Cov flyers nquag yuav paub txog qhov tseeb tias lub dav hlau tshuab qee zaum mounted ntawm tis thiab qee zaum ntawm lub fuselage. Puas yog qhov kev npaj no arbitrary?
Qhov tseeb, cov tshuab dav hlau sib txawv tsis yog hauv kev ua haujlwm nkaus xwb tab sis kuj nyob rau hauv lawv qhov tshwj xeeb mounting qhov chaw. Feem ntau, lub dav hlau dav hlau cav, dhau li ntawm cov dav hlau sib xws-mounted configuration, kuj muaj tis- cag, tail-mounted, thiab tis-tail-mounted configurations.
Wing{0}}mounted Configuration
Cia peb pib nrog qhov feem ntau tis -mounted configuration. Qhov kev teeb tsa no tau tshwm sim thawj zaug ntawm cov neeg tawg rog thiab tom qab ntawd tau txais los ntawm Boeing 707, uas tau pab Boeing tsim nws txoj kev lag luam dominance. Thaum tau txais, qhov kev teeb tsa no tau dhau los ua qhov tseem ceeb. Nws cov koob meej tshwm sim los ntawm nws qhov zoo heev. Ua ntej, qhov kev teeb tsa no siv tau zoo siv lub cav qhov hnyav los cuam tshuam qee qhov ntawm lub zog ntawm lub tis -fuselage junction, ua si lub luag haujlwm tseem ceeb "tshem tawm".
Thaum lub sij hawm ya davhlau, lub dav hlau ua rau nce nce los ntawm tis, thaum lub fuselage hnyav ua rau lub ntiajteb txawj nqus tseem ceeb. Qhov no tsim ib qho tseem ceeb torque ntawm lub tis - fuselage junction, qhov twg lub nqa los ntawm lub tis thiab qhov ceeb thawj ntawm lub fuselage ua ke los tsim ib tug loj torque, ua rau lub tis cag qhov hnyav tshaj qhov taw tes ntawm lub dav hlau. Kev ncua lub cav hnyav heev hauv qab tis faib qee qhov hnyav thoob plaws tis, pab kom sib npaug ntawm lub zog ntawm lub hauv paus tis.
Kev ncua cov cav hauv qab tis kuj txo cov suab nrov tsis xis nyob. Cov tshuab dav hlau nrov nrov thaum lub sijhawm ya davhlau, tsim kom muaj kev cuam tshuam rau cov neeg caij tsheb ze ntawm lub cav. Ib puag ncig nyob ntsiag to yog ib qho qauv tseem ceeb rau kev nplij siab hauv dav hlau. Yog li ntawd, cov neeg tsim qauv dav hlau xav pom tias kev ncua cov cav hauv qab tis yuav tsis tsuas yog tso cai rau cov tis ua lub suab nrov tab sis kuj ua kom lub cav kom deb ntawm lub fuselage li sai tau, yog li txo cov suab nrov.
Tsis tas li ntawd, tshem tawm cov cav hauv qab tis muaj qhov zoo hauv qab no: lub cav yog ze rau hauv av, ua kom muaj kev saib xyuas thiab kho yooj yim dua; cov cav mounted hauv qab tis yog ze rau lub dav hlau qhov chaw ntawm lub ntiajteb txawj nqus, ua rau lub dav hlau tswj tau yooj yim dua; thiab vim yog thaj tsam loj ntawm tis, nws yog ib qho yooj yim los ntxiv lossis tshem tawm cov cav hauv qab tis. Mounting lub cav hauv qab tis tsis yog ib qho yooj yim; nws yuav tsum tau ua tib zoo xav txog yam xws li luag thiab airflow thaum ya davhlau. Kev lag luam dav hlau feem ntau yog qis -tis monoplanes. Nyob rau hauv cov ntaub ntawv no, aircraft designers yuav tsum xyuas kom meej tias lub engine mounted nyob rau hauv lub tis tsis dhau ze rau hauv av los tiv thaiv cov khoom ntawm cov av thiab puas.
