Underwater vehicle

Abstract

The invention discloses an underwater vehicle comprising a body, a first tail fin component, a second tail fin component and a pectoral fin component, wherein, the first tail fin component and the second tail fin component can be connected onto the body asway side by side along the transverse direction of the body; the pectoral fin component is connected onto the body. The underwater vehicle of the invention has high-efficiency propulsion capability and high maneuverability, and can be widely applied to the fields of military affairs, scientific research, resource exploration and the like.

Description

technical field [0001] The invention relates to the field of underwater vehicles, in particular to an underwater vehicle based on the principle of bionics. Background technique [0002] In recent years, Unmanned Underwater Vehicle (UUV, Unmanned Underwater Vehicle), as a new type of combat power, is being highly valued by various military powers. At the same time, modern high-tech warfare conditions have also put forward higher and higher requirements for the navigation capability, maneuverability and stealth of unmanned underwater vehicles. However, traditional UUVs generally use propeller-based propellers. These conventional propulsion methods obviously have disadvantages such as low propulsion efficiency, difficult positioning, lack of flexibility in turning, and imprecise hovering. [0003] In view of this, in the new generation of underwater combat platforms, bionic unmanned underwater vehicles based on the principles of bionics have emerged. Compared with the aforeme...

Problems solved by technology

Generally speaking, bionic fish with multi-joint caudal fins can generate propulsion through body fluctuations. Although this type of structure is close to low-energy consumption such as trout-style movements, its fluctuations account for a high proportion of body length, so its propulsion Ability (ratio of speed to body length) is generally inferior to that of the single-joint caudal fin

On the other hand, multi-joint tail fins are also less reliable and cost-effective than single-joint tail fins

However, it is difficult to further improve its propulsion ability by using a single tail fin, and a particularly prominent problem is that the body of the bionic fish underwater vehicle that relies on a single tail fin will shake with the swing of the tail fin, which not only leads to poor motion stability, Moreover, the propulsion efficiency is also reduced
