Fabkis 3D luam ntawv thawj cov cuab yeej tsim khoom (OEM) thiab cov chaw muab kev pabcuam 3DCeram tau raug xaiv los ua tus neeg xa khoom ntawm Fabkis qhov chaw propulsion chaw tsim tshuaj paus ThrustMe los muab 3D luam tawm ceramic qhov chaw rau nws qhov chaw propulsion system.
Tam sim no ThrustMe yuav nrhiav kev txhawb nqa 3DCeram qhov kev txawj ntse hauv ceramic additive manufacturing thiab coj mus rhaub rau hauv lub peev xwm ntawm cov khoom siv ceramic rau kev siv dav hlau. ThrustMe txoj hauv kev rau 3D luam ntawv ceramics lub hom phiaj kom kov yeej cov kev txwv ntawm cov khoom siv thiab cov txheej txheem. Lub tuam txhab thov hais tias ceramic additive manufacturing muaj ib tug ntau compact, npaum thiab txhim khu kev qha kev daws teeb meem tshaj li niaj hnub manufacturing.
3DCeram Tus Sawv Cev Muag Khoom Arnaud Roux tau hais tias: "Rau 3DCeram, peb zoo siab rau peb txoj kev koom tes nrog ThrustMe, raws li kev ua tiav ntawm 3D luam tawm ceramic tivthaiv rau hauv qhov chaw yog qhov tseem ceeb hauv kev siv cov khoom siv ntxiv. Nws kuj yog ib lub sijhawm tshiab. Nyob rau hauv uas complex thiab kev cai qhov chaw yuav ua tau zoo tsim mus tshaj li ib txwm raug txwv. Qhov kev ua ntej loj no tsis tsuas yog siv tau qhov kev muaj peev xwm ntawm 3D luam ntawv raws li cov cuab yeej tsim khoom, tab sis txhawb peb mus ntxiv thiab qhib qhov muaj peev xwm loj ntawm lub neej yav tom ntej.

ThrustMe hloov mus rau kev tsim khoom ntxiv
Founded hauv 2017, ThrustMe tau dhau los ua ib tus neeg tseem ceeb hauv qhov chaw tshiab, tshwj xeeb hauv kev ua haujlwm me me ntawm cov tshuab hluav taws xob propulsion.
Lub sijhawm "chaw tshiab" yog hais txog kev tsim kho tshiab thiab kev nce qib hauv qhov chaw lag luam uas tau tsav los ntawm cov tuam txhab ntiag tug. Raws li Elena Zorzolli Rossi, Tus Thawj Saib Xyuas Khoom Muag ntawm ThrustMe, kev lag luam ntawm qhov chaw tau raug tsav los ntawm kev nce qib ntawm kev siv technology sai. Zorzolli Rossi hais tias cov tuam txhab yuav tsum muaj kev pheej hmoo ntau dua, rov hais dua sai sai thiab sim cov tswv yim tshiab los txhim kho qhov chaw lag luam ntxiv. Zorzolli Rossi tau hais ntxiv tias: "Tag nrho cov saw hlau yuav tsum tau npaj kom tau raws li qhov chaw tshiab lossis lub sijhawm xa khoom."
Xyoo 2020, ThrustMe tau ua tiav pom lub ntiaj teb thawj iodine-fueled electric propulsion system hauv qhov chaw. Tam sim no ThrustMe muab khoom siv feem ntau rau cov satellite launchers loj thiab tau qhib qhov chaw tsim khoom tshiab uas muaj peev xwm tsim tau 365 cov khoom hauv ib xyoos.
Raws li Zorzolli Rossi, tom qab kev tshawb fawb thiab kev tshawb fawb ntev, ThrustMe tau xaiv siv 3D luam ntawv los tsim cov khoom tshwj xeeb hauv thruster. Qhov kev txiav txim siab no tau coj mus rau hauv tus account ntau yam uas ua rau kev tsim khoom ntxiv zoo dua rau cov txheej txheem tsim khoom.
Zorzolli Rossi piav qhia tias: "Ua ntej tshaj plaws, kev lag luam aerospace feem ntau xav tau tsim cov duab nyuaj uas tsis tuaj yeem yooj yim tau los ntawm cov txheej txheem machining ib txwm. Nyob rau hauv rooj plaub no, 3D luam ntawv muaj kev hloov pauv los tsim cov qauv tsim tshwj xeeb nrog qhov tseeb peb xav tau. "
Tsis tas li ntawd, ntau yam ntawm 3D luam ntawv yog suav tias yog qhov txiaj ntsig tseem ceeb, tso cai rau cov tuam txhab rov hais dua thiab kho cov qauv tsim sai sai yam tsis muaj nqi tseem ceeb lossis lub sijhawm ua haujlwm.
Zorzolli Rossi tau hais tias: "Cov txheej txheem tsim khoom ib txwm muaj feem ntau koom nrog kev tsim cov pwm lossis cov cuab yeej siv, uas tuaj yeem siv sijhawm ntev thiab kim. Nrog 3D luam ntawv, peb tuaj yeem tsim cov qauv tsim thiab iterate cov qauv tsim nrog lub sij hawm tsim tsawg, ua kom yooj yim rau kev txhim kho cov txheej txheem thiab ua kom peb lub sijhawm ua lag luam. "

