Hot Air Stirling Engine Model Aircraft Propeller Science Experiment Teaching Physics Toy

A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.

The engine is like a steam engine in which all heat of the engine flows in and out through the engine wall.

Rotation speed up to 3700rpm, great for steam lovers.

Through hands-on operation, you can observe the entire process of stirling engine
