Announce as the country such as the United States in order to rise but the policy that capacity of second birth energy attachs most importance to a dot and target, a few involve new-style improve but technology of second birth energy obtained certain favorable circumstances. Company of Xenecore of American Newyork city is one devotes oneself to development to have more high-energy quantity to capture the company of the lamina of more efficient and wind- driven turbine of ability, this company is using the professional knowledge of domain of spare parts of its composite material, design and develop the sector wind-force lamina that is based on obstruction.
Xenecore company held water 2010, at first company presiding apparitor holds father Jerry Choe concurrently to use tennis racket of composite material of carbon fiber of material technology research and development through be in sporting goods application, formed multinomial and patent technology. Have when drive to realize carbon fiber tennis racket high-powered with high power, and the effect that should reduce bat adversary arm as far as possible, the development that passes 18 months period, he and his group developed a kind of material and craft solution, undertake appearing on the market selling with Xenecore trade name now, this is a kind thermoplastic tiny ball product, can use the structural core that makes composite material part.
After obtaining afore-mentioned abecedarians to succeed, this company is in thermoplastic of tiny ball technology optimize further on invested a large number of capital, won 250 multinomial patent in the whole world. This company discovers the new opportunity that the scope of application of Xenecore product can expand from the tennis racket, if do not have the lamina of is based on obstruction wind- driven turbine of man-machine lamina and the closest design.
Xenecore is developing a kind of sector, wind- driven turbine that is based on obstruction, although realize high energy likely also in small wind to capture
The characteristic of lamina of traditional wind report reachs blemish
About two years ago, the engineering technology that Choe and Xenecore group begin to consider how to use this firm and product develop lamina of wind- driven turbine. Now nowadays, most wind- driven turbine has long and thin flying airfoil blade, these lamina basically use lift to generate electricity. When wind passes blade, the inferior pressure that blade a side forms is perpendicular pull at wind direction use blade, make its rotate rotor, generate electricity energy move in turbine.
These lamina are made by fibre glass envelope normally, and prop up by cap of bridge of ala of carbon fiber composite material in longer lamina. Wind report lamina is placed normally in opening type mould, vacuum infuse, use next fight cut core of celiac board, bubble and adhesive to be assembled together.
However, the earliest windmill looks very different, its characteristic is wide, the ligneous lamina of smooth, sector generates electricity through obstruction, wind-force is used at pushing blade the way of aweather directly. When wind- driven turbine just was invented, everybody is using instruction, can capture because of it more wind. But as a result of use data, the first batch of these lamina are a problem, because the earliest windmill is,use not quite soft, durable data (like cloth) build.
1919, er uncle of German physicist A is special · Bates published him famous now capture about wind and the Bates that blade designs is mensurable. According to this one law, blade use lift can capture only at most 59% of wind kinetic energy. This one theory affected the figure of plane wing and lamina of wind- driven turbine, make lift the biggest change, resistance is the least change, use thin and bent design, this kind of design up to now still very popular.
According to the view of Choe, afore-mentioned energy of 59% capture leading is theoretic maximum only, because actual wind- driven turbine captures,the efficiency of energy wants low much, but this alleged maximum is not is the maximum that is aimed at current data. Mix because of the fibre glass that uses nowadays carbon fiber composite material is solidder, lighter, the metallic stuff property that is used at producing blade and wing than shellfish Ci times is close friends more. Accordingly, had gotten optimizing promotion considering existing material function, at the outset best design shows likely nowadays efficiency is very low, satisfy a requirement no longer.
Notable is, have a lot of wind- driven blade that are based on obstruction using all the time since the design is long-term, for example Savonius type is perpendicular and wind- driven turbine, its characteristic is lamina of two cups shape rotates around central turbine. These turbine compare the turbine efficiency that is based on lift normally low much, because be in perpendicular setting, two lamina held back a few wind that blade other in part can capture actually. However, their simple design and capture in small wind area the ability of energy makes they are in the turbine in family or commercial environment very popular.
The horizontal wind-force turbine that Choe and his group begins to develop a kind to update, this turbine is OK utmost favourable geographical position uses instruction, the most important is it used advanced composite material.
