Flying pyramids



Intrinsic Stability of a Body Hovering in an Oscillating Airflow

Bin Liu, Leif Ristroph, Annie Weathers, Stephen Childress, and Jun Zhang
Published February 9, 2012
Synopsis: Floats Like a Pyramid, Physics, APS

"Writing in Physical Review Letters, Bin Liu and co-workers at New York University present results from experiments on an inanimate pyramid-shaped flyer, or “bug.” Their choice of the shape was made in view of previous experiments with tethered flight, which showed that pyramids could hover in an airflow."
