## Description

Well-made

Review: Why nobody mentioned that this engine model is not exact copy of TR900? - Just compare this model with the next description: The Trent 900 is an axial flow, high bypass turbofan with the three coaxial shafts. The 2.95 m (116 in) fan with swept blades is driven by a 5-stage LP turbine, the 8-stage IP compressor and the 6-stage HP compressor are both powered by a single stage turbine...

The machine contains patterns such as connecting rod piston, crankshaft, lever, belt drive, gear drive, worm drive, transmission, threaded fasteners, rolling bearings, sliding bearings, heat transfer, sealing technology, etc.
- low temp stirling engine - Pour 95% alcohol (we recommend this fuel) into the alcohol burner and light it. Let the light burn the round cylinder for about 60-120 seconds, then gently push the wheel, and it will run like magic. With its visual texture and beautiful appearance, it is simply a work of art.
- The hot air Stirling engine can be used as a physics/mechanical demonstration teaching aid, classroom teaching tool and laboratory experimental equipment, gift display, desktop decoration, etc. The Stirling engine is an interesting and imaginative work of art, and is a Christmas and birthday gift for family, friends, teachers, students and technology enthusiasts.
