Research themes

Three connected lines
of inquiry.

Research questions move from sound radiated by airfoils to the unsteady loads and performance of aerodynamic systems.

Conceptual illustration of acoustic waves radiating from an airfoil in turbulent flow

Aeroacoustics

Airfoil noise and sound radiation in turbulent flows.

Conceptual illustration of unsteady flow structures around a rotating aerodynamic system

Unsteady flows

Unsteady loading, tip-gap flow, and rotor–stator interaction.

Conceptual illustration of a grid fin in low-subsonic flow

Aerodynamic performance

Low-subsonic grid-fin performance and flight applications.

Conceptual research illustrations; not experimental images or simulation results.

Current work

Drone acoustic
localization.

An ongoing project exploring passive detection and localization from the sound of drone motors and propellers.

Conceptual illustration of an acoustic array; not an experimental setup.

Research project

Listening for location.

The project aims to develop a passive system that detects and localizes drones from their acoustic signature.

  • Proposed methodsThe planned approach combines a microphone array, time- and direction-of-arrival estimation, and machine learning for sound classification and background-noise separation.
  • Current stageThe available project plan describes design and development planning, with offline signal-processing and machine-learning validation planned before real-time deployment and field evaluation.
