Flap wing underwater and water surface propeller, navigator and propelling method

Abstract

The invention relates to a flap wing underwater and water surface propeller, a navigator and a propelling method. The flap wing underwater and water surface propeller comprises a round base and four flap wings, wherein the four flap wings are arranged on the base and have the same size, each flap wing is sequentially and movably connected onto the base through horizontally installed attack angle shafts and vertically installed swinging and flapping shafts, in addition, each flap wing can singly and respectively rotate around the located attack angle shafts and swinging and flapping shafts for forming a two-freedom rotating mechanism, and the four swinging and flapping shafts are set into the X-shaped layout in an axial symmetry way by using the center line of the base as the symmetry axis. Compared with the conventional propeller propelling mode, the flap wing propelling mode provided by the invention has the advantages that the fluid performance is more complete, and the propelling efficiency is improved. Because the special turning maneuvering action, the turning radius much smaller than that of the propeller propelling can be realized, and the maneuverability performance of the underwater navigator is obviously improved. The flap wing propelling mode applied to the underwater navigator has smaller modification on the structure of the underwater navigator, in addition, the propelling efficiency and the maneuverability are better, and better application prospects are realized.

Description

technical field [0001] The invention relates to the design of an underwater vehicle and flapping-wing propulsion, in particular to a technical method for using flapping-wing propulsion to improve the propulsion efficiency and maneuverability of the vehicle. Background technique [0002] During the long evolutionary process, fishes have developed their own unique diving and swimming abilities through the natural selection of the survival of the fittest. Some have extremely high propulsion efficiency, and cruise at long distances with extremely low energy consumption; some have extremely high explosive acceleration and fast maneuvering response capabilities. The high-efficiency propulsion and high mobility characteristics of fish are the development direction and pursuit goal of future underwater vehicles. According to the development of the bionic robot fish and the results of theoretical analysis, it is considered that the bionic propulsion method has the characteristics of...

Problems solved by technology

However, none of the above-mentioned propulsion schemes can be directly applied to actual underwater vehicles. The main reason is that these propulsion methods require large deformation movements, which have high requirements on control systems, structures, and materials, and engineering applications are very difficult.
