Build Your Own Model Nitinol Engine Scientific Construction Kit
Curious Minds Did You Know: Nitinol is an alloy of titanium and Nickel and is super elastic, it also has shape memory properties which means it can return to its original shape when heated.
The heart of this unusual thermal engine is a thin ring of Nitinol wire (0.3mm). Some warm water is enough to make the Nitinol Engine run. Nitinol is an alloy of nickel and titanium which has exceptional properties: at low temperatures it is soft and bendy, but as soon as it is heated above a certain transition temperature, it instantly becomes hard and flexible like spring steel. As soon as the temperature drops again, it returns to its bendy state. Nitinol is also a so-called memory metal: above the transition temperature it instantly assumes any shape that has been impressed during manufacture.
The transition temperature of our wire ring is 45ºC above which it becomes stiff and straight. Nevertheless the part of the wire that is immersed in the warm water lies around the drive wheel. When it straightens out, it is forced to move off the wheel and out of the water where it becomes bendy again. At the same time it pulls a new piece of wire into the water and the process starts again, leading to a constant rotation of the drive wheel.
The principle of this engine was developed by Frederic Wang in 1985. It works with only a small temperature difference and shows great potential for future applications.
This AstroMedia kit is the first mass-produced engine of its type, worldwide. Anybody interested in engineering and physics will be fascinated by this kit. A fantastic model and a great present!
Pre-punched cardboard kit, includes Nitinol wire ring, aluminium shafts, PVC bearings, wooden axles, plastic drive wheel and running wheel, etc.
Size: 140 x 166 x 213 mm
