Txhua yam hais txog lub dav hlau log tsheb

Nws yog lub log tsheb uas ua rau txhua yam kev ua haujlwm thev naus laus zis (tshwj tsis yog rau ib qho: sab tuav)

20 bar siab, 340 km / h, kub sib txawv ntawm -50 txog 200 ° C, tshaj 25 tons ntawm load ...

Tom qab pom yuav ua li cas lub log tsheb GP yog qhov kawg ntawm lub log tsheb maus taus, ntawm no yog qhov kev nkag siab ntxiv rau hauv lub ntiaj teb zoo kawg ntawm cov log tsheb! Thiab qhov illumination coj peb dav hlau loguas yog lub tsheb npav tiag tiag uas tsom rau cov teeb meem thev naus laus zis tshaj plaws. Tab sis cia peb muab qee cov ntsiab lus ntawm cov ntsiab lus ua ntej mus rau lub plawv ntawm qhov teeb meem.

4 tsev neeg loj thiab thev naus laus zis paradox

Lub ntiaj teb ntawm aviation tau muab faib ua plaub tsev neeg tseem ceeb: Civil aviation hais txog cov dav hlau me me xws li Cessna. Lub cheeb tsam aviation txhawj xeeb txog cov dav hlau nruab nrab uas muaj peev xwm ntawm 20 txog 149 lub rooj zaum, uas mus txog ntau pua mais, nrog rau cov dav hlau ua lag luam. Kev lag luam aviation muaj peev xwm ua haujlwm hla kev ya davhlau. Raws li rau tub rog aviation, nws yog aptly npe.

Txawm li cas los xij, lub log tsheb dav hlau raug kev txom nyem los ntawm qhov tsis zoo. Nws tau lees tias yog hyper-tech, tab sis nyob rau hauv peb ntawm plaub lub lag luam tsev neeg (civil, regional thiab tub rog aviation), aviation roj hmab tseem feem ntau diagonally tech-savvy. Yog, kab pheeb ces kaum, tsis radial zoo li peb zoo qub pem hauv ntej txuas los yog, tsis ntev los no, qhov zoo Honda CB 750 K0! Qhov no yog vim li cas nyob rau hauv pej xeem aviation, piv txwv li, muaj ntau lub npe uas muaj peev xwm muab log tsheb.

Yog vim li cas yog yooj yim: nyob rau hauv aviation, tivthaiv cov qauv kev pom zoo yog heev nruj thiab complex. Yog li, thaum ib feem tau pom zoo rau ntawm lub dav hlau, nws yog validated rau lub neej ntawm lub aircraft. Homoloding lwm qhov yuav kim heev, thiab txij li lub neej ntawm lub dav hlau yog tsawg kawg 3 xyoo caum, qee zaum ntev dua, cov kauj ruam thev naus laus zis qeeb dua li lwm qhov chaw. Yog li, txhua tiam tshiab ntawm lub dav hlau accelerates tus nqi ntawm kev lag luam radialization.

Qhov no yog qhov nyuaj dua hauv kev lag luam aviation, qhov twg cov qauv tseem nruj dua. Yog li ntawd, cov log tsheb yog radial, thiab tsuas yog ob tus neeg ua haujlwm paub txog cov thev naus laus zis no thiab sib koom ua lag luam: Michelin thiab Bridgestone.

Lub neej (nyuaj) ntawm Boeing lossis Airbus lub log tsheb

Xav txog tias koj yog lub dav hlau tsheb npav (tsis muaj laj thawj, Hindus npau suav ntawm kev rov ua dua tshiab li nyuj lossis paj paj). Yog li, koj yog lub dav hlau log tsheb haum rau, hais, Airbus A340 lossis Boeing 777, hauv lawv qhov ntev-ntev version. Koj nyob ntsiag to ntawm tarmac ntawm Terminal 2F hauv Roissy. Txoj kev hauv tsev tau raug tshem tawm. tsw tsw tshiab. Cov neeg coob tuaj. Hm, cov hostesses zoo hnub no! Cov bins qhib, lub nra tuaj, cov neeg caij tsheb tawm, lawv zoo siab mus so. Cov tais zaub mov loaded: nyuj los yog qaib?

Ntawm qhov tod tes, koj xav tias hnyav me ntsis, zoo li yog nyem rau hauv koj lub xub pwg nyom. Kuv yuav tsum hais tias yuav luag 200 litres ntawm kerosene twb nyuam qhuav muab pov rau hauv koj tis. Tag nrho suav nrog, lub dav hlau tuaj yeem hnyav ze li 000 tons. Obviously, koj tsis yog ib leeg nqa tag nrho cov loj no: lub Airbus A380 muaj 340 log tsheb, lub A14, 380. Txawm li cas los, txawm hais tias koj qhov ntev yog piv rau qhov ntev ntawm lub tsheb log tsheb, koj yuav tsum nqa ib tug load ntawm 22 tons, thaum lub sij hawm ib tug. tsheb log tsheb tsuas yog nqa qhov nruab nrab ntawm 27 tons.

