Researchers hope they could inspire new drone and plane designs able to better cope with turbulence.
New insights into the secrets of hovering kestrels could help delivery drones navigate the gusty air in cities, scientists at the University of Bristol and RMIT University in Australia
Its hoped the research could eventually help engineers develop aircraft and fixed-wing drones better able to deal with turbulence and high winds.Camera and motion capture technology enabled researchers to observe two Nankeen Kestrels, called Kevy and Jedda, as they hovered in a wind tunnel operated by RMIT.
Previous studies have examined birds flapping - less useful for gaining insights into how aircraft fly. His team found the kestrels were excellent at keeping their heads still - moving less than 5mm - while hunting despite the buffeting air. Strong wings and turbulence can limit the operation of drones. Those operating in windy environments, such as postal deliveries likeEven small scale drones operating in cities have to navigate the wind-tunnel like blasts around buildings familiar to big-city dwellers.
