"Here, he said, could be some clues for developing ultraquiet aircraft and wind turbines.
"The owl is almost completely silent in flight," said Sharma, an Iowa State assistant professor of aerospace engineering and Walter W. Wilson Faculty Fellow who started working in aeroacoustics – the noise associated with air flow – during graduate school and a previous position at GE. "Owls are not only silent in gliding flight, but also in flapping flight, which is amazing."
And then Sharma picked up the wing (a specimen collected by Iowa State avian ecologist Stephen Dinsmore) and pointed out the three-part "owl hush kit" that's responsible for silent flight."
