One of basic elements of so-called steam-turbine installation is the turbine. It is the heat engine supplied with shovels during which operation the energy of the heated and compressed steam turns into the kinetic energy forcing to turn a shaft. The working model of the steam turbine can be made the hands of available materials.
It is required to you
- - can;

- - scissors for metal cutting;
- - chertilka;
- - nippers;
- - hammer;
- - emery paper;
- - drill;
- - drill;
- - soldering iron;
- - soldering liquid;
- - solder.
Instruction
1. Prepare a can which will play a boiler role. Make sure that bank it is intact and has no damages. Process edge passatizham banks that on them there is no hangnail left.
2. Cut out from a piece of thin tin a circle on diameter banks. One more circle is required for production of the turbine; at the same time its size will be defined by the sizes of all design.
3. Cut off a piece of an aluminum wire and make of it a nozzle. Its length has to be about 15 mm, and diameter – about 0.5-0.7 mm.
4. In a tin cover drill two openings. The first is required for fastening of a nozzle, and in the second you will fill in liquid. For convenience of installation of a design execute a jellied opening closer to edge of a cover.
5. Smooth out a surface of a cover and edge banks an emery paper. Now solder a nozzle and a nut by means of which the turbine will fasten to a cover. A ready cover also by means of soldering attach banks to the case. For connection of aluminum details use special gumboil or soldering liquid.
6. Manufacture the turbine. For this purpose divide the circle which is previously cut out from tin a metal chertilka into six equal parts, and then consistently also halve each part. At you twelve blades, however their quantity have to turn out you can make other.
7. The turned-out petals of the turbine turn in passatizham to a half of radius. In the center of the turbine make an opening and solder to it a head part of an aluminum rivet.
8. The holder for the turbine execute in the form of a curved plate. At the same time width of the holder has to exceed length of two rivets. Solder the turbine to the turned-out holder, having provided it at the same time an opportunity to rotate freely on an axis.
9. The holder equipped with the turbine seal in a cover directly over a nozzle. Surely make sure at installation that the turbine does not touch other details of a design. Now turbine installation is ready to demonstration of the opportunities.
10. Accurately pour in water that it occupied no more than a half of a copper in a jellied opening. Cork an opening. Use a spirit-lamp or a usual stearin candle for heating of a copper. When water begins to boil, the water vapor which is under pressure will bring the turbine into rotation.