Txhua tus tau npaj pib. Kev ua kom swb. Tshawb xyuas lub qhov rooj rov qab. Nws yuav ua mob rau koj nyob ntawd. Vim tias kom tawm ntawm qhov tsaws, lub dav hlau hnyav hnyav yuav tig ntawm nws tus kheej kom tawm ntawm nws qhov chaw nres tsheb. Cov roj hmab rau lub log tsheb yuav ua rau muaj kev cuam tshuam, ib hom kua muag ntawm qhov chaw sib cuag. Aws!

Lub sijhawm hu ua "taxi": tsheb tavxij nruab nrab ntawm lub rooj vag thiab txoj kev khiav. Qhov kev mus ncig no tau ua tiav ntawm qhov txo qis, tab sis raws li lub tshav dav hlau loj dua, nws tuaj yeem ua tau ntau tshaj li ob peb kilometers. Ntawm no, qhov no kuj tsis yog xov xwm zoo rau koj: lub log tsheb hnyav hnyav, nws yob rau lub sijhawm ntev thiab ua kom sov. Nws yog qhov phem dua ntawm lub tshav dav hlau loj nrog qhov kub siab (xws li Johannesburg); zoo dua nyob rau hauv lub tshav dav hlau me me nyob rau sab qaum teb lub teb chaws (xws li Ivalo).

Nyob rau hauv pem hauv ntej ntawm tus khiav: gas! Hauv txog 45 vib nas this, tus tsav yuav ncav cuag nws qhov nrawm nrawm (250 txog 320 km / h nyob ntawm lub zog ntawm lub dav hlau thiab cua). Qhov no yog qhov kawg-ditch kev rau siab rau lub log tsheb aviation: kev txwv ceev tau ntxiv rau qhov thauj khoom thiab tom qab ntawd lub log tsheb tuaj yeem ua kom luv luv txog li 250 ° C. Ib zaug nyob rau hauv huab cua, lub log tsheb nkag mus rau hauv kab noj hniav rau ob peb teev. pw tsaug zog, tu siab? Qhov ntawd yog dab tsi, tshwj tsis yog nws yog -50 ° C! Nyob rau hauv cov xwm txheej no, ntau cov ntaub ntawv yuav nyuaj li ntoo thiab nkig li iav: tsis yog lub log tsheb, uas yuav tsum tau kho sai sai rau tag nrho nws cov zoo.

Tsis tas li ntawd, txoj kev khiav yog pom. Tawm ntawm lub tsheb ciav hlau. Lub dav hlau kov hauv av smoothly ntawm qhov ceev ntawm 240 km / h. Rau lub log tsheb, qhov no yog kev zoo siab, vim hais tias yuav luag tsis muaj kerosene, yog li txhua yam hnyav ib puas tons tsawg dua, thiab yog li ntawd thaum lub sij hawm siv zog no tsuas yog nce mus rau qhov kub ntawm 120 ° C! Ntawm qhov tod tes, carbon discs cua sov me ntsis, 8 lem ntawm uas tsim tau ntau tshaj 1200 ° C ntawm tshav kub. Kub kub! Ob peb mais luv luv ntawm tsheb tavxij thiab lub dav hlau tsheb npav yuav tuaj yeem txias thiab so ntawm asphalt, tos lub voj voog tshiab ... tau teem sijhawm hauv ob peb teev!

NZG los yog RRR, advanced technology

Lub Xya Hli 25, 2000: Kev xwm txheej ntawm Roissy thaum Concorde ntawm Air France Davhlau 4590 rau New York poob 90 vib nas this tom qab tawm. Ib qho ntawm cov log tsheb raug puas tsuaj los ntawm cov khib nyiab pov tseg ntawm txoj kev khiav; ib daim log tsheb tawm, kov ib lub tso tsheb hlau luam thiab ua rau tawg.

Nyob rau hauv lub ntiaj teb no ntawm aeronautics, qhov no yog txaus ntshai. Cov neeg tsim khoom yuav raug siv los tsim cov log tsheb muaj zog. Ob tus neeg ua lag luam loj hauv kev ua lag luam yuav ntsib qhov kev sib tw: Michelin nrog NZG (Zoo Zero Kev Loj Hlob) thev naus laus zis, uas txwv cov log tsheb deflation (piv txwv li, nws muaj peev xwm deform nyob rau hauv siab, uas ua rau nws tsis kam), nrog aramid reinforcements nyob rau hauv lub log tsheb carcass, thiab Bridgestone nrog RRR (Revolutionary Reinforced Radial) uas ua tiav Nws yog NZG thev naus laus zis uas tso cai rau Concorde rov qab mus rau huab cua ua ntej so haujlwm.

