Bat-drone uses shape-shifting wings to skim over water | New Scientist



Inspired by the way bats change the shape of their wings to control their movement, Robert Bleischwitz
of the University of Southampton, UK, and his colleagues designed thin,
flexible wings that use the same principle. The force of air passing
over the membranes causes vibrations that enhance the drone’s
aerodynamics. “It’s similar to vibrations seen in flags during a storm,”
says Bleischwitz.




During take-off, the drone behaves like a hovercraft as air is forced
below the wing. Once in the air, it can continue to skim across the
water or cruise at greater speeds a metre or so in the air.
