Definitions

  • Actinic fluid drive is the drive system in which at least one circular wing (11) is located in a main actinic flow (15) whose direction (plane) at the leading edge of the circular wing (11) with the chord forms the angle of attack ( ⁇ ), which is greater than 0 and less than 90 degrees - especially greater than 8 degrees - and the actinic Ha-
  • the main flow reduces the pressure across the top of the wing (the wing bottom is either flowless or closed) and due to the 50th pitch angle ( ⁇ ) and the increased ambient pressure (fluid pressure above the main flow height) is tilted analogously to angle of attack ( ⁇ ) (Coanda effect), thrust is generated and the flow is laminar.
  • the AF can be provided with a circular conductor (13), which includes the trailing edge of the last circular wing (11) (circular wing deck & base shape) and the main flow (15) in the suction of a radial impeller (12) and they at the front edge 10th of the first circular wing (11) again leads (recycle).
  • the closed Actinic Fluid Drive (GAF) is one of the safest, both for the guidance system and for the functional environment ( Figure 4).
  • the AF can replace the propeller in any relative applications and also reduce the form resisting force (e.g., rockets, ship's bulge, aircraft spikes, hub, etc.).
  • the AF can e.g. as: blower, fan, two-phase pump, forward or boost generator (water-air propeller), reppeler (generate mechanical power from a flow) and act as actinic wing profile duct measuring system.
  • Sketch 1 shows the section of a circular wing (11).
  • FIG. Sketch 2 shows the section of an open actinic fluid drive (OAF) (fresh fluid 30th in the system).
  • OAF open actinic fluid drive
  • Figure 7 shows the section of a GAF that can work both as a two-phase jet pump and as a repeller.

Abstract

L'invention concerne un entraînement fluidique actinique (radial) (AF) capable de remplacer une hélice dans tous types d'applications d'hélices, par ex. dans une soufflerie, un ventilateur, une pompe, une centrale hydraulique ou une éolienne (réflecteur), un véhicule marin et un aérostat (bateau, hélicoptère etc.), et de réduire la traînée due à la forme (pointe de fusée, étrave à bulbe de bateau etc). Ledit entraînement fluidique actinique est caractérisé en ce qu'il comporte a) au moins une aile circulaire (11) (aile annulaire), telle qu'un cône tronqué, dont l'arête avant et l'arête arrière (correspondant à la surface supérieure et à la surface de base d'un cône tronqué) déterminent la profondeur d'aile de l'aile circulaire (11) (longueur latérale linéaire), formant, avec le plan de la surface supérieure, l'angle d'inclinaison (f) de l'aile circulaire; et b) un écoulement principal actinique (15) dont la direction (plan) forme, sur l'arête avant de l'aile circulaire (11), un angle d'attaque (?) avec la profondeur d'aile, supérieur à 0 et inférieur à 90°, notamment supérieur à 8°, l'écoulement principal actinique (15) (selon l'effet de Coanda) étant incliné de façon analogique à l'angle d'attaque (?) (production de poussée).
