Researchers at the University of Bristol and RMIT University in Australia have uncovered new insights into the secrets of hovering kestrels that could revolutionize the way delivery drones navigate gusty city air.
Using advanced motion capture technology typically used in blockbuster movies, scientists were able to observe how kestrels remain motionless in the air while hunting for prey. By studying the unique wind-hovering flight behavior of these small falcons, researchers hope to apply their findings to improve aircraft and fixed-wing drones’ ability to handle turbulence and high winds.
The study involved observing two Nankeen Kestrels, named Kevy and Jedda, as they hovered in a wind tunnel at RMIT University. By fitting the birds with reflective stickers and tracking their movements, researchers discovered that kestrels excel at keeping their heads still and adjusting the shape of their wings to cope with turbulent air.
Dr. Abdulghani Mohamed, lead researcher at RMIT, explained that the kestrels’ wing-morphing abilities could inspire new technologies in aircraft and drones, potentially leading to more stable flight in windy conditions. This innovation could have significant implications for drones used in postal deliveries and other critical operations in challenging environments.
Associate professor Dr. Shane Windsor from Bristol University highlighted the potential for scaling up these findings to commercial aircraft, emphasizing the importance of studying bird flight for new insights into aircraft design. By learning from nature, engineers may discover more efficient ways to navigate natural environments and improve aircraft performance.
Overall, the research on kestrels’ hovering abilities offers a promising avenue for enhancing drone technology and aircraft design, showcasing the valuable lessons that can be learned from observing the natural world.
