Metal Helicopter, Stirling Motor Generator, Model, Hot Air Stirling, Power Generator Motor, Physical Experiment for Technology Enthusiasts

Stirling helicopter: it is not only a beautiful helicopter, but is also powered by a ?-shaped Stirling engine. It does not fly, but when you light the alcohol lamp, the propeller turns as if it was ready to go Excellent manufacturing process: the model is drawn by CAD and manufactured using CNC precision technology. The body is made of aluminium alloy and stainless steel, gears and blades are made of copper and the surface is finely polished, exquisite and shiny. The glass bulb has better abrasion resistance and the quartz heating tube does not burst, even if it works in an environment with fast thermal expansion and contraction. How to use: After assembly, put about 2/3 of the alcohol into the alcohol lamp, light the alcohol lamp and place under the heating cylinder for 30 seconds to preheat. To start, turn the flywheel by hand to make the diode light up. Meaning and Value: You can practice your hands-on skills, expand your knowledge of physics, and increase your interest in learning., Manufacturer: ASumPio
