Yuav ua li cas Titanium Alloys Fais Fab Lub Satellite Lightweight Revolution?

Lub teeb yuag tsim tau dhau los ua qhov tseem ceeb rau kev ua haujlwm satellite, tus nqi thiab kev lag luam kev sib tw.Titanium alloys muaj lub zog tshwj xeeb, huab cua tsis kam thiab lub neej ua haujlwm ntev kom tawg los ntawm kev txwv ntawm cov khoom siv ib txwm muaj. Lawv ua cov khoom tseem ceeb rau kev txo qhov hnyav thiab txhim kho kev ua haujlwm ntawm satellites, kev txhim kho cov khoom siv thiab kev ua haujlwm ntawm aerospace manufacturing.

 

 

Satellite hnyav ncaj qha txiav txim rau tus nqi xa tawm, lub peev xwm thauj khoom thiab lub neej orbital. Txhua 1 kg ntawm qhov hnyav txo txuag kwv yees li 20,000 US las hauv cov nqi pib, thaum ua kom muaj kev sib koom ua ke ntau dua thiab ua haujlwm ntev dua. Cov tsoos aluminium alloys thiab steels yog tsawg- nqi tab sis pheej ua tsis tiav nyob rau hauv qhov chaw huab cua, nrog rau qhov kub thiab txias hloov ntawm -200℃rau +500 degree, muaj zog hluav taws xob thiab atomic oxygen, ua rau lawv tsis tuaj yeem ua tau raws li qhov ntev - lub neej thiab kev ntseeg siab.

 

Raws li LEO satellite constellations txav mus rau qhov loj - nplai, me me thiab siab - dhau los ntawm kev txhim kho, cov ntaub ntawv yuav tsum tau ualub teeb, muaj zog, ruaj khov thiab ruaj khovnrog nruj nruj thiab ib puag ncig adaptability qauv. Titanium alloys yog qhov kev xaiv zoo tshaj plaws.

 

 

1. Muaj zog tshwj xeeb rau qhov kawg qhov hnyav txo

BDS-3 txais qib 5 titanium alloy rau nws cov qauv tseem ceeb, ua tiav ntau dua 15% qhov hnyav txo thiab 15% siab dua lub peev xwm.

Qhov zoo tshaj plaws titanium alloy bracket rau cov chaw taws teeb sensing satellite txiav 173 kg ib satellite, txuag tshaj 3.4 lab US las hauv cov nqi pib.

 

2. Kev hloov mus rau qhov chaw ib puag ncig huab cua

Kev pabcuam kub yog li ntawm -269℃txog 550℃nrog cov khoom siv kho tshuab ruaj khov, zoo tshaj plaws rau aluminium alloys, sib piv tag nrho qhov kub hloov pauv ntawm kev lag luam satellite.

 

Lub oxide zaj duab xis tiv taus atomic oxygen thiab propellant corrosion, muaj zog hluav taws xob tiv thaiv, txhawb 10-15 xyoo hauv - kev pabcuam orbit.

Tsawg coefficient ntawm thermal expansion thiab siab stability, haum rau precision Cheebtsam xws li optics thiab antennas.

 

3. Lub neej ntev thiab kev ntseeg siab rau lub neej qis dua -Cov nqi voj voog

Titanium alloys muaj ntau dua 50% lub neej qaug zog ntev dua li txhuas alloys, tsis yog - sib nqus thiab tsis muaj qhov txias vuam hauv lub tshuab nqus tsev, ua tau raws li xoom- kev tu vaj tse ntawm satellites. Txawm hais tias cov khoom siv ntau dua, lawv muab cov txiaj ntsig zoo ntawm kev lag luam tag nrho vim qhov tsis ua haujlwm tsawg, kev ua haujlwm ntev thiab kev saib xyuas tsawg.

 

 

Titanium alloys yog siv nyob rau hauv me me tab sis siab - tus nqi kom muaj nuj nqis nyob rau hauv satellites, accounting rau 5% -15% ntawm tag nrho cov satellite loj thiab 30% -40% ntawm cov core structural qhov chaw.

