Researchers at Texas A&M University have conducted a computational study that validates using a shape-memory alloy to reduce the jarring sounds of commercial airplanes during landing. They say these materials could be inserted as passive, seamless fillers within airplane wings that automatically deploy themselves into the perfect position during descent.
“When landing, aircraft engines are throttled way back, and so they are very quiet. Any other source of noise, like that from the wings, becomes quite noticeable to the people on the ground,” said Darren Hartl, assistant professor in the Department of Aerospace Engineering. “We want to create structures that will not change anything about the flight characteristics of the plane and yet dramatically reduce the noise problem.”
The researchers have described their findings in the Journal of Aircraft.
