    The invention relates to a device for converting the energy of a flowing medium into a rotational movement with a rotatably mounted base body wherein the axis of rotation of the base body extends approximately normal to the direction of flow and wherein the base body is provided with a blade arrangement.
    Devices for converting the energy of a flowing medium into a rotational movement such as wind wheels, water wheels and the like have been incorporated into the patent literature in various embodiments.
    For example, DE 1 982 6475 A1 discloses a device for converting mechanical energy contained in wind into electrical energy with a device for converting the wind energy into a rotational movement and a dynamo device with a rotor and a stator for converting the rotational movement into electrical energy An inlet includes a plurality of cowls disposed equidistantly from a rotor driving perpendicular to the wind direction axis, a portion of the cowls being movable in one direction with the wind and another portion of the cowls being movable in a direction against the wind; a device is provided which causes the effective wind resistance of those windscreen areas, which are moved in a direction against the wind, is reduced.
    Furthermore, windmills are known for some time, the axis of rotation corresponds approximately to the wind direction and the rotor blades can convert by Schrägs'ellung the energy of the flowing medium in a rotational movement.
    Furthermore, wheels for converting the energy of moving water, e.g. oversized, mid-level or undershot waterwheels to Pelton, Francis or Kaplan turbines known.
    A disadvantage of many of the prior art devices is that they are designed only for a very narrow mass flow range. Outside this range, the efficiency of the energy conversion drops sharply. To counteract this negative effect, there are basically two options.
    One possibility is the regulation of the flowing medium through guide plates, guide flaps, locks or diffuser devices. -2- • ·
    The other possibility is the change of the blade geometry and the orientation of the blades to the flow direction of the medium.
    Such variable devices have the disadvantage that they are expensive to manufacture, expensive to maintain and thus often not profitable in practice.
    The object of the invention is to provide a device for the implementation of the energy of a flowing medium in a rotary motion, which has a high efficiency, this efficiency over a wide mass flow spectrum retains and which is simple and inexpensive in construction, Wa'tung and operation ,
    The object of the invention is achieved in that at least one blade assembly is arranged on the base body, which comprises a plurality of along a curved center line slats and wherein the lamellae have a curvature, the vertices point in the direction of rotation. Further advantageous features of the invention are described in the claims, the description and the drawings.
    In further consequence, the invention will be further described with reference to some schematic embodiments:
    Fig. 1 shows a schematic representation of an embodiment of the device according to the invention.
    Fig. 2 shows the same embodiment as Fig. 1 with drawn construction lines.
    Fig. 3 shows an embodiment with partial masking and three
    Vane assemblies.

    Fig. 5 shows another embodiment with masking.
    1 shows a device for converting the energy of a flowing medium into a rotary movement, with a base body 1 which is mounted rotatably about the rotation axis 2. In the figures, the decrease of the rotational movement and the conversion of rotational energy into usable energy such as electricity are not shown. The axis of rotation 2 runs in this view projecting and is approximately normal to • * k * * · · · »ι * • · · ·» -3
    Direction of flow 3 of the flowing medium 4. An output shaft 24 is shown.
    The flowing medium 4, such as wind or flowing water of a river, is assumed in this embodiment as parallel flow. The flow can also be focused by baffles or similar devices. It may be the entire surface of the body and the device in total surrounded by the medium. In the case of a river power plant, however, the basic body may also be partially immersed, similar to a waterwheel. The direction of the axis of rotation (2) can be arranged vertically or horizontally, but also occupy all intermediate positions.
    Slats 5 are provided on the main body 1, which rise in a prismatic shape approximately parallel to the axis of rotation 2 from the main body 1 or are provided on this. The lamellae 5 have a curvature, wherein the curvature has a vertex 6, which points in the direction of rotation 7 of the main body 1 in an advantageous manner. The lamellae are arranged along an arcuate center line 8, which extends from an inner, ie Drehachs-close, bent position outwards. The lamellae 5 arranged successively along the center line together form a blade arrangement 9 which has an inflow point 10, an end region 11, an inner contour 12 and an outer contour 13. The inflow point corresponds to the point at which the relative velocity of the medium 4 to the base body 1 under the influence of the medium flow and the rotation of the base body is equal to or approximately zero. At this point, the flow separates into two flows, with the inner flow following the inner contour 12 and the outer flow following the outer contour 13. Advantageously, the outer and inner contour 12, 13 form an airfoil-shaped envelope, wherein the inner contour 12 is shorter than the outer contour 13. Favored by this geometric configuration arises upon rotation of the blade assembly about the axis of rotation 2 along the outer contour of a suppression and along the inner contour an overpressure. It should be noted that the airfoil shape is only partially formed by the slats 5. Between the slats 5, the contour is given by the medium itself, similar to a Rankine vertebra or Rankine body. The lamellae 5 themselves are, as mentioned above, curved, with the thickness of the lamellae 5 decreasing in this embodiment to the lateral ends. The lamellae also have a * * · * * · -4 -
    Slat width 14, which in the described embodiment along a radial straight line, starting from the axis of rotation 2 has its maximum width.
