United Launch Alliance ikhoza kuyika cryogenic methane ndi madzi okosijeni pamalo ake oyesera roketi ya Vulcan ku Cape Canaveral koyamba m'masabata akubwerawa pamene ikukonzekera kuponya roketi yake ya Atlas 5 ya m'badwo wotsatira pakati pa maulendo ake. Kuyesa kwakukulu kwa maroketi omwe adzagwiritse ntchito njira yomweyo yotulutsira roketi m'zaka zikubwerazi.
Pakadali pano, ULA ikugwiritsa ntchito roketi yake ya Atlas 5 yogwira ntchito poyesa zinthu za roketi yamphamvu kwambiri ya Vulcan Centaur isanafike ndege yoyamba ya galimoto yatsopano yoyambitsa. Injini yatsopano ya BE-4 yochokera ku kampani ya mlengalenga ya Jeff Bezos ya Blue Origin yakonzeka ndipo ikupita patsogolo ndi kuyambitsidwa koyamba kwa Vulcan.
Mkulu wa bungwe la ULA, John Albon, anati kumayambiriro kwa mwezi wa Meyi kuti roketi yoyamba ya Vulcan iyenera kukhala yokonzeka kuponyedwa kumapeto kwa chaka.
Kutulutsidwa koyamba kwa Vulcan kungachitike kumapeto kwa chaka chino kapena kumayambiriro kwa chaka cha 2022, adatero Col. Robert Bongiovi, mkulu wa Space Force's Space and Missile Systems Center's Space and Missile Systems Center, Lachitatu. Gulu la Space Force lidzakhala kasitomala wamkulu wa ULA pamene roketi ya Vulcan ikuchita maulendo awiri otsimikizira isanayambe ntchito yake yoyamba yankhondo yaku US, USSF-106, kumayambiriro kwa chaka cha 2023.
Kutulutsidwa kwa satellite ya asilikali aku US Atlas 5 Lachiwiri kunayesa mtundu watsopano wa injini ya RL10 upper stage yomwe idzawuluka pa Centaur upper stage ya rocket ya Vulcan. Kutulutsidwa kwotsatira kwa Atlas 5 mu June kudzakhala rocket yoyamba kugwiritsa ntchito Vulcan. . Monga chishango chonyamula katundu chopangidwa ku USA, osati ku Switzerland.
Kumanga ndi kuyesa makina atsopano oyendetsera roketi ya Vulcan Centaur kwatsala pang'ono kutha, anatero Ron Fortson, mkulu komanso woyang'anira wamkulu wa ntchito zoyambitsa ku ULA.
"Iyi idzakhala njira yoyambira yogwiritsira ntchito maulendo awiri," adatero Fordson posachedwapa pamene ankatsogolera atolankhani paulendo wa Launch Pad 41 ku Cape Canaveral Space Force Station. "Palibe amene adachitapo izi kale, makamaka kuyambitsa Atlas ndi mzere wosiyana kwambiri wa zinthu za Vulcan pa nsanja yomweyo."
Injini ya RD-180 ya ku Russia ya roketi ya Atlas 5 imagwira ntchito pa kerosene yosakanikirana ndi mpweya wamadzimadzi. Ma injini awiri a BE-4 Vulcan omwe ndi oyamba amayendetsa ntchito pa mpweya wachilengedwe wosungunuka kapena mafuta a methane, zomwe zimafuna kuti ULA ikhazikitse matanki atsopano osungiramo zinthu pa Pulatifomu 41.
Matanki atatu osungira methane okwana malita 100,000 ali kumpoto kwa Launch Pad 41. Kampaniyo, yomwe ndi yogwirizana ndi Boeing ndi Lockheed Martin, inakonzanso njira yamadzi yolandirira mawu ya launch pad, yomwe imachepetsa phokoso lamphamvu lomwe limapangidwa ndi launch pad.
Malo osungiramo haidrojeni yamadzimadzi ndi okosijeni yamadzimadzi ku Launch Pad 41 nawonso adakonzedwa kuti agwirizane ndi gawo lalikulu la Centaur pamwamba, lomwe lidzawuluke pa roketi ya Vulcan.
