UAV with Wings that Morph Like a Bird

Birds have honed their ability to fly and radically change, or "morph", the geometry of their wings over millions of years of evolution. Now aircraft inspired by the "technology of nature" stand to reap enormous benefits, thanks to researchers at Blue Bear, who have designed, developed and flight tested a unique bird-like wing on a small Unmanned Air Vehicle (UAV). The morphing wing has already shown big benefits in terms of improving the aircraft's energy consumption, its stability even in gusting winds, and an increase in the range of speeds at which it can fly. The use of Additive Layer Manufacturing techniques has also allowed Blue Bear's designers to take on some of the structural lessons from birds.
