The project:
With the emergence of Urban Air Mobility (UAM) systems, the aeroacoustic consideration is elevated to center stage in the design process and no longer treated as a design constraint. However, the optimal control settings or shape of a design that correspond to minimal far field noise is typically not known as a priority. This challenge is compounded by the fact that noise and aerodynamic design objectives are often competing. The proposed project aims to numerically investigate, using high-fidelity simulation, the complex noise generation and radiation mechanisms of isolated and installed propeller configurations. The numerical efforts are complemented by experimental validation. In addition, an efficient adjoint-based optimization framework will be developed to minimize the tonal and broadband noise components of propeller-powered configurations via shape optimization. The baseline and optimized designs will be studied both numerically and experimentally. The outcome of this project is expected to elucidate various important physical mechanisms responsible for UAM noise and provide a critical enabling technology for the UAM community to efficiently predict and minimize the noise from their designs. Successful candidate will have access to large-scale high performance computing resources on ARCHER2, UK’s largest supercomputing facility. In addition, the successful candidate will also be offered a rare opportunity to interact and collaborate with major aerospace industry and research establishments around the world.
