Types of Hydropower Turbines | Department of EnergyREACTION TURBINE. A reaction turbine develops power from the combined action of pressure and moving water. The runner is placed directly in the water stream flowing over the blades rather than striking each individually. Reaction turbines are generally used for sites with lower head and higher flows than compared with the impulse turbines.

Turbine - WikipediaShrouded turbine. Many turbine rotor blades have shrouding at the top, which interlocks with that of adjacent blades, to increase damping and thereby reduce blade flutter. In large land-based electricity generation steam turbines, the shrouding is often complemented, especially in the long blades of a low-pressure turbine, with lacing wires.
Detecting Ice on Wind-turbine BladesJul 21, 2011 · Without ice, mass values should be zero. In this case, both turbines have inherent noise of 100 to 150 kg because pitch angle feeds were not provided. Overall system accuracy is maximized by supplying a pitch and angle feed from the turbine controls, along with blade mass and center of gravity.
Gas Turbines: Design and Operating Considerations ...Jul 01, 2015 · The temperature of the turbine blade metal must be monitored to ensure reliability of the first row of turbine blades and other hot sections. The use of pyrometers to sense the blade metal's temperature is offered for some gas-turbine packages for CPI units. Very high pressures in air-axial compressors of gas turbines have caused these ...