The modernization of structure of wind report lamina is designed
Xenecore group is inchoate a challenge that face is, because be based on the turbine of lift to already made a standard, because the simulation software this nowadays is used at the analysis only,be based on the function of the fan of lift. Choe and his group tried a lot of analysis tools, the act that uses software of hydrokinetics of Ansys Fluent computation finally to go up in blade to wind undertakes building a model.
Use these models, its target is it is OK to develop a kind utmost ground captures the lamina of obstruction, can generate electricity inside turbine, at the same time with as far as possible little weight bears Gaofeng load. Xenecore group tries to make blade of composite material of carbon fiber of a kind of solid above all, but worse than intensity, even if solid state carbon fiber board also can rupture below tall wind-force.
Final, xenecore designed lamina of sector of a kind of monomer, call Fanturbine, by coping and bottom and cuticular composition, the surface is enclothed have Xenecore thermoplastic tiny ball. These are cortical the costal consolidate that uses the I-steel that be called. This design is copy is unripe, because costal region shows sector from center, very the leaf that goes up like palmy leaf.
Xenecore gets the inspiration of the force of palmy leaf and grain, developed from the center the costal region structure of outward fan
Blade uses one pace to compress shape craft is made, use high standard to measure carbon fiber and epoxy resin to increase intensity and stability with utmost ground, and with as far as possible light weight is counteractive Gaofeng load. Design of monomer of type of an organic whole still aims utmost land increases stability, be in theoretic the life that prolongs blade, because do not have juncture or adhesive,can damage as the elapse of time or fatigue. Current, the first version of these lamina is relatively lesser, dimension is 3×3 foot, the target is to enlarge larger size, with competing with traditional wind- driven lamina.
Good for production each lamina, in putting the carbon fiber fabric with good cut aluminium to make coping and bottom pattern, and will multilayer Xenecore filmy paper places the coping in every cortex. The mould closes, below high temperature and high pressure, the bubble of light simple structure that tiny ball expands to be united in wedlock with cerebral cortex. This craft production gives onefold, without what seam, do not have adhesive, I bridge the monomer spare parts of swing.
The turbine design of Xenecore includes the 4 fan blade on every turbine, enclothed the usable surface of about 80% to accumulate. Wind drives blade, make rotor rotates, produce energy in turbine thereby. Teach Dr. Paulo Abdala according to aviation of deceased Brasilia university a white paper 2021, electricenergy production depends on greatly wind speed. The consistence of compressed sector lamina conduces to in blade two side generation presses difference abruptly, this meeting increases wind speed and electricenergy production.
Xenecore hopes to develop more large-scale lamina, can work together with traditional turbine
According to the imitate of Xenecore, below ideal condition, fan is theoretic can achieve the biggest the wind energy of 98% captures. In addition, the design of this lamina can bear the wind of hurricane class, in imitate, it can be borne to be as high as by the proof horary 376 miles wind speed, the top speed of far outclass hurricane. Choe expresses: These lamina are not changing the circumstance of existing infrastructure to fall to move on existing turbine.
Development latent capacity of future
2022, xenecore begins to produce 3×3 foot the 5 kilowatt of blade are small-sized turbine, the branch that sells its South America sells business, online inside global limits sale. Choe explanation says, the solar battery that these small-sized systems aim to replace the power likeness that is used at the residence and enterprise board, offer equal power, but their function is close friends more, moving cost is 3 times lower.
At present fan sells with the small-sized version of 5 kilowatt, use at installation to be on the residence or commercial housetop
The course checks, these blade electricenergy production are the septuple of the lamina of traditional wind report of similar measure. The oldest system that Xenecore has tested is the turbine of a 100 kilowatt, blade is 11 feet wide. It has a million to cover with tiles level version is in the design.
Choe expresses, be in before long in the future, people is very interested bigger Fanturbine lamina, point out this technology changes his costume or dress likely France is general and electric GE is current the biggest Haliade X turbine, this can increase its size 100 times, from 14 million tile increases 1.4 thousand tile.
Current, this company is seeking investor and partner, promote this technology in order to help be down one phase. To prove this technology, xenecore next the target is to transforming ex-service wind- driven turbine to be built on mast and install the turbine with a 1 made of baked clay million.
