, long march 3 carrier rocket transfer 8 Yao emissive field of spaceflight of Chinese article prosperous, will use at implementing visit month project bridge of 4 period magpie relays the star launchs the mission 2 numbers. Current, the rocket begins each general assembly to check the work in succession in emissive field. Before this, mixed in January this year at the beginning of Feburary, goddess in the moon bridge of 6 tasks detector, magpie 2 satellites already in advance arrives at emissive field, each test before also undertaking emissive intends the work.
Press a plan, this year first half of the year, our country will launch magpie bridge early or late 2 He Change 6. Goddess in the moon 6, want to launch a detector to collect lunar area to moon the reverse side namely, bring back the earth to consider next. What effect does that magpie bridge have 2 numbers? Because cannot correspond directly between moon the reverse side and earth, should launch magpie bridge first so 2 this relay satellites, it can go to will come the signal contact between 6 detector and earth station puts up the goddess in the moon of sampling of moon the reverse side ” of “ magpie bridge.
Magpie bridge “ is aureate big umbrella”Soft star carries aerial gauze
In magpie bridge 2 before, actually 5 years many before, already bridge of a magpie relays the satellite is goddess in the moon 4 moon the reverse side lands, exploration task provided communication relay service. The feature with magpie striking bridge has a such “ namely aureate big umbrella ” , be called a star to carry large can spread out aerial. Pass this “ aureate big umbrella ” , realized the earth and the communication with rear moon. There is antenna of shape of umbrella of satellite of magpie bridge relay in the lab of Shanghai Dong Hua university shrink than appearance, this aureate be braided with the metal and big umbrella is become unexpectedly.
In the lab of institute of spin of Dong Hua university, the reporter saw ” of this “ big umbrella, one is spread on frame of umbrella thin thin maize gauze. Expert introduction, gauze is the star holds the crucial part that can launch aerial to reflex electromagnetic wave, can spread out in emissive orbit process, its can spread out the key that reflexes a face to braid a technology in warp knitting.
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: The rocket blasts off when going up, it is to shrink inside the rocket. Arrived after orbit, it opens an orgnaization to develop satellitic reflex range into a meshy antenna slowly through exhibiting, so we are called can spread out aerial. It is flexible, so it can spread out, so we want those who pass spin to braid a technology to form so a cloth cover.
The star carries what can spread out raw material of day on-line gauze to choose is metallic molybdenum silk, to increase its performance, the expert made more film processing and treatment again on extremely fine molybdenum silk.
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: The raw material that we use calls aureate molybdenum silk, it is plating of the surface on the foundation in molybdenum silk gold, the reflectivity because of gold is first-rate.
Reporter: Tinsel is particularly fine if spreading out, is braiding to ability of a few especially other technology is braided so equably?
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: This is our a few crucial technologies. Above all molybdenum silk is very fine, probably 15 to 30 micron, 1/4 what still be less than hair silk diameter. Pull so make itself have very great difficulty, additionally the surface still has aureate. Aureate the prison that should keep certain later is spent, we are a few more impure organic element, raised the tenacity of metallic raw material on one hand, also let it express a mask to have finer affinity additionally. So, the improvement of a few craft makes of molybdenum silk aureate be not Chang Jian to originally in braiding a process to become later.
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: Weaving a course is relatively special and delicate and complex, above all we should undertake and line. Because it is too fine, we invented a kind and line twisting technology, tinsel is together 3 times, the structure is very stable.
Innovation braids a technology to make satellitic antenna gauze bigger lighter
The expert tells a reporter, metallic molybdenum silk is very soft, odd because a molybdenum silk is too fine and puissant and insufficient, it is to use 34 molybdenum silk to close together to braid gauze normally so. Nevertheless now, in the satellite large below the tide that turn, aerial reflexes a face to do bigger more, this is helpful for the communication between heaven and earth. But the area is large, weight also is met heavier. How can you allow antenna big light? Study group innovation braids a technology, can use sheet now molybdenum silk is braided bigger lighter gauze, the biggest about the same field having goal is so big.
Begin from 2017, industry of Dong Hua university uses spin flexible group of structural material innovation begins to tackle key problem technology of warp knitting of monofilament of metallic molybdenum silk. Through effort of 5 years, innovation research and development technology of warp knitting of ” of “ small pulling force and equipment, great the weight that reduced new-style antenna to reflex a face.
Institute of spin of Dong Hua university teachs Jiang Jinhua: It is compared with original photograph, likelihood weight light 1/3 or 1/4, cost may fall lowlier, weight also falls very lowly. So, a square metre may overcome the smallest now network to be less than 20 grams again.
