Phywe's transparent Stirling engine clearly shows the engine's components and operation. For the demonstration of the function of.

• Hot air engine.
• Heat pump / cooling machine.
• Solar motor

For determination of: Mechanical and electrical power as a function of speed. Operating temperatures and temperature differences. Efficiency. For measurement and evaluation of pV diagrams.

Stirling engine, transparent: Stirling engine mounted on lacquered base plate. Large transparent flywheel. Cylinder and piston of heat-resistant glass. Crankshaft and shaft made of durable plastic. Ball bearing suspended shaft in hardened steel. The piston has two connection points for temperature measurement.

Bottom plate: 207 × 290 mm, Flywheel: diameter 140 mm, Motor power: t approx. 1 W, Rotation speed without load min. 800 rpm. Standard accessories: Alcohol burner and Allen key for mounting flywheels. Motor / generator unit: To convert mechanical energy from the Stirling engine to electrical energy and to drive the Stirling engine when used as a heat pump or cooling unit. Motor shaft with pulleys in two different sizes. Base for light bulb E 10. Connectors for connection of power supply (max. 12 V DC). Standard accessories: Drive belt. Light bulb: E 10, 4 V / 0.04 A.

Torque wave: For direct determination of the mechanical energy generated by the Stirling engine. Adjustable friction and a scale. The pointer is mounted on the shaft of the Stirling engine and the scale on the base plate. Measuring range: 25 × 10-3 Nm, Resolution: 1 × 10-3 Nm, Chimney for Stirling engine. Place on the spirit burner to obtain even heating of the Stirling engine for long measuring periods. Made of heat-resistant glass. Accessory kit for solar operation: To power the Stirling engine with solar energy, an accessory kit consisting of a parabolic mirror, holder for mirror, small flywheel and black collecting ring is needed. pVnT measuring instrument for Stirling engine. For display of temperature and speed as well as analog voltage output for pressure and volume to the oscilloscope. 4 digit display.
