Abstract

The invention relates to a method for designing and fabricating bucket turbines with calibrated jets characterised in that the skeletons of the turbines displayed on the screen allow them to be designed and then fabricated in any dimensions, any materials and any quantities, and they are built with blades designed according to the so-called five-parameter arithmetic principle, the skeleton of the turbine is displayed on the screen by means of “virtual neutral fibres” which are subsequently covered with a material, the turbines being contained, over the entire length thereof, in a circular envelope, which is in principle slightly rounded and has a diameter that varies over the length thereof according to the contents of the envelope, and the length of said single-component envelope is shown on a drawing and divided into four zones intersected by temporary virtual discs which each separate the zones according to the functions carried out in these areas, the front edge of said envelope being very sharp or, on demand, provided with a flange Br for allowing connection to installations, the four zones comprising:
