In, inventor provides a kind of combined type cavitation device comprising and conical sections and frustum-conical portion, leading portion are conical sections,
Back segment is that the structure of frustum-conical portion designs.Patent publication No. is that the patent of invention of 105352704 A of CN discloses that " one kind can
Become the circular cone cavitation device of cone angle ", in the patent of invention, inventor provides the head that cavitation device is mounted on sail body, including one
The construction design method of fixed disc and multiple sliding discs.But they only provide the design method of cavitation device, there is no just
The stabilization of vacuole optimizes.
Summary of the invention
In response to the deficiencies in the existing technology, the present invention provides a kind of supercavity submarine navigation devices, are navigated by water by improving
The structure of body designs, and effectively realizes the supercavity that steady steaming body leading portion is formed, reduces running resistance, the noise reduction of sail body, mention
The high underwater sailing body speed of a ship or plane.
The present invention achieves the above technical objects by the following technical means.
A kind of supercavity submarine navigation device, including sail body and ring-shaped skirt；The sail body includes leading portion tapered segment
And column part；Leading portion tapered segment surface is equipped with several annular grooves, the tail portion appearance of the sail body column part

The tail portion of row body column part is externally provided with air vent, for being connected to the air bag and the sail body internal cavities；When the gas
When capsule unaerated, the ring-shaped skirt does not protrude sail body column part outer surface.
Further, the annular groove is equally spaced on leading portion tapered segment, and the annular groove quantity is 3-4.
Further, the ring-shaped skirt outer diameter is identical as sail body column part outer diameter.
Further, the air bag is the elastic material of fold, and when the air bag unaerated, several air bags are weighed mutually
It is folded.
Further, the air bag is no less than 3.
Further, the air vent is uniformly distributed along sail body column part axis,
Further, the quantity of the air vent is no less than 8 in any air bag.
The beneficial effects of the present invention are:
1. supercavity submarine navigation device of the present invention is equipped with annular groove, annular by leading portion tapered segment surface
The effect of groove be store gas under normal pressure, into it is underwater when, stored by air facilitate sky caused by cavitation device
Bubble is further grown up, so that covering entire sail body.
2. supercavity submarine navigation device of the present invention, ring-shaped skirt is equipped with by tail portion, in ring-shaped skirt inner cavity
Be provided with air vent, air vent is through sail body surface connection navigation intracoelomic cavity, when supercavity occurs after entering under water, gas supply
Gas in inner cavity is filled in the air bag of ring-shaped skirt by hole because pressure acts on, so that air bag expands, effectively prevent supercavity tail
Portion is involved in plume, improves the stability of supercavity.