Gawo latsopano la Centaur 5 la roketi ya Vulcan lili ndi mainchesi 5.4 m'mimba mwake, loposa kawiri kuposa gawo la Centaur 3 la pamwamba pa Atlas 5. Centaur 5 idzayendetsedwa ndi mainjini awiri a RL10C-1-1, osati injini yomweyo ya RL10 yomwe imagwiritsidwa ntchito pa ma Atlas 5 ambiri, ndipo idzanyamula mafuta ochulukirapo kawiri ndi theka kuposa Centaur yomwe ilipo pano.
Fordson adati ULA yamaliza kuyesa matanki atsopano osungiramo methane ndipo yatumiza madzi oundana kudzera m'mizere yoperekera madzi pansi kupita kumalo oyambitsira magetsi ku Pad 41.
"Tinadzaza matanki awa kuti tidziwe za malo awo," adatero Fordson. "Tili ndi mafuta omwe akuyenda m'mizere yonse. Timatcha izi kuti mayeso oyenda ozizira. Tinadutsa m'mizere yonse mpaka kulumikizana ndi VLP, yomwe ndi nsanja yotulutsira Vulcan, ndi roketi ya Vulcan yomwe yatulutsidwa. "
Vulcan Launch Platform ndi chida chatsopano choyendetsera ndege chomwe chidzanyamula roketi ya Vulcan Centaur kuchokera ku chipangizo cha ULA chomwe chili ndi vertical integrated kupita ku Launch Pad 41. Kumayambiriro kwa chaka chino, ogwira ntchito pansi adanyamula siteji yapakati ya Vulcan Pathfinder pa pulatifomu ndikuyika roketiyo pa daunch pa round yoyamba yoyesera pansi.
ULA imasunga ma VLP ndi Vulcan Pathfinder pa malo ogwirira ntchito a Cape Canaveral Space Operations Center omwe ali pafupi pomwe kampaniyo ikukonzekera roketi yake yatsopano ya Atlas 5 kuti inyamuke ndi satelayiti yochenjeza ya asilikali ya SBIRS GEO 5.
Pambuyo poyambitsa bwino Atlas 5 ndi SBIRS GEO 5 Lachiwiri, gulu la Vulcan lidzasuntha roketi kubwerera ku Launch Pad 41 kuti lipitirize kuyesa Pathfinder. ULA iyamba kuyika roketi ya Atlas 5 mkati mwa VIF, yomwe ikuyembekezeka kuyambitsidwa pa June 23 pa ntchito ya Space Force ya STP-3.
Kampani ya ULA ikukonzekera kuyika mafuta pa galimoto yoyambitsa ya Vulcan koyamba, kutengera mayeso oyamba a makina oyendetsera pansi.
"Nthawi ina tikatulutsa ma VLP, tidzayamba kuchita mayeso awa odutsa magalimoto," adatero Fortson.
Galimoto ya Vulcan Pathfinder inafika ku Cape Canaveral mu February ndi roketi ya ULA kuchokera ku fakitale ya kampaniyo ku Decatur, Alabama.
Kutulutsidwa kwa Lachiwiri kunali chizindikiro cha ulendo woyamba wa Atlas 5 m'miyezi yoposa isanu ndi umodzi, koma ULA ikuyembekeza kuti liwiroli lipitirire chaka chino. Pambuyo pa kutulutsidwa kwa STP-3 pa June 23, kutulutsidwa kwotsatira kwa Atlas 5 kukukonzekera pa July 30, komwe kudzaphatikizapo kuyesa ndege ya Boeing's Starliner crew module.
"Tiyenera kumaliza ntchito pa Vulcan pakati pa kutulutsidwa," adatero Fordson. "Tidzatulutsa STP-3 posachedwa pambuyo pake. Ali ndi zenera laling'ono loti agwire ntchito, ayesere ndikuyesa, kenako tidzayika galimoto ina."
Roketi ya Vulcan Pathfinder imayendetsedwa ndi malo oyesera injini ya Blue Origin ya BE-4, ndipo mayeso a thanki yake athandiza mainjiniya kudziwa momwe angaikire mafuta mu Vulcan patsiku loyambitsa.
"Tidzamvetsa katundu yense ndi momwe amagwirira ntchito ndikukulitsa CONOPS yathu (lingaliro la ntchito) kuyambira pamenepo," adatero Fordson.
ULA ili ndi luso lalikulu pogwiritsa ntchito hydrogen yamadzi ozizira kwambiri, mafuta ena a roketi omwe amagwiritsidwa ntchito m'gulu la maroketi a Delta 4 a kampaniyi komanso ma stage apamwamba a Centaur.
