Description
Technical field
The present invention relates to marine propeller technical field, it is related to low noise and high critical speed of a ship or plane feature, can be used for
The integrated motor pump-jet propulsor of the shaftless Push Technology of underwater hiding-machine electric power is realized, more particularly to mixes interlayer composite material removable
Unload formula guide-tube structure and its watertight connection structure.
Background technology
Pump-jet propulsor (Pumpjet, the spray of abbreviation pump) is a kind of rotary assembled hydrodynamic force propeller, by Axisymmetrical Ring
Rotation and static leaf grating composition in shape conduit and conduit.Rotating cascade and static leaf grating are referred to as impeller and stator.Lead
Pipe 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 sky
Change and produce, improve pump spray cavitation performance and radiated noise performance.Stator can be located at before impeller or after impeller, be referred to as preposition
Stator pump sprays and the spray of rearmounted stator pump.The spray of stator before rotor formula pump is currently used primarily in nuclear submarine propulsion, rearmounted stator pump
Spray is currently used primarily in torpedo propulsion.
The operation principle and the hydraulic propeller of above water craft propulsion of pump spray are similar, are also by by propeller current
Momentum difference determines to produce 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
Reason is：1. the number of blade is more, and the load of unit blade area is small；2. there is conduit certain shielding and sound absorption to make to radiated noise
With；3. fluctuation pressure Amplitude Ration propeller is small, and the low frequency spectrum lines noise of generation is lower.The high main cause of the critical speed of a ship or plane is：Adopt
With stator before rotor and zero thrust or low thrust conduit, impeller influent stream condition can be effectively improved, reduces blade tip load, so as to postpone
The tip cavitation of impeller blade is come into being opportunity.Low noise, the advantage of the high critical speed of a ship or plane determine that the spray of stator before rotor formula pump is latent device reason
The propeller thought.
Stator before rotor formula pump sprays the main cause for failing to obtain widespread adoption on conventional submarine：Counterweight is difficult, radiation
The control of noise hardly possible, design difficulty are big.In order to solve counterweight and noise problem, " alertness " level nuclear submarine Beng Pen manufacturer Rolls-
([1] Banks S, Fowler J O.Submersible propulsion unit are (under water in pump spray patent disclosed in Royce
Propulsion plant), United States Patent, No.US8147284B2,2012-4-3) the stator guide-tube structure that pump sprays is adopted
With carbon fibre composite, and impeller still uses metal structure, such as nickel-aluminium-copper either steel.It is possible thereby to infer,
The application of composite is one of key technology that pump spray is used successfully to nuclear submarine propulsion.In " pump spray-hull " acoustic excitation system
In system, in addition to pump sprays the radiated noise with hull itself, pump spray pulsation thrust and torque pass through Propulsion Systems and encourage hull spoke
It is also an important noise source to penetrate noise, and can not also find the measure for effectively suppressing the noise source in a short time.
Propagated to cut off propeller sound source from source by shafting, USN and national defence pre research Plan Bureau (DARPA) in
Combine within 2004 and initiated Tango Bravo projects.The project plan obtain five break-through skills first be realize it is shaftless
Promote, to expect to suppress from source low frequency spectrum lines noise component(s) [2] DARPATANGO that propeller excitation is produced
BRAVO.16February 2011, USA.).In order to realize shaftless propulsion, " Ohio " level for planning to be on active service in 2027 is improved
Type nuclear ballistic missile submarines will using integrated motor pump-jet propulsor ([3] Unite States Naval Institute,
Ohio replacementprogram, USA, 2012.12.Wikipedia)。
The integrated electric-motor pump spray of shaftless drive-type 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
A kind of synchronized propeller that there is air gap between rotating Vortex, motor stator and rotor.IMP is also known as wheel rim propeller,
Either ring drives formula propeller, is generally made up of conduit, motor and blade, without static leaf grating part, i.e., in no pump spray
Stator component.Integrated electric-motor pump spray is conventional IMP further development and improvement.Core technology advantage is：By electromotor no axis
Push Technology and pump spray promote the outstanding advantages of low noise, the high critical speed of a ship or plane fully-integrated, can play the pump spray sound of itself
Shafting sound source excitation system can be eliminated again by learning performance advantage.Meanwhile, propulsion electric machine is transplanted to behind propeller inside out of ship,
Effective utilization space in cabin can be substantially improved, this is also " outside ship of one of five key technologies in TANGO BRAVO projects
One of main purpose of arm discharge system " research and development.Therefore, integrated electric-motor pump spray will most possibly turn into shaftless electric propulsion
Preferred propeller.And the installation and later maintenance of integrated motor are realized, guide-tube structure design must is fulfilled for design for disassembly will
Ask.Therefore, the design to conduit attachment structure brings a series of new problems, and this is also naval vessels at present not yet extensively using shaftless
The one of the main reasons that pump spray is promoted.
