Ngethuba lethu, abaninzi banengxaki yokuhamba ngomoya - ulwaphulo-moya . Abanye abantu bayabangela ukuphazamiseka kwesoyiki, ukucima nokuhlahlela, abanye bayesaba ukuba ii-injini ziza kuphazamiseka ngokukhawuleza, ngelixa abanye bekwesaba ukuhlaselwa kwamaphekula. Kwaye esinye sezizathu zokubangela ukuba abanye abantu basabe ukweba. Imele ingqongqo eqinile ngexesha lokuhamba. Oku kunokukuthusa, ngakumbi xa uhamba ngelokuqala. Abagibeli banokuvakalelwa kukuba kukho iingxaki kwiindlela zendiza, kwaye abaqhubi abaqhubekiyo bajamelana nokulawula. Kodwa enyanisweni, ingxubevange yinto eqhelekileyo, yendalo yendalo. Ukuze unqobe ukwesaba kwakho, kwanele ukuba ukwazi ukuba kutheni ukuphazamiseka kwinqwelo, kwaye kuyingozi kangakanani.
Iimbangela zokungcungcutheka
Ingqungquthela yongxakatho yafunyanwa ngo-1883 yinjineli uReynolds, isiNgesi. Wabonisa ukuba ngokunyuka kwinqanaba lokugeleza kwamanzi okanye umoya kummandla owenziwe, amaza atshabalalayo kunye ne-vortices zenziwe. Ngaloo ndlela, umoya uyingundoqo "yecala" loxinzelelo. Kwiindawo ezahlukileyo zeemeko, iamolekyuli zayo zinenani elithile kunye nobukhulu. Ukongeza, utshintsho lokushisa kunye noxinzelelo lwangaphakathi, kunye nesantya somoya (umoya). Ukudlula kwiindawo ezixhamla kwizantya eziphakamileyo, inqwelo "iyawela" kwimibhobho yomoya, umzimba wayo ugubha ngokugqithiseleyo, kwaye kwi-salon kukho okubizwa ngokuba yi "blubber". Ngokuqhelekileyo, indawo ezinjalo zomoya zokungazinzi zifumaneka kwindawo yomoya ngaphezu kweentaba kunye nolwandle, kunye nakwiindawo zezilwandle kunye namazwekazi. Iindawo eziqineleyo zengxubevange zingaphezu kolunxweme lwe-Ocean Ocean. Kwakhona, ngokuqinisekileyo uya kuziva ukuba yiyiphi intlanzi, ukuba inqwelo-moya iyifuma.
Ngaba ingxakeko iyingozi kwindiza?
Ngokwezibalo, iinqwelo-moya ziyaxhaswa kwi-85-90% yeenqwelo. Ngelo xesha, "i-bolt" ayikho inqabiseko yokhuseleko. Iimpawu zakhiwo zokwakhiwa kweenqwelo-moya zanamhlanje zinjalo ukuba umzimba we "intaka yentsimbi" yenziwe ngokubhekisele kwiingxaki ezinamandla. Ukongezelela, uyilo lunikeza iimbophu ezikhethekileyo, ezandisa ukwanda koxinzelelo lwangaphakathi. Izixhobo ezitsha ezifakwe ebhodini zibanceda abaqhubi bee-pilot ukuba babone ngaphambili kwendawo yokuqhubisana okunokwenzeka kwaye bayiphephe, baphambuke kancane kwikhosi.
Into eyona nto iyingozi kakhulu eyongela umgibeli ngexesha lokuhamba kwendiza ngendawo yongxubevange yengozi yokulimala ukuba, xa edibanisa, uyashiya esihlalweni sakhe, akayi kuguqa okanye awele emithinini embi ephezulu. Ngaphandle koko, akukho sizathu sokwesaba. Iinyani zizithetha zona ngokwazo: ukusuka kwintlanzi ekuhambeni kwendiza, ayikho enye indiza ephazamisekile kwiminyaka eyi-25 edluleyo.
Ingqungquthela ibonakala ngathi iyingozi xa ulo mzuzwana kwikhawuni yendiza endaweni yomgibeli. Ukuba si the lekisa
