Some Aspects of Performance Improvement of
Pelton Wheel Turbine with Reengineered Blade and Auxiliary Attachments
Suraj Yadav
Abstract- Pelton wheel is the only hydraulic turbine of the impulse type in common use, is named after an American engineer Laste r A Pelton, who contributed much to its development around the year 1880. Therefore this machine is known as Pelton turbine or Pelton wheel. It is an efficient machine particularly suited to high heads, many modifications is being suggested up to now the m ajor modification was near 1903 after that no major modification is being implemented. The author in this paper with his noble and native concept tried to increase the efficiency of the turb ine with the modification in the blade and with some auxiliary attachments which will lead to less wastage of the head and result in better efficiency.
Index Terms— Hydraulic turbine, impulse type, reaction type, camber angle, central bucket design, auxiliary attachments, auxiliary bucket design, gear assembly.

elton wheel turbine is one of the famous turbines which are mostly used for the hydro plants. This is of impulse type and is used for high head, although the efficiency of such turbines are not so comparable with the reaction turbines, because most of the energy is wasted, due to the spli tting of water which is not being utilized and get wasted, due to this efficiency of the turbine is not so as the efficiency of other turbines like axial or reaction turbines. Related to the same context many modifications were suggested for the enhancement of the efficiency but the major change which was adopted or implemented was around 1903 after it there was no further modification were implemented.
So this work is purely intended to enhance the efficiency of the pelton wheel turbine with
