Blades and vanes for steam and gas turbines, reverse-engineered (no drawings available)
The purpose of turbine blades is to convert the potential energy of compressed steam into mechanical work. Depending on the operating conditions in the turbine, the length of its working blades can vary from several tens to one and a half thousand millimetres. On the rotor, the blades are located in steps, with a gradual increase in length, and a change in the shape of the surface. At each stage, the blades of the same length are located radially to the rotor axis. That is due to the dependence on parameters such as flow, volume and pressure.
A gas-turbine engine has both compressor blades and turbine blades. The principle of operation of such an engine is compression of the air necessary for combustion with the help of turbocompressor blades, direction of this air into the combustion chamber, and when it ignites with the fuel, mechanical work of combustion products on the blades of the turbine located on the same shaft with the compressor. That is the difference between the gas-turbine engine and any other machine having either compressor forcing blades, as in all kinds of blowers, or turbine blades, as in steam turbine power units or hydroelectric power plants.
