Wu Guanghui: C929 lub dav hlau nkag mus rau theem pib tsim, txo cov pa roj carbon emissions los ntawm 60%
Lub Kaum Hli 22, 25th Lub Rooj Sib Tham Txhua Xyoo ntawm Tuam Tshoj Association rau Kev Tshawb Fawb thiab Tshuab tau qhib hauv Hefei, Anhui. Nyob rau ntawm International Green Aviation Development Forum muaj nyob rau tib lub sijhawm, Wu Guanghui, tus tsim qauv ntawm COMAC C919 thiab tus kws tshaj lij ntawm Tuam Tshoj Academy ntawm Engineering, tau qhia kuv lub teb chaws thawj zaug tsim dav hlau loj. Cov txiaj ntsig tau zoo ntawm lub dav hlau C919 hauv kev lag luam ntsuab aviation, nrog rau lub tswv yim ntsuab tsim ntawm lub dav hlau C929 uas tab tom tsim ua ntej.
"Nyob ntawm tus qauv ARJ21-700, peb tau txuas ntxiv txo qhov hnyav ntau dua 600 kilograms. Tam sim no lub rooj sib zog hnyav tsuas yog 7 kilograms, thiab qhov nruab nrab thoob ntiaj teb yog 12-14 kilograms." Wu Guanghui tau qhia tias tag nrho cov pa roj carbon hneev taw ntawm ARJ21-700 Emissions tau raug txo los ntawm 5.9%. Nyob rau theem pib ntawm C919 tsim, Wu Guanghui thiab nws pab neeg tau npaj cov tswv yim tsim qauv ntawm kev txo qhov hnyav, txo qis, thiab txo qis, tau txais kev tsim qauv zoo tshaj plaws los txhim kho aerodynamic efficiency, dav siv cov khoom siv sib xyaw kom txo tau qhov hnyav ntawm lub fuselage, thiab yuav ib tiam tshiab ntawm aeroengines. "Nws tuaj yeem hais tau tias C919 yog lub ntiaj teb thawj lub dav hlau loj los koom nrog lub tswv yim ntawm kev txo qis emission rau hauv nws cov qauv tsim sab saum toj." Wu Guanghui hais.
Tus nqi qis tshav dav hlau Crossbar Teeb, Customized Medium Siv Hom A,
Tsis siv neeg lub teeb hom A lwm tus neeg, Hnub ci nruab nrab siv hom B lwm tus neeg.
Tam sim no, lub dav hlau C929 tau nkag mus rau theem pib tsim. Wu Guanghui tau qhia tias C929 siv lub tswv yim ntsuab tsim ntawm kev siv roj tsawg, tsis tshua muaj suab nrov thiab qis emissions, thiab yuav siv ntau txoj kev los txo cov pa roj carbon monoxide. Piv txwv li, kev siv dav dav modular avionics tshuab yog siv los txo qhov hnyav ntawm cov khoom siv hauv huab cua; advanced aerodynamic technologies xws li tiam tshiab supercritical tis thiab variable camber tis yog siv los txhim kho aerodynamic efficiency; tus nqi ntawm cov khoom sib xyaw ua ke tau nce mus rau ntau dua 50% txhawm rau txo qhov loj ntawm lub dav hlau. Tus qauv hnyav; siv high bypass piv, low-suab nrov turbofan xyaw thiab nws kim heev siv biofuels kom ua tau kom txo qis roj noj nyob rau hauv lub nkoj nkoj. "Piv nrog cov qauv qub qub, C919 tuaj yeem txo cov pa roj carbon emissions los ntawm 12%-15%, thaum C929 teeb tsa lub hom phiaj siab dua los txo cov pa roj carbon emissions los ntawm 60%.
