Contra-rotating rotors in advanced unmanned aerial vehicles (UAVs) can offer enhanced aerodynamic performance and pose significant aeroacoustics challenges. This study experimentally investigates the far-field noise cha…
View researchRotor blades in eVTOL aircraft are often assumed rigid in noise studies, but their thin, slender design makes them prone to large aeroelastic deformations during edgewise forward flight. Measurements in an anechoic wind…
View researchDrones are promising transport means for the last-mile deliveries in urban communities. However, low-altitude aviation can cause severe noise pollution, leading to the requirement of rational operational strategies to m…
View researchOwls are known as silent predators of the night. Compared to other famous raptors such as falcons and kestrels, owls are not fast at all. Instead, after millions of evolution, owls have special adaptations which enab…
View researchTurbofan engines are commonly used on modern commercial aircrafts and have become a significant source of noise pollution. The tonal noise generated by turbofan engines has been extensively studied, and noise reducti…
View researchSystematic rotor noise study is conducted in AANTC including analytical measurement, numerical simulation and experimental measurements. Theoretical noise prediction models are developed to compute the noise radiation…
