Kevin Michaels, tus thawj coj ntawm AeroDynamic Advisory, lub tuam txhab pabcuam kev pabcuam kev pabcuam, tau tshaj tawm lub suab ceeb toom los ntawm kev hais tias Lavxias Thawj Tswj Hwm Putin tuaj yeem kaw kev lag luam aerospace kev lag luam yog tias nws xaiv ua li ntawd.
VSMPO-AVISMA Corporation raws li nyob rau hauv Verkhnyaya Salda, Russia, yog lub ntiaj teb no tus loj tshaj plaws titanium tsim. Nws muab 30-35 feem pua ntawm cov titanium siv los ntawm aviation sector thoob ntiaj teb. Aerospace giants xws li Boeing thiab Airbus muaj ntau nyob ntawm Lavxias teb sab titanium.
"Nws nyuaj kom tau txais cov lej raug. Raws li The Air Current, lawv (VSMPO) muab 35 feem pua ntawm Boeing titanium, 65 feem pua ntawm Airbus, thiab 100 feem pua ntawm Embraer,"haisMichaels ntawm lub rooj sib tham khoom muag thaum Lub Ob Hlis.

Nyob rau xyoo 1950, thaum txoj kev loj hlob ntawm cov dav hlau supersonic pib, cov tuam txhab aerospace pib siv titanium alloys raws li cov qauv txhuas hlau tsis tuaj yeem ua tau raws li qhov xav tau tshiab.
CovLockheed SR-71 'Blackbird'
Ib qho tseem ceeb tshaj plaws thaum ntxov daim ntawv thov ntawm titanium yog nyob rau hauv lub Lockheed SR -71 'Blackbird' lub tswv yim tshawb nrhiav aircraft, uas tau siv ntau heev los ntawm US cov neeg soj xyuas lub koom haum CIA tawm tsam Soviet Union ntawm lub ncov ntawm Tsov Txias.
CIA muajua ntejnpaj rau kev siv Lockheed's U-2, ib qho qeeb qeeb ib lub dav hlau dav hlau siab siab tshawb nrhiav dav hlau rau lub hom phiaj no, tso siab rau qhov kev ntsuas tsis zoo uas Soviet radar thiab cov foob pob hluav taws tiv thaiv tsis tau ua haujlwm ntawm qhov siab tshaj ntawm ntau dua 70, 000 ko taw.
Txawm li cas los xij, U-2 thawj lub davhlau hla USSR tau pom tias Soviet radar tuaj yeem taug qab lub dav hlau. CIA pom tau hais tias nws yog ib qho teeb meem ntawm lub sij hawm ua ntej U-2 yuav tsis muaj peev xwm overfly lub Soviet Union.
Qhov no tom qab ntawd los muaj tseeb nyob rau lub Tsib Hlis 1960, thaum US Air Force pilot Francis Gary Powers ya U-2 tob rau hauv lub tebchaws Soviet raug tua los ntawm S-75 Dvina (SA-2} " Cov lus qhia") foob pob hluav taws saum npoo av-rau-huab cua hla Sverdlovsk (tam sim no-hnub Yekaterinburg).
Lub SR-71 'Blackbird' (cov ntaub ntawv duab / Wikimedia Commons)Lub caij no, ob xyoos ua ntej qhov xwm txheej, CIA tau pib tsim SR-71 nrog lub hom phiaj ntawm kev ua tau raws li ob qho tseem ceeb - qhov qis radar hla ntu thiab nrawm heev!
CIA xav kom SR-71 ya ntawm Mach 3 ntxiv rau qhov nrawm - ntau dua 3 npaug ntawm lub suab nrawm - uas tau khi ua kom muaj cua sov ntau. Tsis tas li ntawd, qhov qis radar cross-section txhais tau hais tias kev siv radar-absorbing composites ntawm cov npoo taw qhia (lossis "chines") ntawm lub dav hlau lub fuselage, uas tseem xav tau kom muaj peev xwm tiv taus cua sov.
