It is an axial flow reaction turbine. This operates in an entirely closed conduit to tailrace. Kaplan turbine is employed, where a large quantity of water is available. It consists of spiral casing, guide mechanism and draft tube of Kaplan turbine runner are similar to those of Francis turbine.
Custom Kaplan turbines are used primarily for lower heads and larger flows. Voith also supplies cost-effective Kaplan units in standardized designs for small er hydropower plants. 1870 Hydro turbine manufacture began. 1916 Development of Voith Kaplan model turbine. 1922 First prototype Kaplan turbine, Austria.
The Kaplan turbine is a reaction type which is suitable for low pressure hydropower plants and can be used with big discharges. The Kaplan runner, similar to the Francis runner, also should be submerged in the water for proper operation.
In this paper, the generator power is 50kW and the water head is 8m. In Kaplan turbine design, the runner radius is 228.25mm, the runner speed is 826.12rpm, number of runner is four and the number of guide vane is eleven.
The Kaplan turbine is an important type of water turbines in hydroelectric power plants. It ranks third behind the Pelton and Francis turbines. The three turbines share the properties that they all can be well designed, manufactured and operated for high hydraulic performances, based on developments and experiences over the past 100 years.

Kaplan Turbines
Kaplan Turbine was developed by the Austrian en-gineer Victor Kaplan towards the beginning of the 20th century. Due to its adjustable runner blades this turbine system is most adaptive. Apart from the ori-ginal version with vertical shaft and inlet spiral case the bulb turbine variant has spread widely over the world. Principle

This short note indicates how a preliminary design of an axail flow Kaplan turbine can be carried out - see Figure 1 for a cross section of the device. Note that this analysis is approximate and is useful for a first appoximation only. In order to carry out a preliminary blade analysis consider a mean radius through the machine.
