Thaum Lub Plaub Hlis 15, lub vev xaib raug cai ntawm Is Nrias teb lub chaw haujlwm hauv tebchaws, Indian Chaw Tshawb Fawb Chaw Tshawb Fawb (ISRO), tshaj tawm qhov kev ua tiav tshiab hauv lub tshuab foob pob hluav taws xob, nrog ISRO tau ua tiav kev txhim kho lub teeb yuag Carbon Fiber Reinforced Carbon Composite (Carbon-Carbon / CC) Nozzle. .
Qhov kev tsim kho thev naus laus zis no ua los ntawm Vikram Sarabhai Space Center (VSSC) yuav tsum ua kom lub peev xwm ntawm lub tsheb tso tawm los ntawm kev txhim kho qhov tseem ceeb ntawm lub tshuab foob pob hluav taws nrog rau qib thrust, tshwj xeeb impulse thiab thrust-rau-qhov hnyav piv.
VSSC txuas ntxiv nthuav dav nws txoj haujlwm pioneering hauv qhov chaw tshawb fawb los ntawm kev siv cov ntaub ntawv zoo xws li carbon-carbon (CC) composites los tsim lub nozzle disperser nrog cov khoom tshwj xeeb. Los ntawm kev siv cov txheej txheem xws li carbonization, tshuaj vapor-theem infiltration thiab high-temperature kho ntawm ntsuab composites, nws tau tsim ib lub nozzle nrog tsawg ntom, siab tshwj xeeb lub zog thiab zoo heev txhav uas tuav zoo heev mechanical zog txawm nyob rau hauv high kub.
Ib qho tseem ceeb ntawm CC composite nozzle yog nws tshwj xeeb silicon carbide oxidation-resistant txheej, uas txuas nws cov kev pab cuam txwv nyob rau hauv oxidizing ib puag ncig. Qhov kev tsim kho tshiab no tsis yog tsuas yog txo cov kev ntxhov siab thermal, tab sis kuj txhim kho kev tiv thaiv corrosion, tso cai rau ncua kev khiav hauj lwm kub txwv nyob rau hauv ib puag ncig hnyav.
Lub peev xwm cuam tshuam ntawm qhov kev siv thev naus laus zis no yog qhov loj heev, tshwj xeeb tshaj yog rau Polar Satellite Launch Vehicle (PSLV), ISRO's workhorse launcher.The PS4 yog theem plaub ntawm PSLV, uas tam sim no siv los ntawm ntxaib cav nrog nozzles ua los ntawm Columbium alloy; Txawm li cas los xij, los ntawm kev hloov cov hlau nozzles nrog CC composite nozzles, qhov hnyav ntawm kwv yees li 67% tuaj yeem ua tiav. Qhov kev hloov pauv no yuav tsum ua kom muaj peev xwm them taus ntawm PSLV los ntawm 15 kilograms, qhov nce ntxiv rau qhov chaw tshaj tawm txoj moo zoo.
Qhov kev sim ua tiav ntawm CC composite nozzle yog qhov tseem ceeb tshiab hauv ISRO txoj kev tshawb fawb hauv cheeb tsam no.A 60- thib ob thermal test tau ua nyob rau hauv High-Altitude Test (HAT) teeb ntawm ISRO Propulsion Complex (IPRC) hauv Mahendragiri ntawm 19 Lub Peb Hlis 2024 kom paub meej tias qhov kev ua tau zoo thiab kho vajtse ncaj ncees ntawm lub kaw lus. Test (HAT) chav nyob ntawm ISRO Propulsion Complex (IPRC) hauv Mahendragiri, qhov twg 60- thib ob thermal test tau ua kom paub tseeb tias qhov kev ua tau zoo thiab kho vajtse ruaj khov ntawm lub kaw lus. Cov kev sim tom ntej, suav nrog 200- qhov ntsuas cua sov thib ob thaum lub Plaub Hlis 2, 2024, tau ua kom pom tseeb ntxiv ntawm lub tshuab ua haujlwm, nce mus txog qhov kub ntawm 1,216 K, raws li kev kwv yees.
Lub Chaw Liquid Propulsion Systems Center (LPSC) ntawm Valiamala tau koom nrog hauv kev tsim thiab ua qhov kev sim, thiab IPRC ntawm Mahendragiri tau muab cov ntsuas ntsuas thiab ua tiav cov kev xeem ntawm nws qhov chaw HAT.
Hais txog Indian Chaw Tshawb Fawb Lub Koom Haum ISRO
Lub Koom Haum Indian Chaw Tshawb Fawb (ISRO) yog Is Nrias teb lub chaw haujlwm hauv tebchaws, uas yog ib feem tseem ceeb ntawm Lub Tsev Haujlwm Saib Xyuas Chaw (DOS) ntawm tsoomfwv Is Nrias teb. Lub tuam tsev siv qhov kev pab cuam Indian chaw feem ntau los ntawm ntau lub chaw lossis cov chav nyob hauv ISRO.
ISRO, yav tas los hu ua Indian National Committee for Space Research (INCOSPAR), tau tsim los ntawm Tsoomfwv Is Nrias teb hauv xyoo 1962, thiab Indian Chaw Tshawb Fawb Lub Koom Haum (ISRO) tau tsim nyob rau lub Yim Hli 15, 1969, hloov INCOSPAR, ua si ntau dua. lub luag haujlwm hauv kev siv lub tshuab thev naus laus zis. Xyoo 1972, DOS tau tsim thiab ISRO tuaj nyob rau hauv DOS division.Lub hom phiaj tseem ceeb ntawm ISRO/DOS yog los tsim thiab siv qhov chaw siv tshuab kom tau raws li cov kev xav tau ntawm ntau haiv neeg.
ISRO yog lub tsev hauv paus hauv Bangalore thiab nws cov haujlwm tau nthuav dav thoob plaws ntau lub chaw thiab cov chaw. Lub tsheb tso tawm yog tsim nyob rau ntawm VikramSarabhai Space Center hauv Thiruvananthapuram; satellites yog tsim thiab tsim ntawm UR Rao Satellite Center (URSC) hauv Bangalore; Kev koom ua ke thiab xa tawm cov satellites thiab cov tsheb xa tawm tau ua tiav ntawm Satish Dhawan Space Center (SDSC) hauv Sriharikota; kev txhim kho cov theem ua kua, suav nrog cov theem cryogenic, yog ua tiav ntawm Liquid Propulsion System Center (LPSC) hauv Valliamala thiab Bangalore; cov sensors rau kev sib txuas lus thiab tej thaj chaw deb sensing satellites thiab cov kev siv ntawm qhov chaw technology yog nqa tawm nyob rau hauv lub Ahmedabad Txoj kev loj hlob ntawm cov kua theem (xws li cryogenic theem) yog nqa tawm nyob rau hauv lub Liquid Propulsion Systems Center (LPSC) ntawm Valliamala thiab Bangalore; sensors rau kev sib txuas lus thiab chaw taws teeb sensing satellites thiab cov kev siv ntawm qhov chaw technology yog tswj los ntawm qhov chaw Applications Center (SAC) ntawm Ahmedabad, thiab txais tos, ua thiab kev nthuav tawm cov ntaub ntawv los ntawm tej thaj chaw deb sensing satellites yog tswj los ntawm National Remote Sensing Center (NRSC) ntawm Hyderabad .
