Description
Technical field
The present invention relates to marine propeller technical field, it is related to can be used for low noise and high critical speed of a ship or plane feature
The integrated motor pump-jet propulsor for realizing the shaftless Push Technology of underwater hiding-machine electric power, in particular to it is removable to mix interlayer composite material
Unload formula guide-tube structure.
Background technique
Pump-jet propulsor (Pumpjet, referred to as pump spray) is a kind of rotary assembled hydrodynamic force propeller, by axial symmetry annular
Rotation and static leaf grating composition in conduit and conduit.Rotating cascade and static leaf grating are referred to as impeller and stator.Conduit
Section is usually airfoil type, is typically designed as deceleration type conduit, can flow through the water flow speed reduction of impeller blade to postpone cavitation
It generates, improves pump spray cavitation performance and radiated noise performance.Stator can be located at before impeller or after impeller, and it is preposition fixed to be referred to as
The spray of minor pump and the pump spray of postposition stator.The pump spray of stator before rotor formula is currently used primarily in nuclear submarine propulsion, the pump spray of postposition stator
It is currently used primarily in torpedo propulsion.
The working principle for pumping spray and the hydraulic propeller of above water craft propulsion are similar, and by passing through propeller water flow
Momentum difference determines to generate the size of net thrust.The outstanding advantages of pump spray are that radiated noise is low, the critical speed of a ship or plane is high.Low main of noise
The reason is that: 1. the number of blade is more, and the load of unit blade area is small；2. conduit there is certain shielding and sound absorption to make radiated noise
With；3. fluctuation pressure Amplitude Ration propeller is small, the low frequency spectrum lines noise of generation is lower.The main reason for critical speed of a ship or plane is high is: adopting
With stator before rotor and zero thrust or low thrust conduit, it can be effectively improved impeller influent stream condition, reduce blade tip load, to postpone
The tip cavitation of impeller blade is come into being opportunity.The advantages of low noise, the high critical speed of a ship or plane, determines that the pump spray of stator before rotor formula is latent device reason
The propeller thought.
The pump spray of stator before rotor formula fails: counterweight is difficult, radiates
Noise is difficult to control, design difficulty is big.In order to solve counterweight and noise problem, " alertness " grade nuclear submarine Beng Pen manufacturer Rolls-
([1] Banks S, Fowler J O.Submersible propulsion unit are (underwater in the disclosed pump spray patent of Royce
Propulsion device), United States Patent, No.US8147284B2,2012-4-3) the stator guide-tube structure of pump spray is adopted
With carbon fibre composite, and impeller still uses metal structure, such as nickel-aluminum-copper either steel.It is possible thereby to infer, it is multiple
The application of condensation material is one of the key technology that pump spray is used successfully to nuclear submarine propulsion.In " pump spray-hull " acoustic excitation system
In, other than the radiated noise of pump spray and hull itself, pump sprays pulsation thrust and torque and motivates hull to radiate by Propulsion Systems
Noise is also an important noise source, and can not also find the measure for effectively inhibiting the noise source in a short time.For
Cut off from source propeller sound source by shafting propagation, USN and national defence pre research Plan Bureau (DARPA) in
Combine within 2004 and has initiated Tango Bravo project.Quasi- five break-through skills first obtained of the project is that realization is shaftless
It promotes, it is expected low frequency spectrum lines noise component(s) [2] DARPATANGO for inhibiting propeller excitation to generate from source
BRAVO.16February 2011, USA.).In order to realize shaftless propulsion, plans " Ohio " grade being on active service in 2027 and improve
Type nuclear ballistic missile submarines will be using integrated motor pump-jet propulsor ([3] Unite States Naval Institute, Ohio
replacementprogram,USA,2012.12.Wikipedia)。
Shaftless drive-type integrate electric-motor pump spray be integrated motor propulsor (Integrated Motor Propulsor,
IMP one kind), be by motor stator be embedded in pump spray conduit in, rotor and pump spray impeller blade blade tip integrate
It is synchronized that there are a kind of propellers of air gap between rotating Vortex, motor stator and rotor.IMP is also known as wheel rim propeller,
Either ring drives formula propeller, is usually made of conduit, motor and blade, without static leaf grating component, i.e., without in pump spray
Stator component.Integrated electric-motor pump spray is the further development and improvement of conventional IMP.Core technology advantage is: by electromotor no axis
Push Technology is sprayed with pump promotes low noise, the outstanding advantages of the high critical speed of a ship or plane fully-integrated, can play the sound of pump spray itself
It learns performance advantage, shafting sound source excitation system can be eliminated again.Meanwhile after propulsion electric machine is transplanted to propeller inside out of ship,
Effective use space in cabin can be substantially improved, this is also " outside ship of one of five key technologies in TANGO BRAVO project
One of the main purpose of arm discharge system " research and development.Therefore, shaftless electric propulsion will most possibly be become by integrating electric-motor pump spray
Preferred propeller.And to realize the installation and later maintenance of integrated motor, guide-tube structure design must satisfy design for disassembly and want
It asks.Therefore, a series of new problems are brought to the design of conduit connection structure, this be also naval vessels be not yet widely applied at present it is shaftless
One of the main reason for pump spray promotes.
