Ib lub tsheb kauj vab aero uas zuam lub thawv rau nws qhov nrawm thiab nrawm, tab sis qhov hnyav tag nrho tuav nws lub sijhawm
Kuv muaj qhov muag muag rau cov tuam txhab tsheb kauj vab uas muaj npe tom qab lawv tus tswv. Muaj ib zaug nws yog vim muaj ib tug laus laus uas tsw tsw zoo li cov tin kub thiab haus luam yeeb ua rau cov thwj tim, yog li ntawd ib txwm daig nws lub npe rau ntawm lub raj.
Nws yog vim li cas thiaj muaj cov tsheb kauj vab zoo li Hilton Wrigley, Whitaker & Mapplebeck, Leach Marathon thiab Pemberton Arrow (OK, yog li 'Xub' thiab 'Marathon' yog cov qauv npe, tab sis tseem, lawv yuav ua tau zoo heev Agatha Christie cov cim). Nws kuj yog vim li cas Felt yog Felt, muaj npe tom qab tus tsim Jim Felt, uas tau pib ua haujlwm hauv xyoo 1991.
Jim txij li tau ncaim mus, tau raug yuav los ntawm kev sib tw kis las Groupe Rossignol hauv 2017, tab sis lub tuam txhab kev tsav tsheb rau kev tsim kho tshiab tseem muaj zog.
Xav tias tus txiv neej tau sim ua kom zoo meej aero-triathlon tsheb kauj vab kom deb li deb rov qab mus rau xyoo 1980; Xav tias lub tuam txhab nyuam qhuav unleashed no redesign ntawm nws AR. Aerodynamics, ces, tseem yog pem hauv ntej thiab nruab nrab ntawm Felt masterplan.
Angularity clarity
Yog tias koj tsis ntseeg Felt cov ntawv pov thawj rau aerodynamics, xav tias Felt IA triathlon tsheb tuam tau yeej rau qhov ncaj ncees Ironman World Championships.
Felt kuj cua-tunnel kev sim ntawm San Diego Low Speed Wind Tunnel (uas yog me ntsis zoo li mus rau Lindt lub Hoobkas kom cuam tshuam nrog truffles), tau txhawb nqa ntau pab pawg pro, thiab hauv AR muaj nyob ze -on tsib xyoos R&D.
Lub xeem AR tau tuaj txog xyoo 2014, thiab raws li tus thawj coj ntawm kev txhim kho Alex Soria hais tias, 'Peb tau txheeb xyuas qhov project no txog ib xyoos tom qab ntawd, tau tos rau disc nres kom kos npe rau yav tom ntej. Kev ua lub tsheb kauj vab tshiab tsuas yog qhov peb tsis xav ua, yog li nws yuav tsum tau nrawm dua.'
Qhov tshwm sim yog qhov tsis txaus ntseeg ntawm cov lej rub uas ua pov thawj qhov no yog Felt txoj kev tsheb kauj vab nrawm tshaj plaws rau hnub tim, nrog kev thov kev txhim kho kev ua tau zoo hauv qab 10 ° yaw (cov xwm txheej uas Felt hais tias cov neeg caij tsheb siv sijhawm li 90% ntawm lawv lub sijhawm), xws li 0.7% ntawm 10 ° nres lub kaum sab xis ntawm cua, mus rau 9.4% ntawm 0 ° yaw.

Yaw cov ces kaum los yog yawn ces kaum, Kuv tsis xav tias leej twg yuav ua tsis tau raws li qhov yuav tsum tau ceev npaum li cas qhov no accelerates. Tsis yog txij li Venge ViAS, uas kuv tau sim rov qab rau xyoo 2016, kuv puas tau zoo siab heev los ntawm lub tsheb kauj vab nrawm ntawm lub cim. Tab sis tsuas yog saib ntawm AR, nws ua rau kev nkag siab.
Sab-ntawm lub tsheb kauj vab yog tsawg lub rooj vag ya thiab ntau lub qhov rooj ya. Ntsuas 58mm sib sib zog nqus, Reynolds 'AR log yog ob peb ntawm 12-nti vinyls deb ntawm kev ua discs, thiab cov duab raj, txawm hais tias truncated teardrop-style, siab.
