Nonlinear Aerostructural Optimisation of Boundary Layer Ingesting Fan

Supervisory Team: Prof. Ali Elham, Dr. Jie Yuan

Project description:

To meet the objectives of the Paris Climate Agreement, aviation (~3% of human global CO2 emissions) must do its share. The target for air transportation is a 75% reduction in CO2 and a 90% reduction in NOx by 2050. The European Green Deal even aims to achieve climate neutrality by 2050. To achieve such goals, the path forward is minimising aircraft weight and drag and moving towards emissions-free energy sources, storage and conversion systems. The sector is looking at new energy carriers (batteries, fuel cells, hydrogen), distributed propulsion concepts, and new configurations such as blended-wing-body. Boundary Layer Ingestion (BLI) is a promising technology for future propulsion systems, which can significantly reduce energy consumption. However, the design of boundary layer ingesting fans is challenging due to aeromechanical problems (e.g. flutter or high cycle fatigue) due to the distortion caused by BLI. In this project, we will extend our high-fidelity multidisciplinary design optimisation (MDO) framework for the design of BLI fans. The proposed MDO is based on adjoint aerostructural optimisation, augmented with machine learning, considering complex aerostructural behaviour affected by BLI-distorted aero loads.

We are particularly looking for UK national students, either having or expecting to achieve a first-class degree in aerospace engineering. You should have studied CFD, FEM, and optimisation with a particular interest towards high-performance computing.

You will join a leading Engineering Faculty with an excellent record of collaborative research with industry and academic institutions in the UK and abroad. In September 2013, the School of Engineering received an Athena SWAN Bronze award in recognition of our continued commitment to improving women’s equality in science and engineering.
