Inqubo yokupholisa ngaphambi kokufakwa kwepayipi

Kuyo yonke inqubo yokudluliselwa kwepayipi loketshezi oluyi-cryogenic, ngaphambi kokusungula isimo sokudluliselwa esizinzile, kuzoba nohlelo lwangaphambi kokupholisa kanye nohlelo lwamapayipi ashisayo kanye nenqubo yemishini yokwamukela, okungukuthi, inqubo yangaphambi kokupholisa. Kule nqubo, ipayipi kanye nemishini yokwamukela kumele imelane nokucindezeleka okukhulu kokuncipha kanye nengcindezi yomthelela, ngakho-ke kufanele ilawulwe.

Ake siqale ngokuhlaziya inqubo.

Yonke inqubo yokupholisa ngaphambi kokupholisa iqala ngenqubo yokuhwamuka enamandla, bese kuvela ukugeleza kwezigaba ezimbili. Ekugcineni, ukugeleza kwesigaba esisodwa kuvela ngemuva kokuba uhlelo selupholile ngokuphelele. Ekuqaleni kwenqubo yokupholisa ngaphambi kokupholisa, izinga lokushisa lodonga ngokusobala lidlula izinga lokushisa lokugcwala koketshezi oluyi-cryogenic, futhi lidlula ngisho nezinga lokushisa eliphezulu loketshezi oluyi-cryogenic — izinga lokushisa eliphakeme kakhulu lokushisa. Ngenxa yokudluliselwa kokushisa, uketshezi oluseduze nodonga lwetyhubhu luyashiswa futhi lushiswe ngokushesha ukuze kwakheke ifilimu yomphunga, ezungeze ngokuphelele udonga lwetyhubhu, okungukuthi, ukubila kwefilimu kwenzeka. Ngemva kwalokho, ngenqubo yokupholisa ngaphambi kokupholisa, izinga lokushisa lodonga lwetyhubhu liyehla kancane kancane ngaphansi kwezinga lokushisa lokushisa okuphezulu, bese kwakheka izimo ezinhle zokubila kokuguquka kanye nokubila kwebhamuza. Ukushintshashintsha okukhulu kwengcindezi kwenzeka phakathi nale nqubo. Lapho ukupholisa ngaphambi kokupholisa kwenziwa esigabeni esithile, amandla okushisa epayipi kanye nokuhlasela kokushisa kwemvelo ngeke kushise uketshezi oluyi-cryogenic ekushiseni kokugcwala, futhi isimo sokugeleza kwesigaba esisodwa sizovela.

Enkambisweni yokuhwamuka okukhulu, kuzokhiqizwa ukugeleza okukhulu kanye nokuguquguquka kwengcindezi. Kuyo yonke inqubo yokuguquguquka kwengcindezi, ingcindezi ephezulu eyakheka okokuqala ngemva kokuba uketshezi olucryogenic lungene ngqo epayipini elishisayo yi-amplitude ephezulu kuyo yonke inqubo yokuguquguquka kwengcindezi, futhi igagasi lokucindezela lingaqinisekisa amandla okucindezela kohlelo. Ngakho-ke, igagasi lokuqala lokucindezela kuphela elivame ukufundwa.

Ngemva kokuvulwa kwevalvu, uketshezi oluyi-cryogenic lungena ngokushesha epayipini ngaphansi kwesenzo somehluko wokucindezela, futhi ifilimu yomusi ekhiqizwa ukuhwamuka ihlukanisa uketshezi odongeni lwepayipi, yakha ukugeleza kwe-axial okugxilile. Ngoba i-coefficient yokumelana komphunga incane kakhulu, ngakho-ke izinga lokugeleza koketshezi oluyi-cryogenic likhulu kakhulu, ngokuqhubeka phambili, izinga lokushisa loketshezi ngenxa yokumuncwa kokushisa futhi likhuphuka kancane kancane, ngokufanele, ingcindezi yepayipi iyanda, ijubane lokugcwalisa liyehla. Uma ipayipi lide ngokwanele, izinga lokushisa loketshezi kumele lifinyelele ekugcwaleni ngesikhathi esithile, lapho uketshezi luyeka ukuqhubekela phambili. Ukushisa okuvela odongeni lwepayipi kuya kuketshezi oluyi-cryogenic kusetshenziselwa ukuhwamuka, ngalesi sikhathi ijubane lokuhwamuka liyakhuphuka kakhulu, ingcindezi epayipini nayo iyakhuphuka, ingafinyelela izikhathi ezingu-1.5 ~ 2 zokucindezela kokungena. Ngaphansi kwesenzo somehluko wokucindezela, ingxenye yoketshezi izobuyiselwa emuva ethangini lokugcina uketshezi oluyi-cryogenic, okuholela ekutheni isivinini sokukhiqizwa komswakama sibe sincane, futhi ngenxa yokuthi ingxenye yomswakama ekhiqizwa ekukhishweni kokuphuma kwepayipi, ukwehla komfutho wepayipi, ngemva kwesikhathi esithile, ipayipi lizophinde limise uketshezi ezimweni zomehluko wokucindezela, lesi simo sizovela futhi, ngakho-ke siphindaphindwa. Kodwa-ke, enkambisweni elandelayo, ngoba kukhona ukucindezela okuthile kanye nengxenye yoketshezi epayipini, ukwanda kokucindezela okubangelwa uketshezi olusha kuncane, ngakho-ke ukuphakama kokucindezela kuzoba kuncane kunesiqongo sokuqala.