Meanwhile, lub log tsheb tom qab lub tog raj ntawm lub scalloped trailing ntug (hais lus nicknamed 'ntses di ncauj' rau nws flared npoo); lub diav rawg ob txhais ceg yog dav, lub tessellating crown seem ntau heev; lub qia tuaj yeem tuav kua txob hauv lub tsev noj mov Italian, thiab koj tuaj yeem tuav rab ntaj hauv lub rooj zaum ntawd. Tab sis saib AR square-on thiab lub tsheb kauj vab ze ploj mus.
Hauv qhov no, AR xav tias yuav luag hnub. Siab thiab nqaim aero-bikes zoo li cov xov xwm qub. Tab sis tom qab ntawd dua, saib lub ntiaj teb uas tsis yog UCI tswj hwm triathlon, qhov twg lub tsheb kauj vab aerodynamics yuav luag txhua qhov tseem ceeb, thiab qhov siab-qis kav zoo tshaj plaws.
Yog li tsis hais txog qhov zoo nkauj, tsis muaj qhov tsis lees paub lub tsheb kauj vab no nrawm nrawm - ob qho tib si tawm ntawm lub cim thiab thaum sprinting - thiab txiav zoo heev los ntawm lub taub hau. Nws txawm cuam tshuam nrog gusty sab-ntawm cua nyob rau hauv ib txoj kev nws loj deg cheeb tsam belies. Yog li txoj haujlwm tiav rau Felt?
Aero vs nyhav
Ua ntej thiab qhov tseem ceeb tshaj plaws, Kuv tsis tuaj yeem xav tias leej twg poob siab rau lub tsheb kauj vab no. Nws nrawm thiab lom zem caij, thiab yeej tig taub hau. Txawm li cas los xij, rau kuv muaj kev cuam tshuam uas kuv tsis kam ua.
Qhov kev nplij siab tag nrho yog qhov zoo heev, lub rooj zaum yog qhov zoo ntawm qhov khoob, txhais tau hais tias ob lub halves tuaj yeem hloov tau ntawm nws tus kheej, thiab nws txawm zaum hauv lub tes tsho roj hmab kom ntxiv dampen vibrations.
Tab sis lub clamping mechanism yog finicky los kho lossis ntim rau hauv kev mus ncig, thiab qee yam hauv kuv cov khoom yuav tsum tau txiav me me strips ntawm cov roj hmab ntshiab (muab) los ntxig rau hauv qhov sib txawv ntawm cov prongs. Nws zoo li ib txoj hauv kev los daws qhov teeb meem uas yuav tsum tsis muaj.
Txawm li cas los xij, txhua yam no kuv tuaj yeem zam txim tau nws tsis yog qhov hnyav. Kuv paub tias muaj ib qho kev sib cav uas hais tias aero nrawm dua qhov hnyav, tab sis raws li tus neeg caij tsheb tawm kom muaj kev lom zem hauv txhua qhov xwm txheej, qhov hnyav tseem ceeb vim kuv xav tias nws txhua zaus kuv txav lub tsheb kauj vab hauv qab kuv.
Ib lub tsheb kauj vab 8.5kg yog 12% hnyav dua li lub tsheb kauj vab 7.6kg, thiab 7.6kg yog qhov hnyav sab nraud ntawm qhov kuv tau ua rau lub tsheb kauj vab sab saum toj kawg nkaus. Hauv luv luv, qhov hnyav ntawd pom tau zoo heev.

Rau kuv, Kuv yuav siv lub dav hlau poob qis rau kev caij tsheb ntau dua, txawm hais tias kuv lees tias qhov no tsis yog qhov kev pom los ntawm txhua tus, thiab qhov no kuj yog qhov kev xav rau Felt, uas xav tau (ha!) kev sib haum xeeb yog tsim nyog. Ntxiv rau, muaj qhov ua kom zoo dua FRD ntau dua tuaj sai sai (zoo tib yam, sib txawv layup), yog li thaum tseem tsis tau luam tawm cov duab hnyav, nws yuav sib dua - tab sis kuj kim dua.
Txhua yam hais, AR yog lub tsheb kauj vab suav tias yog lwm qhov zoo ntxiv rau aero oeuvre. Uas yuav yog ib lub npe zoo rau lub qhov cua-tooj sim chocolate.
