Ka ọ dị ugbu a, ULA na-eji rọketi Atlas 5 ya arụ ọrụ iji nwalee ihe ndị dị na rọketi Vulcan Centaur dị ike karịa tupu ụgbọelu mbụ nke ụgbọ elu ọhụrụ ahụ amalite. Injin BE-4 ọhụrụ nke ụlọ ọrụ mbara igwe nke Jeff Bezos, Blue Origin, dị njikere ma na-aga n'ihu na nnwale mbụ nke Vulcan.
Onyeisi ọrụ ULA, John Albon, kwuru na mbido Mee na rọketi Vulcan mbụ kwesịrị ịdị njikere maka mwepụta ya tupu ngwụcha afọ a.
Mbugharị mbụ nke Vulcan nwere ike ime na ngwụcha afọ a ma ọ bụ na mbido 2022, ka Kọnịlọn Robert Bongiovi, onye isi nke Space and Missile Systems Center nke Space and Missile Systems Center kwuru na Wenezde.

Mwepụta nke satịlaịtị ndị agha US Atlas 5 na Tuzdee nwalere ụdị injin RL10 dị elu nke ga-efegharị na ọkwa elu nke roket Vulcan Centaur. Mwepụta Atlas 5 ọzọ na June ga-abụ rọketi mbụ ga-eji Vulcan. . Dị ka ihe mkpuchi ibu arọ emere na USA, ọ bụghị Switzerland.
Ron Fortson, onye nduzi na onye njikwa izugbe nke ọrụ mwepụta na ULA kwuru na owuwu na nnwale nke sistemụ mwepụta ọhụrụ maka rọketi Vulcan Centaur fọrọ nke nta ka ọ gwụchaa.
"Nke a ga-abụ ebe a ga-eji abụọ eme ihe," Fordson kwuru n'oge na-adịbeghị anya ka ọ na-edu ndị nta akụkọ na njem nlegharị anya nke Launch Pad 41 na Cape Canaveral Space Force Station. "Ọ dịghị onye mere nke a mbụ, n'eziokwu, na-ebido Atlas na ahịrị ngwaahịa Vulcan dị iche kpamkpam n'otu ikpo okwu ahụ."
Injin RD-180 nke rọketi Atlas 5 nke Russia na-agba na kerosene agwakọtara ya na oxygen mmiri mmiri. Injin BE-4 Vulcan abụọ nke ọkwa mbụ na-agba ọsọ na gas eke ma ọ bụ mmanụ methane, nke chọrọ ka ULA tinye tankị nchekwa ọhụrụ na Platform 41.
Tankị nchekwa methane atọ nke galọn 100,000 dị n'akụkụ ugwu nke Launch Pad 41. Ụlọ ọrụ ahụ, nke jikọrọ aka na Boeing na Lockheed Martin, kwalitekwara sistemụ mmiri na-amịkọrọ ụda nke pad mmalite, nke na-ebelata ụda siri ike nke pad mmalite. Mmalite rọketi.
E mezikwara ebe nchekwa hydrogen na oxygen mmiri mmiri dị na Launch Pad 41 iji mee ka o kwekọọ n'ọkwa elu Centaur buru ibu, nke ga-efegharị na roket Vulcan.
Ọkwa elu nke ụgbọ elu ọhụrụ nke Vulcan nke Centaur 5 nwere dayameta nke ụkwụ 17.7 (mita 5.4), nke karịrị okpukpu abụọ karịa nke Centaur 3 nke dị n'elu nke Atlas 5. Centaur 5 ga-eji injin RL10C-1-1 abụọ rụọ ọrụ, ọ bụghịkwa otu injin RL10 ejiri mee ihe na ọtụtụ Atlas 5, ọ ga-ebukwa mmanụ ọkụ okpukpu abụọ na ọkara karịa Centaur nke dị ugbu a.
Fordson kwuru na ULA emechaala nnwale nke tankị nchekwa methane ọhụrụ ma ziga mmiri mmiri cryogenic site na eriri ọkọnọ ala gaa ebe a na-ewepụta ya na Pad 41.
