Metal Steam Turbine Engine Model Science Experiment Desktop Engine Model - Enginediy
Features: .Mechanical Crafts: This is a "unique" steam turbine designed with reference to the principles of steam turbines and aircraft engines, combined with the characteristics of low-pressure and low-speed small boilers. .Operating Principle of Machine: A machine that converts the kinetic energy of water vapor into the kinetic energy of the rotor. When the machine is running, it will be very shocking and eye-catching, which is impressive. .Science Educational Toys: This is an interesting and imaginative engine model. You can explore science in the process of playing and observe the magical operation and energy conversion process. .Well-made: Independent start without assistance, high speed, long life and continuous work. Mainly made of metal, it has a beautiful and atmospheric silver appearance. The surface is finely polished to prevent rust and fading. The texture and beauty are excellent. .Product Description: Because the steam pressure of the small boiler is much lower than that of the real machine, the impeller structure used in the model is slightly changed. Theoretically, the thermal efficiency of the steam turbine is 35% higher than that of the piston reciprocating steam engine. But because the pressure of small boilers is very low, and the steam turbine is not forced to do work. Therefore, in the low-pressure and low-speed model world, pistons are better than turbines. .Wide Range of Applications: This is an amazing and wonderful product, suitable as a holiday gift for technology enthusiasts, family, friends, and children. It can be used as a science educational toy to study the working principle of the engine, provide materials for children's science projects, inspire curiosity and creativity, and can also be used as a cool desktop decoration artwork. .Simulate the principle of aircraft engine, support DIY modified generator .For Ages: 8+

Pretty typical Chinese export product. Product resembles description but lower in quality and performance than advertised. Used a pressure cooker (15 psi) for max speed, 3.6k rpm. Had to turn to start due to cheaper internal design. Shaft unbalanced due to sanded flat, not machined. Impulse propeller is bend sheet metal and much coarser. Front fan does nothing but create drag. Overall it was a fun toy to run but not enough power to do anything with.
