This mini steam turbine engine with deceleration gear set is a finely crafted mechanical model designed for enthusiasts who appreciate precision engineering. It replicates the working principles of a real turbine system and operates smoothly under compressed air tests.

The model features a 1:5.5 reduction ratio, allowing for efficient power transmission and stable performance. The turbine wheel is made of brass and aluminum, ensuring both durability and an authentic metallic appearance. The rotor, also made of brass, has a 41 mm diameter and is supported by two stainless steel bearings for smooth rotation.

The stainless steel spindle (6 mm) ensures long service life, while the oxidized aluminum base provides excellent stability and corrosion resistance. The intake flange structure includes an O-ring seal and is secured with four stainless steel hex screws, ensuring tight and reliable assembly.
