On July 24 14 when 22 minutes, emissive field of article prosperous spaceflight, 5 B carrier rocket asks long march lift manned spaceflight of current big monomer implement dimensional station asks day experiment cabin to ignition takes off, enter successfully book orbit; Beijing time on July 25 3 when 13 minutes, cabin of core of Yu Tianhe of butt joint of success of cabin of experiment asking a day is forward port. Press job plan, 14 spacefarers take divine boat group will enter cabin of experiment asking a day subsequently. Article introduction launchs a process this to reach cabin asking a day and dimensional station the application of the technology of other system 3D that print and composite material. Ask day experiment cabin to heat accuses subsystem to use 3D to print a technology

Spacecraft is when course, did not have the protection of aerosphere, below the circumstance of sun illuminate, exterior temperature can amount to 100 ℃ above, and the temperature when doing not have sunshine arrives 0 times under 100 ℃ . Regard our country dimension as big spacecraft, cabin of experiment asking a day is in extremely extremely cold in hot aerospace environment, in the easy environment that all sorts of equipment inside spacefarer and cabin are in 20 much Celsius all the time, the heat that station of 5 courtyards space asks group of science and technology of spaceflight of this profit from day experiment cabin to heat accuses a group to develop accuses subsystem.

(come from: Spark learns MarsSociety) make big oven to avoid to ask day experiment cabin, heat accused a group to develop system of home's at present old ” of “ aerospace air conditioning, offerred a comfortable temperature to ask day experiment cabin environment. System of ” of air conditioning of this “ aerospace includes to measure the wind inside the aerospace appearance with custom-built body, airtight separation cold system and the liquid cooling system that spread all over whole cabin. According to group of spaceflight science and technology 5 courtyards ask controller of loop of fluid of day experiment cabin Introduction Wang Dewei, the group developed system of 3 liquid cooling to ask day experiment cabin, the quantity of heat that produces all sorts of equipment or experimental load is collected and radiation arrives outside aerospace, of the experimental load of above of class of supportable number kilowatt medicinal powder hot. Among them one is to be what load of the experiment outside cabin undertakes temperature is ensured technically to come loose hot loop, second developed technology of 4 a powerful person, condition of installation of load of the experiment outside solving cabin was opposite the influence of return system, the technology of much valve adjusting control that on weight station of excel international space uses. In the meantime, development staff developed material of heat conduction of large size, efficient interface, give attention to two or morethings of maintenance of the load outside cabin and heat conduction dual-purpose. The scientific test that ” of “ dream season, “ asks day ” experiment cabin to —— uses at the respect such as physics of biology, material, small gravitational fluid, foundation respectively (come from: Spark learns MarsSociety) in the development in ” of “ aerospace air conditioning, to satisfy a part the temperature of special device controls a demand, 5 courtyards ask group of spaceflight science and technology day experiment cabin to heat accuses to developed a group to still use partial black science and technology, technology of all alone of heat conduction of Xi of the white appearance that the sun reflectivity that the wind that includes what use inside airtight separation to be based on 3D to print uses on equipment of peripheral of cold cooling technology, cabin exceeds 90% , black lead. One of design passwords of ” of “ aerospace fort: Light quantified structure + light quantified material + 3D is printed

The structure that the space stands and orgnaization subsystem are just as ” of “ aerospace fort, let life be able to put add in aerospace. To make the domestic ” of “ aerospace strong, solid, durable, structure of station of 5 courtyards space and solution of group of orgnaization subsystem development locked up group of spaceflight science and technology light quantify, the fivefold “ that sealing, macrobian life, high reliability, intelligence changes designs password ” , for the space the station escorts the Emperor convoy. Among them, light the fundamental application that quantifying is pair of 3D technologies that print.

