Kev siv titanium hauv cov dav hlau niaj hnub thiab cav?
Niaj hnub nimno aircraft thiab cav nyob rau hauv qhov tseem ceeb ntawm high-temperature alloy, aluminium alloy, titanium alloy, ultra-siab zog steel, composite cov ntaub ntawv thiab lwm yam tsib pawg ntawm cov khoom siv. Titanium feem ntau yog siv nyob rau hauv cov nram qab no yam ntawm aircraft:
1. Titanium alloy khoom rau aircraft qauv
Titanium alloy muaj ntau qhov zoo xws li lub zog tshwj xeeb, zoo corrosion kuj thiab kub tsis kam, thiab tuaj yeem siv ntau txoj hauv kev ntawm kev tsim, vuam thiab machining, yog li nws tau siv dav hauv cov dav hlau thiab cov cav. Niaj hnub no, feem pua ntawm titanium alloy nyob rau hauv qhov hnyav ntawm cov qauv dav hlau tau dhau los ua ib qho tseem ceeb ntsuas ntsuas cov qib siab ntawm cov khoom siv dav hlau. Titanium ua 39 feem pua ntawm cov qauv hnyav ntawm F-22. Daim ntawv thov ntawm Baoji titanium anode titanium alloy nyob rau hauv txawv teb chaws civil aircraft kuj nce nrog kev txhim kho ntawm aircraft tsim thiab qib kev ua tau zoo. Kev puas siab puas ntsws ua tau zoo yog qhov tseem ceeb ntawm cov khoom siv kev ua tau zoo rau lub neej ntev, kev txav mus los siab, tus nqi qis thiab kev puas tsuaj rau kev tsim qauv ntawm cov tiam tshiab fighter dav hlau (xws li lub siab thrust ratio engine). Tebchaws Asmeskas ua tus thawj coj hauv kev ua tiav kev siv lub tswv yim tsim kev nyab xeeb kev puas tsuaj thiab kev puas tsuaj rau kev tsim qauv rau cov dav hlau dav hlau siab tshaj. F-22 fighter aircraft txais ntau qhov kev puas tsuaj rau titanium alloy thiab nws cov khoom tseem ceeb kom ua tau raws li cov qauv tsim ntawm qhov hnyav poob thiab lub neej ntev. Ti-6Al-4VELI tau siv nyob rau hauv qhov loj tshaj forgings ntawm American C-17 tub rog thauj dav hlau. Baoji titanium anode siab zog titanium alloy Ti-6-22-22S kuj tau siv rau hauv qhov tseem ceeb ntawm C-17 aircraft xws li kab rov tav tail sib koom (rotating ncej). Kev siv ob lub titanium alloys no ua rau lub neej ntawm cov dav hlau thauj loj mus txog 60, 000 teev davhlau lossis ntau dua. Hauv Tebchaws Europe, Airbus A380 yog thawj lub dav hlau uas muaj tag nrho-titanium pylon, uas yuav siv rau yav tom ntej A350s.
