Definitions

  • the invention relates to an arrangement of a ship's propeller and a downstream, freely rotatably mounted stator, the number of blades of which is greater, the rotational speed is smaller and the pitch is greater than that of the propeller, the blades of the stator being turbine-blade-like within the propeller jet and propeller-like outside the propeller jet are trained and revolve around the propeller and stator in the same direction.
  • the object of the invention is to provide an arrangement of the type described in the introduction which is favorable with regard to optimization.
  • the hydrodynamic properties of the propeller or the stator are determined by the pitch distribution of the radial wing sections.
  • a steady, in particular essentially linear, gradient distribution in the direction of the hub of the radial wing sections of the stator in the propeller jet leads to favorable results with regard to optimization, regardless of whether the propeller is a free-running propeller or is designed as a so-called post-flow propeller.
  • An essentially linear gradient distribution of the wing sections of the stator simplifies design, execution and manufacture. Because the stator and propeller rotate in the same direction, the wing frequency is relatively low, which has a favorable influence on the vibration behavior of the arrangement.
  • the bearing speeds also remain low, so that the bearing and seal can be made simpler.
  • the substantially constant pitch distribution for the wing sections of the stator located outside the propeller jet does not rule out the fact that the pitch distribution of these wing cuts located outside the propeller jet takes account of a possibly present wake field.
  • the gradient of the radial wing sections of the stator in the hub area can be 1.5 to 3 times the constant value.
  • this constant value or the constant pitch of the radial wing cuts outside the propeller jet can be 2 to 3 times the propeller pitch.
  • the design of such an arrangement is based on a so-called optimal propeller, the optimal diameter of which is adapted to the speed of the engine of the ship, the wake conditions and the screw well.
  • the optimal propeller of a ship is to be replaced by an arrangement of propeller and idler, space problems can arise because an additional idler can hardly be accommodated behind an optimal propeller.
  • the advantages of the arrangement according to the invention namely in particular the energy recovery, need not be dispensed with if the diameter of the propeller is smaller than the diameter of an optimal propeller of the same speed. So you can easily reduce the propeller diameter at the same speed without z. B. the number of blades of the propeller would have to be increased. It may be advantageous if the pitch of the reduced diameter propeller is greater than the pitch of the optimal propeller.
  • the arrangement shown in the drawing is one in the screw well 1 at the rear 2 remaining ship not shown housed.
  • a shaft 3 can be seen on which the hub 4 of a propeller 5 is fastened.
  • the propeller 5 is followed by a stator 6, the hub 7 of which is freely rotatably mounted on the hub 4 of the propeller 5. This storage is not shown in detail.
  • the diameter of the stator 6 is larger than the diameter of the propeller 5.
  • the number of blades of the stator 6 is also larger than the number of blades of the propeller 5.
  • the vanes of the stator are designed like a turbine blade on a section 8 within the propeller jet and like a propeller wing on a section 9 outside the propeller jet.
  • the slopes of the wing sections in section 8 within the propeller jet are directed so that they drive the stator 6 in the same direction of rotation as the propeller 5, but at a lower speed.
  • the sections 9 of the vanes of the guide wheel located outside the propeller jet then generate additional propulsion.
  • the diagram shows the pitch distributions of propeller 5 and stator 6.
  • the slope P is plotted over the radius R.
  • the propeller 5 has an approximately constant slope 10, which is represented by a solid line. If necessary, this slope can be adapted to a wake field.
  • the dashed line represents the also approximately constant, but somewhat smaller pitch 11 of an optimal propeller, which also has a somewhat larger diameter than the propeller 5 of the arrangement.
  • the gradient distribution of the radial wing sections of the stator 6 is shown.
  • the sections 9 of the vanes of the guide wheel 6 lying outside the propeller jet have approximately constant gradients 12 in the radial direction.
  • this gradient distribution can also be adapted to a possibly present wake field.
  • the radial wing sections located within the propeller jet or in section 8 have a pitch distribution 13 which, starting from the approximately constant pitch 12 of the wing sections in section 9, increases steadily and linearly in the direction of the hub 7.
  • This basic pitch distribution 12, 13 also applies to arrangements in which the propeller 5 with a constant pitch is replaced by a post-flow propeller, an adjustable propeller or a jet propeller.
  • the propeller 5 has a diameter of approximately 5.2 m, while the optimal propeller would have a diameter of 5.6 m.
  • the average pitch 10 of the propeller 5 is approximately 5.1 m.
  • the guide wheel has a diameter of 6.7 m and its blades have a pitch 12 of approximately 11.8 m in section 9 outside the propeller jet.
  • the slope 13 of the radial wing cut on the hub 7 is approximately 22.3 m.
  • This arrangement has an efficiency of approximately 0.69 compared to an efficiency of 0.65 for an optimized propeller.
