Definitions
- the invention relates to a rudder arrangement in an underwater vehicle.
- Modern underwater vehicles today have a so-called X-rudder, for example the submarine class U 212 A or Dolphin class, or a rudder, for example the submarine class U 214 or Los Angeles class.
- These rudders consist of four rudder blades (whether full-swords or split rudders), with the rudder two rudders horizontally and two rudders vertically arranged.
- the rudder blades In the case of the X-rudder, the rudder blades each have an angle of approximately 45 ° relative to the horizontal.
- these rudder arrangements can have a certain susceptibility to the location by Aktivsonar.
- the susceptibility may be given by vertical surfaces, for example in the case of the rudder, or by two surfaces at an angle of approximately 90 ° to one another, for example the X-rudder. This is due to the fact that a location by a surface vehicle or a submarine with an active sonar is already due to the distance regularly at an angle of less than 10 ° to the horizontal.
- the object of the invention is to provide a rudder arrangement which has a reduced susceptibility to an active sonar without restricting the maneuverability of the underwater vehicle.
- the underwater vehicle according to the invention has a rudder, wherein the rudder has a first, a second, a third and a fourth rudder blade.
- the rudder has a first group with the first and the second rudder blade and a second group with the third and the fourth rudder blade, wherein the first group and the second group are arranged offset in the longitudinal direction of the underwater vehicle.
- the first rudder blade and the third rudder blade port and the second rudder blade and the fourth rudder blade are arranged starboard.
- the first group and the second group are arranged adjacent to one another in the longitudinal direction of the underwater vehicle. Due to the adjacent arrangement, all rudder blades can be arranged as far as possible at the rear. As a result, the hydrodynamic behavior and thus the maneuverability compared to today's rudder arrangement is the least changed.
- the first group and the second group are spaced apart in the longitudinal direction of the underwater vehicle. As a result of the spacing, localization can also be made more difficult by a bistatic sonar, that is to say by a sonar, in which transmitter and receiver are arranged at different locations, for example on different vessels.
- the rudder blades have a sound-reflecting surface.
- the sound characteristic impedance Z F is relevant, the sound characteristic impedance Z F being the product of density p and speed of sound c.
- the thickness of the material and the wavelength in the material are also relevant.
- Plastic foams, in particular hard foams, have proven to be good reflectors for the frequencies commonly used in sonar. Therefore, the rudder blades are particularly preferably on the surfaces in contact with the water made of plastic foam, in particular hard foam.
- the rudder blades have an inclination relative to the horizontal of 20 ° to 70 °.
- the rudder blades have an inclination relative to the horizontal of 50 ° to 60 °.
- an angle of about 45 ° below the horizontal By avoiding an angle of about 45 ° below the horizontal, a reflection back to the transmitter is avoided, the sonar wave is reflected by the rudder blade upwards, is reflected back from the water surface to the rudder blade and back from the rudder blade Towards the transmitter is reflected back.
- Too steep an arrangement of the rudder blades of more than 70 ° should also preferably be avoided in order to avoid direct reflection to the transmitter. It should be noted here that the reflection never takes place exclusively exactly at a certain angle, but that in the case of sound there is always an angular distribution in the reflection.
- the first group is arranged on the rear side and the first and the second rudder blade have an inclination relative to the horizontal of 50 ° to 60 °, wherein the inclination is below the horizontal.
- the second group is arranged on the bow side, preferably directly adjacent to the first group, and the third and the fourth rudder blade have an inclination relative to the horizontal of 50 ° to 60 °, the incline being above the horizontal.
- the first group is arranged on the bow side and the first and the second rudder blade have an inclination relative to the horizontal of 50 ° to 60 °, wherein the inclination is below the horizontal.
- the second group is arranged at the rear, preferably immediately adjacent to the first group, and the third and fourth rudder blades have a horizontal inclination of 50 ° to 60 °, the incline being above the horizontal.
- the first group is arranged on the rear side.
- the second group is arranged on the bow side, preferably directly adjacent to the first group.
- the second and the fourth rudder blade have a horizontal inclination of 50 ° to 60 °, the incline being above the horizontal.
- the first and third rudder blades have a horizontal inclination of 50 ° to 60 °, the inclination being below the horizontal.
- the first group is arranged on the rear side.
- the second group is arranged on the bow side, preferably directly adjacent to the first group.
- the second and fourth rudder blades have an inclination to the horizontal of 50 ° to 60 °, the inclination being below the horizontal.
- the first and third rudder blades have an inclination to the horizontal of 50 ° to 60 °, the incline being above the horizontal.
- the underwater vehicle has a round cross-section and the rudder blades are mounted close to the equator. Below the equator, the horizontal cross-section through the shell of the underwater vehicle is considered, in which the underwater vehicle has the largest extent.
- equatorial means that the rudder blades are arranged no more than 10% of the circumference of the underwater vehicle away from the equator. Particularly preferably, the rudder blades are arranged at the equator.
- the underwater vehicle has a flattened cross-section, the cross-section at the sides of the underwater vehicle each having an edge.
- the rudder blades are arranged at the edge. By this arrangement it is avoided that form right angles between the shell of the underwater vehicle and the rudder blades.
- the embodiment of a flattened cross-section with an edge on each side is particularly preferred, as this can reduce the target dimension for the underwater vehicle as a whole.
- the underwater vehicle is preferably a submarine, an autonomous underwater vehicle or a torpedo. Particularly preferred is a submarine.
- the AIM-9 Sidewinder has a cruciform rudder assembly and stabilizer assembly which could also be modified according to the invention. This also applies to all other embodiments of the invention. The only modification is that the rudder blades can be designed to be particularly reflective for radar.
- Fig. 1 the prior art classical X-rower assembly is seen, with the submarine 10 having a flattened cross-section to minimize the target size.
- the rudder blades 20 are each at an angle of about 45 ° to the horizontal just before Propeller 30 arranged at the stern of the submarine 10.
- the disadvantage is that an incoming sound wave 40 of an active sonar is directly reflected back as a reflected sound wave 50 to the transmitter.
- the submarine 10 can be located, even if it already has a flattened cross-section as shown here.
- Fig. 2 shows a rudder assembly according to the invention on a submarine 10.
- the first group 22 is formed of two rudder blades, which are arranged at the rear just before the propeller 30 directed at an angle of about 50 ° to the horizontal down.
- the second group 24 is offset longitudinally of the underwater vehicle and disposed adjacent to the first group 22, the rudder blades being angled at an angle of about 50 ° to the horizontal.
- An incoming sound wave 40 is reflected off the transmitter as a reflected sound wave 50. By avoiding a 45 ° angle it does not come together with the water surface not shown here to a return reflection to the transmitter.
