Aeroelastic Tailoring: Promise and Challenges.

Aeroelastic tailoring is a methodology to design aircraft lifting surfaces by making use of the directional properties of composite materials. The goal is to minimise the structural weight or to ensure optimal aircraft performance and manoeuvrability. The use of directional properties of composite materials to influence the aeroelastic wing deformations favourably was already a topic of research in the 1980s. This was also the era when the swept-forward wing X-29 was launched. Composites were used for the X-29 to avoid divergence issues while ensuring superior roll performance of the experimental combat aircraft. Aeroelastic tailoring has gained renewed interest in the 2000s because of the availability of novel manufacturing techniques for composite materials. The main differences with the research carried out in the 1980s is that the coupling between in-plane and out-of-plane stiffness, the so-called B matrix, is considered to be zero to avoid warping due to residual thermal stresses after curing of the composite panels. Furthermore, more manufacturing constraints are taken into account nowadays.

This seminar will give an overview of the current state of the art in aeroelastic tailoring research worldwide. Results of aeroelastically tailored wing designs obtained using the methodologies developed at Delft University of Technology will be presented and explained. Finally, challenges for the future and to close the gap between the numerical aeroelastically tailored designs and manufacturable ones will be presented.

Roeland De Breuker is an Associate Professor at the Department of Aerospace Structures and Materials, Delft University of Technology. He is also head of the Smart Structures Laboratory. He joined Delft University of Technology as Associate Researcher in 2005 after he obtained his MSc degree on the nonlinear characterisation and experiments of piezoelectric benders from Delft in 2004. While working as Associate Researcher, he obtained his PhD degree on the development of design tools for morphing aircraft from Delft in 2011. He was a visiting researcher at the DLR in Göttingen and at Clarkson University in Potsdam, NY, and a visiting professor at Airbus Group Innovations in Ottobrunn, Germany. Furthermore, he is international member of the AIAA Adaptive Structures Technical Committee and member of the Advisory Council of the Netherlands Aerospace Centre, Department of Aerospace Vehicles.

Roeland’s main research activities are smart and aeroelastic structures. He is involved in multiple European and national Dutch projects in these two research fields. He was/is involved in the FP7 SADE (on morphing leading edges) and CHANGE (on morphing aircraft design) projects; the CleanSky Smart Fixed Wing Aircraft (for passive load alleviation methods) and LeaTop (on morphing leading edge manufacturing and testing) projects; the CleanSky 2 ReLOAD (on loads alleviation) and MANTA (on novel moveables) project; the Marie Curie project AMEDEO (on multidisciplinary optimisation); the H2020 AGILE (on aeroelasticity in MDO), FLEXOP (on aeroelastic tailored wings for a flight demonstrator) and SABRE (on the development of morphing helicopter blades) projects and the Dutch national projects FLOW and SmartWind (both on smart rotors). Roeland is advising ten PhD students, has graduated three PhD students, and is advising/has advised 60 MSc students. He currently holds 35 refereed journal papers and three patents.

Tea/coffee will be available at 11h45.
