Spring Winged Aircraft

Spring winged aircraft described in ScienceNOW, 19 January 2005. Insects use two layers of muscle to flap their wings – as each layer contracts it stretches the other, which then contracts whilst the other layer relaxes and gets stretched ready for the next cycle. This process occurs too quickly to be controlled by nerve impulses, […]