Aluminium tsis tuaj yeem siv vim nws qhov kub thiab txias. Cov hlau raug txiav tawm vim nws qhov hnyav - tsuas yog cov khoom siv qis tuaj yeem ua kom muaj kev kub ceev. Yog li, Lockheed tau xaiv Titanium rau SR-71, vim nws yog qhov sib dua tsis tau muaj zog dua, thiab tuav txog qhov kub thiab txias, thaum tso cai rau cov dav hlau ya sai dua.
Vim li cas thiaj xaiv Titanium
Titanium muaj zog npaum li hlau tab sis 45 feem pua sib dua. Nws tuaj yeem siv los ua cov khoom siv rau qhov kub ntawm roughly 1000 mus rau 1150 degree F, whereas pa aluminium alloys tsuas yog pab tau txog li 350 degree F. Nws kuj tau pom tias muaj kev tiv thaiv zoo heev thiab qaug zog.
Txawm li cas los xij, titanium cov cua sov ua haujlwm uas ua rau nws tsim nyog rau kev ya davhlau siab, kuj ua rau nws nyuaj heev rau kev ua haujlwm rau hauv cov duab uas xav tau. Txawm tias rho tawm titanium los ntawm cov ntaub ntawv raw thiab tom qab ntawd tuav nws hauv nws daim ntawv ntshiab yog qhov nyuaj heev.
Yog li, Lockheed yuav tsum tau tsim txoj hauv kev ntawm kev ua thiab tuav cov khoom. Txawm tias me ntsis kev hloov pauv ntawm qhov kub thiab txias hauv huab cua ntawm nws qhov chaw tsim khoom tuaj yeem ua rau tag nrho cov khoom ntawm titanium puas.
Qhov kev sib tw tseem ceeb yog tau txais cov Titanium ntau txaus rau kev tsim tawm tag nrho ntawm 32 SR-71s. Qhov no yog txoj kev rov qab rau xyoo 1950, thaum US 'arch-rival, lub Soviet Union, kuj yog thawj qhov chaw thiab ib tug thawj exporter ntawm Titanium.
Ben Rich, Lockheed tus thawj coj aerodynamicist rau SR-71, piav qhia seb lub tuam txhab tau txais titanium nws xav tau li cas:

"Peb cov khoom lag luam, Titanium Metals Corporation, tsuas muaj qhov txwv tsis pub muaj txiaj ntsig ntawm cov hlau tsis muaj txiaj ntsig, yog li CIA tau tshawb nrhiav thoob ntiaj teb thiab siv cov neeg thib peb thiab cov tuam txhab dummy, tswj kom tsis txhob yuav cov hlau los ntawm ib qho ntawm lub ntiaj teb ua lag luam xa tawm - Soviet Union. . Cov Russians yeej tsis muaj ib qho inkling ntawm yuav ua li cas lawv yeej pab rau lub creation ntawm lub dav hlau raug rushed mus rau hauv kev tsim kho mus soj ntsuam nyob rau hauv lawv lub teb chaws."
Nyob rau tib lub sijhawm, kev siv titanium hauv aviation tau loj hlob nrog cov qauv dav hlau tshiab tau nce ntxiv rau cov khoom siv hnyav.
Cov tiam tshiab ntawm US-ua tub rog aircraft xws li F-22 Raptors thiab F-35 tau siv ntau ntxiv ntawm titanium, tshwj xeeb tshaj yogtom qab 2000. Titanium kuj tseem siv tau rau tsheb armor thiab thav duab, nrog rau cov khoom siv hauv nkoj nkoj.
Muab nws qhov tseem ceeb, tsoomfwv Meskas tau xaiv titanium ua ib qho ntawm 35 yam khoom ntawm nws 'Critical Mineral List.
Lub caij no, ntau lub ntiaj teb titanium ore tseem tuaj ntawm Russia, thaum lwm qhov chaw suav nrog Tuam Tshoj, Kazakhstan, thiab Nyiv.
