A new study led by Jun Zhang, a Professor at NYU's Courant Institute, determined that hovering in mid-air might actually depend more on weight distribution than once thought. The researchers used pyramid-shaped paper "bugs," which were kept afloat in a stream of blown air. Contrary to common perception about flight stability, the top-heavy structures flew in a more stable fashion than the bottom-heavy ones. The study may offer realistic, new design principles for hovering aircraft and more maneuverable flapping-wing robots.
