    • 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:
      a first zone for (1) for injecting the fluid, which is an empty space or a space containing valves or inducers, of the corkscrew type, which optionally cause a pre-rotation of the fluid which enters a second zone (2), a pointed shield pushing the flow of fluid away from the centre on arrival, and directing it away towards the second zone (2), the second zone (2) where the rotation of the fluid is created in channels that wind in spirals and open up at the rear of the second zone (2), rotating the fluid, a third zone (3) containing the rotating wheel provided with buckets with calibrated jets that harness the energy supplied by the jets of fluid leaving the second zone (2), and a fourth zone (4) containing a housing attached to the stationary casing of the turbine and placed after the rotating wheel, said housing containing channels that orient the fluid towards the outlet at the rear of the turbine, and the fluid is guided, as soon as it reaches the second zone (2), by channels contained in tubes that are arranged in continuity face to face, over the entire length of the turbine.
