Ku ya 19 Ukwakira 2021, saa tanu n'igice z'ijoro, moteri y'ubushinwa yo mu bwoko bwa monolithic solid rocket moteri ifite imbaraga nini ku isi, ingano nini cyane y'imbaraga, hamwe n'uburyo ikoreshwa mu buhanga yageragejwe neza i Xi'an, bigaragaza ko ubushobozi bw'ubushinwa bwo gutwara ibintu bikomeye bwagezweho cyane. Kuvugurura ni ingenzi cyane mu guteza imbere iterambere ry'ikoranabuhanga ry'imodoka nini n'iziremereye mu gihe kizaza.
Iterambere ryiza rya moteri zikomeye za roketi ntirigaragaza gusa umurimo ukomeye n'ubwenge bw'abahanga benshi, ahubwo rinashobora kubaho hatabayeho uruhare rw'ibikoresho byinshi bya shimi nka tungsten na molybdenum.
Moteri ya roketi ikomeye ni moteri ya roketi ikoresha icyuma gishyushya ibintu. Igizwe ahanini n'igikonoshwa, ingano, icyumba cyo gutwika, ihuriro ry'imizingo, n'igikoresho cyo gutwika. Iyo icyuma gishyushya ibintu gitwitswe, icyumba cyo gutwika kigomba kwihanganira ubushyuhe bwinshi bwa dogere 3200 n'umuvuduko mwinshi wa dogere 2 × 10 ^ 7. Bitewe nuko ari kimwe mu bigize icyogajuru, ni ngombwa gukoresha ibikoresho byoroheje kandi bishyushye cyane nka Aloi ishingiye kuri molybdenum cyangwa Aloi ishingiye kuri titanium.
Aloyi ishingiye kuri molybdenum ni aloyi idakoresha feri ikorwa no kongeramo ibindi bintu nka titaniyumu, zirconium, hafnium, tungsten na rare earths hamwe na molybdenum nk'umubumbe. Ifite ubushobozi bwo kurwanya ubushyuhe bwinshi, kurwanya umuvuduko mwinshi no kurwanya ingese, kandi yoroshye kuyitunganya kurusha tungsten. Uburemere bwayo ni buke, bityo ikaba ikwiriye gukoreshwa mu cyumba cyo gutwika. Ariko, ubushobozi bwo kurwanya ubushyuhe bwinshi n'ibindi bintu by'aloyi ishingiye kuri molybdenum akenshi ntabwo ari byiza nk'aloyi ishingiye kuri tungsten. Kubwibyo, bimwe mu bice bya moteri ya roketi, nk'imiyoboro y'umuhogo n'imiyoboro y'umuriro, biracyakeneye gukorwa hakoreshejwe ibikoresho by'aloyi ishingiye kuri tungsten.
Umwambaro wo mu muhogo ni wo ukoreshwa mu muhogo w'umunwa w'imodoka ikomeye ya roketi. Bitewe n'aho ikorera habi, igomba kandi kugira imiterere isa n'iy'ibikoresho byo mu cyumba cy'amavuta n'ibikoresho byo mu muyoboro w'umuriro. Muri rusange ikorwa mu bikoresho by'umuringa bya tungsten. Umwambaro wa tungsten ni icyuma gikonjesha ibyuya mu buryo bwihuse, gishobora kwirinda impinduka mu buryo bw'ingano no guhinduka k'imikorere mu bushyuhe bwinshi. Ihame ryo gukonjesha ibyuya ni uko umuringa uri mu cyuma uzashonga ugahinduka umwuka mu bushyuhe bwinshi, hanyuma bikagabanya ubushyuhe bwinshi ku buso bw'ibikoresho.
Umuyoboro w'amashanyarazi ni kimwe mu bice by'ingenzi by'igikoresho cyo gutwika moteri. Muri rusange ushyirwa mu munwa w'icyuma gitwika umuriro, ariko ugomba kwinjira cyane mu cyumba cyo gutwika. Kubwibyo, ibikoresho biwugize birakenewe kugira ngo bigire ubushobozi bwo kurwanya ubushyuhe bwinshi no kurwanya gutwika. Udupira dukozwe muri tungsten dufite imiterere myiza nko gushonga cyane, imbaraga nyinshi, kudakora neza, no kwaguka k'umuvuduko muto, bigatuma ari kimwe mu bikoresho bikunzwe cyane mu gukora imiyoboro y'amashanyarazi.
Bigaragara ko inganda za tungsten na molybdenum zagize uruhare mu gutuma igeragezwa rya moteri ikomeye ya roketi rigerwaho! Nk’uko Chinatungsten Online ibitangaza, moteri yo muri iki gikorwa cyo kugerageza yakozwe n’Ikigo cya Kane cy’Ubushakashatsi cya China Aerospace Science and Technology Corporation. Ifite umurambararo wa metero 3.5 n’umuvuduko wa toni 500. Hamwe n’ikoranabuhanga rigezweho nka nozzles, imikorere ya moteri muri rusange yageze ku rwego rwo hejuru ku isi.
Ni ngombwa kuvuga ko muri uyu mwaka Ubushinwa bwakoze ibyogajuru bibiri bifite abantu. Ni ukuvuga ko saa cyenda n'iminota makumyabiri n'ibiri ku ya 17 Kamena 2021, roketi ya Long March 2F yari itwaye icyogajuru cya Shenzhou 12 ifite abantu yaratangijwe. Nie Haisheng, Liu Boming, na Liu Boming baratangijwe neza. Tang Hongbo yohereje abahanga mu by'ikirere batatu mu kirere; saa 0:23 ku ya 16 Ukwakira 2021, roketi ya Long March 2 F Yao 13 yari itwaye icyogajuru cya Shenzhou 13 ifite abantu yaratangijwe neza, itwara Zhai Zhigang, Wang Yaping, na Ye Guangfu mu kirere neza. Yoherejwe mu kirere.
