Leonardo da Vinci Aerial Screw Helicopter Working Wood Model Kit

One of Leonardo's most iconic images, the Aerial Screw (also known as the Helicopter) illustrates the ingenuity of da Vinci, and indicates (along with many other drawings!) his obsession with flying. While this idea may never have got off the ground, for some basic technical reasons, it gave us an insight into the different ways in which Leonardo considered the challenge of human powered flying, and defines him as an inventor well ahead of his time.While it is often referred to as a helicopter, the premise of the lift to make it rise is more like archimedes screw than the rotors of a helicopter. Our model uses one of the bevel gears he drew in his codices and creates a nice 2 to 1 increase in speed of the crankshaft, so the mast spins quickly, illustrating the manner in which this machine would have worked. All pieces are drilled and pegged for strengthThe canopy and support structure can be removed for experimenting.Lots of interesting information about the way it would have worked too!Stands 38 cm (15 inches) tall and 23 cm (9 inches ) across.Based on the inventor’s drawings from the Codex Atlanticus. This working recreation uses a bevel gear to spin the canopy and support structure, and bring to life the flying machine that Leonardo dreamed was possible.The canopy and support structure of the "helicopter" - designed to be powered by four men (or in this case Lego figurines!) - can be removed for experimenting with your own helicopter or wing-type systems.With accurate historic details, Pathfinder kits are renowned for their clever design and include quality materials.Easy to assemble in approximately an hour, with pre-cut and drilled pieces for super-strong connection. Ideal for beginner model-makers.Teaches principles of mechanics, physics and historical technology. Simple to follow with the help of detailed instructions - young inventors will relish reading about how the aerial screw would have worked.
