Isebenza Kanjani I-Aircraft Deicing?

Indlela Okusebenza Ngayo Ukuqopha Izindiza: Ukuqinisekisa Ukuphepha Kwezindiza Zasebusika

Njengoba ubusika busondela, imboni yezindiza ibhekene nenselele enkulu: ukuqinisekisa ukuthi izindiza azinaqhwa neqhwa ngaphambi kokusuka. Ngisho nokuqongelela okuncane kweqhwa kungalimaza ukuphepha kwezindiza, okwenza ukuqongelela izindiza kube inqubo ebalulekile ekusebenzeni kwesimo sezulu esibandayo. Le nqubo ayisusi nje kuphela iqhwa neqhwa elikhona kodwa futhi ivimbela ukuqongelela kabusha, okwenza kube lula ukusebenza kwezindiza okuphephile nokuthembekile.

Ukuqonda indlela okusebenza ngayo ukuqoqwa kwezindiza—okuhlanganisa uketshezi olusetshenziswayo, imishini ehilelekile, kanye nendima yamaloli akhethekile okuqoqwa kwezindiza—kugcizelela ukubaluleka kwayo ekugcineni ukuphepha kwezindiza ngesikhathi sasebusika.

Kungani Ukusika Kubalulekile

Iqhwa, isithwathwa, noma iqhwa ezindaweni zendiza—ikakhulukazi amaphiko, umsila, kanye nezindawo zokulawula—kungaphazamisa kakhulu i-aerodynamics. Lezi zinto ezingcolisayo zishintsha ukuma kwe-airfoil, zinciphise ukuphakama, zandise ukuhudula, futhi zingaphazamisa impendulo yokulawula. Ngisho nengqimba encane yeqhwa ingaba nomthelela omkhulu ekusebenzeni, okungase kuholele ezimweni eziyingozi ngesikhathi sokusuka noma sokufika.

Ngenxa yalesi sizathu, ukusika izindiza akuyona into ongayikhetha—kuyinqubo yokuphepha ephoqelekile. Iziphathimandla ezilawulayo kanye nezindiza ziphoqelela imiqondo eqinile "yezindiza ezihlanzekile", okusho ukuthi akukho sithwathwa, iqhwa, noma iqhwa elivunyelwe ezindaweni ezibalulekile ngaphambi kokundiza.

Inqubo Yokususa Izinyathelo Ezimbili

Ukukhishwa kwezindiza zanamuhla ngokuvamile kuqukethe izigaba ezimbili ezihlukile kodwa ezihambisanayo: ukuhlobisa futhi ukulwa nokushisa iqhwa.

1. Ukuhlanza

Lesi sinyathelo sokuqala sisusa isithwathwa esikhona, iqhwa, noma iqhwa ebusweni bendiza. Uketshezi olushisayo—ngokuvamile ingxube ye- i-propylene glycol noma i-ethylene glycol ngamanzi—kufafazwa ngaphansi kwengcindezi phezu kwendiza. Izakhiwo zokushisa namakhemikhali zalolu ketshezi ziyancibilika ngokushesha futhi zikhulule ukungcola, okube sekugezwa ngamanzi.

2. Ukulwa neqhwa

Ngemva kokukhipha i-ice, kusetshenziswa uketshezi olulwa ne-icing ukuze lunikeze isivikelo sokubamba. Lolu ketshezi oluqinile, oluvame ukuba nombala ogqamile lwakha ungqimba oluvikelayo olubambezela ukuguqulwa kweqhwa neqhwa, okunikeza indiza "isikhathi sokuma" esichaziwe phakathi kokwelashwa nokusuka. Lokhu kubaluleke kakhulu ngesikhathi semvula enamandla noma izimo zokuqandisa.

Indima Yamaloli Okukhipha Iqhwa

Amaloli okuhlanza i-deicing—ezaziwa nangokuthi izimoto zokusika iqhwa noma imishini yokusika iqhwa—ziwumgogodla wemisebenzi yokusika iqhwa ephumelelayo. Lezi zimoto ezikhethekile zenzelwe ukuletha ukusetshenziswa okunembile nokulawulwayo kokusika iqhwa kanye noketshezi olulwa neqhwa ezindaweni ezinkulu zezindiza.

Izici Eziyinhloko Zamaloli Esimanje Okuhlanza Izinkuni:

• Izinhlelo Zoketshezi Ezishisayo: Uketshezi lwe-deicing luyashiswa (ngokuvamile lufike ku-60–80°C / 140–176°F) ukuze kwandiswe ukusebenza kahle kokuncibilika kweqhwa ngenkathi kugwenywa ukulimala ezindaweni zezindiza.
• Ama-Boom Anwebekayo Nezingalo Ezihlanganisiwe: Njengoba zihlonyiswe ngama-boom amaningi asebenza kude, la malori avumela abaqhubi ukuthi bafinyelele ngokuphephile nangokunembile kuzo zonke izindawo ezibalulekile zendiza, okuhlanganisa amaphiko, umsila, kanye nezindawo zokungena zenjini.
• Ama-Nozzles Aqondile kanye Nokulawula Ukufutha: Izinhlelo zomlomo ezithuthukisiwe ziqinisekisa ukusatshalaliswa koketshezi okufanayo, zinciphisa imfucuza futhi zikhulisa ukumbozwa.
• Izinhlelo Zokulawula Ezihlanganisiwe: Abaqhubi basebenzisa izixhumi zedijithali ezingaphakathi ukuze baqaphe izinga lokushisa koketshezi, ingcindezi, izinga lokugeleza, amazinga ethangi, kanye namaphethini okufafaza ngesikhathi sangempela—ukuqinisekisa ukusetshenziswa okuhambisanayo nokuhambisanayo.
• Izivikelo Zokuphepha NezemveloIzici ezifana nokuvalwa kwezimo eziphuthumayo, ukugcinwa kokuchitheka, kanye nezinhlelo zokubuyisa uketshezi oluvaliwe kusiza ukuvikela abasebenzi kanye nemvelo.

Inqubo Yokwenza I-Deicing Esebenzayo

Uma indiza ihlelelwe ukuhamba ezimweni ezibandayo, abasebenzi basemhlabeni baqala ngokuhlola uhlobo kanye nezinga lokungcola. Ngokusekelwe kudatha yesimo sezulu kanye neziqondiso zomkhiqizi woketshezi, banquma isu elifanele lokususa iqhwa kanye nelokulwa neqhwa.

Iloli lokukhipha iqhwa liya endaweni yalo, bese umqhubi esebenzisa i-boom ukuze aqale ukufafaza. Inqubo iqala ngokukhipha iqhwa ukuze kusulwe iqhwa elikhona, kulandelwe ngokushesha uketshezi olulwa neqhwa lapho kudingeka khona. Umsebenzi wonke uvame ukuthatha Imizuzu emi-5 kuya kweyi-15, kuye ngobukhulu bendiza kanye nezimo zezulu.

Uma sekuqediwe, abasebenzi bendiza bathola ulwazi mayelana uhlobo loketshezi olusetshenzisiwe kanye isikhathi sokulinda esilindelekile, okubavumela ukuthi baxhumane nabaqondisi bezindiza ukuze basuke ngesikhathi.
