	Kaplan turbine - Biocrawler
		The Kaplan turbine was an evolution of the Francis turbine.
		The Kaplan turbine is an inward flow reaction turbine, which means that the working fluid changes pressure as it moves through the turbine and gives up its energy.
		Straflo turbines are axial turbines with the generator outside of the water channel, connected to the periphery of the runner.

		The impulse turbine generally uses the velocity of the water to move the runner and discharges to atmospheric pressure.
		An impulse turbine is generally suitable for high head, low flow applications.
		A cross-flow turbine is drum-shaped and uses an elongated, rectangular-section nozzle directed against curved vanes on a cylindrically shaped runner.

	Kaplan turbine
		A type of turbine, developed around 1915 by the Austrian enginer Viktor Kaplan (1876-1934), that has two or more blades, the pitch of which is adjustable; it resembles a marine propeller.
		The turbine may have gates to control the angle of the fluid flow into the blades.
		Kaplan turbines are well suited to situations in which there is a low head and a large amount of discharge.

	Famous People - Statutory city of Brno
		Kaplan’s life-long interest in harnessing and using the power within water flows is possibly symbolically linked to Kaplan’s place of birth, which was near to the mountain river Würz.
		A model of Kaplan’s experimental turbine in action, its main parts, drawings and photographs formed part of the exhibition which was presented at the Exhibition of Contemporary Culture in Brno in 1928 by the Institute of machine engineering at the Brno German Technical University, of which Professor Viktor Kaplan was the principal.
		Kaplan’s funeral in Unterach was an event for the public, scientists and industrialists alike, and in 1935 he was laid to rest in Rochuspoint.

	TURBINE, (Site not responding. Last check: )
		The basic element in a turbine is a wheel or rotor with paddles, propellers, blades, or buckets arranged on its circumference in such a fashion that the moving fluid exerts a tangential force that turns the wheel and imparts energy to it.
		In addition to these two basic components, turbines are equipped with wheels or drums upon which the blades are mounted, a shaft for these wheels or drums, an outer casing that confines the steam to the area of the turbine proper, and various pieces of auxiliary equipment, including lubrication devices and governors.
		The simplest form of steam turbine is the so-called impulse turbine, in which the turbine jets are fixed in place on the inside of the turbine casing, and the blades are set on the rims of revolving wheels mounted on a central shaft.

	turbine - Encyclopedia.com
		At the inlet end of the turbine high-pressure steam enters from a boiler and moves through the turbine parallel to the shaft, first striking a row of stationary vanes that directs the steam against the first bladed disk at an optimum speed and angle.
		The term gas turbine is usually applied to a unit whose essential components are a compressor, a combustion chamber, and a turbine that resembles a steam turbine.
		The turbine drives the compressor, which feeds high-pressure air into the combustion chamber; there it is mixed with a fuel and burned, providing high-pressure gases to drive the turbine, the gases expanding until their pressure drops to atmospheric pressure.

	Turbines (Site not responding. Last check: )
		The British-born American engineer James B. Francis designed a turbine in which the flow was inward, and the so-called reaction, or Francis, turbine, became the most widely used hydraulic turbine for water pressures, or heads, equivalent to a column of water 10 to 100 m (33 to 330 ft).
		The turbine is designed so that steam entering at one end of the turbine expands through a succession of nozzles until it has lost most of its internal energy.
		In a turbine or compressor, a row of fixed blades and a corresponding row of moving blades attached to a rotor is called a stage.

		Turbines are also divided by their principle way of operating and can be either impulse or reaction turbines.
		The major disadvantage of impulse turbines is that they are mostly unsuitable for low-head sites because of their low specific speeds too great an increase in speed would be required of the transmission to enable coupling to a standard alternator.
		This kind of propeller turbine is known as a fixed blade axial flow turbine because the pitch angle of the rotor blades cannot be changed.

		Broad, swiveling blades on the turbine are spun by high-pressure water as it is released through a sluice, driving the axle of a generator.
		When impulse-type turbines are used, gross head is usually determined as the elevation difference of still water in the forebay and the water jets acting on the Pelton turbine buckets, rather than the still tailwater elevation.
		Impulse turbines have no draft tubes as such, so the drop from the center of the water jets to the tailwater surface is not used to generate power.

	Types of Hydraulic Turbines
		Most of the earlier turbines were so constructed that the water entered their runners at the centre and flowed radially outward.
		The turbine that Francis built following his investigations allowed the water to enter the runner from the outside and to flow inward through the radial blades.
		This type of turbines are similar to Kaplan Turbines, except their shaft position which is not vertical, but either horizontal or inclined.

	Quality Control - 3D Measurement
		So far, 3D scanning of turbines was performed successfully in several hydroelectric power plants in order to assess the condition and the efficiency of these turbines, to check their shape, to create copies or to prepare new ones.
		As for the Pelton turbine, 3D scanning of the Francis turbine's rotor was performed with ATOS and TRITOP.
		For this purpose it was necessary to determine the exact distance to the adjacent blades (angle position), the shape tolerance of the blades and the alignment of the blades with respect to the centerline of the turbine's rotor.

		Kaplan turbine is aimed at very low head sites (down to 2 metres) - in particular existing mill sites which would require very little modification to the existing civil works.
		This spiral cased Kaplan turbine is especially effective in the 20 to 35 metre head range, as site conditions in this range normally have penstocks supplying water to the turbines.
		The high head supplying the turbine means that a high rotational speed of the runner is obtainable and therefore the runner can normally be directly mounted onto an extended generator shaft, giving a higher overall efficiency.

	Statement of Richard K. Fisher, Jr., Salmon Recovery on Columbia and Snake Rivers, Oct. 8, 1998
		The number of turbine runner blades and stay vanes, the length of the fish compared to the size of the turbine, and the quality of the flow at the point of operation are key elements that characterize survival [12,16].
		Specially shaped turbine component geometries were developed for enhancing low pressures at locations for aeration outlets in the turbine water passage, for drawing air into an efficiently absorbed bubble cloud as a natural consequence of the design, and for minimizing power lost as a consequence of aeration.
		Modified Kaplan: Eliminating runner gaps, improved blade shapes and an advanced control system to sense the presence of fish are some modifications to a Kaplan turbine designed by the Voith Hydro, Inc. led team of engineers, biologists and university researchers that may increase survival rates to 98% according to one preliminary study.

	Turbines
		By contrast with the impulse turbine, reaction turbines are difficult to understand and analyze, especially the ones usually met with in practice.
		The principle of a power turbine is to direct the incoming water tangentially by stationary vanes, and then to have it pass to the moving runner where it exerts forces on the runner vanes while its pressure decreases from the input head to zero.
		The runner of a Francis turbine is illustrated at the left.

	Blade for Kaplan turbine - Patent 6007297
		A blade for a Kaplan turbine has substantially linear touching lines for contacting, in the closed position of the guide blade array, adjacent guide blades, the contact lines being linear or curved and running generally parallel to the pivot axis of the blade.
		The objective of the invention is not primarily to improve the already high level of efficiencies of Kaplan turbines with radial inflow and cylindrical guide vanes at design point conditions; rather, the objective is to improve the partial load efficiency and to expand the regulation limits of the flow passing the turbine.
		The usual chaos-regulation for the shaking off leaves, applied on turbines of river power stations, which can cause heavy turbine damage, might be replaced by a smooth reversion of the flow in a turbine according to the invention.
