Aeroacoustics
An experimental study of rotor aeroacoustics with aeroelastic effects under edgewise flight conditions
Rotor 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 ....

Low noise UAM planning in the community
Drones 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 operatio....

Owl inspired material for trailing edge noise control
Owls 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 adap....
