Ngo-11: 30 ngo-Okthoba 19, 2021, injini ye-rocket eqinile yaseChina enesilinganiso esiphakeme kunazo zonke emhlabeni, nesilinganiso esiphakeme kunazo zonke esinabantu, futhi uhlelo lokusebenza olunobunjiniyela luhlolwe ngempumelelo ku-X''AN, lumaka ukuthi umthamo oqinile oqinile we-china kufinyelelwe kakhulu. Ukuthuthuka kubaluleke kakhulu ekuthuthukiseni ukuthuthukiswa kobuchwepheshe bemoto enkulu nobunzima bokuqalisa ngokuzayo.
Ukuthuthukiswa okuphumelelayo kwama-rocket motors akugcini nje ngokufaka umsebenzi onzima nokuhlakanipha kososayensi abaningi, kepha futhi ngeke nenze ngaphandle kwemikhiqizo yezinto eziningi zamakhemikhali ezinjengemikhiqizo eminingi yeTungsten kanye neMolybdenum.
I-rocket moto eqinile iyimoto yamakhemikhali esebenzisa umfuculi oqinile. Ihlanganiswa ikakhulukazi igobolondo, okusanhlamvu, igumbi lokuhlanganisa, umhlangano we-nozzle, kanye nensiza yokulahla. Lapho umgali eshisiwe, igumbi lokuhlangana kufanele libekezelele izinga lokushisa eliphakeme lama-degree angama-3200 kanye nengcindezi ephezulu ye-2 × 10 ^ 7Bar. Uma kucatshangelwa ukuthi kungenye yezinto ze-spacecraft, kuyadingeka ukusebenzisa izimpukane eziphakeme eziphakeme izinga le-alloy eliphakeme njengenziwe nge-molybdenum-based alloy noma i-alloy ye-titanium.
I-Molybdenum-based AllOY engekho emthethweni eyakhiwa ngokungeza ezinye izinto ezinjengeTitanium, zirconium, hafnium, tungsten kanye nomhlaba ongavamile nge-molybdenum njenge-matrix. Inokumelana okuhle kakhulu kwezinga lokushisa, ukumelana kwengcindezelo ephezulu nokumelana nokugqwala, futhi kulula ukucubungula kunoTungsten. Isisindo sincane, ngakho-ke kufanelekile ukusetshenziswa egumbini lokuhlanza. Kodwa-ke, ukumelana kwamazinga okushisa okuphezulu nezinye izakhiwo zama-alloys asuselwa ku-molybderum ngokuvamile azilungile njenge-tungsten-based alloys. Ngakho-ke, ezinye izingxenye ze-rocket injini, ezinjengezimbi zempi kanye namashubhu wokulahla, kusadinga ukukhiqizwa ngezinto zokwenziwa ezisuselwa ku-tungsten.
I-Throat Lining iyinto ebonakalayo yokufaka umphimbo we-rocket motor nozzle eqinile. Ngenxa yendawo enzima yokusebenza, kufanele futhi ibe nezakhiwo ezifanayo ezintweni ezisetshenziswayo ze-Fuel Chamber kanye ne-Ignition Tube impahla. Kwenziwa ngokwejwayelekile impahla ye-Tungsten Copper Composite. I-Tungsten Copper Material iyinto yokugxuma yokugxuma okuzenzakalelayo yohlobo lwensimbi, olungavikela ngempumelelo izinguquko zevolumu kanye nezinguquko zokusebenza emazingeni okushisa aphezulu. Umgomo wokupholisa izithukuthuku lokuthi ithusi kwi-alloy lizovezwa futhi likhishwe ekushiseni okuphezulu, okuzobe seludonsa ukushisa okuningi futhi kunciphise izinga lokushisa elingaphezulu.
I-tube yokulahla ingesinye sezingxenye ezibalulekile zedivayisi yokulahla injini. Ngokuvamile ifakwe esihlahleni se-flamethrower, kepha idinga ukujula egumbini lokuhlanganisa. Ngakho-ke, izinto zayo ezazifundayo zidingeka ukuba zibe nokumelana kakhulu okuphezulu okuphezulu nokuphikiswa okuningana. Ama-alloys asuselwa kuTungsten anezakhiwo ezinhle kakhulu ezifana nephuzu eliphakeme elincibilikayo, amandla aphezulu, ukumelana nomthelela, kanye nenqubomgomo ephansi yokunwebeka, okwenza kube ngenye yezinto ezithandwayo zamashubhu wokulahla.
Kungabonakala ukuthi imboni ye-tungsten ne-molybdenum ibe nomthelela empumelelweni yokuhlolwa kwe-roled rocket enjini run! Ngokusho kweChinatungsten online, injini yalokhu kuhlola i-RUNT yakhiwa yi-Fourth Research Institute of China Aerospace Science and Technology Corporation. Inobubanzi bamamitha ayi-3.5 kanye nokudabuka kwamathani angama-500. Ngobuchwepheshe obuningi obuphambili obufana nama-nozzles, ukusebenza kwenjini sekufinyelele ezingeni eliholayo emhlabeni.
Kuyafaneleka ukusho ukuthi kulo nyaka yase-China kwenze ukwethulwa kwemishini emibili ye-spacecraft. Lokho wukuthi, ngo-9: 22 ngoJuni 17, 2021, i-Rocket ye-Mashi 2f Carriers ephethe iShenzhou 12 yasungulwa i-Spacecraft. UNie Haisheng, uLiu Bomyung, noLiu Bming bethulwa ngempumelelo. UTang Hongbo uthumele ama-Astronauts amathathu emkhathini; Ku-0: 23 ngo-Okthoba 16, 2021, i-Long Mashi 2 F yao 13 Carrier Rocket ephethe iShenzhou 13 I-Spacecraft ye-Shenzhou 13 yathunyelwa ngempumelelo iZhaii Zhigang, ne-Guangfu emkhathini. Ithunyelwe esikhaleni.
