Isingeniso ku-Aerodynamics
I-Aerodynamics isifundo sokuthi amagesi ahlangana kanjani nemizimba ehambayo. Njengoba igesi esiyithanda kakhulu iwumoya, i-aerodynamics ngokuyisisekelo iwucwaningo lokuthi umoya uhamba kanjani ezintweni nokuthi lokhu kunyakaza kuzithinta kanjani lezo zinto. Kubashayeli bezindiza, ukuqonda i-aerodynamics kubalulekile ukuze kusetshenziswe ngokuphepha futhi ulawule indiza ngaphansi kwazo zonke izimo zokusebenza.
I-Aerodynamics igatsha le-fluid dynamics, elibandakanya ukucwaninga kwamagesi noketshezi olunyakazayo. Inezinhlobonhlobo zezinhlelo zokusebenza, kusukela ekuhlaziyeni ukugeleza kwegazi emzimbeni womuntu kuya ekufundeni imiphumela yomoya emabhulohweni. Kodwa kubashayeli bezindiza, ukusetshenziswa okuyinhloko kwe-aerodynamics kumkhakha wezokundiza, lapho isetshenziselwa khona ukuqonda nokubikezela ukuthi indiza izoziphatha kanjani lapho indiza.
Ucwaningo lwe-aerodynamics luyinkambu eyinkimbinkimbi edinga ukuqonda kwe-physics, mathematics, kanye ne-computational modelling. Nokho, ngisho nokuqonda okuyisisekelo kwezimiso ze-aerodynamics kungathuthukisa kakhulu ikhono lomshayeli wendiza lokundiza ngokuphepha nangempumelelo.
Ukubaluleka Kokuqonda I-Aerodynamics Kubashayeli Bezindiza
Ukuqonda i-aerodynamics kubalulekile kubashayeli bezindiza, njengoba imigomo ye-aerodynamics ithinta ngokuqondile ukusebenza, ukuzinza, nokulawula indiza. Ngokuqonda ukuthi izinguquko ekuphakameni, isivinini, kanye nokwakheka kungathinta kanjani ukusebenza kwendiza, abashayeli bezindiza bangenza izinqumo ezinolwazi ukuze baqinisekise izindiza eziphephile nezisebenza kahle.
Ukuwuqonda ngokuqinile kwenza abashayeli bezindiza baqonde ukuthi kungani indiza iziphatha ngendlela eziphatha ngayo ngaphansi kwezimo ezihlukahlukene. Ngokwesibonelo, kungani indiza ikhuphuka ngokushesha ngesivinini esithile? Noma kungani ingasabeli kahle ezindaweni eziphakeme? Ngokuqonda izimiso eziyisisekelo ze-aerodynamic, abashayeli bezindiza bangalindela lezi zinguquko futhi balungise izinhlelo zabo zendiza ngokufanele.
Ngaphezu kwalokho, ukuyiqonda kusiza abashayeli bamabhanoyi ukuba babikezele ngokunembile ukuthi indiza yabo izosabela kanjani kulokho okufakiwe kokulawula. Lokhu kuqonda kuthuthukisa ikhono labo lokulawula indiza, ikakhulukazi ezimweni ezingalindelekile noma eziphuthumayo, lapho izimpendulo ezisheshayo nezinembile zingasho umehluko phakathi kokuphila nokufa.
Izimiso Eziyisisekelo ze-Aerodynamics
Izimiso eziyisisekelo ze-aerodynamics zizungeza amandla asebenza endizeni lapho indiza. Lawa mandla ahlanganisa phakamisa, amandla adonsela phansi, ukusunduza, nokuhudula.
Ukuphakamisa amandla abheke phezulu aphikisana namandla adonsela phansi futhi avumele indiza ukuba ikhuphukele emoyeni. Ukwakhiwa kwe-lift kuyinqubo eyinkimbinkimbi ehilela ukuma kwamaphiko endiza, i-engeli lapho amaphiko ahlangana khona nomoya ozayo (i-angle yokuhlasela), kanye nesivinini nokuminyana komoya.
Amandla adonsela phansi amandla adonsela indiza emhlabeni. Ukuze indiza ihlale isezingeni elifanele, kufanele iphakamise indiza eyanele ukuze imelane namandla adonsela phansi.
I-Thrust amandla aqhubela indiza iye phambili emoyeni. Ngokuvamile ikhiqizwa izinjini, okungaba izinjini zejethi noma ama-propeller.
Ukuhudula amandla aphikisana nokuya phambili kwendiza. Kunezinhlobo ezimbili zokudonsa: i-parasitic drag, ehlanganisa ukuhudula kwefomu kanye nokungqubuzana kwesikhumba, kanye nokuhudula okubangelwayo, okuhlotshaniswa nesizukulwane sokuphakamisa.
Indlela I-Aerodynamics Eyithinta Ngayo Isayensi Yendiza
I-Aerodynamics idlala indima ebalulekile kwisayensi yokundiza. Izimiso ze-aerodynamics zinquma ukuthi indiza ikwazi kanjani ukusuka phansi, ukugcina ukundiza okulinganayo, ukuhamba emoyeni, kanye nokuhlala ngokuphepha.
