Abstract
The invention provides a water-air mixed jet propeller and belongs to naval vessel propelling power modes. The water-air mixed jet propeller comprises propellers, a cold pressing turbofan, a water inlet, a front water channel, a jet orifice, an air inflow opening, an air way, a surrounding air way and air inlets. The water-air mixed jet propeller is characterized in that the propellers are arranged in a cylinder which is provided with the front water way and a rear water way and is provided with two open ends and the closed periphery, the annularly and densely distributed air inlets are formed in the cylinder wall of the rear water way, and water flow driven by the propellers and air flow driven by the cold pressing turbofan are mixed in the rear water way and then poured out from the jet orifice. Compared with the prior art, foam water with volume compression elasticity is formed by a water body with volume rigidity due to mixing of air. A historical leap from pure open propeller rigid fluid propelling to closed compression elasticity fluid jet propelling of a naval vessel is achieved.
Description
First, technical field：
The present invention relates to naval vessel thrust power pattern, and in particular to a kind of gas-vapor mix jet propeller.
2nd, background technology：
Propeller is the basic motive pattern of fluid three dimensions implements motion.Due to air fluid height physically
The elasticity of compression and combustion-supporting property chemically, make the aircraft of operation gas fluid space, have been quickly completed from the propulsion of open type spiral oar
To the leap of semiclosed whirlpool oar jet engine propulsion.Due to rigidity characteristics of the water sheet in volume, make to run in aqueous fluid
Naval vessel just follow for a long time, still open type spiral oar propulsion history sexual norm, there is no the change of matter.
3rd, the content of the invention
The purpose of the present invention is limited to and present situation for more than, the ship propeller propulsion mode to running on aqueous fluid,
A kind of gas-vapor mix jet propeller of the leap meaning with matter is provided.
The purpose of the present invention is achieved through the following technical solutions：
A kind of gas-vapor mix jet propeller, including propeller, turbofan of colding pressing, water inlet, front water channel, rear channel, injection
Mouth, air inlet, air flue, circular air flue and air inlet, is characterized in that propeller is arranged at water inlet, front water channel, rear channel and spray
Loophole, in the cylinder of both ends open all round closure, turbofan of colding pressing is arranged at the air inlet of air flue, the high speed driven by propeller
Current flow through the air inlet gathered in air flue in the rear channel with the high pressure gas of turbofan driving of colding pressing and enter post blend, by spraying
Loophole releases.
Described circular air flue, is characterized in that being shunted above rear channel, and two-way circular wrappings rear channel forms insertion
Around air flue.
Described circular air flue, is characterized in that at the upper side of rear channel, unidirectional loop wrapping rear channel, form cecum
Around air flue.
Described propeller and turbofan of colding pressing, is characterized in that being respectively provided with and open, stop and speed governing gear, using propeller independence
Propulsion or turbofan of colding pressing match joint propulsion.
The gas-vapor mix jet propeller of the present invention, it then follows fluid mechanics principle, makes full use of aqueous fluid in volume
High elastic property of the gentle fluid of rigidity characteristics in volume, completes the blending of aqueous vapor under artificial driving flow regime,
The foam water with the elasticity of compression is made, directly definitely thrust is comprehensive with what the elastic relative force of continuity was combined to form rigidity
Power is closed, in realizing aqueous fluid environment, from simple, simple open propeller the leap of whirlpool oar jet propulsion is advanced to.
4th, illustrate：
Fig. 1 is the side generalized section of gas-vapor mix jet propeller.
Fig. 2 enters local sectional schematic diagram for the circular air flue tangent of gas-vapor mix jet propeller.
Fig. 3 cuts local section schematic diagram for the circular airway side of gas-vapor mix jet propeller.
In figure：1 propeller, 2 cold pressing turbofan, 3 water inlets, water channel before 4,5 rear channels, 6 jets, 7 air inlets, 8 air flues,
9 annular air channels, 10 air inlets.
5th, specific embodiment：
With reference to Figure of description, the present invention is described in more detail：
As shown in figure 1, have water inlet 3 and front water channel 4 before propeller 1 is arranged at, after have rear channel 5 and jet 6
Both ends open, in the cylinder of all round closure.Turbofan 2 of colding pressing is arranged with the air inlet 7 of air flue 8, and air flue 8 is after backward curving is arrived at
The upper side of water channel 5, is paperwrapped in the wall profile of rear channel 5 and circularizes air flue 9, annular air channel with the flat space manner of progressively constriction
Densely covered air inlet 10 is uniformly arranged on 9 walls of rear channel 5 for covering.
When using, when the naval vessel of installation gas-vapor mix jet propeller needs low cruise, propeller 1 is activated individually and advances,
Because the high-velocity flow in rear channel 5 forms lower pressure environment, the gas in annular air channel 9 is made, is passively sucked by air inlet 10,
The foam water Jing jet 6 for forming low-gas content is gushed out, and its reaction propulsion naval vessel is with cruising speed advance.Naval vessel needs height
During speed operation, while starting turbofan of colding pressing, a large amount of pressure-airs inject rear channel 5, make rear water with active form, Jing air inlets 10
Water body is gushed out, with more due to the quick-fried increasing of incorporation volume of air with the more powerful resilient foam water Jing jet 6 of tool in road 5
Big and persistence counteracting force promotes naval vessel to advance at utmost speed.
Fig. 2 and Fig. 3 provides the two ways that air enters rear channel 5, and Fig. 2 show the annular air channel 9 of insertion, there is provided
In a balanced way air-flow is entered from 360 degree of peripheries equilibrium of rear channel 5, and Fig. 3 show the annular air channel 9 with guidance quality in the same direction and enters
Pore 10, the foam water for making input air forms eddy flow, extends its counteracting force distance, selects for different tonnages and function naval vessel
Using.
In addition to the technical characteristic described in description, the known technology of those skilled in the art is.
