Scientists using owl as inspiration for new aircraft engines

According to new study, a team of scientists are using owl as an inspiration for developing aircraft engines that will make less noise compared to those used presently. Researchers found that owls have an advanced stealth technology that allows them to fly practically undetected. Researchers tried to determine how the creature managers to make noise free flight.

Researchers have been trying to study how owl is able to move its wings to rise in the air without making noise while attacking fast moving rodents and other preys. They said that the owl is the king of acoustic stealth. They found that owl was able to the use the energy of flight and convert it into heat in a much more efficient manner than many other birds. Many sub-species of owl are able to fly at frequencies under 2 kilohertz allowing them to fly undetected.

Jinkui Chu, professor of mechanical engineering at the Dalian University of Technology in China believes that the technology can be used to make aircraft engines quieter. He said scientists can copy mechanisms to quieten machine noises such as the thrum of onshore wind turbines.
