Thaum 11:30 Lub Kaum Hli 19, 2021, Tuam Tshoj tus kheej-tsim monolithic khoom foob pob ua ntxaij cav nrog lub ntiaj teb loj tshaj plaws thrust, siab tshaj plaws impulse-rau-mass ratio, thiab engineerable daim ntawv thov tau ua tiav kev sim hauv Xi'an, kos cim tias Tuam Tshoj lub peev xwm nqa tau. tau ua tiav lawm. Kev kho dua tshiab yog qhov tseem ceeb heev rau kev txhawb nqa kev loj hlob ntawm cov tsheb loj thiab hnyav tshaj tawm hauv lub neej yav tom ntej.
Kev vam meej ntawm cov khoom siv foob pob hluav taws tsis yog tsuas yog ua rau lub zog ua haujlwm thiab kev txawj ntse ntawm cov kws tshawb fawb suav tsis tau, tab sis kuj ua tsis tau yam tsis muaj kev koom tes ntawm ntau cov khoom siv tshuaj xws li tungsten thiab molybdenum khoom.
Lub tshuab foob pob hluav taws yog lub tshuab foob pob hluav taws uas siv cov khoom siv hluav taws xob. Nws yog tsuas yog tsim los ntawm lub plhaub, cov nplej, lub combustion chamber, lub nozzle sib dhos, thiab cov khoom siv hluav taws xob. Thaum cov hluav taws kub hnyiab, lub combustion chamber yuav tsum tiv taus qhov kub thiab txias ntawm li 3200 degrees thiab siab siab txog li 2 × 10^7bar. Xav tias nws yog ib qho ntawm cov khoom siv hauv lub dav hlau, nws yog ib qho tsim nyog yuav tsum tau siv cov khoom siv sib zog ua kom muaj zog siab kub-kub xws li Ua los ntawm molybdenum-based alloy lossis titanium-based alloy.
Molybdenum-raws li alloy yog ib qho tsis-ferrous alloy tsim los ntawm kev ntxiv lwm yam xws li titanium, zirconium, hafnium, tungsten thiab tsis tshua muaj ntiaj teb nrog molybdenum li matrix. Nws muaj qhov kub thiab txias ua haujlwm zoo, kev kub siab ua haujlwm thiab kev tiv thaiv corrosion, thiab yooj yim rau txheej txheem dua li tungsten. Qhov hnyav yog me me, yog li nws yog qhov tsim nyog rau kev siv hauv chav combustion. Txawm li cas los xij, qhov kub thiab txias tsis kam thiab lwm yam khoom ntawm molybdenum-based alloys feem ntau tsis zoo li tungsten-based alloys. Yog li ntawd, qee qhov ntawm lub tshuab foob pob hluav taws, xws li lub caj pas thiab cov hlua hluav taws xob, tseem yuav tsum tau ua nrog cov khoom siv hlau tungsten.
Lub caj pas hauv ob sab phlu yog cov khoom siv rau hauv caj pas ntawm cov khoom siv foob pob hluav taws lub cev muaj zog. Vim qhov chaw ua haujlwm hnyav, nws yuav tsum muaj cov khoom zoo sib xws rau cov khoom siv roj chamber thiab cov khoom siv hluav taws xob. Nws feem ntau yog ua los ntawm tungsten tooj liab cov khoom sib xyaw. Cov khoom siv tungsten tooj liab yog cov hws hws txias yam khoom siv hlau, uas tuaj yeem zam qhov ntim deformation thiab kev hloov pauv ntawm qhov kub thiab txias. Lub hauv paus ntsiab lus ntawm hws txias yog tias cov tooj liab hauv cov hlau yuav ua kua thiab evaporated ntawm qhov kub thiab txias, uas yuav nqus tau cov cua sov ntau thiab txo qhov kub ntawm cov khoom.
Lub ignition tube yog ib qho tseem ceeb ntawm lub cav ignition ntaus ntawv. Nws yog feem ntau ntsia nyob rau hauv lub muzzle ntawm lub flamethrower, tab sis yuav tsum tau mus tob rau hauv lub combustion chamber. Yog li ntawd, nws cov ntaub ntawv tsim nyog yuav tsum muaj qhov kub thiab txias tsis kam thiab ablation tsis kam. Tungsten-raws li alloys muaj cov khoom zoo xws li cov ntsiab lus melting siab, siab zog, cuam tshuam tsis kam, thiab qis ntim expansion coefficient, ua rau lawv yog ib qho ntawm cov khoom nyiam rau kev tsim cov ignition raj.
Nws tuaj yeem pom tau tias kev lag luam tungsten thiab molybdenum tau pab txhawb kom muaj kev vam meej ntawm cov khoom siv foob pob hluav taws lub cav ua haujlwm! Raws li Chinatungsten Online, lub cav rau qhov kev sim no tau tsim los ntawm Lub Tsev Haujlwm Tshawb Fawb Plaub ntawm Tuam Tshoj Aerospace Science thiab Technology Corporation. Nws muaj ib txoj kab uas hla ntawm 3.5 meters thiab ib tug thrust ntawm 500 tons. Nrog ib tug xov tooj ntawm advanced technologies xws li nozzles, tag nrho cov kev ua tau zoo ntawm lub cav tau mus txog lub ntiaj teb no tus thawj theem.
Nws yog tsim nyog hais tias lub xyoo no Tuam Tshoj tau ua ob tug manned spacecraft launches. Ntawd yog, thaum 9:22 ntawm Lub Rau Hli 17, 2021, Lub Peb Hlis Ntuj 2F lub foob pob hluav taws uas nqa lub Shenzhou 12 manned spacecraft tau pib. Nie Haisheng, Liu Boming, thiab Liu Boming tau ua tiav tiav. Tang Hongbo xa peb astronauts mus rau qhov chaw; Thaum 0:23 Lub Kaum Hli 16, 2021, Lub Peb Hlis Ntuj 2 F Yao 13 cov neeg nqa khoom foob pob hluav taws nqa lub dav hlau Shenzhou 13 tus neeg ua haujlwm tau tsim thiab ua tiav nqa Zhai Zhigang, Wang Yaping, thiab Ye Guangfu mus rau qhov chaw. Xa mus rau qhov chaw.
