On-field measurements following the EASA guidelines on noise measurements of unmanned aircraft systems lighter that 600 kg (2025)
Presentation / Conference Contribution

Unmanned Aircraft Systems (UAS) have gained increasing attention, leading to the development of noise measurement protocols, such as the 2023 guidelines from the European Union Aviation Safety Agency (EASA). These guidelines focus on noise measuremen... Read More about On-field measurements following the EASA guidelines on noise measurements of unmanned aircraft systems lighter that 600 kg.

Integrated U-space societal acceptance assessment: energy-based and perception-based acoustic metrics. (2025)
Presentation / Conference Contribution

Innovative Air Mobility (IAM) systems are progressing within the European U-space framework to promote efficient and environmentally friendly air transport. The ImAFUSA project contributes by developing an integrated U-space assessment tool to evalua...

The effects of time-variant characteristics of unmanned aircraft system noise on reported annoyance (2025)
Presentation / Conference Contribution

Flight missions of Unmanned Aircraft Systems (UAS) are inherently unsteady due to the complex interactions between the environment (e.g., wind conditions) and the operative flight control system. These interactions result in the unsteadiness of the a... Read More about The effects of time-variant characteristics of unmanned aircraft system noise on reported annoyance.

Reducing Tonal Noise of Contra-Rotating Unmanned Aerial System Rotors via Blade Rake Angle Adjustment (2025)
Journal Article

This paper investigates the effect of blade rake angle on the tonal noise produced by contra-rotating rotor systems suitable for use on small multi-rotor unmanned aerial systems (UAS). This investigation utilises semi-analytical, numerical, and exper... Read More about Reducing Tonal Noise of Contra-Rotating Unmanned Aerial System Rotors via Blade Rake Angle Adjustment.

Aeroacoustics and psychoacoustics characterization of a boundary layer ingesting ducted fan (2025)
Journal Article

A comprehensive wind tunnel investigation was conducted to analyze noise generation, propagation, and perception mechanisms in a boundary layer ingesting (BLI) ducted fan through integrated aeroacoustic and psychoacoustic assessments. The study exami... Read More about Aeroacoustics and psychoacoustics characterization of a boundary layer ingesting ducted fan.
