Abstract

The submarine consists of a pressure hull. This pressure hull is at least partially surrounded by the shell. In addition, the submarine comprises at least one auxiliary drive as well as a main propeller drive. The secondary drive is an in-line thruster which can be moved from the non-operational position in the intermediate space between the pressure hull and the shell to a movable position outside of the shell without a through shaft or through connector through the pressure hull.

Description

Submarine {SUBMARINE}

The present invention relates to a submarine having the features described in the preamble of claim 1.

In addition to submarines, larger ship's rudder installations, including military submarines, develop key effects above the relatively large minimum speed. In addition, the change in the direction of the ship by these key arrangements is affected with a relatively large radius of curvature.

The submarine has a so-called traversal bow thruster as a secondary propulsion in addition to the main propeller propulsion to allow maneuvering at very low speeds. The traversal thrusters allow for the precise maneuvering of these vessels, such as docking maneuvers. However, these may affect the sailing characteristics of the vessel in an undesirable way during normal sailing. Although suspiciously adversely affected by this effect is mainly the flow conditions along the hull, it is so small that the additional thrust to be exerted on it can be neglected, and the disturbance caused by the flow is a modest generation of noise. Entails. This is not a disadvantage to the aquatic, but it is a very serious problem for military submarines which are almost entirely located by acoustic characteristics.

It is an object of the present invention to provide a submarine with secondary propulsion which improves maneuverability while having acoustic characteristics comparable to a submarine without secondary propulsion against this background.

This object is achieved by a submarine having the features set forth in claim 1. Further advantageous forms of this submarine are deduced from the dependent claims, the drawings as well as the description that follows.

Submarines according to the invention, however, are typically not necessarily manned submarines and at least partly comprise a pressure hull surrounded by a shell. In normal operation, the submarine typically has a main propeller drive disposed at the stern. In addition, the stern of the submarine is equipped with a key facility to control the submarine in normal navigation.

In maneuvering at or at the lowest sailing speed, the submarine generally includes at least one auxiliary drive. The basic idea here is to use a so-called inline-thruster which can be moved from the non-operational position in the intermediate space between the pressure hull and the submarine envelope as a secondary drive to a movable position outside of the submarine envelope. to be.

In-line thrusters can be understood as propeller propulsion, in which a stator is integrated into an annular housing and driven electrically. An annular hollow rotor is rotatably mounted in a housing in which the stator is disposed, the rotor being submerged with an inner peripheral propeller blade disposed therein and extending in the middle axial direction of the rotor. Form a water-permeable tunnel. Thus, a drive scheme driven directly by a drive motor without the use of gear means is presented, which is advantageous in that it has a very low acoustical property of the auxiliary drive leading to relatively high efficiency.

In-line thrusters are usefully applied when the submarine according to the invention is preferably started in confined spaces when the main propeller drive is not in operation or when the main propeller drive is at very low speed. In this case, the in-line thruster is moved from the non-operational position to the movable position outside of the shell through the opening formed in the shell. Otherwise, the in-line thruster can advantageously always be mounted in a non-moving position in the intermediate space between the pressure hull and the shell, ie in the contour of the submarine, causing little acoustical characteristics.

Advantageously, the instruments and in-line thrusters presented for functional operation do not have shaft lead-through or linkage lead-through through the pressure hull or otherwise weaken the structure of the pressure hull. And very extensive sealing is required.

Preferably, the in-line thruster is disposed at the bottom or keel of the submarine. The arrangement of the in-line thrusters is essentially infinite with respect to the longitudinal direction of the submarine, but is preferably arranged in close proximity to the submarine's bow or bow. At the height of the longitudinal axis, ie with respect to the largest width of the submarine, the placement of the in-line thruster is equally possible to bring about a submarine depth change by propulsion in the vertical direction.

