Nenguva dza11:30 musi wa19 Gumiguru, 2021, injini yeroketi yakasimba yeChina yakagadzirwa yega ine simba guru pasi rose, chiyero chepamusoro cheimplism-to-mass, uye mashandisirwo ayo anogona kuitwa nemainjiniya yakaedzwa zvinobudirira muXi'an, zvichiratidza kuti kugona kweChina kutakura zvinhu zvakasimba kwave kuwanikwa zvakanyanya. Kuvandudzwa kwakakosha zvikuru mukusimudzira kuvandudzwa kwetekinoroji yemotokari hombe nedzinorema dzinotanga kuburitswa mune ramangwana.
Kubudirira kwekugadzirwa kwema rocket motors hakungoratidzi chete kushanda nesimba neuchenjeri hwemasayendisiti asingaverengeki, asiwo hazvigoneke pasina mipiro yezvinhu zvakawanda zvemakemikari zvakaita setungsten ne molybdenum.
Injini yeroketi yakasimba imota yeroketi yemakemikari inoshandisa solid propellant. Inonyanya kuumbwa negoko, tsanga, imba yekupisa, nozzle assembly, uye mudziyo wekupisa. Kana propellant yapiswa, imba yekupisa inofanira kutsungirira tembiricha yepamusoro inosvika 3200 degrees uye kumanikidzwa kwakanyanya kweinenge 2×10^7bar. Tichifunga kuti ndeimwe yezvikamu zvechikepe chendege, zvakakosha kushandisa zvinhu zvakareruka zvine simba repamusoro-soro zvakaita seYakagadzirwa nemolybdenum-based alloy kana titanium-based alloy.
Molybdenum-based alloy imhando isina ferrous alloy inoumbwa nekuwedzera zvimwe zvinhu zvakaita setitanium, zirconium, hafnium, tungsten uye rare earths ine molybdenum sematrix. Ine simba rakanaka rekudzivirira kupisa kwakanyanya, simba rekudzivirira kumanikidzwa kwakanyanya uye simba rekudzivirira ngura, uye iri nyore kugadzira kupfuura tungsten. Huremu hwayo hudiki, saka yakakodzera kushandiswa mukamuri yekupisa. Zvisinei, simba rekudzivirira kupisa kwakanyanya uye zvimwe zvinhu zvemolybdenum-based alloys hazviwanzo kuve zvakanaka setungsten-based alloys. Saka, zvimwe zvikamu zveinjini yeroketi, zvakaita sehuro nechubhu dzekubatidza, zvichiri kuda kugadzirwa nezvinhu zvetungsten-based alloy.
Huro ndiyo chinhu chinoiswa pahuro yeroketi yemota yakasimba. Nekuda kwenzvimbo yakaoma yekushanda, inofanirawo kunge iine hunhu hwakafanana nehwemukamuri yemafuta uye chinhu chinoiswa pachubhu yekupisa. Kazhinji inogadzirwa netungsten copper composite material. Tungsten copper material isimbi inotonhodza ziya, iyo inogona kudzivirira kushanduka kwehuwandu uye shanduko dzekushanda pakupisa kwakanyanya. Nheyo yekutonhodza ziya ndeyekuti mhangura iri mu alloy ichanyungudika uye kupwanyika pakupisa kwakanyanya, iyo inozotora kupisa kwakawanda uye kuderedza kupisa kwepamusoro pechinhu chacho.
Chubhu yekupisa ndeimwe yezvikamu zvakakosha zvechishandiso chekubatidza injini. Inowanzoiswa mumuromo wemuchina wekupfura moto, asi inofanira kupinda mukati mekamuri yekubatidza. Saka, zvinhu zvayo zvinodiwa kuti ive nekudzivirira kupisa kwakanyanya uye kudzivirira kudzima kwemhepo. Ma alloys akavakirwa paTungsten ane hunhu hwakanaka hwakadai sekunyunguduka kwakakwirira, simba rakawanda, kuramba kukanganiswa, uye kuwedzera kwehuwandu hwakaderera, zvichiita kuti ive imwe yezvinhu zvinofarirwa pakugadzira machubhu ekupisa.
Zvinogona kuonekwa kuti indasitiri ye tungsten ne molybdenum yakabatsira mukubudirira kwekuyedzwa kweinjini yeroketi yakasimba! Sekureva kweChinatungsten Online, injini yekuyedzwa uku yakagadzirwa neFourth Research Institute of China Aerospace Science and Technology Corporation. Ine dhayamita yemamita 3.5 uye simba rekukanda rinosvika matani 500. Neruzivo rwakati wandei rwepamusoro senge nozzles, kushanda kweinjini kwasvika padanho repamusoro pasi rose.
Zvakakosha kutaura kuti gore rino China yakaburitsa zvitundumusere zviviri zvine vanhu. Kureva kuti, nenguva dza9:22 musi wa17 Chikumi, 2021, roketi yeLong March 2F inotakura chitundumusere cheShenzhou 12 chine vanhu yakaburitswa. Nie Haisheng, Liu Boming, naLiu Boming vakaburitswa zvinobudirira. Tang Hongbo yakatumira vatyairi vezvitundumusere vatatu muchadenga; nenguva dza0:23 musi wa16 Gumiguru, 2021, roketi yeLong March 2 F Yao 13 inotakura chitundumusere cheShenzhou 13 chine vanhu yakaburitswa uye yakatakura Zhai Zhigang, Wang Yaping, naYe Guangfu muchadenga zvinobudirira. Yakatumirwa muchadenga.
