Abstract
The present invention is a kind of wind power generation blade family design method, belongs to wind power generation blade design field, prototype vane airfoil profile is opened up to distribution from root to blade tip, is progressively successively decreased according to a thickness H and chord length L relative thickness ratio 100% to 16%.The blade design method of the present invention, by in prototype blade spanwise direction certain position block, retain root of blade to truncated region profile, using the same new blade tip of family standard Airfoil Design in prototype blade, by the blade profile of root of blade in new blade tip and prototype blade to the profile integration Cheng Xin of truncated region, the wind power generation blade of different length is formed.This method carries out family design according to certain rule in blade spanwise direction, different length can quickly be designed, adapt to the seriation wind electricity blade of different wind field grades, have the advantages that design efficiency is high, mould utilization factor is high, be a kind of novel design method of wind power generation blade.
Description
Technical field
This technology is related to large-scale horizontal axis wind-driven generator group wind power generating blade design method, belongs to wind-power electricity generation skill
Art field.
Background technology
Wind generating technology is to utilize the wind energy in nature, drives the wind wheel being made up of wind power generation blade to rotate, wind
Wheel is connected by bearing with generator, is driven generator, is allowed to generate electricity.At present, wind-powered electricity generation turns into the fastest developing speed in the world
One of regenerative resource, global installed capacity of wind-driven power average growth rate per annum is 26.3% since 2000.Wind power generation blade is wind
The capital equipment that power generates electricity, the blade of different length can be selected according to the features such as wind field resource.For wind field resource comparatively
Abundant region, short blade can be used, to meet wind power generating set safety requirements；It is and comparatively barren for wind field resource
Region, linear leaf can be used, to improve wind-power electricity generation energy.Therefore, it is necessary to which the features such as being directed to wind field resource designs different length
Spend blade.Conventional method, according to wind power generation blade design principle, brand-new design is carried out to blade profile.Meanwhile to produce this
A little blades are, it is necessary to manufacture corresponding brand-new mould.The problem of so causing be：1st, the design cycle is grown, it is impossible to quick to meet
The market demand；2nd, because blade profile is inconsistent, it is not generally applicable or part is general to produce the mould of these blades, causes mould
Utilization ratio is low, adds wind electricity blade cost.
The content of the invention
For weak point existing for current design method, the present invention proposes a kind of family blade design method, both can be with
Quick design meets the blade of different wind field resources, at the same for manufacture blade mould can also part it is general, greatly improve
Wind electricity blade design efficiency and mould utilization ratio, reduce blade manufacturing cost.
Scheme is used by the present invention solves technical problem：A kind of wind power generation blade family design method, specific step
Suddenly it is： 1）Designed according to wind area grade, using blade momentum theory and related amendment principle, determine the formal parameter of blade, it is complete
Designed into prototype blade profile； 2）Same family standard aerofoil profile in prototype blade is used according to blade profile parameter, designed new
Blade tip；3）Position with the parameter such as new blade tip in prototype blade spanwise direction is blocked；4）New blade tip blocks with prototype blade
The profile integration Cheng Xin in region blade profile, obtain complete new blade profile.
Further, vane airfoil profile is opened up to distribution from root to blade tip, according to a thickness H and chord length L thickness ratio
Value 100% to 16% is progressively successively decreased.Used during specific design：Blade spanwise direction be respectively adopted relative thickness 40%, 35%, 30%,
25%th, the NACA636 series aerospace aerofoil profiles of 21% wind power generation blade special airfoil and relative thickness 18%, 16%.From blade root to
The spanwise direction of blade tip, not using the wind power generation blade special airfoil of relative thickness 40%, 35%, 30%, 25%, 21% and relative thick
Other exhibitions of the NACA636 series aerospace aerofoil profiles of degree 18%, 16% carry out transition to position according to two adjacent profile thicknesses.
According to the actual annual mean wind speed of wind field and Limit of Wind Speed feature, opened up in prototype blade to any two adjacent aerofoils section
Certain position is blocked, and retains prototype blade root to blocking the blade profile of the band of position, while designs new blade tip profile,
New blade profile is combined into newly-designed blade tip and from blade root to the prototype blade profile for blocking position, obtains different length
Same family wind electricity blade, suitable for different wind field demands.
The effect of the present invention is, according to wind field feature, newly-designed blade tip profile with from blade root to blocking position leaf
Piece profile integration Cheng Xin blade.This method can quickly meet the needs of market is to new blade.Meanwhile this method design
Blade, existing molds can be farthest transformed into the mould of production new blade, can be fully sharp by this measure
With original mould, the manufacturing cost of new blade is reduced.
Brief Description Of Drawings
Fig. 1 is the standard airfoil cross-section figure of the present invention 40%；
Fig. 2 is the standard airfoil cross-section figure of the present invention 18%；
Fig. 3,4 are that design cycle of the present invention implements illustration；
Fig. 5 is that different relative thickness aerofoil profiles open up upward distribution stereogram in blade；
Embodiment：
Family blade design method is further illustrated with reference to the accompanying drawings and examples.
Accompanying drawing 3 is applied for the another of family design method.According to actual wind field feature, if local annual mean wind speed and
Limit of Wind Speed is relatively low, causes to be unable to meet demand using the wind power generating set power generation performance of prototype blade, can use family
Design method designs a blade longer than prototype blade.Concrete measure is：In prototype blade relative thickness 25% and 21% aerofoil profile
Between block, be defined as a-quadrant from blade root to position is blocked, block position to blade tip to be defined as B area.According to actual wind
Field feature and the sectional dimension parameter for blocking position, a new blade tip is designed, such as D regions in Fig. 3.By the a-quadrant of prototype blade
New blade is combined into the newly-designed new blade tip in D regions.The new blade is longer than prototype blade, can be applicable annual mean wind speed
The relatively low wind field with Limit of Wind Speed.
Accompanying drawing 4 is applied for a kind of of family design method.According to actual wind field feature, if prototype blade can not bear to work as
Ground annual mean wind speed and Limit of Wind Speed ultimate load and fatigue load to caused by it, family design method design one can be used
The individual blade shorter than prototype blade.Concrete measure is：In prototype blade spanwise direction between the aerofoil profile of relative thickness 21% and 18%
Block, blade root is defined as a-quadrant to position is blocked, and it is to be defined as B area to block position to blade tip.According to actual wind field feature
With the sectional dimension parameter for blocking position, a new blade tip is designed, such as C regions in Fig. 4.By the a-quadrant of prototype blade and newly
The new blade tip in C regions of design is combined into new blade.The new blade is shorter than prototype blade, can be applicable annual mean wind speed and pole
Limit the bigger wind field of wind speed.
