Definitions
- the invention relates to a design element for aero- or hydrodynamic components in the form of rotating bodies, flow devices or the like, which mechanically derive energy from a fluid or energy into a fluid.
- the invention relates to a design element for aero- or hydrodynamic components bring in which design element is formed from a flat material blank by spatial deformation.
- the invention seeks to remedy this situation, on the one hand by enriching and improving the development work for aero- or hydrodynamic body shapes with an innovative design element, and on the other hand in certain cases also minimizing the manufacturing costs by means of a manufacturing technique that is largely on one level and therefore Easy to produce blank supports, which only requires a non-cutting and therefore inexpensive deformation in the further shaping.
- the flat blank has the shape of a semicircular surface, which is enclosed by a semicircular line and a diameter, the semicircular line being followed by a semicircular extension from one end with the diameter and the other with the diameter
- the sum of the diameter of the neck and neck is equal to the diameter of the semicircular area, so that the semicircular lines of the neck and neck adjoin one another in an S-shape and that this blank is deformed in space, for example by rolling in, Bending, twisting, edging, dividing, overlapping, connecting, etc., individually or in combination with the same blanks, or blanks that complement one another to form a full circle, and / or one or more complementary supporting bodies, for example Balls or waves, is formed or assembled into the desired component.
- the cut forms a shape which in turn forms half of a circular area and is well known to many places in this shape.
- This material cutting can be inexpensively made in any number of different flat, twistable materials such as Paper, cardboard, plastics, foils, sheets, etc. are produced and brought into those desired spatial shapes by further simple, non-cutting manufacturing steps (twisting, bending, edging, rolling, overlapping, etc.), which can then be seamlessly combined as design elements to form a complex aero- or hydrodynamic component.
- This not only avoids complex manufacturing processes (metal casting, extensive milling processes, etc.) in some cases, it also results in a reduction in the use of materials, which in turn means cost savings but also a reduction in mass and weight.
- 2a is a perspective view of the already rolled (rolled) design elements
- Fig. 3 three of these rotor blades, which are combined to form a rotor (still without a hub)
- 5a a varied pair of blanks with an unequal approach and cutout.
- Figures 1, 1a and 1b show the construction steps for the flat cutting of a design element, which is the basis of the invention.
- Fig. 1 the large semi-circular area (K), which is enclosed by the semi-circular line (b) and the diameter (d) can be seen.
- Fig. La shows the attached to this large semicircular area (K) as a small semicircular area (Hi) with a half the diameter (dj), which starts at the end of the diameter of the large semicircular area and coincides with it, so that the semicircle line (b ) of the large semicircle to the semicircle line (b) of the approach (R).
- Fig. Lb shows the large semicircular area (K) with approach (H **) and the small semicircular area (H 2 ) taken as a detail from the large semicircular area (K).
- Fig. Lc shows the finished shape of a flat blank for a design element.
- this flat cut is twisted through simple manufacturing steps to a targeted spatial design element and in multiple execution by a variety of combination and or variation options to aero- or hydrodynamically shaped components, the actual use of this design element and thus an essential part of the invention.
- the blank (1) is made six times from a flat material. Each of these blanks is formed into that design element by rolling or twisting, as can be seen in a double view in FIG. 2a in a perspective view.
- This non-cutting deformation which is carried out in the same way in all six blanks, to form a combinable design element enables the seamless integration of two of these design elements in the next work step.
- this double-shell rotor blade is manufactured in triplicate and then combined to form a rotor (FIG. 3), the blade roots of the three rotor blades being fixed on an imaginary or real spherical surface with a corresponding diameter in such a way that the rotor blades touch one another without joints and there is only one opening at two points on the spherical surface, each of which corresponds to a triangular shape which is formed by three curved side edges (FIG. 3 - plan view!).
- the centers of these two openings lie exactly on the rotor axis, which can be designed as required and advantageously connected to the rotor.
- this exemplary embodiment represents only one of countless further design options. With some of these possibilities, situations can also arise in which individual cuts or design elements overlap, as shown in FIGS. 4 and 4a as examples. If such an overlap is not desired, it is of course also possible to use only the corresponding cut parts on their own or in combination with the original cut to design further aero- or hydrodynamic components. 4 and 4a, such blank parts (1 'and 1 ") are shown as a hatched area.
- a further enrichment of this invention are the various variations in the shape of the blank itself.
- FIGS. 5 and 5a a case example is shown in FIGS. 5 and 5a, in which the small, forming semicircular lines of the approach and cutout of the two blanks are varied.
- the areas (A ⁇ and A) of these two blanks no longer each represent a half of a circle, but are in the same relationship to each other as the two diameters of the neckline and the cutout.
