AI Insight
Researchers from Brown University have discovered new details about how birds flying in V-formation conserve energy. The study reveals that birds in formation use flatter wing flaps compared to solo flight, which allows them to take advantage of the aerodynamic benefits created by the bird flying ahead of them. This flatter flapping pattern helps the birds maximize the upwash generated by their neighbors' wings, reducing the energy cost of sustained flight.
Why it matters
These findings could inform the design of more efficient aircraft formations and autonomous aerial vehicle systems. Understanding the precise mechanisms birds use to save energy in formation flight may lead to fuel savings in aviation and improved algorithms for coordinating multiple drones or aircraft.
Understand the Science
Scientists have known for years that birds like geese and ibises gain an aerodynamic advantage from flying in a “V” formation. Now, researchers from Brown University have provided new insights into the nature of that advantage.