"Anyị jupụtara tankị ndị a iji mata ihe onwunwe ha," Fordson kwuru. "Anyị nwere mmanụ ọkụ na-agafe ahịrị niile. Anyị na-akpọ nke a ule mmiri oyi. Anyị gafere ahịrị niile ruo na njikọ na VLP, nke bụ ikpo okwu mmalite Vulcan, yana rọketi Vulcan ewepụtara. vertex."
Ikpo Okwu Mmalite Vulcan bụ ihe ọhụrụ e ji ebupụ roket Vulcan Centaur site na ebe ULA jikọtara ọnụ ruo na Launch Pad 41. Na mbido afọ a, ndị ọrụ ala buliri isi ogbo Vulcan Pathfinder n'elu ikpo okwu ahụ wee tụgharịa roket ahụ n'elu ihe e ji ebupụ maka agba nke mbụ nke nnwale ala.
ULA na-echekwa VLP na Vulcan Pathfinder n'ebe a na-eme ihe ngosi na Cape Canaveral Space Operations Center dị nso ebe ụlọ ọrụ ahụ na-akwado rọketi Atlas 5 kachasị ọhụrụ ya maka ibuli elu site na iji satịlaịtị ịdọ aka ná ntị mbụ nke SBIRS GEO 5 nke ndị agha.
Mgbe e mechara mwepụta Atlas 5 na SBIRS GEO 5 nke ọma na Tuzdee, ndị otu Vulcan ga-ebugharị rọketi ahụ laghachi na Launch Pad 41 iji gaa n'ihu na-anwale Pathfinder. ULA ga-amalite itinye rọketi Atlas 5 n'ime VIF, nke a ga-ebido na June 23 maka ọrụ STP-3 nke Space Force.
ULA na-eme atụmatụ itinye mmanụ n'ụgbọala Vulcan maka oge mbụ, dabere na nnwale mbụ nke sistemụ ala.
"Oge ọzọ anyị wepụtara VLPs, anyị ga-amalite ime nnwale ndị a site na ụgbọala," ka Fortson kwuru.
Ụgbọala Vulcan Pathfinder rutere Cape Canaveral na Febụwarị n'ime roket ULA site na ụlọ ọrụ ụlọ ọrụ ahụ dị na Decatur, Alabama.
Mmalite nke Tuzdee bụ ọrụ mbụ nke Atlas 5 n'ime ihe karịrị ọnwa isii, mana ULA na-atụ anya na ọsọ ga-aka mma n'afọ a. Mgbe mmalite nke STP-3 nke June 23 gasịrị, a ga-eme atụmatụ maka mwepụta Atlas 5 ọzọ na Julaị 30, nke ga-agụnye nnwale nke modulu ndị ọrụ ụgbọ elu Starliner nke Boeing.
Fordson kwuru, sị, "Anyị kwesịrị ịrụcha ọrụ na Vulcan n'etiti mmalite ya." "Anyị ga-amalite STP-3 n'oge na-adịghị anya mgbe nke a gasịrị. Ha nwere obere windo iji rụọ ọrụ, nwalee ma nwalee ya, mgbe ahụ anyị ga-etinye ụgbọala ọzọ n'ebe ahụ."
Ọdụ ụgbọ elu Vulcan Pathfinder na-eji ebe a na-anwale injin BE-4 nke Blue Origin, nke na-enye ike maka rọketi a, nnwale nke tankị ya ga-enyere ndị injinia aka ịchọpụta otu esi etinye mmanụ n'ime Vulcan n'ụbọchị a ga-amalite ya.
"Anyị ga-aghọta ihe onwunwe niile na otu ha si arụ ọrụ ma zụlite CONOPS anyị (echiche nke ọrụ) site na ebe ahụ," ka Fordson kwuru.
ULA nwere ahụmịhe dị ukwuu na hydrogen mmiri mmiri oyi, mmanụ rọketi ọzọ a na-eji eme ihe n'ezinụlọ rọketi Delta 4 nke ụlọ ọrụ ahụ na ọkwa elu Centaur.
