Material grading for improved aeroelastic stability in composite wings

Aeroelastic Analysis of Composite Wings

An aeroelastic stability analysis is presented for high-aspect ratio composite wings. The structural model is based on an asymptotically correct crosssectional formulation and a nonlinear geometric exact beam analysis, both derivable from 3-D elasticity. A new 2-D unsteady inflow finite-state theory is considered for the aerodynamic part of the solution. Theodorsen theory is also implemented an...

Design of Composite Structures for Improved Aeroelastic Performance

Despite the benefits of composite structures, it is only recently that the main load bearing structures in large aircraft such as the Boeing 787 and Airbus A350 have started to be manufactured using carbon fibre composites. Even then, the unique directionality properties of composite laminates and design possibilities have yet to be exploited to improve the aircraft performance. In this study a...

Aeroelastic Roll Control for High Aspect Ratio Wings

The undersigned hereby certify that they have read and recommend to the Faculty of Aerospace Engineering for acceptance a thesis entitled " Aeroelastic Roll Control for High Aspect Ratio Wings " Summary Modern aircraft tend to be light and slender. The high aspect ratio reduces the induced drag, increase fuel efficiency, and provide enough lift at low speeds. Therefore such wing types are used ...
