Problems solved by technology

In the bionic vortex ring control technology, the current common practice is to manufacture a bionic vortex ring control device to generate and adjust the structural state of the vortex ring, and optimize the propulsion performance of the vortex ring. Specifically: imitate protozoa and use cilia to generate and adjust the vortex ring Structure, that is to rely on the swing of a large number of cilia on the body surface to complete the manufacture and adjustment of the vortex ring, and realize the propulsion movement, but because the cilia are too small, it is very difficult to drive, and this type of bionic vortex ring control device is not very applicable; imitating fish Such organisms use wavy swings to generate and adjust the vortex ring structure, that is, rely on the fluctuation or swing of the body and fins to complete the manufacture and adjustment of the vortex ring. , imitating manta ray robot fish, etc., but such control devices are often limited in their application on underwater vehicles due to their large size, complex structure, and difficulty in adjusting the flow field structure; imitating coelenterates such as squid The recoil generates and adjusts the vortex ring structure, that is, the jet vortex ring structure is formed by changing the volume of the water storage cavity to complete the propulsion movement. This kind of bionic vortex ring control device can be more conveniently manufactured and adjusted. Flow field structure, optimized propulsion force and propulsion effect, etc., have the advantages of large propulsion force, high propulsion efficiency, strong maneuverability, and small environmental disturbance, and are more suitable for application in underwater resource exploration and underwater reconnaissance.
