Nano Cannon Stirling Engine Kit


Nano Cannon Stirling engine

Stirling engines run from just heat, and this beautiful little Gamma engine runs from a tiny flame using the supplied burner. A mechanically simple and elegant design with mesmerising action.

The nano cannon engine runs at blistering 2000 RPM from a tiny flame. Kontax have made a special burner to go with the engine - you just add methylated spirits and light the burner, let the engine heat up, and then give the flywheel a small flick to start the engine.

The entire nano cannon engine was first designed and then simulated in CAD/CAM. Prototypes were then made and tested, parts were then redesigned and prototyped again until the engine was perfected. The engine has special borosilicate glass which can withstand high temperatures enabling you to glimpse inside the engine. A mesmerising Ross yoke links the power piston to the displacer piston; this mechanism is compact, reducing the overall size of the engine. Kontax have utilised a low-friction graphite piston, this is self-lubricating and requires no maintenance. A brass heat sink disperses heat from the cold side, while the rest of the engine is made from anodized aluminium.

What is a Stirling engine and how do they work?

Stirling engines convert a temperature difference into motion. There is a hot side and a cold side to the engine. Provided there is a large enough temperature difference the engine will run. Stirling engines work by cyclically heating and cooling the air inside the main chamber. As the air heats up it expands, and as it cools down it contracts. This expansion and contraction drives a small piston which in turn drives the flywheel. The clever thing about Stirling engines is that the mechanism for cycling the heating and cooling of the air is built into the engine in the form of the displacer, which is driven by the flywheel and moves the air from the warm side to the cool side and back again over and over.The Stirling engine is named after its inventor, Rev. Robert Stirling, who patented his idea in 1816.