    2, the detailed processes for converting the flow energy of the medium 4 into a rotational movement of the base body 1 about the rotation axis 2 will be described below.
    For this purpose, the main body is divided into four quadrants: Quadrant I 15, Quadrant II 16, Quadrant II117 and Quadrant IV 18.
    In principle, the movement of the wheel takes place in that a force acts on the base body 1 at a certain distance from the rotation axis 2 and thus generates a torque. These forces are, for example, dynamic pressure forces, impulse forces due to deflection of a mass flow, Bernoullian compressive forces due to the flow around an asymmetric airfoil profile, but also media resistance forces, which can be varied depending on the medium resistance coefficient and the impacted surface, etc.
    Depending on the direction of flow, flow rate, i. Speed and mass flow of the flow, geometric location on the body, rotational speed of the body, geometry of the lamellae or blade arrangements, the different types of forces come to bear different degrees.
    In quadrant I 15, the fins to a large extent with their inner concave side in the direction of flow direction 3 of the flowing medium 4. The fins are, as noted above, arranged along the center line 8 on the base body 2. By juxtaposing the slats flow channels 19 are formed between the slats. These each have an inlet 21 on the outer side and an outlet 20 on the inner side. If the blade arrangement 9 and its lamellae 5 flow, the flow in the flow channels 19 is diverted so that the momentum of the flow is transferred to the base body 1 when the direction of flow changes. Advantageously, the direction of the force that is caused by the diversion of the mass flow of the medium, approximately coinciding with the direction of the tangent 22 in the region of the flow channel relative to the axis of rotation 2. It can therefore be said that the inlet angle of the flow related on the tangent 22 in approximately the exit angle of the flow of ······· 5 corresponds to the flow channel 19 with respect to the tangent 22. However, it may also be advantageous to choose the exit angle such that a portion of the mass flow is directed into the center of the body to meet with sufficient residual pulse on the opposite side of the body 1 and thus to another blade assembly and the lamellae , If inlet 21 and outlet 20 have been previously described, then note the following: As the wheel continues to rotate, there comes a point where the fins are flown in from the other side or the flow between two fins reverses. Thus, the entrance to the exit and the exit to the entrance can be.
    With varying mass flow of the medium, the pulse can be converted by the diversion in different ways. As fully converted, the momentum of the flow, if the absolute flow velocity at the outlet 20 of the flow channel 19 corresponds to the rotational speed of the body at this location, which is considered otherwise the relative velocity between the flowing medium and the body at least one point of the body is equal to zero. At low mass flow or low speed, it may be that the energy of the flow is already destroyed by the diversion in the flow channel 19 and the dynamic pressure occurring in the convex region of the fins and transferred to the base body 2 in the form of momentum and pressure forces. With a larger mass flow and higher speed, it may also happen that the flow is not completely decelerated by the diversion in the channel 19 and thus exits the outlet 20 and subsequently encounters the lamellae of the opposite blade arrangement. There, the flow can in turn enter the channel 19 and convert by a repeated deflection the remaining momentum into a torque about the rotation axis 2 of the base body 1. For this purpose, it may be advantageous to choose the exit angle of the outlet 20 in such a way that, with respect to the direction of the tangent 22, it is larger and thus exits a steeper direction of rotation axis 2. Further, the cross section of the exit 20 and the cross section of the entrance 21 may have a different size, e.g. to achieve a nozzle effect.