The direct of “ day and station of space of future of —— of ” core cabin controls a center, the main room that the spacefarer lives (come from: Spark learns MarsSociety) study the group points out, the structure is light quantifying a design is dimensional station structure in developing a process from beginning to end importunate devises an idea, design group is optimized from structural parameter, develop attacks optimize, the craft of light-duty material application, 3D that print, muti_function the many respects such as the structure are begun decrease serious work. From the diameter the bracket of envelope of 4 meters casing body, wainscot, of all kinds dimension, arrive a metal in beehive board is buried, undertake decreasing weighing designing to each spare parts, the weight in putting forward to written guarantee compose machines a process controls a method, thin body of success of cabin system structure, offerred more embarking opportunities for other equipment and load. Cabin of dream season experiment paragraph structure of lattice of envelope of knot composition of a picture is already mature also use at spacecraft structure product. Small make up still at Beijing space aircraft overall design ministry is in " machinist Cheng journal " a published paper understands, spaceflight closes one kind of 5 courtyards design the equipment that covers portfolio to wrap structure of level of three-dimensional lattice layer supports a construction, heavier than using tradition design and the structure of production method to decrease 46.4% , objective already applied at load of some model satellite to prop up the task. Close the configuration that cheats portfolio to wrap three-dimensional lattice can increase support effectively kind design efficiency of the structure, in spacecraft structure light quantify a respect to have promotion application perspective. “ presses ” firm, make a flight more reliable
Issue more goods and materials to can be installed, “ asks a day ” needs ” of “ thin body, this asks each component is developing his characteristic, will come true through undertaking with the form “ decreases heavy ” . Among them, the join that company place belongs to answer lumber company to make is flexible the composite material truss of solar cell ala, include impaction truss and truss construction two parts, make the product is decreased heft about 30% , promoted experimental cabin to carry the ability of effective load. Regard the “ energy of cabin of experiment asking a day as origin ” , flexible solar cell ala needs to bear in flight process come from a rocket to transmit brought vibration and pressure. For this, development of answer lumber company produced a “ to ask ” of impaction of “ of composite material of day ” exclusive unit, they are not only flexible solar cell ala in experimental cabin two side make safe and reliable “ foundation ” , still can give “ baby ” like caress. Do not see unit of this small “ impaction ” , it is the composite material that enhances body and colophony matrix to mix together by a kind of carbon fiber, have strength tall, density low, quality is light wait for an advantage. Look from the exterior, it is by the impaction truss, impaction that carry a department, composition of armrest impaction truss, be just like in flexible “ base ” removed solid “ foundation ” between solar cell ala and the resource cabin that ask day experiment cabin, will flexible of firmly of solar cell ala fixed go up in resource cabin. In the meantime, avoid oxygen of the atom in getting a space to protect composite material product effectively erode, the whole on structure of outer dew carbon fiber wraps stylist Fu ” of garment of protection of “ of an aluminum foil. In the process of “ clad ” , technology group lets the Fu of aluminum foil level off close to go up in the product through the special type craft of composite material and means of light-duty dotty pressurization, make “ can protect garment ” like silk good each inches of composite material, ensured thereby the product quality of composite material oneself, exhibit “ wing ” to had made adequate preparation to ask day experiment cabin. “ maintained ” to live, make “ more reliable to day ”
What truss structure can be called many meters 20 to join is flexible the “ bridge ” of solar cell ala and directional to day device. In the beginning of design, stylist ever also had considered groovy metal stuff, but while it is enhancing product strength, also grew “ weight ” , bring about ” of “ excess load to run likely. For this, light quantified composite material is favorred again. From this, mix by carbon fiber composite material the truss structure emerge as the times require that beehive board comprises, it realized the rigid join of the equipment outside cabin and directional to day device not only, still bearing the weight of power source subsystem the synchronism of the equipment outside cabin, implementation equipment and directional to day device is rotational, and contented rise paragraph bear the weight of with what work in course requirement. Add transition of innovation of material aftertreatment craft, outstanding target is constant

Limited company of Xi'an spaceflight engine offerred engine of 4 groups of kerosene of 8 120 tons of liquid oxygen to regard as to blast off this aid impetus. Among them also those who add material to make relevant technology is use. This company adds material to make innovation center grind bead to shed the application that processes craft, make surface roughness of surface of flow path of cast of impeller of one class pump reduces 2 times above, promoted the antirust capability of cast effectively, make the performance of turbopump more steady, quality of motor component consign also go up again new chance to extricateoneself from an awkward position. Add material to make innovation center Chen Zhenyu express, this craft changes “ , can saying is to perfect, be our pursuit is reflected outstandingly. ” END

Aerospace is one of key way that powerful nation of current science and technology develops eagerly, its development cannot leave to hold concurrently light quantify, difficult treatment, high-powered the metallic component that waits for a feature. The design that adds material to make a technology be high-powered metal component and production open up new craft approach, in can solving the domain such as aerospace to develop a process, be opposite the material, structure, craft, function and application new challenge that pose. Meanwhile, light quantified material + start new-style design + 3D is printed, this kind of new pattern released a space further again to decrease. Material and structure are made in coordination, arride asks higher to become a possibility, the use of this kind of mode is anounced infrequently also by spaceflight unit.
