Definitions
- the present invention relates to a method for operating a ship, in particular a cargo ship, with at least one Magnus rotor.
- Magnus rotors are also referred to as Flettner rotors or sail rotors.
- the Magnus effect describes an occurrence of a lateral force, i. H. perpendicular to the axis and to Anström direction, in a cylinder which rotates about its axis and which is perpendicular to the axis flows.
- the flow around the rotating cylinder can be understood as a superposition of a homogeneous flow and a vortex around the body. Due to the uneven distribution of the total flow results in an asymmetrical pressure distribution at the cylinder circumference.
- a ship is thus provided with rotating or rotating rotors, which in the wind flow one to the effective, d. H. with the maximum speed corrected wind direction, generate vertical force, which can be used for propulsion of the ship similar to sailing.
- the vertical cylinders rotate about their axis and air flowing in from the side then flows around the cylinder preferably in the direction of rotation due to the surface friction. On the front, therefore, the flow velocity is greater and the static pressure less, so that the ship receives a force in the forward direction.
- the invention has for its object to provide a method for operating a ship, in particular a cargo ship, with at least one Magnus rotor, which uses the Magnus effect for purposes other than for the exclusive generation of a propulsive force of the ship. According to the invention, this object is achieved by a method for operating a ship, in particular a cargo ship, with at least one Magnus rotor according to claims 1, 2 and 3 and by a ship according to claim 4.
- the invention provides a method for operating a ship, in particular a cargo ship, with at least one Magnus rotor, which has a step for detecting the wind direction of a wind. Further, the operation of the at least one Magnus rotor is provided with a direction of rotation, so that by the action between wind and Magnus rotor, a force is generated, which is directed substantially opposite to the forward direction of the ship.
- the invention also relates to a method for operating a ship, in particular a cargo ship, with at least two Magnus rotors, wherein at least one Magnus rotor is provided on the port side of the ship and at least one Magnus rotor on the starboard side of the ship.
- the method comprises a step of detecting the wind direction of a wind.
- the method further includes a step of operating the at least one Magnus rotor on the port side of the vessel in a rotational direction such that force is generated by the action between the wind and the at least one Magnus rotor on the port side of the vessel which is directed substantially in the forward or reverse direction of the ship.
- the at least one Magnus rotor on the starboard side of the ship is operated in the direction of rotation opposite to the direction of rotation of the at least one Magnus rotor on the port side of the ship, so that by the action between wind and the at least one Magnus rotor on the starboard side of the ship, a force is generated, which is directed substantially opposite to the direction of the force of the at least one Magnus rotor on the port side of the ship.
- This method is advantageous in that a torque is generated around the center of gravity of the ship by the forces generated on the port side of the ship and the starboard side of the ship.
- the ship can be rotated in a desired direction, which can be specified by the respective directions of rotation of the port and starboard Magnus rotors. If the ship does not experience any other forward or backward directed force, the ship's rotation essentially takes place on the spot. If e.g. by a screw generates a forward or backward force, so the ship can be deflected by means of this torque in one or the other direction, without using a rudder or to assist in the deflection.
- the degree of deflection by the Magnus effect can be determined by the respective rotational speeds of the Magnus rotors.
- the invention also relates to a method for operating a ship, in particular a cargo ship, with at least two Magnus rotors, wherein at least one Magnus rotor is provided on the port side of the ship and at least one Magnus rotor on the starboard side of the ship.
- the method comprises a step of detecting the wind direction of a wind.
- the method further includes a step of operating the at least one Magnus rotor on the port side of the ship. fes and the at least one Magnus rotor on the starboard side of the ship with the same direction of rotation, so that by the action between wind and the at least two Magnus rotors a force is generated, which is substantially in the direction of forward or backward movement of the ship.
- the speed of rotation of the at least one Magnus rotor on the port side of the ship is different from the rotational speed of the at least one Magnus rotor on the starboard side of the ship.
- This method is advantageous, since in a forward or backward movement, which is caused at least in part by the Magnus rotors, a deflection of the ship can take place only or in support of the Magnus rotors. Thus, the deflection can be done together with a rudder to assist them, or even solely by the operation of the invention Magnus rotors to completely relieve the rudder.
- the invention also relates to a ship, in particular a cargo ship, with at least one Magnus rotor, an electric motor associated with the Magnus rotor and an associated converter.
- the ship further comprises a control unit for controlling the inverter, the motor and thus the Magnus rotor.
- the control unit In a first operating mode, the control unit is designed to operate the at least one Magnus rotor in one direction of rotation, so that a force is generated by the effect between wind and magus rotor, which is directed substantially opposite to a forward direction of the ship , In a second mode of operation, the control unit is configured to operate a first Magnus rotor on the port side of the ship in a first direction of rotation such that force is generated by the action between the wind and the first Magnus rotor substantially in the direction the forward direction or the rearward direction of the ship is directed.
- the control unit is further configured to operate a second Magnus rotor on the starboard side of the ship in a second direction of rotation opposite to the first direction of rotation so that a force is generated by the action between the wind and the at least one second Magnus rotor which is directed substantially opposite to the direction of the force of the at least one first Magnus rotor.
- the control unit is configured to operate a first Magnus rotor on the port side and a second Magnus rotor on the starboard side with the same direction of rotation, so that by the action between wind and the first and second Magnus rotor Force is generated, which is essentially is directed in the direction of forward or backward movement of the ship.
- the rotational speed of the at least first Magnus rotor is different from the rotational speed of the second Magnus rotor.