"Onse anali ozizira kwambiri," anatero Fordson. "Ali ndi makhalidwe osiyana. Tikungofuna kumvetsetsa momwe zimakhalira panthawi yopatsirana."
"Mayeso onse omwe tikuchita pano ndi kumvetsetsa bwino za katundu wa mpweya uwu ndi momwe umagwirira ntchito tikauyika mgalimoto," adatero Fordson. "Ndicho chomwe tidzachita m'miyezi ingapo ikubwerayi."
Ngakhale kuti makina a Vulcan oyendetsera pansi ali ndi mphamvu zambiri, ULA ikugwiritsa ntchito makina ake oyendetsera ntchito poyesa ukadaulo woyendetsa ndege za m'badwo wotsatira.
Mtundu watsopano wa injini ya Aerojet ya Rocketdyne RL10 pa Centaur upper stage wawululidwa Lachiwiri. Mtundu waposachedwa wa injini ya hydrogen, yotchedwa RL10C-1-1, wagwira ntchito bwino ndipo ndi wosavuta kupanga, malinga ndi ULA.
Injini ya RL10C-1-1 ili ndi nozzle yayitali kuposa injini yomwe idagwiritsidwa ntchito pamaroketi am'mbuyomu a Atlas 5 ndipo ili ndi injector yatsopano yosindikizidwa ndi 3D, yomwe idapanga ulendo wake woyamba, adatero Gary Harry, wachiwiri kwa purezidenti wa boma ndi nkhani za boma. Gary Wentz, watero. ULA.
Malinga ndi tsamba lawebusayiti la Aerojet Rocketdyne, injini ya RL10C-1-1 imapanga mphamvu yowonjezera yolemera mapaundi pafupifupi 1,000 kuposa injini yakale ya RL10C-1 yomwe idagwiritsidwa ntchito pa roketi ya Atlas 5.
Ma injini opitilira 500 a RL10 akhala akugwiritsa ntchito ma roketi kuyambira m'ma 1960. Roketi ya Vulcan Centaur ya ULA idzagwiritsanso ntchito injini ya RL10C-1-1, komanso maulendo onse amtsogolo a Atlas 5 kupatulapo Boeing's Starliner crew capsule, yomwe imagwiritsa ntchito gawo lapadera la Centaur la mainjini awiri.
Chaka chatha, roketi yatsopano yolimba yomangidwa ndi Northrop Grumman idayambitsidwa koyamba paulendo wa Atlas 5. Chowonjezera chachikulu, chomangidwa ndi Northrop Grumman, chidzagwiritsidwa ntchito paulendo wa Vulcan komanso maulendo ambiri amtsogolo a Atlas 5.
Chowonjezera chatsopanochi chilowa m'malo mwa chowonjezera cha Aerojet Rocketdyne chomwe chakhala chikugwiritsidwa ntchito pa kutulutsidwa kwa Atlas 5 kuyambira 2003. Ma rocket motor olimba a Aerojet Rocketdyne apitiliza kuwombera ma rocket a Atlas 5 kuti anyamule maulendo oyendetsedwa ndi anthu kupita kumlengalenga, koma ntchito ya sabata ino inali ndege yomaliza ya Atlas 5 yankhondo pogwiritsa ntchito kapangidwe ka galimoto yakale yotulutsira. Galimoto yotulutsira ya Aerojet Rocketdyne ili ndi ziphaso zoyambitsa oyendetsa ndege.
Kampani ya ULA yaphatikiza ma avionics ndi ma guide system a ma rocket ake a Atlas 5 ndi Delta 4 kukhala kapangidwe kamodzi komwe kadzawulukanso pa Vulcan Centaur.
Mwezi wamawa, ULA ikukonzekera kuvumbulutsa makina omaliza ofanana ndi a Vulcan omwe adzawuluke koyamba pa Atlas 5: malo operekera katundu omwe ndi osavuta komanso otsika mtengo kupanga kuposa denga la Atlas 5 lomwe linalipo kale.
Chipilala cha payload cha mamita 5.4 m'mimba mwake chomwe chidzayambike mwezi wamawa pa STP-3 chikuwoneka chofanana ndi chomwe chinagwiritsidwa ntchito pa maroketi a Atlas 5 akale.