Ibhalansi phakathi kwamandla okuphakamisa, amandla adonsela phansi, ukusunduza, nokuhudula inquma indlela yendiza yendiza. Ngokwesibonelo, lapho i-lift ekhiqizwa amaphiko endiza ilingana nesisindo sendiza, indiza izogcina indiza isezingeni elifanele. Uma i-lift idlula isisindo, indiza izokhuphuka. Uma isisindo sidlula i-lift, indiza izokwehla.
Ubudlelwano phakathi kwala mandla buphinde bunqume ukuthi indiza ihamba kanjani emoyeni. Ngokushintsha ukulingana kwala mandla, umshayeli wendiza angenza indiza ikhuphuke, yehle, ijike, noma ishintshe isivinini.
I-Aerodynamics kanye ne-Airplane Design
I-Aerodynamics iyisici esibalulekile ekwakhiweni kwendiza. Ukuma, usayizi, nokucushwa kwamaphiko, umzimba, nomsila wendiza konke kuklanywe ngokukhethekile ukuthuthukisa ukusebenza kwendiza ye-aerodynamic.
Amaphiko endiza aklanyelwe ukukhiqiza ukuphakama. Lokhu kufezwa ngokusebenzisa isimo esikhethekile, esibizwa ngokuthi i-airfoil, eyenza umoya ugeleze ngokushesha endaweni engaphezulu yephiko kunangaphansi, okwenza amandla abheke phezulu.
Umzimba wendiza, owaziwa nangokuthi i i-fuselage, yakhelwe ukunciphisa ukuhudula. Ivamise ukuhleleka, ibe nengaphambili elibushelelezi, eliyindilinga nangemuva elicijile.
Umsila wendiza, ohlanganisa iziqinisi eziqondile nezivundlile, uklanyelwe ukunikeza ukuzinza nokulawula. I-stabilizer eqondile ivimbela ukunyakaza okubheke eceleni (yaw), kuyilapho isizinzisi esivundlile sivimbela ukunyakaza okuya phansi naphezulu (iphimbo).
Imithelela Yesimo Sezulu ku-Aerodynamics
Izimo zezulu zingaba nomthelela omkhulu ku-aerodynamics, ngakho-ke, ukusebenza kwendiza. Umoya, izinga lokushisa, umswakama, nomfutho womkhathi konke kunengxenye ekunqumeni ukuthi indiza izoziphatha kanjani lapho indiza.
Umoya ungaphazamisa isivinini sendiza, lapho eya khona, nokuzinza kwayo. Imimoya evunguza phezulu (imimoya evunguza ngqo endizeni) ingabambezela indiza, kuyilapho imimoya engemuva (imimoya evunguza ngemva kwendiza) ingayisheshisa. Ama-crosswinds (imimoya evunguza ohlangothini) angabangela indiza ukuba ikhukhuleke endleleni.
Izinga lokushisa kanye nomswakama kungathinta ukuminyana komoya, okubuye kuthinte inani lokuphakanyiswa kwendiza okungakhiqizwa. Umoya oshisayo, onomswakama awuminyene kakhulu kunomoya obandayo, owomile, okusho ukuthi indiza kufanele indize ngokushesha ukuze ikhiqize inani elilinganayo lokuphakama ezimweni ezishisayo nezinomswakama njengoba ibingenza ezimweni ezibandayo nezomile.
Ukucindezela komkhathi nakho kudlala indima ebalulekile ku-aerodynamics. Ezindaweni eziphakeme, lapho umfutho womkhathi uphansi khona, indiza kufanele indize ngokushesha ukuze ikhiqize inani elilinganayo lokuphakama njengoba belingenza ezindaweni eziphansi.
I-Subsonic, Transonic, ne-Supersonic Flight
Izimiso ze-aerodynamics zingaziphatha ngendlela ehlukile ngesivinini esihlukile. Ikakhulukazi, ukuziphatha komoya kushintsha kakhulu njengoba indiza isondela futhi idlula isivinini somsindo.
Endizeni engaphansi (ngesivinini esingaphansi kwesivinini somsindo), umoya uziphatha njengoketshezi, ogeleza ngokushelela endizeni. Izimiso zokuphakamisa, ukuhudula, nokusunduza ziyasebenza njengoba zisebenza ngesivinini esiphansi.
Endizeni ye-transonic (isivinini esizungeze isivinini somsindo), ezinye izingxenye zomoya ozungeze endizeni zingase zihambe ngesivinini somsindo kanti ezinye zingahambi. Lokhu kungabangela amagagasi okwethuka endizeni, okungaholela ekwenyukeni okungazelelwe kokuhudula kanye nokuncipha kokuphakanyiswa.
Ekundizeni kwe-Supersonic (isivinini esingaphezu kwesivinini somsindo), umoya uziphatha njengegesi ecindezelayo. Amagagasi athuthumela endizeni, futhi izimiso zokuphakamisa, ukudonsa, nokududula zishintsha kakhulu. Ukuklama indiza ukuze indize ngesivinini esiphezulu kudinga ukuqonda okujulile kwalezi zinguquko.
