Definitions

the invention relates to a cycloidal propeller with wings pivotably mounted on the rotor body in certain vane circle positions and extending transversely to the direction of advance, the rotor axis of rotation and the wing pivot axes running parallel to one another and the adjustment of the vanes being controllable by means of a central control stick via a linkage forming the vane kinematics.
a cycloidal propeller is described in Voith Research and Construction, Issue 18, Article 3, May 67 with the title "The construction of today's Voith-Schneider propels" or also in Voith special edition 9.94 2000. There is also a description of such a cycloidal propeller in the German interpretation DE-AS 21 41 569.
wing kinematics forming the actual wing adjustment are dealt with in detail, so that a detailed description and illustration are omitted here. From the references mentioned, the bearing of the individual blades on the rotor body can also be seen very clearly.
a wing shaft connected to the wing is provided, which is mounted in corresponding bearings, in particular plain bearings.
a double wing can achieve the same lift and induced drag as a single wing with a shorter wing length.
the shorter wing length also brings certain design advantages, since the moment load on the wing bearing is reduced accordingly.
Fig. 1 the vane circle is indicated by 9 and the individual vane positions with a, b, c or d, which are four vane circle positions, thus a four-bladed cycloidal propeller with each four wing pairs 2a, 3a; 2b, 3b; 2c, 3c; as well as 2d and 3d, the wing positions have the same circumferential spacing on the wing circle.
This is common and corresponds to the previous design of a single-bladed cyclo-propeller with four blades according to FIG. 4.
FIG. 2 shows the double wing with its uniform wing shaft 4 in a side view, wing 2a or 3a corresponding in principle to the design of the single-winged, known propeller with wings 12 according to FIG. 4.
Fig. 3 shows the view transverse to the viewing direction of Fig. 2 with the two associated wings 2a and 3a of the pair of wings.
the distance between these two wings of a pair is preferably at least somewhat larger than the maximum thickness of the profile of a wing. The optimal distance must be determined in individual cases.
the position of the wings of a pair of wings with respect to one another can also deviate from the exact parallelism, in particular a certain offset of the two wing profiles with respect to one another can also be carried out.
wing profiles of a pair of wings are designed somewhat differently. It would also be conceivable that not only a pair of wings forming two parallel wings, but three wings or more are used per wing circle position. In general, however, a pair of wings should result in optimal conditions from the overall viewpoint of a hydrodynamic and constructive nature.
FIGS. 5 and 6 A double wing constructed from individual parts, which therefore consists of two parallel single wings, is shown in FIGS. 5 and 6 in the corresponding views.
the common wing shaft 24 carries a base plate 15 which carries the two wings 22 and 23 of a pair of wings. Outdoors There is a connecting plate 13 at the wing end.
the individual plates can be connected to the wings by screws, but also by welding. But the cast version is also a practical version.
the connecting plate at the free wing ends can make a certain contribution to improving the efficiency of the double wing or multiple wing.
the invention can be used not only in cycloidal propellers, but also in wind turbines.
