A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by ...

Owl wing design reduces aircraft, wind turbine noise pollution Serrated edge of owl wings makes them quieter than other birds, can help inform airfoil designs Date: January 18, 2022 Source ...

Lauder to design the airfoil, a cross section of an airplane wing. Combining their knowledge of shark biology and aerodynamics, the team examined denticles, small projections that are made of the ...

While previous research has predicted that serrations on the trailing edge can suppress sound from airfoils, exactly how these could cut noise, and whether these design changes produce universal ...

a wing with a lot of lift typically has a lot of drag, and a wing with little drag typically has little lift. The two features below present the basics of airfoil design and flight.

Called the “Vindskip,” the Norwegian design uses the high sides of its container ships as sails, turning the whole vessel into a wind-assisted airfoil. Designed by Lade AS, the Oslo-based ...
