Objectives

  • Analyze fundamental aeroacoustic sources of noise and their aerodynamic origin.
  • Evaluate, both numerically and experimentally, sources of noise in different mechanical systems.
  • Discuss and decide upon the most relevant acoustic parameters to be monitored and measured for a specific aerodynamic system.
  • Design a strategy to work within noise regulations without compromising aerodynamic performance.

Target Audience

  • Project managers, designers, research engineers or research developers (RDs) working (or intending to) in the aerospace, aerodynamic, propulsion, wind energy industry or tackling the aerodynamic and aeroacoustics design of a specific mechanical system.
  • In particular the programme is particularly suitable for professional engineers with an applied, experimental or numerical background (e.g. mechanical, aerospace, electric, applied physics, mathematics) and professionals with a mechanical (or similar) engineering background interested in the fundamentals of computational methods to derive noise sources and their propagated sound.
  • Employers range from wind turbine, engine, ventilation system and aircraft manufacturers to aerospace institutes. In several industries, investments aimed at noise reduction have increased significantly due to stricter regulations and updated sustainability policies with new targets. Engineers who work on engines or propulsion will continue to be needed as the emphasis in design and production shifts to rebuilding existing aircraft so that they are less noisy and more fuel efficient. Additionally, growing interest in unmanned aerial systems will also help drive growth of the occupation. Overall, this has led to a considerable increase in the demand of aeroacoustics expertise in future engineers, who now need new skills to combine aerodynamics and aeroacoustics in their designs.
