AE 590 Seminar Speaker: Kevin Li - Interactional Aerodynamics and Aeroacoustics: From Measurements to Multi-Fidelity Modeling

Abstract:
Vertical Take-off and Landing (VTOL) technology is rapidly transforming the aerospace landscape, with applications spanning civil industries like transportation, entertainment, and agriculture, as well as critical military operations such as surveillance, strikes, and logistics. Despite its growth, VTOL technology faces major challenges, including complex fluid-structure interactions and uncontrolled noise levels. To overcome these challenges in low-Mach flights, this seminar will present the RAA Lab’s research efforts to address these questions. How can we safely land VTOL aircraft onto naval ships during the ocean storm conditions? How can a micro wing generate excessively loud noise, challenging the conventional aeroacoustics? How can we extend the conventional aeroacoustic theories to multi-phase flows?
