Problems solved by technology

At the same time, the cavitation multiphase flow on the wall will have a large amount of gas leakage like the hovercraft. If the apron system similar to the hovercraft is used, it will increase the difficulty of applying the cavitation multiphase flow technology to moving bodies, especially small moving bodies.

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] The present invention proposes a water surface ventilated double-bubble high-speed navigation moving body structure, the scheme diagram is shown in the appendix Figure 1-3 . The specific names of each number in the figure are as follows: 1—cavitation device; 2—rectification device; 3—cone-column assembly; 4—tail control rudder surface; 5—upper surface of moving body; 6—compressed gas device; 7—ventilator Road; 8—bubble multiphase flow interface.

[0015] Concrete connection form of the present invention sees image 3 , supported by two cone-column assemblies 3 at the bottom of the moving body, usually only these two cone-column assemblies are in contact with water. A rotatable cavitator 1 and a ventilation rectifier 2 are installed on the head of the cone-column assembly (the end of the cone). The main function of the cavit...

Abstract

The invention provides a water-surface aerating double-bubble high-speed voyage moving body structure. Two air compressors are arranged on the surface of a moving body, an aerating pipeline is connected to an output end of each air compressor, two cone-cylinder combinations are arranged at the lower end of the moving body symmetrically, a cavitator and a rectifying device are mounted on the head portion of each cone-cylinder combination, a tail control surface is mounted at the tail of each cone-cylinder combination, and the end of each aerating pipeline extends into the corresponding cone-cylinder combination. Elliptical double-cavitation-bubble multiphase flow is formed at the bottom of the moving body to enable the water-surface moving body to voyage at a high speed, so that the technical problem of applying a cavitation-bubble multiphase flow technology to the water-surface moving body currently can be solved. The water-surface aerating double-bubble high-speed voyage moving body structure is simple in structure, low in cost and easy to implement.

Description

technical field [0001] The invention relates to an underwater navigating body structure, in particular to a water surface ventilated double-bubble high-speed navigating body structure, which belongs to the technical field of water surface high-speed navigating body structures. Background technique [0002] According to the 2006 American Conference on Theoretical and Applied Mechanics report, when frictional resistance drops by 10%, ocean transportation alone can save billions of dollars. Therefore, the water surface moving body can reduce the frictional resistance, greatly improve the carrying efficiency and save the transportation cost. Since the hydrodynamic body is in contact with the atmosphere, it is easy to obtain the air needed for ventilation. Therefore, it is a main development direction to use ventilation to form multiphase flow conditions and realize drag reduction of moving bodies. [0003] At present, air bubbles are formed to reduce the resistance of moving b...
