Stirling Cycle Hot Air Engine Twin Power

The engine consists of a large vertical cylinder with heater to generate hot gas. Twin cylinders above the hot gas cylinder generate power. The hot gas cylinder head can be cooled by water from a cooling system. The Stirling Cycle Hot Air Engine Twin Power unit is for demonstration of stirling cycle hot air engine principles. All cylinders are attached to a common shaft. Heater to the hot gas cylinder can be varied. The advantage of this design is the ability to bring the engine to operating condition in a short time. Instruments are provided for measurement of input power and output power. 

Experiments:
Output and efficiency vs speed for a given input power.
Torque vs speed for a given input power.
ffect of hot gas cylinder head cooling on efficiency.
