Going with the Flow
Given a sequence of poses of a body we study the motion resulting when the body is
immersed in a (possibly) moving, incompressible medium. With the poses given, say, by an …

Experimental study into the effects of pitch and coning angles on the flight performance of the natural samara
BK Jung, D Rezgui - Royal Society Open Science, 2024 - royalsocietypublishing.org
Using their light wing and through the use of a leading-edge vortex (LEV), autorotating
samaras can generate high lift while descending at extremely low speeds. But the flight …
