Realistic aerodynamic simulation reveals how hummingbirds hover

21 November 2014

The most detailed aerodynamic simulation of hummingbird flight conducted to date demonstrates that it achieves its aerobatic abilities through a unique set of aerodynamic forces more closely aligned to those found in flying insects than in other birds. The simulation was produced by Vanderbilt engineers working with a biologist from the University of North Carolina at Chapel Hill.

Secret behind hummingbird aerobatic feats discovered

Just how tiny hummingbird[s] can hover in front of a flower before darting to another has always puzzled scientists.

But new research shows that this ability is more closely related to those found in flying insects than to other birds.

A three-dimensional aerodynamic simulation demonstrated that the tiny birds make use of unsteady airflow mechanisms to generate invisible vortices of air that produceā€¦
