The Effect of Blade Crop and Skew on the Interaction Tones Produced by a Contra-Rotating Unmanned Aerial Vehicle Rotor System (2025)
Journal Article

Contra-rotating rotor systems are commonly used on unmanned aerial vehicles (UAVs). The periodic unsteady loading on the blades of these rotor systems due to their interaction with the flow field of the adjacent rotor produces a mul...

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.