Muab ob npaug rau kev hnia txias: lub log khov kho deforms tsawg dua, yog li txo cov dav hlau siv roj thaum lub caij tsheb tavxij.

Cov qauv kev lag luam tshwj xeeb

Hauv ntiaj teb kev lag luam, koj tsis txhawj xeeb ntau dhau ntawm kev yuav cov log tsheb. Vim yog koj yuav lawv, koj yuav tsum khaws, sau, kos, hloov, rov ua dua ... Nws nyuaj. Tsis yog, hauv ntiaj teb kev lag luam lawv raug xauj tawm. Yog li ntawd, cov tuam txhab tsim log tsheb tau nkag mus rau hauv kev sib raug zoo ntawm kev sib raug zoo: saib xyuas kev tswj hwm, muab khoom thiab kev saib xyuas ntawm lub dav hlau log tsheb thiab, ntawm qhov tod tes, them nqi rau cov dav hlau tsaws. Txhua tus neeg nyiam qhov no: cov tuam txhab tsis txhawj xeeb txog cov ntsiab lus thiab tuaj yeem kwv yees tus nqi, thiab ntawm qhov tod tes, cov tuam txhab tau txais txiaj ntsig los ntawm kev tsim cov log tsheb ntev dua.

Los ntawm txoj kev, lub log tsheb lag luam aviation kav ntev npaum li cas? Qhov no tsis tshua muaj tshwm sim: nws yog nyob ntawm qhov load ntawm lub dav hlau, qhov ntev ntawm lub caij tsheb tavxij, qhov kub thiab txias, thiab qhov xwm txheej ntawm txoj kev khiav. Cia peb hais, nyob ntawm cov kev txwv no, muaj ntau yam ntawm 150/200 txog 500/600 qhov chaw. Qhov no ua rau me me rau lub dav hlau uas tuaj yeem ua tau ib lossis ob lub davhlau ib hnub. Ntawm qhov tod tes, los ntawm tib lub cev nqaij daim tawv, cov log tsheb no tuaj yeem ua tau rov qab los ob peb zaug, tswj qhov kev ua tau zoo ib yam txhua zaus raws li lub log tsheb tshiab, vim tias lawv cov carcass yog tsim los rau qhov ntawd.

Ib rooj plaub tshwj xeeb ntawm fighters

Qhov hnyav dua, nrawm dua, tab sis kuj muaj qhov ntim tsawg dua (vim qhov chaw muaj kev txwv ntau dua ntawm kev sib ntaus sib tua, aviation log tsheb yog 15 ntiv tes) thiab, qhov tseem ceeb tshaj plaws, ib puag ncig txwv tsis pub tshaj, vim, piv txwv li, lub dav hlau ntawm Charles de Gaulle yog 260 meters, thiab lub dav hlau mus txog ntawm ib tug ceev ntawm 270 km / h! Yog li lub hwj chim ntawm lub zog retarding yog downright siab phem, thiab lub dav hlau tswj kom nres los ntawm dai cables (hu ua "xov" nyob rau hauv nruab nrab) tuav los ntawm ib tug twj tso kua mis nrog pressures txog li 800 bar.

Takeoff ceev yog 390 km / h. Txhua lub log tsheb tseem yuav tsum nqa 10,5 tons thiab lawv lub siab yog 27 bar! Thiab txawm hais tias cov kev txwv no thiab cov ntsiab lus nyuaj heev, txhua lub log tsheb hnyav tsuas yog 24 kilograms.

Yog li, ntawm cov dav hlau no, lub log tsheb lub neej luv dua thiab tej zaum yuav raug txwv los ntawm qhov haum yog tias lub log tsheb tsoo ib txoj hlua khi thaum tsaws. Hauv qhov no, nws yog hloov los ntawm kev ntsuas kev ruaj ntseg.

xaus

Yog li: lub log tsheb dav hlau muaj tag nrho cov ntim ntawm lub tsheb log tsheb. Tab sis lub log tsheb thauj mus los ntawm qhov ceev ntawm 100 km / h, inflates mus rau 8 bar, nqa txog 5 tons thiab hnyav txog 60 kilograms. Cov log tsheb dav hlau taug kev ntawm 340 km / h, nqa 20 mus rau 30 tons thiab, raws li lawv tau txhawb nqa thoob plaws qhov chaw, hnyav 120 kilograms thiab inflated mus rau 20 bar. Tag nrho cov no siv technology, txoj cai?

Peb tab tom twv tias tom qab nyeem tsab xov xwm no, koj yuav tsis caij lub dav hlau yam tsis tau saib nws lub log tsheb nrog lwm lub qhov muag?
