Flying fish

摘要

Billions of years of evolution have resulted in a wealth of biological systems and forms that continue to be a source of inspiration for engineers. From the bone-inspired Eiffel Tower to the sharkskin-mimicking swimsuit, nature, it seems, often holds the definitive blueprint for improving man-made designs.rnWhen it comes to objects that move in the air, birds have been the classic model for forward-thinking engineering. The wing movement of a swift has inspired research into morphing wings, while the V-shaped formation of bird flight has been taken up for more efficient formation flight by air forces.
