Kungani Ama-Aero Engine Blades Aklanywe Njengezakhiwo Ezikhululekile?

Injini ye-aero iqeda ukucindezelwa nokwandiswa kwegesi, futhi ikhiqize amandla amakhulu ngokusebenza kahle kakhulu. I-blade eqhubela indiza phambili yingxenye ekhethekile enenombolo enkulu yezimo eziyinkimbinkimbi, izidingo eziphezulu, kanye nemishini enzima.

Ukulungiswa okugobile kwamakhasi we-aero-engine kuyinkimbinkimbi ngokwedlulele, okudlulisa i-torque enkulu nokushisa okuphezulu kakhulu komlilo. Ngakho-ke, okokusebenza kwensimbi ngokuvamile kwenziwa ngezinto ezinokushisa okuphezulu nokumelana namandla aphezulu. Okwakuqala kwakungu-superalloy esekwe nge-polycrystalline nickel. Kamuva, kwenziwa i-polycrystalline blade enemingcele yamabele okusanhlamvu. Ukuqondiswa kwekristallini bekuhambisana nokuqondiswa kwamandla, futhi ukusebenza kuthuthukiswe kakhulu. Ekugcineni, yathuthukisa ekusetshenzisweni kabanzi kwezinto ze-titanium alloy. Ububanzi be-blade machining technology.

Njengomthwalo-eziveza ingxenye yenjini, izindwani zala mafeni azigxilile ngokuqinile enjinini, kepha zinamathele olimini nasemgodini wediski ye-fan ngokusebenzisa i-tenon. Kukhona igebe phakathi kwe-tenon ne-groove. Lapho ifeni ijikeleza kancane, ngaphansi kwamandla adonsela phansi, inhlamvu ngayinye izokwehla iye ngase-eksisi lapho isiseduze nendawo yehora leshumi nambili, futhi lapho isiseduze nendawo yehora lesithupha, izohamba iye ngase-eksisi amaslayidi aqonde kolunye uhlangothi. Ngenxa yalokhu, izindwani zabalandeli zashayisana zodwa ngenkathi kusatshalaliswa le naleya, kwazwakala umsindo wokuduma.

Isakhiwo se-mortise ne-tenon esihlanganisa ama-fan blade ne-fan plate sibizwa nge- "vertical tree" mortise, ngoba sibukeka njengesihlahla esiqonde mpo kanye nesihlahla se-fir, esikhombisa iton enamazinyo emise okwe-V kanye nomsele ophakathi kwe-tenon ne-tenon. Igebe elisobala lingenza kube lula ukuslayida kwamahhala kwetonon ngaphakathi kwebanga elithile.

Kungani Ama-Aero Engine Blades Aklanywe Njengezakhiwo Ezikhululekile?

Lapho umshayeli wenjini ezungeza ngokushesha futhi edlula isivinini esibucayi, ukujikeleza umphini iqala ukusondela esikhungweni sayo sejiyomethri ngenxa yokuqina kwayo, bese iwela isikhungo sejiyometri bese isondela ekungalinganeni kwayo. Ngalesi sikhathi, ukuqondiswa kwamandla we-centrifugal atholwe yi-blade kuqala kusuka ekujikelezeni okusha umphini futhi idlula ngesikhundla se-blade. Ingxenye ekuqondeni okuguquguqukayo kwediski ye-turbine ikhomba ohlangothini oluhlukile endaweni engalinganiseli, okwenza izindwani ziphambuke kule ndlela, ngaleyo ndlela ziphinde zilungise indawo engalingani ukuze isikhungo samandla adonsela phansi siseduze nesikhungo saso sejometri, ngaleyo ndlela ukunciphisa ukudlidliza.

Le nqubo inamandla amakhulu, ngakho-ke ukudlidlizela kwesiphepheli nganoma yisiphi isivinini esikhulu kungancishiswa ngamandla, futhi i-engeli yamakhasi ehlobene nokuqondiswa okunamandla kwediski ye-turbine iyashintsha ngezikhathi ezithile, ngakho-ke izindwani zidinga ukujikisa kwesokunxele nakwesokudla.

Ukuze kuvunyelwe izindwani ukuba zishintshe ngokukhululeka kuze kube sezingeni elithile, ama-blade awabekiwe ngokuphelele kudiski we-turbine, kepha ashiywa anezikhala, futhi amahlombe awakwazi ukusondela ngokuphelele kuzincazelo eziseduze, futhi ukuvumela ama-blades ukuba ajike . Kuyiqiniso ukuthi hhayi kuphela ama-fan we-fan avulekile, kepha ama-blade we-compressor yonke akhululekile.
