Embodiment Construction

[0052] figure 1 Shown is a top view of an underwater vehicle 10 having a bow section 20, a midship section 30 and a stern section 40, wherein the underwater vehicle has a rudder 60 (here a cross rudder) in the stern section 40. form) and propeller 70. The underwater vehicle 10 has an outer shell 50 comprising a curvature of the midship portion in the longitudinal direction of the underwater vehicle 10 , as can be seen in comparison to the pressure vessel 80 shown in simplified form as a cylinder. In practice, the pressure vessel 80 also has rounded ends, preferably hemispherical ends, at the bow and stern, which have been omitted here for simplicity. The pressure vessel 80 also does not have to occupy the full length. In particular, the weapon barrel can be arranged in the bow.

[0053] figure 2 A first exemplary cross-section is shown. The shell 80 has a hexagonal cross-section, the widest point 100 being exactly flush with the center 90 formed by the center of the cyli...

Abstract

The invention relates to an underwater craft (10) that is less likely to be detected and comprises an outer shell (50), a bow section (20), a stern section (40) and a midship section (30); the outer shell (50) of the midship section (30) has a polygonal cross-section when viewed transversely to the longitudinal direction of the underwater craft (10), and the outer shell (50) of the midship section(30) is curved along the longitudinal direction of the underwater craft (10).

Description

technical field [0001] The present invention relates to underwater vehicles, in particular submarines, having an outer shape optimized to reduce the possibility of detection by means of active sonar. As a result, the distance from which the underwater vehicle can be detected can be significantly reduced. Background technique [0002] Currently, underwater vehicles, in particular military submarines, traditionally have a cylindrical basic shape (in simplified form) in the midship region with a hemispherical bow section and a conical stern section. This shape is streamlined and easy to manufacture as a monohull or catamaran. [0003] Today, sonar is used in particular to detect submarines, wherein the aim is preferably to detect over long distances (eg 100 km). This causes the sonar's sound waves to strike the underwater vehicle at an extremely shallow angle, parallel to the water's surface. To avoid detection, reflections of the sound waves must be avoided particularly tow...
