| An ornithopter is a machine designed to fly by the action of flapping wings, as does a bird. Also called flapping-wing machines, ornithopters have captivated the attention of aviation enthusiasts for centuries. The great Italian artist and thinker Leonardo da Vinci envisioned and sketched an ornithopter in the 15th century. Since that time, a number of different ornithopter designs have been developed. | ||||||
