The unit is for demonstration of stirling cycle hot air engine.
The engine consists of two cylinders. The first (displacer) cylinder is made of Pyrex glass and is to generate hot air by a resistance heater. The second (power) cylinder is to generate a mechanical power on a fly wheel by hot air from the first cylinder. Air flow passage and phase angle between the two cylinders are such that the expanded cool air from the second cylinder is returned for heating in the first cylinder. The power to the heater can be varied. Cylinder ports allow engine to operated on gasses other than air. Instruments are provided for measurement of input power, and output power.