The axial direction of the thrust inline and thus accompanying the propulsion direction may advantageously be set in terms parallel to the longitudinal axis of the submarine in an angular range of at least 180 degrees for maneuvering. To this end, the in-line thruster is usefully located in the movable position outside the envelope and is rotatably arranged in this angle range in a stepless manner with respect to an axis perpendicular to the longitudinal axis of the submarine and, in the most preferred case, the longitudinal direction of the submarine. The forward propulsion of the submarine at any angle to its axis can be generated by the in-line thruster.

An electric motor or hydraulic rotation drive, in which the in-line thruster is coupled in operation, is provided as a drive for rotating the in-line thruster. The use of hydraulically rotating drives for in-line thrusters is advantageous as it is arranged in the intermediate space where water enters between the pressure hull and the shell under the design of a suitable pressure resistance, and any gear means is placed in the pressure hull with a pressure hull. There is no need to penetrate the wall, but only to provide pressure hull penetration for hydraulic inlet and electrical supply.

The rotatable arrangement of the inline thrusters can be advantageously taken from the frame on which the inline thrusters are mounted. The frame is rotatably mounted in an intermediate space between the pressure hull and the shell to move the in-line thruster from the non-operational position between the pressure hull and the shell of the submarine to a movable position outside the shell. Typically with this design a rotary drive in which the in-line thruster can be rotated to the movable position is also arranged on the frame.

Preferably, the frame is rotatably stored between the pressure hull and the submarine shell in such a way that the axis on which the frame is rotatably mounted is perpendicular to the longitudinal axis of the submarine and perpendicular to the axis of rotation of the in-line thruster. Thus, the rotational axis of the frame is parallel on the cross section of the pressure hull and parallel to the longitudinal axis of the submarine. The frame is preferably rotatable at an angle of about 90 degrees, and the axis of rotation through which the in-line thruster can be rotated in its movable position around it is essentially on the longitudinal axis of the submarine in the non-moving position between the pressure hull and the shell. Side by side parallel and essentially perpendicular to the longitudinal axis in the movable position.

The frame can advantageously be pivoted in a hydraulic or electrical manner. Hydraulically actuated piston-cylinder arrangement or electrical linear drive may be provided coupled to the frame. Thus, in a submarine the piston-cylinder arrangement is pivotally linked between the pressure hull and the shell, and the frame can be rotated from the non-moving position to the movable position, and vice versa by stretching the piston of this arrangement. However, hydraulic or electrical rotational drive is preferably used to pivot the frame to be placed in the intermediate space between the pressure hull and the submarine envelope. This rotational drive may be coupled directly to the rotational axis of the frame, and may preferably be connected such that the rotational axis is disposed away from the rotational axis of the frame. In this case, the frame can be coupled in movement to the rotating cylinder, particularly advantageously via a toggle lever mechanism.

In a more advantageous form according to the invention it may be envisaged to place a fairing part in the outer housing of the in-line thruster which forms part of the outer shell of the submarine. The openings formed in the sheath allow the in-line thruster to be rotated to a movable position outside the sheath, which can be closed by this fairing. The fairing portion is usefully designed in the form of a plate and can be made of, for example, a lightweight glass fiber composite or a carbon fiber composite. The placement of the fairing portion on the housing of the in-line thruster is advantageous in that the fairing portion closes the opening formed on the shell when the in-line thruster is in the non-moving position, where the outside of the fairing portion is aligned with the outside of the shell. In addition, the fairing portion is usefully arranged on the nozzle of the housing, ie the in-line thruster, such that its flat side is aligned essentially parallel to the intermediate axis of the in-line thruster. In this way, the fairing part generates negligible flow resistance with the application of in-line thrusters.

According to the present invention there is provided a submarine having auxiliary propulsion to improve maneuverability while having acoustic characteristics comparable to a submarine without auxiliary propulsion.

The submarine according to the invention comprises a pressure hull 2, with the outer shell 4 arranged at the bottom of the submarine apart from the pressure hull 2 (Figs. 1 and 2). The frame 8 of the subsidiary drive of the submarine is thus arranged in an intermediate space 6 which arises between the pressure hull 2 and the shell 4.

