Isiteji sezindiza yisimo se-aerodynamic lapho indiza idlula khona i-angle yokuhlaselwa ebaluleke kakhulu futhi ayisakwazi ukukhiqiza ukuphakama okudingekayo ngendiza evamile. Lolu hlobo lwesitembu akufanele ludideke nesiteji senjini, ejwayele kunoma ubani oye waqhuba imoto. Lapho ushayela indiza, i-stall ayinalutho neze injini noma enye ingxenye yomshini. Ekuphenyweni, i-stall ichazwa nje ngokuthi ukulahleka kwe-eleversiyomu ye-aerodynamic eyenzeka lapho i-airfoil (okungukuthi, iphiko lendiza) lidlula i-angle yokuhlaselwa.
I-Angle of Attack
I-angle yokuhlaselwa e-airfoil ilinganiswa nge-angle phakathi komugqa wokulinganisa (okungukuthi, umugqa ongacabangi ovela emaphethelweni oholela ekugcineni komaphiko wephiko) nomoya ohambisanayo. Kuncike ekubunjweni kwe-airfoil, kufaka phakathi isiteji sayo nesilinganiso sesici. E-angle ephakeme yokuhlaselwa, ukugobhoza umoya phezu kwephiko kuphazanyiswa.
Esimweni esibucayi sokuhlaselwa, ukuqhuma umoya phezu kwephiko kuphazanyiswa ngokwanele ukuvimbela ukuphakamisa, okuholela ekuphumeni kwezindiza. I-angle ebalulekile yokuhlaselwa kwe-airfoil ayiguquko. Noma kunjalo, izici ezinjengeyisisindo, ukumiswa (isib. Ama-flaps nezinguquko zamagesi, noma ezinye izimo, njenge-icenferencing icing ), ne-factor factor, ingashintsha umoya ozoyibeka kuyo indiza.
Izitayela zesitayela
Izimpawu zesitayela zihlanganisa ukwehla okuhlukile kokuphakanyiswa, okuvame ukuphawula ngokungazelelwe (uma ngezinye izikhathi kufinyelela kancane) kwehla kwempumu yendiza.
Nakuba lokhu kungase kuzwe sengathi indiza iyawa futhi ayikho ukuphakama, empeleni, kuyancipha nje ekuphakameni nasekushintsheni izinga lendiza. Ukwengeza, i-stall ingase ihambisane nomqulu noma i-waw kuya ohlangothini olulodwa uma indiza ingabonakali kahle. Uma lokhu kwenzeka futhi izinqubo zokutakula aziqalanga ngaso leso sikhathi, indiza ingangena nge-spin.
Ukuzinza
Endizeni ezinzile, ukwehla emakhaleni ekuqaleni kwesiteji ngokuvamile kunokwanela ukuphinde uthole inani elifanele lokuphakanyiswa kwe-airfoil. Uma lokhu kwenzeka, indiza ilulameka kalula nje ngokunciphisa isimo sayo sengqondo futhi ikhuphuke emoyeni. Kodwa-ke, endizeni engazinzile, isiteji esingalungiswanga singathuthuka sibe yi-spin, okungaba nzima noma akunakwenzeka ukululama.
I-Airspeed
Izitayela zivame ukuvela ezindizeni zokuhamba kancane. Ngenxa yalesi sizathu, izindiza ezinjengejubane, njengesikhathi sokuhamba nokuhamba, ziyizigaba ezibalulekile zezindiza, futhi abashayeli bezindiza kumele baqaphele ikakhulukazi ngalezi zikhathi ukuvimbela ukudilika indiza. I-stall e- altitude ye- cruise inikeza umshayeli isikhala esanele ukuze alulame. Isiteji ngesikhathi sokufika ngendawo encane ayinikezi imvulophu efanayo yokuphepha okumele ilulame kuyo.
Nakuba ukugwinya kungase kuvame ukuhamba ngesivinini esisheshayo, i-stall ingenzeka kunoma iyiphi i-airspeed, kungakhathaliseki isimo sengqondo. Ngakho-ke, umshayeli we-pilot akufanele aqaphele ukuthi kungenzeka yini isiteji esisekelwe emoyeni noma isimo sengqondo. Isibonelo, uma udonsa phansi, i-airspeed iphakeme, kodwa i-angle yokuhlaselwa ingaba phezulu kunalokho ucabanga ngoba indiza isesehla endaweni ephakeme ngisho noma ikhala layo liphakanyisiwe.
Uma i-angle yokuhlasela idlula cishe amaphesenti angu-17, indiza ingaba khona.
Izitayela ze-Tailplane
Izitayela zezindiza zivame ukukhombisa ukuthi kukhona okwenzekayo kumaphiko ezindiza, kodwa isiteji esiyizingqimba sezindiza singagcina futhi. Ngenkathi le stall ye-tailplane ibuye ibe yingozi, kuyisimo esingajwayelekile kakhulu se-aerodynamic.
Ukusebenzisa izitayela nokubuyiselwa
Izinqubo zokuvuselela izitayela zihlukile kwezindiza ngayinye, kodwa ngokujwayelekile, umshayeli wezindiza angaqala ukuvuselelwa kwe-stall ngokukhulisa ukuhamba kwe-air phezu kwephiko. Lokhu kuvame ukufezwa ngokunciphisa isimo sengqondo sokugxila, ukulinganisa amaphiko, nokwanda kwamandla noma ukugxila. Uma iphiko liye laqedwa, kuvame ukuhamba kahle ukusebenzisa i-rudder ukuphakamisa iphiko, kunokuba i-ailerons.
Abashayeli bezimoto bajwayele ukuqhuba ama-stalls nokuphulukiswa njengengxenye yokuqeqeshwa kwabo, futhi kumele benze isitifiketi nokubuyiswa ukuze bathole isitifiketi esiyimfihlo noma sokuhweba.
Noma kunjalo, ukubuyekezwa kwendiza evamile ngokuvamile akubandakanyi izitayela, futhi ngenxa yalokho, abagibeli bezindiza bangakhohlwa ukuthi bangazibona kanjani izindiza ukuthi indiza iya esiteji. Ukusebenzisa izitezi nokuphumula ekuphuthumeni okusheshayo-futhi endaweni ephakeme yokuthola, ngokuqinisekile-kusiza abashayeli bezindiza baqaphele izibonakaliso zokuqala zesimo sokugcina ukuze bakwazi ukwenza izilungiso ezifanele.
