Studying Owls to Improve Aircraft

Studying Owls to Improve Aircraft | Biomimicry | Scoop.it
Many owls have the extraordinary ability to fly in almost complete silence. Could this adaptation have implications for the way we design aircraft?

Big Idea, Small Compressor: Silent Fan Inspired by Nature

Big Idea, Small Compressor: Silent Fan Inspired by Nature | Biomimicry | Scoop.it

"Low noise levels are important in industries where the user can benefit from having the air compressor within close proximity to the work station, such as in the woodworking or automotive industry. The GA VSD+ uses a technologically advanced fan to help achieve noise levels low enough for a normal conversation to be held while the machine is running. The fan blade utilizes a design with a serrated edge that is inspired by the aerodynamic and mostly silent wings of an owl. With an aerodynamic design, the fan needs less energy to cleave through the air, making it more energy efficient."

Secret of Owls' Silent Flight Revealed by Scientists

Secret of Owls' Silent Flight Revealed by Scientists | Biomimicry | Scoop.it

"The secrets of owls' near silent wings has been revealed by scientists who could now use the technology to develop quieter aircraft. A new study has shown how the bird of prey's naturally evolved plumage gives the hunting advantage of 'acoustic stealth', allowing it to sneak up on targets. Research found that many owl species have developed feathers which can effectively eliminate the aerodynamic noise from their wings as they cut through the air."

Owls' Ability to Fly in Acoustic Stealth Provides Clues to Mitigating Conventional Aircraft Noise

Owls have the uncanny ability to fly silently, relying on specialized plumage to reduce noise so they can hunt in acoustic stealth. Researchers from the University of Cambridge, England, are studying the owl's wing structure to better understand how it mitigates noise so they can apply that information to the design of conventional aircraft.
