SpaceX izagerageza kubika ububiko bwa Starship propellant kubwa mbere

Mu mpinduramatwara iheruka mu mugani wa SpaceX yihariye ya Starship yoherejwe ikigega cyo kubika ububiko, isosiyete isa nkaho yahisemo gusubira inyuma kubaka prototype ntoya ikoreshwa mugupima gusa.
Azwi nka "ikigega cyo kugerageza," ibyubatswe bito bito byegeranijwe byihuse biva mubice byibikoresho bishaje byubutaka (GSE) byavanyweho muri Nyakanga mucyumweru gishize cyangwa hafi. SpaceX yarangije ikigega cya mbere cya Starship gikomoka kuri moteri yo kubika muri Mata 2021, maze ihita izunguruka iyi tank (GSE1) n'iya kabiri (GSE2) kuva aho yubatswe kugeza ku cyerekezo cyo gutangiza orbital mu byumweru bike gusa. Hatarenze ukwezi, SpaceX nayo yarangije ikigega cya GSE 3, nubwo ibintu bisa nkaho byahise bigwa mu kajagari nyuma yibyo.
Nyuma y'amezi atatu gusa, amaherezo GSE3 yajyanywe kuri - hanyuma ishyirwaho - ku nkunga ifatika y’icyogajuru cyogajuru icyogajuru cya mbere cyoherejwe na orbital, hanyuma nyuma yo guhindura ibintu byinshi hamwe na tanki ya GSE # 5 na # 6 Nyuma yintambwe. Ikitazwi cyane ni ukubera iki ibicuruzwa bya GX bya SpaceX byabigenewe byahagaritswe nyuma gato yuko bitangira, kuki nta na kimwe muri tanki eshanu zingana na Starship zashyizwe ku makarito yashyizweho cyangwa ngo gikorwe ubwoko ubwo ari bwo bwose, cyangwa impamvu byasaga naho kubaka bikenewe. Yahinduwe nyuma. Ariko, ntawabura kuvuga ko SpaceX nshya ya GSE “test tank” ubu iri hagati yibanga.
Kubwamahirwe, kugaragara byihuse bya tank ya mbere ya GSE ya SpaceX byibuze byatumye abantu bamenyera amateka magufi ariko akajagari ya Starship orbital launch pad propellant tank. Ibigega by'ibizamini ntabwo ari shyashya, kandi kuva Ikizamini cya Tank 1 cyatangiye kujya mu kigo cya SpaceX cyo gutangiza (no kugerageza) muri Mutarama 2020, cyagize uruhare rukomeye mu iterambere rya Starship. Mu mezi 20 yakurikiyeho, SpaceX yubatse kandi igerageza ibigega birindwi bito byo gupima, ibyinshi muri byo ntibyarokotse.
Hatitawe ku byangiritse nkana, buri kigega cyipimisha gifasha neza SpaceX kwemeza tekinike nshya yo gukora, ibikoresho bitandukanye, hamwe nubunini bwuruhu rutandukanye, kandi mubisanzwe birihuta kandi bihenze kuruta ikusanyamakuru ryemewe na prototypes yuzuye. Kurugero, vuba aha, SpaceX isa nkaho yagerageje neza ikizamini cyikigereranyo kiremereye cyane, igashyira prototype muri azote yuzuye ya azote, kandi igakoresha silinderi ya hydraulic kugirango igereranye moteri ya Raptor icyenda kumiterere ya disiki idafite gihamya.
Noneho, SpaceX imaze gukira mubyerekezo kandi yibuka imikorere yikigega. Isosiyete yakusanyije prototype ntoya ya GSE, birashoboka ko igenzura niba ikigega cyayo kibika ibicuruzwa gishobora gutwara urukurikirane rutandukanye cyane n’icyogajuru cy’imibumbe. Imiterere baturuka. Muri uru rubanza, ikigega cya GSE cyubatswe mu gice cyakuweho cya tank ya GSE # 4. Mubyukuri, nyuma yuko tank ikuweho kubwimpamvu zitazwi ukwezi gushize, igice cyo hejuru (igice cyimbere cyimbere) cyaciwe burundu na GSE4.
Mu mezi make ashize, nubwo hari ibitunguranye bitunguranye mu gukora no gushyiramo tanki ya GSE, abakozi ba SpaceX gahoro gahoro ariko buhoro buhoro basudira impeta zicyuma (stiffeners) kugeza hanze ya GSE1, GSE2, na GSE3. Igihe GSE5 na GSE6 amaherezo berekeje kuri kaburimbo, bari barashyizeho izo stiffeners igihe bagiye, bivuze ko ikintu cyose cyakandagiye SpaceX gishobora kuba cyubatswe. Ikizamini cya GSE4 kirimo kandi imbaraga zo hanze kuri buri cyuma kizengurutse (impeta yimpeta cyangwa guhuza dome).
Mugihe SpaceX yubatse (cyangwa itarigeze) yubaka ibigega byayo byo kubika GSE mu mezi make, rwiyemezamirimo usanzwe akoranya iminara y’amazi n’ibigega byo kubikamo aho yubatse ubwikorezi bunini bwa metero 12 (~ 40 ft) ubwabwo. Ufatwa nka "cryogenic shells", nkuko izina ryabo ribivuga, ibyo bigega byagenewe kuzenguruka rwose tanks ya GSE ya SpaceX. SpaceX izakoresha ibyo bishishwa kugirango ikingire ibigega byayo byoroheje bikikijwe n'icyuma gikomeza ibyuma bya kirogenike kugirango bishoboke kugeza igihe kirekire gishoboka. Ariko, uburyo bazigunga ntibisobanutse.
Hashingiwe ku cyemezo gisa nkicyisubiraho cyo gushimangira inyuma yibi bigega bya GSE, ubwumvikane rusange buherutse ni uko SpaceX ishaka guhumeka byibuze mu cyuho kiri hagati yikigega na tank. SpaceX irashobora kandi gufata inzira itandukanye kandi igahatira icyuho (bishoboka) hamwe na gaze ya insuline nka azote. Urujijo rwiyongereye ruva muburyo ibigega bya Starship byateguwe muburyo bwo gushyigikira icyogajuru nyacyo (gikora mu cyuho cyuzuye) bidakenewe imbaraga zo hanze.
Byongeye kandi, biragaragara ko SpaceX itarubaka ultra-ntoya ya cryogenic shell cyangwa beto yo gushiraho ikigega cyayo cya GSE4, bivuze ko mubyukuri ari ingirakamaro mugupima imitwaro imwe gusa tanks ya GSE izahura nazo amaboko. Byongeye kandi, urebye ko SpaceX yarangije ibigega bitandatu muri birindwi bya GSE ya padiri ya orbital hamwe na kirotobes zabo zose uko ari zirindwi, ibibazo byose byavumbuwe mugihe cyo gupima GSE4 birashobora gutuma byoroshye amezi menshi yo gukora no gutinda. Ariko, niba ufite amahirwe, GSE4 izahanagura inzira ya SpaceX kugirango irangize umuyoboro, ikingira kandi igashyira mubikorwa ububiko bwa peteroli bwa Starship bwa mbere binyuze mubikorwa byo kugerageza.
