Ku isaha ya saa 11h30, ku ya 19 Ukwakira 2021, Ubushinwa bwateje imbere moteri ya roketi ikomeye ya monolithic ifite moteri nini cyane ku isi, umubare munini w’abantu benshi, kandi ikoreshwa rya moteri ryageragejwe neza i Xi'an, byerekana ko Ubushinwa bufite imbaraga zikomeye zo gutwara byagezweho ku buryo bugaragara. Kuzamura bifite akamaro kanini mugutezimbere iterambere ryikoranabuhanga rinini kandi riremereye mugihe kizaza.
Iterambere ryiza rya moteri ikomeye ya roketi ntirigaragaza gusa akazi gakomeye nubwenge bwabahanga batabarika, ariko kandi ntishobora gukora hatabayeho umusanzu wibikoresho byinshi bya shimi nka tungsten na molybdenum.
Moteri ikomeye ya roketi ni moteri ya roketi yimiti ikoresha moteri ikomeye. Igizwe ahanini nigikonoshwa, ingano, icyumba cyaka, inteko ya nozzle, nigikoresho cyo gutwika. Iyo moteri yatwitse, urugereko rwaka rugomba kwihanganira ubushyuhe bwo hejuru bwa dogere 3200 hamwe numuvuduko mwinshi wa 2 × 10 ^ 7bar. Urebye ko ari kimwe mu bigize icyogajuru, ni ngombwa gukoresha ibikoresho byoroheje cyane-imbaraga zo mu rwego rwo hejuru ubushyuhe bwo mu rwego rwo hejuru nka Made ya molybdenum ishingiye ku mavuta cyangwa titanium.
Molybdenum ishingiye ku mavuta ni umusemburo utagira fer ukorwa wongeyeho ibindi bintu nka titanium, zirconium, hafnium, tungsten hamwe nubutaka budasanzwe hamwe na molybdenum nka matrix. Ifite ubushyuhe bwo hejuru cyane, irwanya umuvuduko mwinshi kandi irwanya ruswa, kandi byoroshye gutunganya kuruta tungsten. Uburemere ni buto, burakwiriye rero gukoreshwa mubyumba byaka. Nyamara, ubushyuhe bwo hejuru bwo guhangana nubundi buryo bwa molybdenum bushingiye ku mavuta ubusanzwe ntabwo ari bwiza nka tungsten ishingiye ku mavuta. Kubwibyo, ibice bimwe na bimwe bya moteri ya roketi, nk'umuhogo wo mu muhogo hamwe na tebes yo gutwika, biracyakenewe kubyazwa umusaruro wa tungsten.
Umuhogo wo mu muhogo ni ibikoresho byo mu muhogo wa moteri ikomeye ya roketi. Bitewe n’ibidukikije bikora, bigomba no kugira ibintu bisa nibikoresho bya peteroli hamwe nibikoresho byo gutwika. Mubisanzwe bikozwe mubikoresho bya tungsten. Umuringa wa Tungsten ni icyuma gikonjesha icyuma gikonjesha, gishobora kwirinda neza guhindura imiterere no guhindura imikorere mubushyuhe bwinshi. Ihame ryo gukonjesha ibyuya ni uko umuringa uri mu mavuta uza gutwarwa kandi ugahumeka ku bushyuhe bwinshi, bikazahita bikurura ubushyuhe bwinshi kandi bikagabanya ubushyuhe bw’ubutaka bwibintu.
Igikoresho cyo gutwika nikimwe mubice byingenzi byigikoresho cyo gutwika moteri. Mubisanzwe byashyizwe mumunwa wumuriro, ariko bigomba kwinjira cyane mubyumba byaka. Kubwibyo, ibikoresho byayo birasabwa kugira ubushyuhe buhanitse bwo guhangana nubushyuhe bwo hejuru. Amavuta ashingiye kuri Tungsten afite ibintu byiza cyane nko gushonga cyane, imbaraga nyinshi, kurwanya ingaruka, hamwe na coefficient yo kwaguka kwinshi, bigatuma iba kimwe mubikoresho byatoranijwe byo gukora imiyoboro yo gutwika.
Birashobora kugaragara ko inganda za tungsten na molybdenum zagize uruhare mugutsinda ikizamini cya moteri ikomeye ya roketi! Nk’uko Chinatungsten Online ibitangaza, moteri y’iki kizamini yakozwe n’ikigo cya kane cy’ubushakashatsi mu Bushinwa gishinzwe ubumenyi n’ikoranabuhanga mu kirere. Ifite umurambararo wa metero 3,5 hamwe na toni 500. Hamwe na tekinoroji igezweho nka nozzles, imikorere rusange ya moteri igeze kurwego rwo hejuru kwisi.
Twabibutsa ko muri uyu mwaka Ubushinwa bwakoze icyogajuru cy’abantu babiri. Ni ukuvuga, saa 9:22 ku ya 17 Kamena 2021, roketi ndende ya Werurwe 2F itwara icyogajuru cya Shenzhou 12 cyakozwe. Nie Haisheng, Liu Boming, na Liu Boming batangijwe neza. Tang Hongbo yohereje mu kirere batatu mu kirere; saa 0:23 ku ya 16 Ukwakira 2021, roketi ndende yo ku ya 2 Werurwe Ya Ya 13 yari itwaye icyogajuru cyitwa Shenzhou 13 cyakozwe mu kirere kandi itwara Zhai Zhigang, Wang Yaping, na Ye Guangfu mu kirere. Yoherejwe mu kirere.
