This work quantifies aeroacoustic benefits of trailing-edge serrations in multi-rotor systems using GPU-accelerated LES. We demonstrate a noise reduction of up to 2.4 dB and a 7.8% thrust boost from rotor-wing interactions. These findings offer a scalable path for the UAM and drone industries to design quieter, more efficient distributed propulsion architectures.