Koma chifanizirochi ndi chipatso cha mgwirizano watsopano wa mafakitale pakati pa ULA ndi kampani yaku Switzerland ya RUAG Space, yomwe kale idapanga zifaniziro zonse za Atlas 5's 5.4-meter fairings ku fakitale ku Switzerland. Chifaniziro chaching'ono cha Atlas 5 chomwe chimagwiritsidwa ntchito pa ntchito zina chimapangidwa ku fakitale ya ULA ku Harlingen, Texas.
Makampani a ULA ndi RUAG apanga mzere watsopano wopangira zinthu zonyamula katundu m'malo omwe alipo ku Atlas, Delta ndi Vulcan ku Alabama.
Mzere wopanga wa Alabama umagwiritsa ntchito njira yatsopano yomwe imapangitsa kuti njira zopangira fairing zikhale zosavuta. Malinga ndi ULA, njira yopanga "yosakhala autoclave" ingagwiritse ntchito uvuni kokha kuti ichotse fairing ya carbon fiber composite, kuchotsa autoclave yothamanga kwambiri, yomwe imachepetsa kukula kwa ziwalo zomwe zingalowe mkati.
Kusintha kumeneku kumalola kuti fairing ya katundu igawidwe m'magawo awiri m'malo mwa zidutswa 18 kapena kuposerapo. Izi zichepetsa chiwerengero cha zomangira, zochulukitsa komanso kuthekera kwa zolakwika, ULA idatero mu positi ya blog chaka chatha.
ULA ikunena kuti njira yatsopanoyi imapangitsa kuti kupanga fairing yonyamula katundu kukhale kofulumira komanso kotsika mtengo.
ULA ikukonzekera kuyendetsa maulendo ena 30 kapena kuposerapo a Atlas 5 asanayimitse roketiyo ndikusamutsidwira ku roketi ya Vulcan Centaur.
Mu Epulo, Amazon idagula ndege zisanu ndi zinayi za Atlas 5 kuti iyambe kutumiza ma satellites ku netiweki ya intaneti ya Kuiper ya kampaniyo. Mneneri wa US Space Force's Space and Missile Systems Center adati sabata yatha kuti maulendo ena asanu ndi limodzi achitetezo cha dziko adzafunika maroketi a Atlas 5 m'zaka zingapo zikubwerazi, osawerengera ntchito ya SBIRS GEO 5 yomwe idayambitsidwa Lachiwiri.
Chaka chatha, US Space Force idalengeza mapangano a madola mabiliyoni ambiri kuti apereke ndalama zofunika kwambiri pachitetezo cha dziko pa maroketi a ULA a Vulcan Centaur ndi magalimoto oyambitsa ndege a SpaceX a Falcon 9 ndi Falcon Heavy mpaka chaka cha 2027.
Lachinayi, Space News inanena kuti Space Force ndi ULA agwirizana kusamutsa ntchito yoyamba ya usilikali yomwe inaperekedwa ku roketi ya Vulcan Centaur kupita ku roketi ya Atlas 5. Ntchitoyi, yotchedwa USSF-51, ikuyembekezeka kuyambitsidwa mu 2022.
Oyendetsa chombo anayi omwe akukonzekera kuuluka mumlengalenga mu kapisozi ya SpaceX ya Crew Dragon "Resilience" adakwera chombo chawo ku Kennedy Space Center Lachinayi kuti akaphunzire za kutulutsidwa kwawo ku International Space Station Loweruka madzulo, pomwe atsogoleri a Utumiki akuyang'anira nyengo ndi momwe nyanja ikugwirira ntchito panthawi yokonzanso malo opitilira Nyanja ya Atlantic.
Mainjiniya a NASA Kennedy Space Center omwe adzayang'anira kuyambitsidwa kwa ma satellite asayansi ndi ma probe ozungulira mapulaneti adzakhala ndi udindo woonetsetsa kuti maulendo asanu ndi limodzi akuluakulu afika mumlengalenga mosamala mkati mwa miyezi yoposa isanu ndi umodzi chaka chino, kuyambira ndi kutulutsidwa kwatsopano kwa NOAA GOES - pa Marichi 1, S Weather Observatory ikukwera roketi ya Atlas 5.
Roketi yaku China idaponya ma satellite atatu oyesera ankhondo m'mlengalenga Lachisanu, ndipo iyi ndi seti yachiwiri yokhala ndi ma satellite atatu otere yomwe idayambitsidwa m'miyezi yosakwana iwiri.
