Aerodynamics and Aeroacoustics of Advanced Air Mobility vehicles: from Mid-fidelity Simulations to Wind Tunnel Tests | with professor Zanotti
On Friday, July 18 at 11:30 am, the Department of Mechanical and Aerospace Engineering-DIMEAS of Politecnico will host the seminar entitled "Aerodynamics and Aeroacoustics of Advanced Air Mobility vehicles: from Mid-fidelity Simulations to Wind Tunnel Tests" presented by professor Alex Zanotti from the Department of Aerospace Science and Technology of Politecnico di Milano.
Innovative concepts for Advanced Air Mobility (AAM) vehicles represent one of the most investigated topics in aeronautics. These aircraft characterized by the capability of vertical take-off and landing (eVTOLs) present unprecedented challenges due to their unique design, particularly characterized by several rotors/propellers. Therefore, eVTOLs design requires fast and reliable tools to investigate key aspects such as interactional aerodynamics and acoustic footprint to be thoroughly addressed to gain regulatory approval and public acceptance. The seminar will provide coverage of the research effort of the Aerodynamics Laboratory of Politecnico di Milano (POLIMI) devoted to the study of the interactional aerodynamics mechanisms related to multi-propeller aircraft configurations. In particular, the technologies and methodologies pertaining to the study of this topic will be presented going from the use of state-of-the-art wind tunnel experiments to mid-fidelity simulations performed using DUST, a vortex-particle-method based software developed at Department of Aerospace Science and Technology of POLIMI. Key topics covered in this seminar include the effects of the principal interactional aerodynamics phenomena occurring on innovative aircraft/rotorcraft configurations along with their flight envelope (i.e. propeller-propeller, propeller-wing, blade-vortex-interactions, vortex ring state) and their main effects on aerodynamic performance and acoustic footprint.