 

1. Thawj Load-Cov Qauv Kabmob

Raws li lub cev pob txha tseem ceeb ntawm satellites, thawj qhov kev thauj khoom -cov kabmob thooj voos kheej kheej, cov hlua khi thiab lub platform thav duab feem ntau siv siab -lub zog titanium alloys, ua tiav lub teeb yuag thiab siab load peev los ntawm nyias- phab ntsa sib xyaw tsim.

Ib qho corrugated titanium alloy load-cov kabmob cone seem rau satellite halved hnyav thiab nce load kuj los ntawm 80%.

Lub koom haum 725 tau tsim ib lub 3.7-meter titanium alloy thawj cov kabmob uas muaj cov phab ntsa tuab ntawm 4 hli, paub txog 30% qhov hnyav tag nrho.

 

2. Propulsion thiab Thermal Control Systems

Roj tso tsheb hlau luam, lub cav nozzles, li qub thiab lwm yam khoom siv siab - kub titanium alloys xws li Ti-6Al-4V, muaj peev xwm tiv taus 500℃kub thiab tiv thaiv corrosion. Cov kav dej kub thiab cov cua txias tau txais Ti-3Al-2.5V titanium alloy, uas muaj cov thermal conductivity tsawg thiab lub tshuab nqus tsev zoo heev.

 

3. Cov kav hlau txais xov thiab cov qauv them nyiaj

Kav hlau txais xov brackets, kho qhov muag platforms thiab tej thaj chaw deb sensing khoom enclosures feem ntau siv 3D- luam titanium alloy lattice qauv, ua tau raws li qhov hnyav txo thiab kev sib sau ua ke.

 

Lub bracket satellite tau optimized los ntawm 6.0 kg khoom ib feem mus rau 3.6 kg lattice qauv, txiav hnyav los ntawm 40% thaum tuav lub peev xwm load.

 

4. Txheem qhov chaw thiab fasteners

Titanium alloy bolts, txiv ntseej, gaskets thiab lwm yam ua tiav "gram-qib qhov hnyav txo". Nrog lub zog siab thiab qaug zog, lawv txo qhov hnyav los ntawm ob peb kilograms ib satellite thiab zam qhov hnyav nce ntawm cov hlau.

 

 

Kev sib xyaw ua ke ntawm 3D luam ntawv thiab titanium alloys tawg los ntawm cov kev txwv ntawm kev ua ib txwm ua thiab paub txog lub teeb yuag:

 

• AI-tsim qauv bionic lightweight configurations txhim kho cov khoom siv mus rau ntau tshaj 90% thiab txo qhov hnyav los ntawm 30% -50%.

 

• Ntau qhov chaw raug luam tawm hauv ib kauj ruam, txo cov vuam thiab kev sib dhos tsis zoo thiab txhim kho kev ntseeg tau zoo.

 

• Lub me me -batch ntau lawm voj voog ntawm satellite Cheebtsam yog luv luv los ntawm lub hlis mus rau lub lis piam, yoog raws li qhov xav tau ntau lawm ntawm kev lag luam aerospace.

 

 

• Hauv tsev qis- cov khoom siv titanium nqi tau raug siv, nrog rau cov nqi txo los ntawm 30%, thiab tus nqi saws me nyuam hauv kev lag luam satellites tau nce sai.

 

• High-kawg titanium alloys los ntawm kev lag luam xws li Baoti Group thiab Western Superconducting muaj kev txhawb nqa ntau dua 30% hauv kev lag luam satellites, txhawb nqa cov haujlwm loj xws li BDS thiab Tuam Tshoj SatNet.

 

• Kev nthuav dav los ntawm cov txheej txheem mus rau qhov chaw ua haujlwm xws li kev tswj xyuas thermal, ntim khoom siv hluav taws xob thiab cov kav hlau txais xov, nrog rau qhov kev faib ua feem ntawm tag nrho cov satellite loj yuav tsum ncav cuag 8% -12%.
