Description
Technical field
The invention belongs to marine propeller technical field, more particularly to high, the low feature of radiated noise with the critical speed of a ship or plane,
It can be used for the pump-jet propulsor that the latent device of underwater navigation promotes.
Background technique
As (referred to as pump spray, pump spray rotor are driven mechanical pump-jet propulsor by propulsion electric machine in cabin, and there are cardan shafts
System) it advocates war the successful application on submarine in naval power, the world, such as " extra large wolf " grade, " Virginia " grade and " alertness " grade are attack
Submarine and the Borei class nuclear ballistic missile submarines etc., spraying using external pump is main thruster, and " Virginia " grade
(referred to as shaftless pump spray, propulsion electric machine remove the external shaftless drive-type pump-jet propulsor of Submarine Equipments out of cabin, spray complete set with pump
At together, when work, is soaked in seawater, cancels Propulsion Systems) supplemented by push away, and next-generation " Ohio " grade modified war
Slightly nuclear-powered missile submarine is formed using external shaftless pump spray as the research plan of main thruster, and pump spray Push Technology has become newly
One of the top layer core technology of type submarine vibration and noise reducing.
Compared with 7 leaf highly skewed propellers (referred to as 7 leaf paddles), the theory and technology advantage for pumping spray is: cavitation later, noise more
It is low, high efficient district range is wider.It is more than 7 leaf paddle structure components in itself to remove pump spray, the Hydraulic Design difficulty is bigger outer, U.S. AD report
Accuse a kind of (new pump spray design theory [R] of [1] Furuya O, Chiang W L.A New Pumpjet Design Theory
.Tetra Tech.Inc.Report NO.TC-3037,1986.) also illustrate: the significant difference of pump spray and 7 leaf paddles is that pump sprays
Significantly more efficient hull boundary layer incoming flow can be utilized, so that the sluggish speed of incoming flow for entering pump spray blade grid passage is significantly lower than ship
The body speed of a ship or plane, while discharging jet speed is pumped extremely close to the speed of a ship or plane, so that hull-pump spray propulsion system energy loss is very
It is few.The technical advantage is mainly derived from conduit and streams and is divided into inside and outside flow field in the presence of will pump to spray, and hull and conduit boundary layer flow are total to
Same-action is increased monotonically again so that pump spirt stream first increases to be reduced rapidly afterwards in radial direction, and velocity gradient is big and there are inflection point ([2]
The Low Noise Design mechanism and design of Yang Qiongfang, Wang Yongsheng pump-jet propulsor apply the Wuhan [M]: the Central China University of Science and Technology publishes
Society, 2016.), be radially increased monotonically with 7 leaf paddle influent streams difference.It could be said that pump spirt stream VELOCITY DISTRIBUTION is more compared with 7 leaf paddles
Add complexity, more sensitive to the distribution of ship tail wake velocity, the water cycle performance curve between hull empennage configuration is stronger.Cause
This, pump spray more needs to pay attention to the design of hull empennage configuration when designing.
From the point of view of the pump of existing weaponry and equipment sprays and promotes engineer application, " extra large wolf " grade and the pump spray of " Virginia " grade promote submarine equal
Using " wood " font hull empennage configuration, Le Triomphant-class pump spray promotes submarine to use I-shaped hull empennage, while pumping spray and pushing away
X-shaped empennage is mostly used into torpedo, is different from current 7 leaf paddle and promotes the common cruciform tail configuration of submarine.In addition, from dock
In the construction photo of " Virginia " grade submarine SSN-789 can be seen that hull tail cone section small end and the diameter ratio of big end is greater than
0.35, hence it is evident that different from the tail cone section small end and outside diameter ratio generally less than 0.15 where the cross wing in front of 7 leaf paddles, taper is more
It is small, it is corresponding that 7 leaf paddles are typically larger than with the hub diameter ratio of pump spray.Above-mentioned practical application shows: cross hull empennage configuration is no longer
It is to adapt to pump the good of spirt stream to match, to give full play to pump spray low noise, anti-cavitation and the moderate potential technology advantage of efficiency, it is necessary to
Optimal improvements hull empennage configuration is started with the new empennage configuration of quantitative design from Flow details feature.
In hull empennage configuration design aspect, with " the submarine rudder wing " or " hull empennage configuration " or " X in Chinese patent net
When shape rudder " or " the attached body of submarine " are that keyword is retrieved, fail to retrieve related application.Even being answered in middle National IP Network's science
It is the theme when retrieving in database with " the submarine rudder wing " or " hull empennage ", research report also focuses primarily upon the typical cross of band
The difference of hydrodynamic force coefficient and the influence to propeller wake distribution, do not send out in the hull manipulation process of the wing and the wooden word wing configuration
The existing hull empennage-relevant discussion of pump spray propulsion system.Main cause is: country's pump spray promotes engineer application still in a step
Section, current tackling problems in key technologies focus primarily upon on the blade design of pump spray itself, can not yet take into account entire pump pushing system.
From the point of view of the application value of pump push technology, although being limited to the sensibility in Military Application field to a certain extent,
During the civilian marine resources development such as current underwater unmanned navigation latent device, manned deep-sea vehicle, frogman's vehicle, also need
Using above-mentioned technology, the value of market economy brought by the technological innovation is in the same old way very important, therefore, it is necessary in ship for civil use
It is synchronous in propulsion field to research and develop and widely popularize this technology.
Summary of the invention:
