Isebenza Njani I-Aircraft Deicing?

Indlela Esebenza Ngayo Ukudilika Kweenqwelo-moya: Ukuqinisekisa Ukhuseleko Lweenqwelo-moya Zasebusika

Njengoko ubusika busondela, ishishini leenqwelo moya lijongene nomceli mngeni obalulekileyo: ukuqinisekisa ukuba iinqwelomoya azinamkhenkce nekhephu ngaphambi kokuba zisuke. Nokuba umkhenkce uqokeleleka kancinci kunokubeka emngciphekweni ukhuseleko lokubhabha, okwenza ukunqunyulwa kweenqwelo moya kube yinkqubo ebalulekileyo kwimisebenzi yemozulu ebandayo. Le nkqubo ayisusi nje kuphela umkhenkce okhoyo kunye nekhephu kodwa ikwathintela ukuphinda kuqokeleleke, ivumela imisebenzi yokubhabha ekhuselekileyo nethembekileyo.

Ukuqonda indlela esebenza ngayo i-deicing yeenqwelo-moya—kuquka ulwelo olusetyenziswayo, izixhobo ezibandakanyekayo, kunye nendima yeelori ezikhethekileyo ze-deicing—kugxininisa ukubaluleka kwayo ekugcineni ukhuseleko lweenqwelo-moya ngexesha lasebusika.

Kutheni iDeicing ibalulekile

Umkhenkce, iqabaka, okanye ikhephu kumphezulu wenqwelo-moya—ingakumbi amaphiko, umsila, kunye nomphezulu wolawulo—zinokuphazamisa kakhulu i-aerodynamics. Ezi zinto zingcolisayo zitshintsha imo ye-airfoil, zinciphise ukuphakama, zonyuse ukutsalwa, kwaye zinokuphazamisa impendulo yolawulo. Nokuba umaleko omncinci womkhenkce unokuba nefuthe elikhulu ekusebenzeni, okunokubangela iimeko eziyingozi ngexesha lokusuka okanye lokufika.

Ngenxa yesi sizathu, ukunqumla iinqwelomoya akunyanzelekanga—yinkqubo yokhuseleko enyanzelekileyo. Amagunya olawulo kunye neenqwelomoya anyanzelisa iingcamango ezingqongqo "zeenqwelomoya ezicocekileyo", oko kuthetha ukuba akukho qhwa, umkhenkce, okanye ikhephu elivumelekileyo kwiindawo ezibalulekileyo ngaphambi kokuba kubhabhe.

Inkqubo Yokucocwa Kwamanyathelo Amabini

Ukusika iinqwelomoya zanamhlanje kudla ngokuba namanqanaba amabini ahlukeneyo kodwa ahambelanayo: ukucheba kwaye ukulwa nobushushu.

1. Ukunyibilikisa

Eli nyathelo lokuqala lisusa iqabaka, umkhenkce, okanye ikhephu elikhoyo kumphezulu wenqwelo-moya. Ulwelo olushushu—ngokuqhelekileyo umxube we ipropylene glycol okanye i-ethylene glycol ngamanzi—itshizwa phantsi koxinzelelo phezu kwenqwelo-moya. Iimpawu zobushushu kunye neekhemikhali zolwelo ziyanyibilika ngokukhawuleza kwaye zikhulule izinto ezingcolisayo, ezithi emva koko zihlanjwe.

2. Ukuchasa i-Icing

Emva kokucoca, kusetyenziswa ulwelo oluchasene neqhwa ukuze kubonelelwe ukhuseleko lokubambaOlu lwelo luqinileyo, olunemibala eqaqambileyo lwenza umaleko okhuselayo obambezela ukuguquka komkhenkce nekhephu, nto leyo enika inqwelo-moya "ixesha lokuhlala" elichaziweyo phakathi konyango nokusuka. Oku kubaluleke kakhulu ngexesha lemvula enamandla okanye iimeko zokuqandisa.

Indima yeeLori zokuDaya iiDeicing

Iilori zokucoca—ezaziwa ngokuba zizithuthi zokukhupha i-ayisi okanye iirigi—ziyintsika yokusebenza kakuhle kokukhupha i-ayisi emhlabeni. Ezi zithuthi zikhethekileyo zenzelwe ukuhambisa usetyenziso oluchanekileyo nolulawulwayo lokukhupha i-ayisi kunye nolwelo oluchasene ne-ayisi kwiindawo ezinkulu zeenqwelo-moya.

Iimpawu eziphambili zeeLori zeDeicing zanamhlanje:

• Iinkqubo zolwelo ezifudumeleyo: Ulwelo lokukhupha amanzi luyafudunyezwa (ngesiqhelo ukuya kuma-60–80°C / 140–176°F) ukuze kuphuculwe ukusebenza kakuhle kokunyibilika komkhenkce ngelixa kuthintelwa ukonakala kumphezulu weenqwelo-moya.
• IiBoom Ezandisiweyo kunye neengalo Ezidibeneyo: Zixhotyiswe ngee-boom ezininzi ezisebenza kude, ezi lori zivumela abaqhubi ukuba bafikelele ngokukhuselekileyo nangokuchanekileyo kuzo zonke iindawo ezibalulekileyo zenqwelo-moya, kuquka amaphiko, umsila, kunye neendawo zokungena zenjini.
• IiNozzles ezichanekileyo kunye noLawulo lweSpray: Iinkqubo zomlomo eziphucukileyo ziqinisekisa ukusasazwa kolwelo ngokulinganayo, zinciphisa inkunkuma kwaye zigubungela kakhulu.
• Iinkqubo zoLawulo eziDibeneyo: Abaqhubi basebenzisa iindlela zokunxibelelana zedijithali ezikwibhodi ukujonga ubushushu bolwelo, uxinzelelo, izinga lokuhamba kwamanzi, amanqanaba eetanki, kunye neepateni zokutshiza ngexesha langempela—ukuqinisekisa ukusetyenziswa okuhlala kusenzeka nangokuhambelanayo.
• Izikhuselo zoKhuseleko kunye nokuSingqongileyo: Izinto ezinje ngokuvalwa kwezixhobo zongxamiseko, ukugcinwa kokuchitheka kwamanzi, kunye neenkqubo zokubuyisela ulwelo oluvaliweyo zinceda ekukhuseleni abasebenzi kunye nokusingqongileyo.

Inkqubo Yokwenza I-Deicing Ngokusebenzayo

Xa inqwelo-moya icwangciselwe ukuhamba phantsi kweemeko zomkhenkce, abasebenzi basemhlabeni baqala bahlole uhlobo kunye nobungakanani bongcoliseko. Ngokusekelwe kwidatha yemozulu kunye nezikhokelo zomenzi wolwelo, bamisela icebo elifanelekileyo lokususa i-icing kunye nelokulwa ne-icing.

Ilori yokukhupha i-ayisi ingena kwindawo yayo, kwaye umqhubi ubeka i-boom ukuze aqalise ukutshiza. Inkqubo iqala ngolwelo lokukhupha i-ayisi ukuze kususwe umkhenkce okhoyo, kulandele ngoko nangoko ulwelo oluchasene ne-ayisi apho kufuneka khona. Lonke umsebenzi udla ngokuthatha Imizuzu emi-5 ukuya kweli-15, kuxhomekeke kubukhulu beenqwelo-moya kunye neemeko zemozulu.

Xa sele igqityiwe, abasebenzi beenqwelo-moya bafumana ulwazi malunga uhlobo lolwelo olusetyenzisiweyo kwaye i ixesha elilindelekileyo lokubamba, nto leyo ebavumela ukuba badibane nolawulo lwezithuthi zomoya ukuze bahambe ngexesha elifanelekileyo.