2. Kub kub titanium alloy rau aeroengine
Kub kub titanium alloy yog tsuas yog siv nyob rau hauv lub tsim ntawm aero-engine compressor hniav, discs, casing thiab lwm yam, uas yuav tsum tau cov ntaub ntawv uas muaj lub zog tshwj xeeb, creep kuj nyob rau hauv high kub, qaug zog lub zog, kav ntev zog thiab lub koom haum stability nyob rau hauv kub kub ua hauj lwm. Cov xwm txheej (300 ~ 600 degree). Nrog rau qhov nce ntawm thrust-qhov hnyav piv ntawm aero-engine, kev khiav hauj lwm kub ntawm high kub titanium alloy hniav thiab discs nce nrog qhov nce ntawm qhov hluav taws xob kub ntawm lub siab compressor. Tom qab ntau xyoo ntawm txoj kev loj hlob, lub siab ua hauj lwm kub ntawm cov khoom siv ntxiv dag zog rau qhov kub thiab txias titanium alloy tau nce los ntawm 350 degree mus rau 600 degree. Lub siab kub titanium alloy TC4 thiab TC6 yog tsuas yog siv nyob rau hauv lub aero engine nrog lub ua hauj lwm kub hauv qab no 400 degree, uas yog siv nyob rau hauv lub engine uas tsis muaj ua hauj lwm kub ntawm kiv cua thiab compressor hniav ntawm thawj thiab thib ob theem. Qhov kub kub titanium alloys ua haujlwm nyob ib ncig ntawm 500 degree suav nrog TC11, TA15 thiab TA7 alloy, ntawm cov TC11 yog cov titanium alloy siv hauv peb lub tshuab aeroengine tam sim no. Nws yog ib qho nyuaj rau ua tau raws li qhov yuav tsum tau ntawm creep kuj thiab lub zog ntawm qhov kub siab tshaj 600 degree rau titanium alloy tsuas yog ntxiv dag zog los ntawm cov khoom tov. Vim nws lub zog tshwj xeeb, nruj nruj, siab creep tsis kam, zoo heev oxidation kuj thiab nplaim retardant zog, kom muaj zog Ti-Al intermetallic tebchaw tau dhau los ua cov neeg sib tw muaj peev xwm siv tau ntawm qhov kub siab tshaj 600 degree. Ti3al-raws li alloys ua haujlwm ntawm 650 degree rau lub sijhawm ntev, thaum TiAl alloys ua haujlwm ntawm 760 degree ~ 800 degree.
3. Aircraft titanium alloy fasteners
Titanium alloy fasteners tuaj yeem txo qhov hnyav ntawm lub dav hlau, tuaj yeem tsis tsuas yog txhim kho kev ua haujlwm ntawm lub davhlau, tab sis kuj txo tus nqi ntawm kev siv, lub ntsiab yog txo cov roj noj. Kwv yees li 200, 000 titanium alloy fasteners yog xav tau rau txhua tus ntawm Tuam Tshoj lub tsev c919 aircraft, nrog 20 lab xav tau los ua kom tiav thawj 100 qhov kev txiav txim pib. Nrog rau kev npaj tsim tawm ntawm 150 lub dav hlau loj los ntawm 2018, 30 lab titanium fasteners yuav xav tau txhua xyoo. Titanium alloy fastener txoj kev loj hlob muaj peev xwm loj, kev lag luam kev loj hlob zeem muag zoo heev.
Tuam Tshoj txoj kev dav hlau dav hlau yuav tsum ncav cuag 6,309 thaum kawg ntawm 2031, 3.6 npaug ntawm qhov loj tam sim no. Vim yog cov yam ntxwv ntawm Tuam Tshoj txoj kev dav hlau txoj kev network qauv, yav tom ntej fleet muaj pes tsawg leeg tseem yuav tau dominated los ntawm ib leeg-channel trunk aircraft, tab sis qhov feem ntawm dav-lub cev lub cev dav hlau thiab lub regional aircraft yuav nce. Tuam Tshoj yuav xav tau 4,933 tus neeg caij dav hlau ntxiv rau hauv 20 xyoo tom ntej vim tias kev loj hlob thiab kev hloov pauv xav tau los ntawm kev tshem tawm. Cov kws tshaj lij hais tias nyob rau lub sijhawm ntev, Tuam Tshoj txoj kev lag luam ruaj khov, kev loj hlob hauv nroog thiab kev hloov kho cov neeg siv khoom yuav ua rau muaj txiaj ntsig zoo rau kev loj hlob ntawm huab cua thauj mus los. Cov nqi roj siab thiab kev tiv thaiv ib puag ncig nruj kuj tseem ua rau cov dav hlau ua kom cov dav hlau so haujlwm ntawm lub dav hlau qub. Txhawm rau txhawm rau txhim kho kev lag luam ntawm pej xeem dav hlau, 10 xyoo tom ntej no yuav yog lub sijhawm tseem ceeb rau kev loj hlob leapfrog ntawm Suav aviation kev lag luam, thiabtitanium kev lag luam yuav ntsib lub sijhawm tsis tshua muaj rau kev txhim kho.
