Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Gorlov Is a water turbine evolved from the Darrieus turbine design by altering it to have helical blades/foils. … Most commercial turbines are small and micro in size. Small hydropower turbine design produces less than 1MW of power while the microturbines produce 100 kW or less. The typical small hydroelectric turbine design powers around 1000 homes while microsystems can power 100 homes or even one home. Hydropower Turbine Design It is intended to elaborate standardized design for this type of turbine. Innovation is claimed for performance with no direct contact of oil and water-method parts with the turbined river water, for maintenance-free bearings and for the elaboration of a standardized design.
A Kaplan turbine designed with a shape factor (power specific speed) of 3.0 (rad), a runner tip diameter of 4.4 m, and a hub diameter of 2.0 m, operates with a net head of 20 m and a shaft speed of 150 rev/min.

A Kaplan turbine is a type of propeller hydro turbine (specifically a reaction turbine) used in hydroelectric plants.Water flows both in and out of Kaplan turbines along its rotational axis ().What makes Kaplan turbines special is the blades can change their angle on demand to maintain maximum efficiency for different flow rates of water.

Learn new and interesting things. Get ideas for your own presentations. Share yours for free! I need someone to do assembly and working drawings of something like the kaplan turbine and generator in the link above.
This turbine was developed in the year 1913 by Viktor Kaplan, who was a Austrian Professor. In his design, he combined automatically adjusted propeller blades and automatically adjusted wicket gates to obtain efficiency over a wide range of water flow and water level. The process of the Kaplan turbine design is used as an example in this paper.