    A further effect which results from the special arrangement of the lamellae and the blade arrangements is that in the region of the axis of rotation 2, the velocity of the flowing medium 4 is very low, since this area is covered by the blade arrangements in almost all rotational days. The outer region of the * I * * * * * * * + * * * t * t *% * * * * * * * * * * ρ ψ ι »ι * ··· - 6
    Blade arrangements, in particular the outer contour, however, flow through the rotation of the basic body almost at any time, at least at the speed of the rotation. Only by this difference in speed buoyancy forces, which is converted into a torque by the oblique or outwardly spiraling configuration of the blade assemblies.
    In the quadrant II, the lamellae 5 of the blade arrangement 9 are in a position in which the flow of the medium 4 experiences a high resistance to the passage of the channels 19. This is because, due to the crescent-shaped design of the lamellae and the rotational position of the basic body, it is not the inlet openings of the flow channels that point in the direction of flow, but rather the lateral surfaces of the lamellae. Furthermore, by the rotation of the main body about the axis of rotation 2, a media flow around the blade assembly is formed, which also makes it difficult for transverse flows to flow through the blades. In this region, the end portion 11 of the blade assembly 9 acts like a sail or an inflicted surface. The flow strikes this surface, which is to be regarded as being almost airtight, whereby a back pressure arises which, combined with the flowed-on surface, generates a force which in turn causes a torque by its normal distance from the axis of rotation 2 of the main body 1.
    In the quadrant III 17 and VI 18 now has the vertex 6 of the blade assembly against the direction of flow 3 of the medium 4. Due to the crescent-shaped design of the lamella, the flow in the region of this vertex divides into two flows, the one flow flows along the outer contour 13 along and the other flow along the inner contour 12 extends. Advantageously, by forming an airfoil-shaped structure, the length of the outer contour is greater than the length of the inner contour, whereby on the outside of the blade assembly, a negative pressure and on the inside of the blade assembly creates an overpressure. Because the contour of the blade arrangement is bent or spirally outwards, these pressure forces (buoyancy forces) can also be converted into a torque about the axis of rotation 2. It should be noted that the wing profile results partly from the shape of the individual slats, but partly also from medium flows. Thus, as noted above, in the area of the flow channels, the airfoil profile is similar to a Rankine vortex or a Rankine body. In the quadrants III 17 and VI 18, the direction of the -7- • · · -7- • · • »» * · · ·
    Movement of the blade assembly directed against the direction of flow of the medium 4. Since, however, the fins from the front, ie the direction of the vertex, have a lower coefficient of resistance than in quadrant I, where they are flowed from behind, this force affects the efficiency only slightly. 5
    In order to minimize this resistance, as shown in Fig. 3 and 5, a cover of the quadrant III and IV are made. FIG. 3 shows a base body 1 mounted about an axis of rotation 2, wherein the left side and thus rotating against the direction of flow 3 is covered with a masking 22. Further, unlike the configurations of FIGS. 1 and 2, three blade assemblies are provided. These blade arrangements also each consist of lamellae 8, which are arranged along a, spirally outwardly extending contour.
    Fig. 4 also shows schematically a plan view of a base body 1, which is arranged rotatably about a rotation axis 2, wherein from the base prism-shaped, approximately parallel to the axis of rotation 2 lamellae 5, which along a contour 8 extending a blade assembly 9 result , In this embodiment, four such blade assemblies 9 are arranged. The provision of a plurality of blade arrangements further flow effects occur: In addition to the above-described pressure, momentum and Bernoulli forces also recoil forces occur in this case. If one looks at a selected current thread 23, it enters between two blade arrangements, subsequently runs through a flow channel 19 and exits again on the outside of the flow channel. By selective choice of the inlet and outlet cross sections of the flow channels 25 of this nozzle effect can be further optimized to generate additional torque.
    In Fig. 5, the masking 22 is provided as a flow-guiding inlet mask, which directs the flowing medium 4 without disturbing turbulence on the quadrants I and II 30. Abströmlamellen 25 are arranged in the outflow region of the device, which are arranged stationary with the masking 22, so do not rotate with the main body. For example, the bearing of the rotatable base body and optionally the attachment of the masking and the Abströmlamellen be given on a platform arranged in the flow of the medium. An advantageous arrangement for a waterwheel can also be the arrangement on a pontoon that floats in the water. For training as a wind turbine, it may be advantageous to use the * * * * -8-
    Device to be rotatable or pivotable about an axis to accommodate the wind direction. The rotatability of the masking and possibly the Abströmlamellen may be sufficient for the effect. 5
