NASA Launches High-speed Composite Aircraft Manufacturing Project

NASA tau tshaj tawm cov phiaj xwm kev tsim cov dav hlau sib xyaw ua haujlwm siab

Raws li ib tsab xov xwm tshaj tawm hauv NASA lub vev xaib, txhawm rau nrhiav txoj hauv kev los txhim kho lub dav hlau tshiab kom ruaj khov sai sai, NASA npaj yuav ua tiav qhov kev tsim cov dav hlau sib xyaw ua ke siab ceev (HiCAM). Txoj haujlwm HiCAM yog ib feem ntawm Sustainable Flight National Partnership (SFNP). NASA yuav ua haujlwm nrog nws cov neeg koom tes hauv kev lag luam, kev kawm, thiab tsoomfwv los siv cov thev naus laus zis ntsuab los txhawb txoj kev loj hlob ntawm kev siv dav hlau ntau dua.

Tus thawj saib xyuas haujlwm HiCAM ntawm NASA Langley Research Center tau hais tias yog ib qho ntawm NASA cov haujlwm tshiab kawg, qhov haujlwm HiCAM npaj yuav siv cov ntaub ntawv sib xyaw ua ke rau cov tiam tom ntej ntawm lub dav hlau, uas yuav tsum tau tsim cov chaw tsim khoom lag luam thiab ceev ceev.

Hauv 20 xyoo tom ntej no, lub ntiaj teb kev lag luam dav hlau dav hlau yuav xav tau txog 40,000 dav hlau tshiab kom tau raws li qhov xav tau ntawm huab cua mus ncig, thaum hloov cov dav hlau qub nrog cov dav hlau qub, feem ntau yuav siv rau ib leeg. aircraft kev lag luam lag luam.

Tam sim no, kev tsim khoom ntawm ib leeg-aisle airliners ua los ntawm cov qauv hlau zoo li Boeing 737 airliners yog kwv yees li 60 toj ib hlis. Piv nrog rau cov khoom tsim tau ntawm cov hlau dav hlau, cov khoom tsim tau ntawm cov dav hlau ua los ntawm cov khoom sib xyaw xws li Airbus A220 airliners lossis loj dua Boeing 787 airliners tsis tshaj 14 ib hlis.

Lub hom phiaj ntawm HiCAM qhov project yog txhawm rau ua kom cov txheej txheem tsim khoom no kom ua tiav cov khoom tsim tau ntawm 80 lub dav hlau ib hlis twg siv cov khoom sib xyaw. Txhawm rau ua tiav lub hom phiaj no, cov kws tshawb fawb tab tom kawm txog cov khoom siv sib xyaw thiab cov txheej txheem tsim khoom twg tuaj yeem ua kom nrawm dua li cov khoom lag luam siab, thiab cov khoom siv dav hlau loj dua, xws li cov dav hlau racks thiab airframes, tuaj yeem tsim tau sai dua. Cov khoom no tuaj yeem ua los ntawm cov khoom sib xyaw ua ke xws li yas, graphite thiab ceramics, uas tuaj yeem txo tus nqi ntawm cov qauv sib xyaw, txo qhov hnyav ntawm lub dav hlau, thiab ua tiav cov hom phiaj txuag roj.

NASA tau hais tias cov khoom tsim tau raug txwv los ntawm lub sijhawm nws siv los tsim cov khoom, sib sau ua ke los ua cov khoom dav hlau loj, thiab xyuas cov txiaj ntsig zoo. Tam sim no, feem ntau ntawm cov khoom siv dav hlau ua los ntawm cov khoom siv sib xyaw yog cov khoom siv thermosetting, thiab lawv cov txheej txheem tsim khoom tsis tuaj yeem thim rov qab. Cov khoom sib xyaw ua los ntawm txhua qhov yog kho los ntawm qhov kub thiab txias siab ntawm lub tank kub pressing thiab thaum kawg ua khoom.