Vim li cas thiaj siv ceramics?
Zorzolli Rossi tau hais tias: "Peb tau soj ntsuam ntau yam ua ntej xaiv cov khoom siv ceramics. Kev siv cov ceramics coj mus rau hauv tus account ntau yam tseem ceeb ntsig txog qhov chaw hnyav xws li lub tshuab nqus tsev thiab qhov kub thiab txias, nrog rau iodine plasma cov yam ntxwv tshwj xeeb ntawm cov propulsion ntau. systems (xws li lub zog siab flux ntawm lub hauv paus ntsiab lus, theem nrab emission, khaus sputtering thiab reactive ion etching).
Thaum kawg, qhov kev txiav txim siab tseem ceeb cuam tshuam qhov kev txiav txim siab no tau ua nrog ib puag ncig uas lub hom phiaj yuav khiav. Zorzolli Ross piav qhia tias: "Ib txhia ntawm peb cov khoom tau raug kub hnyiab hauv cov tshuaj lom neeg plasma ib puag ncig thiab xav tau cov khoom siv nrog thermal thiab tshuaj tiv thaiv zoo heev. yog qhov kev xaiv tsim nyog tshaj plaws."
Qhov dav thermal conductivity ntawm ceramics kuj ua rau lawv muaj kev xaiv zoo nkauj. Qhov tseeb, kev hloov hluav taws xob tau zoo thiab kev sib cais thermal yog qhov tseem ceeb rau ThrustMe cov khoom. Qhov no pab ncaj qha tshav kub flux zoo thiab tiv thaiv overheating los yog txias. Ceramics muaj ntau yam ntawm cov khoom siv hluav taws xob, tso cai rau kev xaiv cov cua sov hloov pauv thiab ua kom muaj kev ua tau zoo ntawm cov khoom no.
Cov khoom hluav taws xob ntawm ceramics kuj tau ua lub luag haujlwm tseem ceeb hauv ThrustMe cov txheej txheem xaiv cov khoom. Zorzolli Ross tau hais tias: "Peb cov khoom xav tau cov khoom siv uas tuaj yeem sib cais tau zoo thiab tiv thaiv cov hluav taws xob hluav taws xob siab. Ceramics muaj cov khoom siv hluav taws xob zoo heev, ua rau lawv zoo tagnrho rau kev ua tau raws li peb cov kev cai nruj hauv qhov no."

Chaw Ceramics 3D Printing
Xyoo tas los, Lub Chaw Haujlwm Fab Kis Fab Kis tau tshaj tawm tias nws tab tom tshawb nrhiav daim ntawv thov ntawm ceramic 3D luam ntawv hauv kev ua kom zoo ntawm qhov chaw subsystems. Tshwj xeeb, cov kws tshawb fawb tau soj ntsuam seb 3D luam ntawv oxide ceramic cov ntaub ntawv tuaj yeem txhim kho qhov tsim ntawm cov txheej txheem tseem ceeb rau qhov chaw propulsion.
Txoj kev tshawb no qhia tau hais tias optimized yttrium aluminium garnet (YAG) xerogels muab lub zog xav tau thiab nkag siab zoo thaum 3D luam tawm rau hauv cov duab nyuaj. Yog li, 3D luam tawm YAG ceramics tuaj yeem siv los ua lub hauv paus ntawm cov hlau alloys siv rau yav tom ntej turbine hniav rau kev tshawb nrhiav qhov tob tob.
Tsis tas li ntawd, International Chaw Chaw Nres Nkoj (ISS) tau nruab nrog MadeIn Space's ceramic additive manufacturing facility, Turbo Ceramic Manufacturing Module (CMM). Cov qauv no suav nrog SLA 3D tshuab luam ntawv los ua kom pom qhov ua tau ntawm kev tsim cov khoom siv ib puag ncig ceramic turbine hauv ib puag ncig microgravity. Nws tau hais tias yog thawj SLA 3D tshuab luam ntawv los ua haujlwm hauv orbit.
