Na 11:30 muna Gumiguru 19, 2021, China yakazvigadzira yemonolithic yakasimba roketi injini ine hukuru hwepasirese, yepamusoro-soro-kusvika-hukuru reshiyo, uye injinjini yekushandisa yakaedzwa zvakabudirira muXi'an, zvichiratidza kuti China yakasimba-inotakura. yakawanwa zvikuru. Kukwidziridza kwakakosha zvikuru kusimudzira kuvandudzwa kwemahombe uye anorema ekutanga matekinoroji emotokari mune ramangwana.
Kubudirira kubudirira kwemaroketi akasimba haingomiriri kushanda nesimba uye huchenjeri hwemasayendisiti asingaverengeki, asi zvakare haigone kuita pasina mipiro yezvigadzirwa zvemakemikari akawanda senge tungsten uye molybdenum zvigadzirwa.
A solid rocket mota ikemikari roketi mota inoshandisa yakasimba propellant. Iyo inonyanya kuumbwa negoko, zviyo, kamuri yekupisa, musangano wenozzle, uye mudziyo wekupisa. Kana iyo propellant ichipiswa, kamuri rinopisa rinofanira kumira kutonhora kwakanyanya kweanenge 3200 madhigirii uye kudzvinyirira kwakanyanya kwe2 × 10 ^ 7bar. Tichifunga kuti chimwe chezvikamu zvechitundumuseremusere, zvinodikanwa kushandisa yakareruka-yakakwirira-yepamusoro-tembiricha alloy zvinhu zvakadai seMade of molybdenum-based alloy kana titanium-based alloy.
Molybdenum-based alloy is non-ferrous alloy inoumbwa nekuwedzera zvimwe zvinhu zvakaita setitanium, zirconium, hafnium, tungsten nemarare earths ane molybdenum sematrix. Iyo ine yakanakisa kupisa tembiricha kuramba, yakanyanya kumanikidza kuramba uye corrosion kuramba, uye iri nyore kugadzirisa pane tungsten. Huremu hudiki, saka inonyanya kukodzera kushandiswa mukamuri yekupisa. Nekudaro, iyo yakanyanya tembiricha kuramba uye zvimwe zvimiro zvemolybdenum-based alloys kazhinji hazvina kunaka senge tungsten-based alloys. Naizvozvo, zvimwe zvikamu zveinjini yeroketi, senge huro liners uye ignition chubhu, zvichiri kuda kugadzirwa ne tungsten-based alloy materials.
Hroat lining ndiyo yakavakirwa pahuro yerocket motor nozzle. Nekuda kwenzvimbo yekushanda yakaoma, inofanirwawo kunge iine zvimiro zvakafanana kune iyo mafuta kamuri zvinhu uye ignition chubhu zvinhu. Iyo inowanzo gadzirwa ne tungsten mhangura inoumbwa zvinhu. Tungsten mhangura zvinhu inongoerekana yayerera ziya inotonhora mhando yesimbi zvinhu, izvo zvinogona kudzivirira vhoriyamu deformation uye shanduko yekushanda pakupisa kwakanyanya. Nheyo yekutonhodza ziya nderekuti mhangura iri mualloy inonyungudutswa uye ichinyungudutswa pakupisa kwakanyanya, izvo zvinozotora kupisa kwakawanda uye kuderedza kupisa kwepasi kwechinhu.
Iyo ignition chubhu chimwe chezvakakosha zvikamu zveinjini yekubatidza mudziyo. Iyo inowanzo kuisirwa mumuromo weiyo flamethrower, asi inoda kupinda mukati memukati mekamuri yekupisa. Naizvozvo, ayo anoumba zvinhu zvinodiwa kuti ive yakanakisa yepamusoro tembiricha kuramba uye ablation kuramba. Tungsten-based alloys ane akanakisa zvimiro zvakaita senge yakakwira kunyungudika, simba rakawanda, kupikisa kwesimba, uye yakaderera vhoriyamu yekuwedzera coefficient, ichivaita chimwe chezvinhu zvinofarirwa zvekugadzira machubhu ekubatidza.
Zvinogona kuonekwa kuti tungsten uye molybdenum indasitiri yakabatsira mukubudirira kweiyo yakasimba roketi injini bvunzo kumhanya! Sekureva kwaChinatungsten Online, injini yeiyi bvunzo inomhanya yakagadziriswa nechina yeChina Research Institute yeChina Aerospace Science and Technology Corporation. Iyo ine dhayamita yemamita 3.5 uye kukwevera kwe500 matani. Nehuwandu hwetekinoroji yepamusoro senge nozzles, kuita kwese kweinjini kwasvika padanho rekutungamira pasirese.
Zvakakosha kutaura kuti gore rino China yakaburitsa zvitundumuseremusere zviviri zvine vanhu. Kureva kuti, na9:22 musi waChikumi 17, 2021, roketi rakareba Kurume 2F rakatakura Shenzhou 12 manned spacecraft rakatangwa. Nie Haisheng, Liu Boming, naLiu Boming vakatangwa zvinobudirira. Tang Hongbo akatumira vazivi vemuchadenga vatatu; na0:23 musi wa16 Gumiguru, 2021, dombo remutakuri raKurume 2 F Yao 13 rakatakura chitundumuseremusere cheShenzhou 13 rakaparurwa uye rakabudirira kutakura Zhai Zhigang, Wang Yaping, uye Ye Guangfu mudenga. Yakatumirwa muchadenga.
