Stirling Engine Helicopter Model, Miniature Air Energy Physics Engine Toy, Science Experiment Educational Display, Heat Engine Demonstrator,

This Stirling engine helicopter model demonstrates the conversion of heat energy into mechanical motion. Powered by a small alcohol lamp, the engine uses the Stirling cycle to drive the propeller, providing a visual representation of thermodynamics. The transparent acrylic base allows clear observation of the internal mechanism. Ideal for science classrooms, physics demonstrations, and educational displays. Suitable for ages 14 and up.