Thaum peb feem ntau xa mus rau tis - mounted engines, lawv feem ntau mounted nyob rau hauv lub tis. Txawm li cas los xij, kuj tseem muaj cov xwm txheej uas qhov thim rov qab yog qhov tseeb, nrog lub cav tso rau saum lub tis. Qhov tseeb, los ntawm qhov kev xav ntawm overwing cav tsis raug txwv los ntawm av clearance thiab muaj tib lub unloading muaj nuj nqi raws li underwing engines, lub overwing engine layout yog scientific heev. Txawm li cas los xij, thaum lub cav tso rau saum lub tis, lub tis lub suab nrov tiv thaiv cov nyhuv yog ploj. Tsis tas li ntawd, txoj hauj lwm siab ntawm lub cav nyob rau hauv cov txheej txheem overwing ua rau kev saib xyuas nyuaj dua. Xav txog tag nrho cov xwm txheej no, lub dav hlau tam sim no siv lub cav overwing layout tsis ntau heev. [Kev tshaj tawm: Super ntxiv thiab kev ntxhov siab-relieving mini-game, nyem rau ua si!

Wing Root Layout
Lub tis cag layout yog keeb kwm tseem ceeb cav layout. Los ntawm cov dav hlau dav hlau thaum ntxov xws li Comet thiab Tu-104, cov neeg tsim qauv tau teeb tsa lub cav ntawm cov hauv paus hniav. Qhov kev teeb tsa no tau raug xaiv vim nws tso cai rau lub dav hlau tswj nws cov duab, tsim los ntawm peb lub ntsiab aerodynamic Cheebtsam: tis, fuselage, thiab tus Tsov tus tw, txo qis. Tsis tas li ntawd, vim hais tias cov cav nyob ze rau lub fuselage centerline thiab nruab nrab ntawm lub ntiajteb txawj nqus, qhov thrust imbalance nyob rau hauv cov kev tshwm sim ntawm ib tug unilateral engine tsis ua hauj lwm yog me me, simplifying lub davhlau tswj. Yog li ntawd, cov dav hlau dav hlau thaum ntxov feem ntau tau txais qhov kev teeb tsa lub cav no.
Txawm li cas los xij, qhov kev teeb tsa no tseem muaj cov kev txwv tseem ceeb. Lub tis - lub hauv paus cav layout tso lub cav ze rau ntawm lub fuselage, ua rau muaj suab nrov nyob rau hauv cabins thiab lub peev xwm rau cov cua kub tso pa taws ua rau lub fuselage puas. Tsis tas li ntawd, qhov kev teeb tsa no xav kom lub tis dhau los ntawm lub cav nacelle thiab txuas mus rau lub fuselage, ua rau muaj kev nyuaj siab rau kev tsim qauv thiab ua kom lub cev hnyav ntawm cov hauv paus hniav. Ntxiv mus, mounting lub cav nyob rau hauv lub tis qauv tsub kom qhov nyuaj ntawm lub cav tu. MBTI Test Entry (2025 official Website New Version) Qianyingzhi Cwm pwm Test View
Tail -mounted Layout
Tus Tsov tus tw - mounted layout tso cov cav nyob tom qab ntawm lub dav hlau. Thawj lub dav hlau dav hlau los txais yuav qhov kev teeb tsa lub cav no yog "Crossfire," thiab Boeing 727 tom qab ua raws.
Qhov zoo ntawm qhov kev teeb tsa no yog qhov pom tseeb: Ua ntej, tsis muaj qhov ntxiv protrusions hauv qab tis, txo qhov cuam tshuam ntawm lub cav nacelles ntawm nqa thiab luag; Thib ob, tsis muaj qhov yuav tsum tau nruj me ntsis rau qhov chaw underwing, tso cai rau cov neeg tsim qauv kom txo qis qhov tsaws iav qhov siab thiab txuag qhov hnyav ntawm cov qauv; thib peb, nws muab qhov chaw nyob ntsiag to thiab xis dua rau thawj -chav kawm, kev lag luam- chav kawm, thiab txawm tias cov chav kawm kev lag luam zoo nyob rau pem hauv ntej ntawm lub fuselage; thib plaub, lub cav txoj kab uas hla tsis txwv los ntawm qhov chaw, tso cai rau cov cav uas muaj qhov sib piv ntau dhau los; thib tsib, vim hais tias cov cav nyob ze ua ke, qhov cuam tshuam ntawm ib lub cav tsis ua hauj lwm ntawm lub dav hlau yaw yog tsawg dua nrog ib qho underwing - mounted layout. Qhov kev teeb tsa no kuj muaj qhov tsis zoo, xws li ua rau lub cav tsis muaj peev xwm thauj khoom -cov kabmob muaj peev xwm ntawm tis; Yuav tsum tau muaj lub siab -mounted kab rov tav stabilizer rau tus Tsov tus tw-mounted xyaw, yuav tsum tau ntxiv dag zog rau cov qauv ntsug thaum lub dav hlau tsim; thiab txwv tus naj npawb ntawm cov cav.