Kuyo yonke inqubo yokupholisa ngaphambi kokupholisa, uhlelo alugcini nje ngokuthwala umthelela omkhulu wamagagasi okucindezela, kodwa futhi kufanele lubhekane nokucindezeleka okukhulu kokuncipha ngenxa yokubanda. Isenzo esihlangene salokhu okubili singadala umonakalo wesakhiwo ohlelweni, ngakho-ke kufanele kuthathwe izinyathelo ezidingekayo ukuze lulawulwe.

Njengoba izinga lokugeleza ngaphambi kokupholisa lithinta ngqo inqubo yokupholisa kanye nosayizi wokucindezeleka kokuncipha okubandayo, inqubo yokupholisa ingalawulwa ngokulawula izinga lokugeleza ngaphambi kokupholisa. Umgomo wokukhetha ofanele wezinga lokugeleza ngaphambi kokupholisa ukufinyeza isikhathi sokupholisa ngokusebenzisa izinga lokugeleza elikhulu ngaphambi kokupholisa ngesisekelo sokuqinisekisa ukuthi ukushintshashintsha kwengcindezi kanye nokucindezeleka kokuncipha okubandayo akudluli ububanzi obuvunyelwe bemishini namapayipi. Uma izinga lokugeleza ngaphambi kokupholisa lincane kakhulu, ukusebenza kokufakwa kwepayipi akulungile epayipini, kungenzeka lingafinyeleli esimweni sokupholisa.

Enkambisweni yokupholisa ngaphambi kokupholisa, ngenxa yokuvela kokugeleza kwezigaba ezimbili, akunakwenzeka ukukala izinga lokugeleza langempela nge-flowmeter evamile, ngakho-ke ayikwazi ukusetshenziswa ukuqondisa izinga lokugeleza ngaphambi kokupholisa. Kodwa singahlulela ngokungaqondile ubukhulu bokugeleza ngokuqapha ingcindezi yangemuva yesitsha esamukelayo. Ngaphansi kwezimo ezithile, ubudlelwano phakathi kwengcindezi yangemuva yesitsha esamukelayo kanye nokugeleza kwangaphambi kokupholisa kunganqunywa ngendlela yokuhlaziya. Lapho inqubo yokupholisa ngaphambi kokupholisa iqhubekela esimweni sokugeleza kwesigaba esisodwa, ukugeleza kwangempela okulinganiswe yi-flowmeter kungasetshenziswa ukuqondisa ukulawula ukugeleza kwangaphambi kokupholisa. Le ndlela ivame ukusetshenziswa ukulawula ukugcwaliswa kwe-cryogenic liquid propellant yerokhethi.

Ukushintsha kwengcindezi yangemuva yesitsha esamukelayo kuhambisana nenqubo yangaphambi kokupholisa kanje, engasetshenziswa ukwahlulela ngokwekhwalithi isigaba sangaphambi kokupholisa: lapho amandla okukhipha umoya wesitsha esamukelayo engaguquki, ingcindezi yangemuva izokhula ngokushesha ngenxa yokuhwamuka koketshezi oluyi-cryogenic ekuqaleni, bese kancane kancane ibuyela emuva ngokuncipha kwezinga lokushisa lesitsha esamukelayo kanye nepayipi. Ngalesi sikhathi, amandla okupholisa ayanda.

Ngibheke esihlokweni esilandelayo ukuze ngithole eminye imibuzo!
