DESCRIPTION:
BRIEF SUMMARY
The invention relates to the design of a tri-monolithic wind motor module including a turbine wherein the laminar character of the air flow is aided by a parabolic trajectory based on appropriate redesigning.
In accordance with the state of the art and French Patent No. 2,509,801 and 2,556,783 relating to a wind motor module and a tri-functional turbine, all wind machines generate turbulences and vibrations which impair efficiency and reliability. Furthermore, machining and assembling a plurality of basic components considerably reduces the competitiveness of the product.
The present invention is depicted in the attached Figures, wherein:
FIG. 1 is a cross-sectional view of the present invention;
FIG. 2 is a sectional view taken along line A-B in FIG. 1;
FIG. 3 is a sectional view taken along line C-D in FIG. 1; and
FIG. 4 illustrates the parabolic course imparted to the airflow by the device of FIG. 1.
It is an object of the present invention to remedy this state of affairs by means of a total redesign, characterized by combining in a single operation just three monolithic blocks comprising a turbine 1, a base 2 and a hemi-lenticular dome 3, FIG. 1 (vertical section).
Thus, the turbine 1, FIG. 2 (Section AB of FIG. 1) is comprised of a body 4 in the shape of a truncated cone joining together at the time of casting the peripheral assembly of vertical blades 5 which are uniformly distributed over the exterior surface.
Each one of these recti-curvilinear blades has a rectilinear portion extending beyond the exterior end of a curved portion. The rectilinear portion, extending outward from the exterior edge of the disk 6, forms an angle of 30.degree. with the axis of the turning circle of the center 0. Said disk, of one piece with a skirt 7 of the truncated cone-shaped body is also of one piece, having at its center a central shaft 8. This shaft, arising from a subjacent base, can operate any working accessory.
But also, when the electrical function is desired, the interior portion of the truncated cone-shaped body can be equipped with a soft-iron ring, on which ferrites are glued facing windings wound on solid laminated armatures of a subjacent base.
The base 2, FIG. 3 (section CD of FIG. 1) has in its center an opening 9 with opposed abutments 10 and 11 in which the shaft of the turbine pivots. Furthermore, the base has around its periphery a series of vertical wings 12 which create not only engagement or escape channels but channel and direct the flow of air towards the extension of the curved end of each blade corresponding to the point of interaction a.
Thus, when the wings perform a movement action, the engagement channels, the blades and the skirt of the truncated cone-shaped body together, not separately, contribute to the movement effect but also to the creation of an internal rising flow which tangentially meets the truncated cone-shaped internal cavity 13 of the hemi-lenticular dome 3.
This hemi-lenticular dome has on its internal cavity a convex section 13 of small spread and on its exterior surface a convex section 14 of large spread, surmounted by a protuberance 15, also in the shape of a truncated cone. This hemi-lenticular dome, placed over the turbine and the base, bends the air flow by imparting to it a descending curve. This air flow thus is bent near the top b of the rectilinear portion of the blades with an incidence of 20.degree. to 30.degree., where it exerts a complimentary moving effect. Then the said flow continues by blowing against the curved parts of the blades from where it escapes in the inverse direction of the turbine having the effect of the reaction c. Consequently, during each revolution of the turbine, each one of the blades is subjected to three effects: a main action at the point of interaction a, a complementary action at the top b of said blades and an exit reaction c, according to the illustration of the parabolic course defined by FIG. 4, where the marking plane of the curve is inclined by 30.degree. to the horizontal rotational plane of the turbine.
