and design constraints. We will focus on adjoint methods for efficient gradient computation, which is essential for handling the large number of shape and sizing variables required in aircraft design. The talk will present case studies demonstrating the successful application of these methods in optimizing aircraft wings, turbofans, hydrofoils, wind turbines, and more.
