folding of blades Explanation: For simplicity, the figures are (sic) not shows a device for tightening the spring and - limiters (pins) extreme positions opening and folding blades. https://patents.google.com/patent/RU57385U1/en Для упрощения, на рисунках также не показано устройство для закручивания пружин и - ограничители (штифты) крайних положений раскрытия и свертывания лопастей. https://patents.google.com/patent/RU57385U1/ru cccccc The folding of blades 21 alters the overall geometry of the turbine. As can be seen by comparing FIGs. 2a and 3a, the folding of blades 21 reduces the turbine's exposed cross-section https://www.google.com/patents/CA2734748A1?cl=en |

pitching blades in tangential direction Explanation: When flow rate is high relative velocity of flow will be more axial. So blade should pitch vertically. If flow rate is low, relative velocity of flow is more tangential. So blades are pitched in tangential direction. http://www.learnengineering.org/2013/08/kaplan-turbine-hodro... |
