FR2811380A1 - FLUID ROTOR IN THE FORM OF A SPIRAL GALAXY - Google Patents

Abstract

The invention concerns a spiral galaxy fluid rotor. Said novel rotor is characterised in that it can operate in the reverse direction of a vortex, and it synthesises a propeller and a turbine, through its solid slides mounted on the coiled peripheries of sails or blades, thereby channelling fluids for maximum performance. Said rotor consists of coiled sails, helical and interleaved around a shaft. Said rotor can be used: for reception in wind turbines and run-of-river hydraulic turbines, propelling aircraft, helicopter, boat rotors; in pumps, compressors, ventilators, mixers. Said rotor generates less turbulent flows and noise and reduced cavitation effect.

Description

Principle known since ancient times, Man has always dreamed of

  fly like birds (ICARE) or soar like seeds of

certain trees such as maple.

  Léonard de VINCI designed in 1483 a flying wing (fig. 1) spiral and helical which could be suitable for a rotorcraft. After seeing a balsa model made by a renowned polyhedron builder, Mr. Guy LE BERRE, professor of mathematics

an idea came to me.

  This model (fig. 2) represented a spiral and helical staircase

  built with the proportions of the golden ratio: 3 -

  This conical assembly, suspended from the ceiling by a wire, was rotated by the push of hot air from a small candle lit at its base. The movement generated by this small thrust generated by the

  bougie surprised me, considering the size and the weight of the model.

  I made the connection with the drawing of VINCI and imagined a double helix spiral and helical which can be used to capture the wind or hydraulic force, and again to ensure propulsion, in air (as rotor

  helicopter) or hydraulics for boats.

  From there, was followed the realization of a model (fig. 3) in strong cardboard with two wings, spiral, helical and intertwined. These wings (2,2 ') being

  arranged symmetrically around an axis (1) so as to achieve balancing.

  Each of the wings making a complete turn of the axis.

  This achievement surprised by its rotation speed and its torque

important startup.

  In this rotor with a horizontal axis, the positive effect of the axial thrust exerted by the wind on the rotor, increases as one moves away from the center. So the idea came to me to divert the wind towards the periphery to

get maximum thrust.

  This was made possible by lining the perimeter of the wings with a watertight and spiral slide (4,4 ') serving to contain and guide the fluid. This slide is mounted on the side of the helical top (8) of the wings (top of the rotor). -2- The height of this waterproof slide on the periphery of the wings decreases, from the outside towards the center, or from the periphery of the base (3) to the periphery of the top (8). In this assembly, a spiral bulkhead (5.5 ′), parallel to the axis (1) connects the two wings (2.2j where they overlap, around the edge of a wing in its narrow part (of its top) has the other wing in its broad part and in the middle

  about. This partition creates a vacuum zone in the middle of the rotor: which in no way affects operation and contributes to the solidity of this rotor.

  To reinforce the robustness of this assembly, retaining cables (7) connect the top of the slides to the top of the axis of the rotor (8) and this at regular intervals. At the top of the rotor, (in an upstream assembly), a deflection cone guides the central wind towards the channels formed by the slides, the partitions and the

wings.

  Thus, this rotor holds both the propeller and the turbine. It is an axial feed rotor with tangential escapement. Noise pollution due to exhaust is reduced. The performances of this type of rotor, high torque and speed, hold

  in that the air received is channeled towards the periphery by two spiral and helical channels delimited by the slides (4,4 '), the wings (2, 2') and the partitions (5,5 ').

  The pressure of the captured wind, thus creates an overpressure in these spiral and helical corridors until the tangential ejection (6,6 ') of this compressed air which gives a thrust by reaction) among others, on the opposite slide; which amplifies the already existing torque 25 without these slides and partitions.

  These wings will be built with plates that are both light, thin and robust.

  The downstream (downwind) mounting of this rotor will be preferred given the lesser disadvantage of the supporting pylon for this type of rotor with the advantage of

I'auto-orientation.

  -3- Conversely, in reverse mounting, this same rotor, this time driven by a motor with an appropriate direction of rotation, will catch the fluid through the opening (6) of the existing channel at its base. This fluid will be channeled towards the center thanks to the spiral and helical corridors, thus creating a forced and continuous compression on the top side (8) of the rotor and a depression area on the base side (3), thereby generating an axial thrust.

  in front of the base (3) of the rotor. This latter assembly can be used for propulsion of air and hydraulic vehicles (such as helicopters, boats).

  This rotor looks strangely, by its shape (fig. 5), to galaxies

  spirals very widespread in the universe.

  So very proven form and which gives it an idea of reassuring power.
