"I-Aerodynamics? Lena eyalabo abangazi ukwakha izinjini" . Lena kube yimpendulo ka-Enzo Ferrari, umsunguli odumile wohlobo lwe-Italian, kumshayeli u-Paul Frère e-Le Mans - ngemva kokungabaza idizayini ye-windshield ye-Ferrari 250TR. Futhi ingeminye yemisho edume kakhulu emhlabeni wezimoto, futhi ikhombisa ngokusobala ukubaluleka okwanikezwa ukuthuthukiswa kwenjini phezu kwe-aerodynamics. Ngaleso sikhathi, isayensi ecishe ifihliwe embonini yezimoto.
Ngemuva kweminyaka engama-57, kuyinto engacabangeki ngomkhiqizo ukuthi uthuthukise imodeli entsha ngaphandle kokunaka i-aerodynamics - kungaba yi-SUV noma imodeli yokuncintisana. Futhi yilokhu lapho kokubili okonakalisayo kanye nophiko olungemuva (noma uma uthanda, i-aileron) kuthatha ukubaluleka okungaguquki ekulawuleni ukudonsa kwe-aerodynamic kanye/noma ukwehlisa amandla amamodeli, okuthonya ngokuqondile ukusebenza - ingasaphathwa ingxenye yobuhle.
Kodwa ngokuphambene nalokho abantu abaningi abangase bakucabange, lezi zithasiselo ezimbili ze-aerodynamic azinawo umsebenzi ofanayo futhi zihlose imiphumela ehlukene. Ake sikwenze ngezinyathelo.
umphangi
Ibekwe ngemuva kwemoto — phezulu efasiteleni elingemuva noma ebhuthini/isivalo senjini — inhloso enkulu ye-spoiler ukunciphisa ukudonsa kwe-aerodynamic. Ukudonsa kwe-aerodynamic kuqondwa njengokumelana nokuhamba komoya emotweni ehambayo, ungqimba lomoya ogxile kakhulu ngemuva - ovala isikhala esidalwa umoya odlula emotweni - futhi "ebuyisela" imoto emuva.
Bhalisela iphephandaba lethu
Ngokwenza uhlobo "lomcamelo" womoya ocishe umile ngemuva kwemoto, i-spoiler yenza umoya wesivinini esikhulu udlule kulo "mcamelo", wehlise isiyaluyalu nokudonsa.
Ngalo mqondo, i-spoiler yenza kube nokwenzeka ukuthuthukisa isivinini esiphezulu nokunciphisa umzamo wenjini (kanye nokusetshenziswa ...), ngokwenza imoto ingabi namandla ukuwela emoyeni kalula. Nakuba kungase kube nomthelela kancane ekunciphiseni amandla (usekelo olungeluhle), leyo akuyona injongo eyinhloko yokonakaliswa — ngalokho sinophiko olungemuva.
iphiko elingemuva
Ngakolunye uhlangothi kukhona iphiko elingemuva. Nakuba umgomo we-spoiler kuwukunciphisa ukudonsa kwe-aerodynamic, ukusebenza kwephiko elingemuva kuphambene ncamashi: ukusebenzisa ukugeleza komoya ukudala amandla abheke phansi emotweni: i-downforce.
Ukuma kwephiko elingemuva kanye nokuma kwalo okuphezulu kwenza umoya uvame ukudlula ngaphansi, eduze nomzimba, ukwandisa ukucindezela futhi ngaleyo ndlela usize "ukunamathisela" ingemuva lemoto phansi. Nakuba ingaphazamisa isivinini imoto ekwazi ukufinyelela kuso (ikakhulukazi uma ine-angle ehlaselayo), iphiko elingemuva livumela ukuqina okuthuthukisiwe emakhoneni.
Njenge-spoiler, iphiko elingemuva lingakhiwa ngezinto ezihlukahlukene - ipulasitiki, i-fiberglass, i-carbon fiber, njll.
Iphiko elingemuva liphinde libe nokunye ukusetshenziswa... Kulungile, ngaphezulu noma ngaphansi ?
