This figure shows the comparison of the spatial distributions of the time-averaged flow field before and after drooping the leading edge in the form of u-velocity sections. With the drooping leading ...

Honey bees and hummingbirds can hover like helicopters for minutes at a time, sucking the juice from their favorite blossoms while staying aloft in a swirl of vortices. But the unsteady air flows they ...

Biomimetic aerodynamics leverages nature‐inspired design principles to enhance the performance of airfoils, turbine blades and other lifting surfaces. Drawing inspiration from the tubercles on the ...

Staying aloft when hovering and flying slowly is demanding. According to quasi--steady-state aerodynamic theory, slow-flying vertebrates should not be able to generate enough lift to remain aloft.

The researchers saw that the swimmer's downward kick created leading-edge vortices that moved from the front to the back of his feet. After these vortices were shed from the swimmer's body, they ...
