Ib nqe lus siv los piav txog kev sib raug zoo ntawm kev downforce ib lub tsheb tsim, thiab luag. Txoj kab ncaj nraim nyob ntawm aero efficiency. Feem ntau, nrog ntau downforce generated los ntawm tis, ntau drag yog generated.
Aerodynamic efficiency txhais li cas ?
Ib qho kev ntsuas uas ntsuas tus qauv tsim kom muaj zog aerodynamic rau lub davhlau tsis tau zoo. Qhov kev ntsuas feem ntau ntawm aerodynamic efficiency yog nqa / rub piv. Saib kuj nqa/dag piv.
Aerodynamic efficiency hauv cua turbine yog dab tsi?
Feem ntau ntawm cov cua turbines muaj ob lossis peb lub tshuab turbine. Lub aerodynamic efficiency nce nrog tus lej ntawm cov hniav. Lub aerodynamic efficiency nce nrog tus naj npawb ntawm cov hniav. Tab sis txo tus naj npawb ntawm cov hniav ntau dua tus nqi ntawm qhov nrawm.
Aerodynamic efficiency mis yog dab tsi?
Hauv aerodynamics, qhov nqa-rau-drag piv (lossis L / D piv) yog tus nqi nqa los ntawm tis lossis tsheb, faib los ntawm aerodynamic luag nws tsim los ntawm kev txav mus los ntawm huab cua… Lub sij hawm yog xam rau ib qho tshwj xeeb airspeed los ntawm kev ntsuas lub lift generated, ces faib los ntawm tus cab ntawm qhov ceev.
airfoil efficiency yog dab tsi?
Yog tias lub dav hlau tsim los rau kev ya davhlau qis, lub dav hlau tuab yog qhov ua tau zoo tshaj plaws, hos lub dav hlau nyias muaj peev xwm ua tau zoo dua rau kev ya davhlau siab. Feem ntau muaj ob hom airfoils: laminar ntws thiab pa. Laminar flow airfoils yog thawj zaug tsim los ua kom lub dav hlau ya nrawm dua.

Dab tsi yog bayeux tapestry dab tsi yog qhov cuam tshuam ntawm qhov kev tshwm sim nws ua kev nco txog?
Kristine Tanton. Ntsuas nees nkaum ntiv tes siab thiab yuav luag 230 ko taw ntev, Bayeux Tapestry ua kev nco txog kev tawm tsam rau lub zwm txwv ntawm Askiv ntawm William, Duke of Normandy, thiab Harold, Earl ntawm Wessex(Normandy yog ib cheeb tsam nyob rau sab qaum teb Fabkis).
Puas muaj lo lus zoo li aerodynamically?
aer•o•dy•nam•ic /ˌɛroʊdaɪˈnæmɪk/ adj. [ua ntej lub npe] ntawm lossis cuam tshuam nrog kev kawm txog kev txav ntawm air thiab lwm yam roj: aerodynamic cov ntsiab lus. muaj peev xwm ntws tau yooj yim thiab yooj yim los ntawm huab cua:
Dab tsi yog qhov kev xaiv dab tsi yog jared goff?
Tus Rams kuj tau txais ob qhov kev xaiv 2016. Los Angeles xaiv Jared Goff, qhov kev cia siab saum toj kawg nkaus hauv lub quarterback, ntawm No. 1 tag nrho . Rams pauv dab tsi los sau Goff? Los Angeles Rams tab tom ua lag luam ob qhov kev xaiv thawj zaug, ib qho kev xaiv thib peb, thiab Jared Goff rau Detroit Lions pauv rau quarterback Matthew Stafford, raws li ESPN's Adam Schefter.

Scout piav qhia tias Maycomb nyob nees nkaum mais hauv av los ntawm Finch's Landing vim Sinkfield, tus tswv tsev noj mov uas muag cov mos txwv rau cov neeg Khab thiab cov neeg nyob, cov neeg soj ntsuam tsis txaus ntseeg los tsim Maycomb lub rooj zaum ntawm tsoomfwv ncig nws tavern .
Aerodynamically npaum txhais li cas?
Ib nqe lus siv los piav txog kev sib raug zoo ntawm kev downforce ib lub tsheb tsim, thiab luag. Nws yog tsis yooj yim sua los tsim downforce yam tsis tau tsim cov cab, tab sis txoj hauj lwm ntawm aerodynamicists yog tsim kom muaj zog downforce, rau me ntsis luag, li sai tau.
