UTOPIAE - Early stage researchers for aerospace systems of the future

The mission of the training and research network UTOPIAE is to:

• Train, by research and by example, 15 Early Stage Researchers (ESR) in the field of Uncertainty Quantification and Optimisation and to become leading independent researchers and entrepreneurs that will increase the innovation capacity of the EU.
• To equip the researchers with the skills needed for successful careers in academia and industry.
• To develop, through the ESR’s individual projects, fundamental mathematical methods and algorithms to bridge the gap between Uncertainty Quantification and Optimisation and between Probability Theory and Imprecise Probability Theory for Uncertainty Quantification and to efficiently solve high-dimensional, expensive and complex engineering problems.

Project title: Robust design of a shock bump for natural laminar flow over a wing

At the DLR-Institute of Aerodynamics and Flow Technology the ESR will be involved in the robust design of a shock bump for natural laminar flow over a wing. The objective is to further develop and use robust and reliability-based optimisation techniques to design a shock bump that is less sensitive to small random changes in onflow conditions (operational conditions) and geometrical uncertainties, like manufacturing tolerances or degradation, in order to maintain natural laminar flow (NLF).

Objectives:

• To develop a suitable parameterization of the bump in 2D and 3D
• To investigate different measures of robustness suitable in the context of NLF
• To define input PDFs for the uncertain parameters in shock bump and NLF models
• To make use of efficient nonintrusive UQ methods for many uncertainties, including gradient-enhanced surrogate models and reduced-order models

Expected Results:

• A demonstration of the efficiency and effectiveness of the robust design methodology on 2D (airfoil) cases and 3D wings in the transonic flow regime
• A validated software framework for robust design

Planned Secondments:

• INRIA (M9-12) on robust and reliability-based design optimisation algorithms
• Airbus GmbH (M30-33) to apply the developed process
