Dual-body underwater vehicle propelled by mixing bionic swing and propellers

Abstract

The invention discloses a dual-body underwater vehicle propelled by mixing bionic swing and propellers, and relates to a dual-body structural underwater vehicle propelled by combining bionic swing andthe propellers. The dual-body underwater vehicle propelled by mixing bionic swing and the propellers is used for solving the problems that limitations exist in advantages of an existing bionic underwater vehicle and a propeller type underwater vehicle and an existing underwater vehicle propelled by combining bionic and gliding has low speed of floating upward and sinking downward and low flexibility of turning. According to the technical scheme, the dual-body underwater vehicle propelled by combining bionic swing and the propellers is characterized in that bionic swing type and the propellertype propelling are combined, bionic swing type propelling in the horizontal direction is realized through swing of a tail fin, and minor radius turning is realized; rapid floating upward and sinkingdownward are realized in the vertical direction through two front and rear propellers in the middle; and rotational inertia is increased through a dual-body structure of the vehicle, so that rotational resistance is larger when the vehicle is subjected to water flow disturbance, and capacity of resisting disturbance is improved. A detecting device carried by the dual-body underwater vehicle propelled by combining bionic swing and the propellers can be used in fields such as underwater environment detection and underwater target detection.

Description

technical field [0001] The invention relates to the field of underwater vehicles. In particular, it relates to a double-body structure underwater vehicle propelled by a combination of bionics and propellers. Background technique [0002] At present, the propulsion methods of underwater vehicles can be divided into two types. There are three kinds of propulsion methods for underwater robots: propeller propulsion has the characteristics of large propulsion power, fast speed of aircraft but loud noise; The balance attitude is easy to adjust, the noise is low, the turning radius is small but the operating radius is small, and the efficiency is not high; the gliding propulsion method has the characteristics of low energy consumption, long range, but the turning radius is large and not flexible enough. [0003] There are various methods of propulsion for unmanned underwater vehicles. One is the propeller-propelled underwater vehicle represented by UUV for a long time; the other ...

AI Technical Summary

Problems solved by technology

Although its swing-type bionic propulsion method and its gliding-type navigation method have low water resistance and low noise, they cannot float up and dive quickly, and their navigation maneuverability is poor; secondly, due to the large water resistance area of ​​its gliding wing, its turning radius Large, resulting in poor navigation flexibility of the aircraft; at the same time, the method of adjusting the floating and submerging of the aircraft through the screw and heavy buoyancy is slow and difficult to control, and its wingspan is too large to navigate in complex and narrow waters. reduced navigation space
