Definitions

  • the invention relates to a submarine with the features specified in the preamble of claim 1.
  • the prior art includes submarines powered by an electric drive motor disposed in the pressure hull of the submarine.
  • the mechanical power generated by the drive motor is transmitted via a shaft from the drive motor to a propeller arranged on the outside of the pressure hull of the submarine.
  • Such a shaft is usually connected via an elastic coupling with the drive motor and guided by a pressure body passage through the pressure hull of the submarine to the propeller.
  • the shaft must be sealed to the pressure body bushing against the pending at maximum depth of the outside pressure, which is associated with a large design effort.
  • the seal required for this has the disadvantage that, in order to ensure the pressure tightness even at maximum depth, presses with considerable force on the shaft, which in turn leads to relatively large energy losses in the power transmission from the drive motor to the propeller.
  • DE 2 001 510 such as DE 1 895 486 are drives for submarines known, which are arranged outside the pressure hull.
  • drives containers are provided in each case, which are arranged at a distance from the pressure body.
  • these drives are not suitable because their arrangement generates large signatures, which may possibly lead to a discovery of the submarine.
  • US 5,607,329 A US 3,101,066 A , which is considered to be the closest prior art, and US Pat. No. 5,941,777 submarines are known which have an external rotor motor as a propeller drive. This is needed to control the submarine US 5,607,329 A known submarine a separate rowing device.
  • two propeller drives are provided, of which a first in the area of the bow and a second are arranged in the region of the stern of the submarine. A control of this submarine takes place in that the two propeller drives are operated in opposite directions, whereby the position of the propeller blades can be changed.
  • the US Pat. No. 5,941,777 known submarine is arranged outside the pressure hull rear region, on which the propeller drive is arranged to pivot for controlling the submarine by means of a separate drive obliquely to the longitudinal axis of the submarine
  • the present invention seeks to provide a submarine, which compared to the previously known submarines with an electric drive improved propulsion and in the invention has improved rowing properties.
  • the submarine according to the invention which is in particular a military submarine, has a pressure body and is equipped with a propeller driven by an electric drive motor. According to the invention, this drive motor is arranged outside of the pressure chamber interior. In this respect, it is not necessary in the submarine according to the invention to provide a pressure body structure which weakens the pressure body structure for the propeller shaft. As a result, the hitherto necessary sealing of the propeller shaft with respect to the pressure body in the region of a pressure body leadthrough becomes superfluous, whereby also the associated power losses in the power transmission from the drive motor to the propeller are eliminated. In addition, the arrangement of the drive motor outside the interior of the pressure hull a significant gain in space in the pressure hull, which is against the background of submarines in itself limited space of particularly advantageous importance.
  • the propeller forms a rudder device in the submarine according to the invention. Accordingly, the propeller is designed to not only feed the submarine generated in the direction of the longitudinal axis, but also allows any movements of the submarine transverse to this longitudinal axis.
  • the drive motor of the submarine according to the invention is designed as an external rotor. That is, the rotatable rotor of the electric drive motor, with which the propeller is typically operatively connected, circumferentially surrounds its stationary stator.
  • the electric drive motor can be designed both as an asynchronous motor and as a synchronous motor.
  • the drive motor is preferably designed as a synchronous motor and particularly advantageous as a synchronous motor in external rotor design in which the annular external rotor or rotor is permanently magnetized and preferably a plurality of distributed over its circumference Permanent magnets for generating the exciter field, while the stator carries a plurality of distributed over its outer circumference arranged Bestrombare coils.
  • the synchronous motor or the coils of the stator are expediently supplied with electrical energy via an inverter from the DC network of the submarine, wherein the inverter can form a structural unit both with the synchronous motor and can also be arranged at a distance from the synchronous motor.
  • the rotor of the drive motor forms part of the propeller.
  • a plurality of preferably radially aligned to the rotor propeller blades for generating a feed can be arranged on the outer peripheral side of the rotatable rotor distributed over the circumference.
  • the drive motor and the propeller form virtually a structural unit, so that advantageously no additional co-Der Stator of the drive motor is incorporated according to the invention in the Druckzzowandung.
  • the pressure body may have on its outer side an annular recess extending over the entire circumference of the pressure body, in which the likewise ring-shaped stator, which preferably has a plurality of juxtaposed coils for generating a magnetic field traveling on the circumference of the stator, is preferably fixed by means of a welded joint.
  • the rotor of the drive motor is typically arranged on the outside of the outer circumference of the stator, wherein the rotor advantageously also engages in the pressure-body wall.
  • the outside of the rotor is aligned with the outside of the pressure body, ie.
  • the rotor and the areas of the pressure-body wall surrounding the rotor together form a substantially smooth outside of the submarine, on which only the propeller blades arranged on the outer circumference of the rotor protrude radially.
  • the recess of the Druck Economicswandung in which the rotatably mounted on the stator rotor is incorporated, is suitably designed so that the rotor can not move in the axial direction even under maximum feed force of the propeller.
  • the propeller advantageously has propeller blades whose angle of attack, ie their orientation, can be changed transversely to their longitudinal extent. To change their angle of attack are the individual
  • Propeller blades advantageously each individually controllable. This allows any movement of the submarine transversely to its longitudinal axis, so both movements in the horizontal and in the vertical direction.
  • rudder devices advantageously also horizontal movements transverse to the longitudinal axis of the submarine possible if the submarine does not move in the direction of its longitudinal axis
  • the rudder forces required for a particular lateral or deep movement can be generated at a corresponding angle of attack only by the propeller blades, which are located during the rotation of the rotor just in a certain peripheral portion of the rotor, while the other propeller blades would counteract this movement at the same angle of attack.
  • the angle of attack of the propeller blades is individually variable as a function of their circumferential position on the rotor. Similar to the rotor blade adjustment of a helicopter, the change in the angle of attack of the individual propeller blades takes place cyclically because of the rotational movement of the rotor.
  • each propeller blade is in each case movement-coupled with its own adjusting device, d. H.
