Aerogels hauv Aerospace

Aerogels sawv cev rau kev ua tiav hauv thermal rwb thaiv tsev thev naus laus zis. Lawv yog lub teeb yuag, muaj kev ua haujlwm siab thermal rwb thaiv tsev, thiab muaj kev hloov pauv yooj yim. Cov yam ntxwv no ua rau lawv tsis muaj qhov tseem ceeb hauv kev siv aerospace, qhov chaw ua haujlwm, kev ua haujlwm, thiab qhov hnyav yog txhua yam tseem ceeb.

Vim li cas Airgel rau Aerospace

Airgel rwb thaiv tsev tau siv ntau dua hauv kev siv aerospace qhov twg qhov hnyav txo, thermal stability, thiab qhov chaw ua haujlwm tau zoo yog qhov tseem ceeb rau lub dav hlau thiab satellite systems.

Spacecraft thermal tiv thaiv system: airgel yog siv los ua rwb thaiv tsev txhaws lossis tiv thaiv kom tsis txhob kub hloov pauv thiab hluav taws xob. Piv txwv li, Shenzhou 16 siv nws rau sau thiab rwb thaiv tsev, thiab Tianwen 1 siv 10mm cov khoom los thaiv qhov kub siab tshaj 1000 degree.

Aircraft engine rwb thaiv tsev: siv rau cov rwb thaiv tsev kub ntawm siab - qhov kub ntawm lub cav. Lub Peb Hlis Ntuj 5B lub foob pob hluav taws lub cav roj siv cov nano airgel xav kom cais cov cua sov thiab tiv thaiv cov khoom siv hluav taws xob.

Aerospace cov cuab yeej rwb thaiv tsev: Tianzhou 1 thiab 4 siv nws ua lub tshuab nqus tsev rwb thaiv tsev thiab cov khoom siv rwb thaiv tsev; Mars rovers cia siab rau airgel kom cov khoom siv hluav taws xob thiab cov hluav taws xob khiav ntawm qhov kub qis.

Lwm yam kev siv: siv rau lub dav hlau cabin phab ntsa thiab cov cuab yeej rwb thaiv tsev, xws li US "Osprey" thiab British "Jaguar"; airgel yog siv rau rwb thaiv tsev ntawm qhov chaw suit interlayers los tiv nrog huab cua kub.

Aerospace Application Scenarios

Cov ntaub ntawv Airgel tau siv thoob plaws ntau lub tshuab hluav taws xob hauv aerospace, suav nrog cov cua sov rwb thaiv tsev, satellite kub tswj, thiab kev tiv thaiv-txog ib puag ncig uas xav tau lub teeb yuag thiab siab - cov ntaub ntawv ua tau zoo.

Cov Khoom Tseem Ceeb

Cov kev ntsuas hauv qab no muab cov lus qhia dav dav rau cov ntaub ntawv rwb thaiv tsev airgel siv nyob rau hauv aerospace ib puag ncig. Tus nqi tiag tiag tuaj yeem sib txawv nyob ntawm cov khoom teeb tsa thiab kev thov.

Nta thiab qhov zoo

Kev ua haujlwm zoo thermal rwb thaiv tsev: tsis tshua muaj thermal conductivity, xws li thermal conductivity ntawm silica airgel tsawg li 0.015W / (m・K). Cov qauv nanoporous muaj txiaj ntsig zoo cuam tshuam cov hluav taws xob hluav taws xob, txuas mus rau txoj kev hloov hluav taws xob, cais cov roj molecules, thiab inhibits convective tshav kub hloov.
Lightweight: extremely low density, low-density aerogel density as low as 15mg/cm³, the weight of the same volume is only 1/500 of steel, 1/180 of aluminum, and 1/60 of water, which is conducive to reducing the weight of aerospace vehicles and improving performance efficiency.

Q: Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm airgel hauv thaj chaw aerospace?
A: With ultra-low thermal conductivity (such as 0.015W/(m・K)), extremely light density (as low as 15mg/cm³) and high chemical stability, it can effectively insulate and reduce weight, resist the harsh environment of space, and improve the performance of spacecraft.

Q: Yuav ua li cas kom ntseeg tau tias kev ruaj ntseg ntawm cov khoom ua tau zoo?
A: Nrog rau cov txheej txheem tsim khoom thiab kev tswj xyuas nruj, cov khoom siv raw tau raug tshuaj xyuas rau ntau lub voj voog, thiab cov khoom raug saib xyuas thoob plaws hauv cov txheej txheem. Cov khoom lag luam dhau aerospace- qib siab kub tsis kam, hluav taws xob tiv thaiv thiab lwm yam kev ntsuas kom ntseeg tau ntev - lub sijhawm ruaj khov thiab kev ntseeg tau.

Q: Nws puas tuaj yeem hloov kho raws li qhov xav tau ntawm cov haujlwm sib txawv ntawm aerospace?
A: Customized ntau lawm tuaj yeem siv los kho cov airgel ntom ntom, porosity, cov duab thiab lwm yam tsis raws li qhov chaw thiab kev ua haujlwm ntawm lub dav hlau, thiab muab ntau yam khoom xws li daim hlau, cov ntaub ntawv, thiab cov txheej txheem.

Q: Tus nqi piv rau cov khoom siv li cas?
A: Txawm hais tias tus nqi pib yog siab, airgel tuaj yeem txo qhov tuab ntawm cov txheej txheem rwb thaiv tsev, txo qhov hnyav ntawm lub dav hlau, thiab txo qhov kev tso tawm thiab kev ua haujlwm thiab kev saib xyuas. Cov txiaj ntsig kev lag luam ntawm tag nrho lub voj voog yog qhov tseem ceeb, thiab cov khoom loj tuaj yeem txaus siab rau kev txo nqi.
