  An aerial vehicle powered by flapping feathered wings was designed, developed
and fabricated. Different from legacy flapping-wing aerial vehicles with
membrane wings, the new design uses authentic bird feathers to fabricate wings.
In field tests, a radio-controlled electric-powered aerial vehicle with
flapping feathered wings successfully took off, flew up to 63.88 s and landed
safely. It was found that flapping feathered wings can generate sufficient
thrust and lift to make a man-made aerial vehicle accomplish takeoff,
sustainable flight and a safe landing.