The frame 8 comprises an elongated box-shaped carrier structure 10, in which case the longitudinal extension of the carrier structure 10 in each case is shown in particular in FIGS. 3 to 6. The projections 12 extending essentially transversely in are formed on two longitudinal sides of the carrier structure 10 aligned parallel to each other. The frame 8 is rotatably mounted on a pivot 14 arranged in the intermediate space 6 in the end region away from the carrier structure 10 in the projection 12. Pivot 14, although not shown, is aligned perpendicular to the longitudinal axis of the submarine, and perpendicular to the vertical axis of the submarine perpendicular thereto.

A hydraulic rotation drive 18 is disposed at one end 16 of the carrier structure 10, and a rotatable peg 20 of the rotational drive 18 is coupled to the interior of the carrier structure 10. . The in-line thruster 22 disposed at the other end spaced apart from the one end 16 of the carrier structure 10 is rotatably coupled to the rotational drive 18 via the peg 20.

The in-line thruster 22 includes an annular or tubular housing 24, incorporating a stator that is not recognized in the figures but is designed to be equally annular therein. The rotor 26 is rotatably disposed in the housing 24 and is typically surrounded by the stator. The rotor 24 is designed to be hollow like a tube. The propeller blades 28 are disposed around their inner side and extend essentially radially in the middle direction of the rotor 26.

The hydraulic rotation drive 30 is arranged adjacent to the pivot 14 in the intermediate space 6 between the pressure hull 2 and the shell 4 (FIGS. 3 to 5). The placement of the rotary drive 30 is such that the rotatable pegs 32 of the rotary drive 30 are aligned parallel to the pivot 14 axis. The rotation drive unit 30 serves to rotate the frame 8 and the in-line thruster 22 disposed therein. To this end, the peg 32 of the rotary drive 30 is coupled to the frame 8 in an operational state via a toggle lever mechanism 34.

The toggle lever mechanism 34 includes a first lever 36 and a second lever 38 connected to each other in a joint manner through the joint 40. The lever 38 is designed in an arcuate shape of L. The lever 36 is connected in such a way that it is rotatably fixed to the peg 32 of the rotary drive 30 at the end spaced from the joint 40. The lever 38 is connected in such a way that its end is spaced apart from the joint 40 and rotatably moves through the joint 42 of the projection 12 of the frame 8.

The functional mode of the auxiliary drive of the submarine according to the present invention is as follows.

First, the frame 8 to which the in-line thruster 22 is coupled is completely disposed in the intermediate space 6 between the pressure hull 2 and the shell 4 in the non-moving position, and the in-line thruster 22 The pairing portion 44 essentially arranged tangential to the outside of the housing 24 closes the opening 46 formed in the shell 4 (FIG. 3).

The frame 8 is rotated with the in-line thruster 22 in a stepless manner by the operation of the rotary drive 30 until the in-line thruster 22 is located in the outer movable position of the shell (Fig. 4 to 6). Thereby, the rotational movement of the peg 32 of the rotation drive part 30 is switched to the pivoting movement of the frame 8 with respect to the shaft 14 via the toggle lever mechanism 34.

In the movable position (FIG. 6), the in-line thruster 22 is aligned to the position required for starting (FIGS. 6-10). This is accomplished by proper operation of the hydraulic rotational drive 18 which is connected in a movably manner to the in-line thruster 22 in an appropriate manner. When the in-line thruster 22 is to be rotated from the movable position back to the non-moving position in the intermediate space 6 between the pressure hull 2 and the shell 4, first, the fairing portion 44 first starts the frame ( It is necessary to rotate the inline thruster 22 so that it is disposed perpendicular to the pivot plane of 8) and behind the inline thruster 22 with respect to the pivot path. Subsequently, the rotation of the frame 8 takes place opposite to that described above.