Land explores antenna of 4 01 stars to approach basketball field size
The land that blasted off in August 2023 explores 4 01 stars, its reflex a face to use monofilament of silk of molybdenum of extremely fine metal to undertake braiding namely, developed area of its annular big antenna nears the area of place of field of a basketball, great raised fast track satellite to be able to spread out aerial to reflex area area and communication ability.
Institute of spin of Dong Hua university teachs Jiang Jinhua: Because prospective antenna may do bigger more, the likelihood reachs 100 meters of level or kilometer class, ask the reseau structure of monofilament can be contented exceed large satellitic antenna application. Communication is more and more frequent now, requirement data flux is bigger and bigger. If line of action is too little, cannot satisfy frequent tall flux data to transmit. Now we not only doing molybdenum silk, we also are making the raw material of other, also making a few attempt application.
“ wing of Tian Zhou”Braid the ” of “ tennis racket that go out
On January 17, 7 freight airship is Tian Zhou dimensional station sent a batch of lives goods and materials and experimental equipment. The sun ala substrate of airship of freight of former nature boat also is to braid actually come out, its fibre glass is meshy structure, look to resemble a tennis racket.
Fibre glass is meshy the structure is light quantify and fight oxidation
According to introducing, what airship of day boat freight uses is ala of half rigid sun, the frame of ala of this kind of sun is carbon fiber, the wire side that fibre glass net comprises is among, similar a tennis racket, solar cell piece go up at fibre glass net with respect to hook. This kind of fibre glass is meshy structure, had light quantified characteristic, and to environment of low course space medium atomic oxygen, plasma has stronger defend quality.
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: The space has many atomic oxygen to exist, oxidation capability is very strong, so material of general and organic high polymer is oxidized very badly, want to choose a kind to fight the stuff with oxidation very expensive ability so, we chose inorganic material fibre glass.
Fibre glass is had fight oxidation, weight to wait for an advantage gently. But want to braid a net with fibre glass, difficulty is very great.
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: Fibre glass also is put in a very big weak point, its braid function to be not constant error, because it is very fragile. Spin material follows fibrous fineness be closely related, fiber is thinner, plasticity is very strong. Pass and after twisting, it becomes a very thick raw material, can achieve a such goals through braiding.
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: It still has a profit, light, it is mesh, the solar battery piece hook above.
The colophony on fibre glass besmear more be able to bear or endure dimensional environment
Fibre glass is being made up weave solar energy after the substrate of sail board, return the resin on meeting besmear, in order to promote its property.
Institute of spin of Dong Hua university teachs Jiang Jinhua: Besmear colophony basically is to let the surface more level off, also can rise to protect action to to it. Because resemble organic silicon this kind of colophony, it is able to bear or endure dimensional environment is better, and stability still has wearability to also can rise, can improve integral performance greatly.
The “ spin that your place does not know”Still can do these
New material is applied, make up weaver art newly, let spin this word is more than the concept of dress of bureau be confined to. Carry aerial gauze ” like the “ star that a moment ago mentioned, had fought navigation in satellite of magpie bridge relay, north get applied on a variety of satellites such as satellite, mobile satellite. Spin, be in not only the application of spaceflight domain is wider and wider, make in big airlines also be well worth doing in biology application domain even.
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: Spin is a kind of material, the likelihood is the material of a kind of characteristic, e.g. spaceflight. Spaceflight domain, e.g. extensible antenna, it wants large change. Rolled steel is rigid material, do not have method to do so big, locomotive also do not have a law locomotive. Need a kind of soft thing fold so, the setting that arrived to use next spreads out, have textile only can make it this kind of soft thing.
Communication is trouble-free the mobile phone connects a satellite
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: Large can spreading out aerial basically is to enhance the communication of high-powered satellite and ground data, basically apply in satellite of a few telecommunication satellite, navigation, fight in north useful also. Connect a satellite one day inside communication, also be the antenna that used reflection face. Satellite and our mobile phone is OK communication, this antenna was to have very conclusive effect.
Biology applies kind of viscera blood-vessel to fill piece
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: Spin still has a lot of application domains to be able to be extended, for instance: Biology is medical domain. The viscera of human body, hemal, fill piece, these things are to follow product of spin technology, spin closely related.
Carbon fiber fabric makes large aircraft
Industry of Ministry of Education of professor of Dong Hua college uses Chen Naliang of director of textile engineering research center: C919 has used the carbon fiber tissue of our country now, the dosage of C929 will be bigger. Spaceflight territory is very much also, this kind of rigid data that uses make it of carbon fiber material is already special and general. And flexible the application of spin material just just begins now, so we say spin science and technology also is to have very big perspective.