Cov txheej txheem tag nrho yog qhov ntev, txog li 8 teev. Txhawm rau kom lub sijhawm luv luv, nws yog qhov yuav tsum tau kawm cov ntaub ntawv sib xyaw uas kho tau sai tshaj plaws hauv lub tank kub xovxwm, cov ntaub ntawv twg tuaj yeem kho tau yam tsis siv lub tank kub nias, thiab seb puas muaj lwm cov ntaub ntawv sib xyaw uas tuaj yeem siv tau. kev tsim khoom.

Pab neeg ua haujlwm HiCAM tseem tab tom ua haujlwm nrog cov koom tes hauv kev lag luam ntawm Advanced Composite Materials Alliance los tsim cov txheej txheem kev tsim cov khoom siv sib xyaw ua haujlwm siab. Cov koom tes hauv kev lag luam no suav nrog cov tuam txhab tsim dav hlau, cov khoom siv thiab software tsim tawm, thiab cov khoom siv. Txawm hais tias lub hom phiaj ntawm HiCAM yog nyob rau hauv kev thauj dav hlau, nws tseem muaj peev xwm siv tau rau lwm yam, suav nrog cov qauv dav hlau me me rau kev thauj mus los hauv huab cua.

Toray Composite Materials America Inc (TCMA) yog lub chaw tsim khoom ntawm TORAYCA ™ carbon fiber thiab aviation-qib thermosetting prepreg. Nws tau koom nrog peb txoj haujlwm ntawm txoj haujlwm ntawm theem no, feem ntau yog lub luag haujlwm rau kev muab khoom ntawm TORAYCA ™ carbon fiber thiab tiam tom ntej ntawm thermosetting prepreg.

Tsis tas li ntawd, TCMA tseem muab cov txheej txheem kev taw qhia rau kev siv cov ntaub ntawv hauv kev txhim kho cov txheej txheem fiber ntau qhov chaw (AFP), kev kho sai, thiab resin perfusion ntawm tis / fuselage qauv. Thermosetting prepreg siv nruab nrab modulus carbon fiber (IM ntxiv) thiab toughened epoxy resin system los muab cov yam ntxwv ntawm cov khoom, cov ntsiab lus tsis tshua muaj resin thiab nruj zog lub cev tsim kev kam rau ua.

Jeff Cross, tus thawj coj ntawm aerospace kev lag luam kev loj hlob ntawm TCMA, tau hais tias: "Peb zoo siab koom nrog ACC txoj kev siv zog los txo cov nqi, txhim kho kev ua tau zoo, thiab nce tus nqi xa khoom ntawm ib leeg-channel lag luam dav hlau, txhawm rau tswj kom muaj kev sib tw kom zoo dua. Tebchaws Asmeskas hauv kev tsim dav hlau. " .

Toray Advanced Composites (TAC) yog cov chaw tsim khoom ntawm ntau yam thermosetting thiab thermoplastic composite cov cuab yeej thev naus laus zis. Nws ncaj qha koom rau hauv plaub qhov ntxiv ntawm qhov project thiab muab cov Cetex ® thermoplastic UD tapes thiab lwm yam khoom siv.

Cov ntaub ntawv no muaj xws li TORAYCA ® carbon fiber reinforced state-of-the-art structural thermoplastic composites nrog tus qauv thiab nruab nrab modulus, thiab siv nyob rau hauv lub tshiab PARTS manufacturing thiab ASSEMBLY PROCESSES. Steve Stop, tus lwm thawj ntawm thev naus laus zis ntawm TAC, tau hais tias: "Toray tau txais txiaj ntsig los txhawb nqa tag nrho cov khoom siv no thiab cov txheej txheem thev naus laus zis los pab kev lag luam aerospace kev lag luam ua tiav qhov tsis tau muaj dua los ntawm 4-6 lub sij hawm tsim khoom loj hlob."
