Flow interactions lead to self-organized flight formations disrupted by self-amplifying waves

J. W. Newbolt, N. Lewis, et al.

This groundbreaking research by Joel W. Newbolt, Nickolas Lewis, Mathilde Bleu, Jiajie Wu, Christiana Mavroyiakoumou, Sophie Ramananarivo, and Leif Ristroph explores the collective flight dynamics of flapping flyers. Discover how pairwise interactions can lead to stable crystalline formations and the intriguing role of 'flonons' that disrupt these patterns in larger groups.

Abstract
This study investigates the collective flight dynamics of flapping flyers, focusing on linear formations. Using robotic experiments and a wake interaction model, the researchers demonstrate that pairwise flow interactions promote crystalline arrangements, but this order is disrupted by self-amplifying positional waves, termed "flonons." Larger groups exhibit increased instability due to flonon amplification, but introducing variability among individuals can stabilize larger, disordered flocks.
