Leonardo da Vinci is best known for his ornithopters, helical air screw, parachute, self-supporting bridge, and giant crossbow, but did you know he sketched an aircraft-like object back in 1480? Engineers from University of Maryland decided to turn these sketches into a real flying machine, called the “Crimson Spin”. It’s essentially a quadcopter that has screw-like propellers instead of the traditional ones.
The four corkscrew-like plastic wings are powered by batteries and electric motors, relying on small changes to propeller speed to tilt in various directions. Does the design look familiar? If so, that’s because it’s based on the Archimedes screw, which refers to a machine used for transferring water from a low-lying body of water into irrigation ditches.
