1.How ua lub zog siab-rau-qhov hnyav piv ntawm txhuas daim hlau txhim kho lub peev xwm lub peev xwm thiab roj kev ua tau zoo?
Txhuas Alloys (piv txwv li, 6061- T6) sib txuasTsawg ntom ntom(~ 2.7 g \/ cm³) nrogHigh tensile lub zog(Txog li 310 mpa).
Satellites yuav tsum tau lub nraweight kom ua kom lub cev hnyav ua rau lub luag haujlwm-tseem ceeb them nyiaj (piv txwv li cov khoom siv sib txuas lus). Los ntawm hloov cov ntaub ntawv hnyav (piv txwv li, hlau) nrog txhuas daim hlau, endiers txuag20-30% Mass, Pub muaj peev xwm pub dawb rau cov payloads ntxiv uas tsis muaj ntau tshaj pob foob pob hluav taws xob hnyav. TusTsiolkovsky Rocket Sib PauvKev tshem tawm uas txo qis satellite txheej txheem loj ncaj qha txo cov roj yuav tsum tau ua kom tiav orbit.
2.What lub luag haujlwm ua cov phiaj txhuas ua si hauv cov kev tswj hwm cua sov rau cov chaw satellite raug rau qhov chaw kub tshaj plaws?
Aluminium'sthermal conductivity(~ 235 w \/ maple ME2 Kev hloov pauv kub los ntawm hotspots (piv txwv li, cov tshuab hluav taws xob, cov tshuab tawm) rau cov cheeb tsam txias lossis txias. Piv txwv li: Aluminium daim hlau ua liThaum Tshav Kub Kub Spellers, Tiv thaiv kev tiv thaiv hauv nroog overheating hauv lub hwj chim loj tshaj plaws lossis hauv cov khoos phis tawj. Aluminium daim hlau feem ntau anodized lossis coated (piv txwv li,Xim dawb, IR-Emissive Tiav) Kom ua kom zooEmissivity(Muaj peev xwm rau cov cua sov ci rau hauv qhov chaw). Piv txwv li: radiators ua los ntawm txhuas daim hlau dissipate nkim kub los yog tseem ceeb rau cov khoom siv hluav taws xob ruaj khov rau hauv cov twj zoo li cov khoom siv kho tshiab.
3.Txhua-desistant-resistant aluminium alloys (piv txwv li, {2}} t6) kom lub sijhawm ntev los nyob hauv lossis ib puag ncig ntev?
Aluminium Lawm Cov Ntawv ANyias, Adherent Oxide Txheej (Al₂o₃)Thaum raug cov pa oxygen, thaiv cov oxidation ntxiv. Hauv qhov chaw, txheej txheej txheej txheem kev kho tus kheej yog tias puas los ntawm micrometeoroids lossis khib nyiab, tiv thaiv cov khoom siv cov khoom nqus. Aluminium lub oxide txheej qhia txogUV hluav taws xob, Tiv thaiv polymer-zoo li emnittlement. Alloys zoo li 6061- t6 tuav cov cuab yeej cuab tam sim no txawm hais tias ntev ntev raug rau Cosmic rays. Tsis zoo li cov hlau, aluminium alloys tsis xeb hauv av noo (piv txwv li, thaum lub sij hawm sib dhos lossis pob zeb cia). Post-Tua tawm, lub tshuab nqus tsev ntawm qhov chaw tshem tawm cov dej noo, tab sis pre-up-repor corrosion resistance ensures kev ntseeg tau.
4. Tsoo txoj kev machinable tshuab txiav yooj yim muab fabrication ntawm cov nyom satellite qauv qauv?
Complex geometry kev paub tseeb txhuas lub tshuab raj sib xyaw ua ke ntawm cov ntsiab lus tsis zoo.}} Aycingide cov ntsiab lus tsis muaj zog.<1 mm) that are critical for compact satellite designs. Optimized material removal rates leverage aluminum's Kev Tsawg Txiav Kev, Txo kev siv hluav taws xob los ntawm 30-40% piv rau titanium machining.
5.Vim li cas txhuas lub chaw tiv thaiv cov khoom tseem ceeb rau kev tiv thaiv satellite electronics los ntawm cosmic hluav taws xob?
Thaum lub sij hawm txhuas ib leeg tsis tuaj yeem thaiv lub zog loj ionizing ionizing ordizing hais (piv txwv li, hnyav ions), nws em shielding: txoThib Ob Hluav Taws Xob(Xws li, xoo hluav taws xob, bremsstrahlung) tsim tawm thaum Cosmic Rays tawm tsam satellite qauv. MinimizesKev xaiv khoom hluav taws xob hloov pauvNyob rau hauv lub voj voog tshwm sim los ntawm electromagnetic txuas los ntawm particle strikes.Starhlink SatellitesSiv cov thaiv txhuas alloy rau Shield pased pased-array anten-arcels los ntawm kev ua suab nrov hnub ci thaum tswj cov cim kev ncaj ncees. James WebB Chaw Rau Telescope tusAluminium-coated hnub ci ntsa iab thaiv infrared kev cuam tshuam los ntawm lub hnub thiab lub ntiaj teb.
