Apr 15, 2020 · Research suggests that owl wings have three features that contribute to their silent flight: a “comb” structure (just visible at the wing’s top right), ragged trailing edges (visible …

Mar 11, 2022 · Researchers are using biomimicry to design quieter turbomachinery, airplanes, and drones. The trailing edge of an owl’s wings changes airflow patterns, muffling the noisy …

Through physical experiments and theoretical modeling, the team has developed a 3D-printed wing attachment that reduces wind turbine noise by a remarkable 10 decibels, using the …

Feb 29, 2024 · Owls can fly in near silence thanks to their trailing edge fringe — a layer of feathery fuzz on the back edge of their wing. This fringe dampens sound by breaking up the …

Jan 18, 2022 · Researchers used the characteristics of owl wings to inform airfoil design and significantly reduce trailing-edge noise. The team used noise calculation and analysis software …

Jun 22, 2015 · A newly-designed material, which mimics the wing structure of owls, could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of …

Apr 4, 2025 · Now, the team has succeeded -- through physical experiments and theoretical modeling -- in using the downy canopy of owl feathers as a model to inspire the design of a 3 …

Jan 29, 2022 · Serrated edge of owl wings makes them quieter than other birds, can help inform airfoil designs. Trailing-edge noise is the dominant source of sound from aeronautical and …

Nov 18, 2022 · Owls inspired their invention due to their serrated wings, which break up airflow and absorb sound. They also have a flexible fringe toward their wing’s trailing edge or back …

Jan 20, 2022 · Researchers have replicated the characteristics of owl wings to create new aerofoil designs aimed at reducing trailing-edge noise. The team from Xi'an Jiaotong University in …
