Abstract:

This work presents how aerodynamic improvements can be achieved by using a multidisciplinary approach to design a morphing aerofoil. The main challenge is to satisfy the requirements coming from different branches of engineering: our approach is considering concurrently all the involved disciplines and their mutual interactions from an early development phase, throughout all the analyses and optimisations, up to the final model. This contribution focuses mainly on the aerodynamic and structural aspects involved in a morphing aerofoil: Firstly we present a method to obtain the morphing requirements from the results of a trajectory optimisation, formulated in such a way to allow exploitation of span-wise aerofoil morphing. Secondly, we describe the static aeroelastic analysis tool that has been used both for evaluating the developed design concepts and subsequently in the aero-structural optimiser. The aero-structural multidisciplinary optimiser will be presented in the final part of this contribution, together with test cases showing the details of performance improvements achievable with the multidisciplinary technique.
