Mu 2021, mliri watsopano wa korona ukadali waukulu, ndipo kukula kwachuma padziko lonse lapansi kuli kochepa kwambiri. Komabe, kachilombo ka korona katsopano sikangathe kuyimitsa mayendedwe asayansi ndiukadaulo. Zida zankhondo ndizofunika kwambiri komanso zamakono zamakono. Pansi pa kukhudzidwa kwa zosowa zachitukuko zosinthira zida, kupita patsogolo kwaukadaulo kwakadali kodabwitsa. M'zaka zitatu zapitazi, takhazikitsa motsatizana "Makhalidwe Achitukuko Chachikulu cha Zida Zankhondo Zakunja". Ndi mwadongosolo kusanja patsogolo umisiri m'munda wa zida zankhondo m'chaka chino, tasankha umisiri khumi ndi chikoka chachikulu, ndi kuweruza m'tsogolo chitukuko cha zinthu kumunda, kulimbikitsa owerenga ndi owerenga. Ofufuza asayansi, akupereka nsanja yokambirana. M’zaka zitatu zapitazi, ntchito imeneyi yakhala ndi mayankho abwino.

Mu 2021, chiwonjezeko cha chitukuko cha zipangizo zophatikizika chidzakhala champhamvu, ndipo adzachita bwino pakufufuza ntchito m'madera amlengalenga ndi zida; m'malo osiyanasiyana ogwiritsira ntchito, zida zatsopano monga kukana kwambiri kwa radiation ndi kukana kuvala zidzatuluka; 2nm process chips idzawunikira zamagetsi. Pamwamba pa chitukuko cha zidziwitso zogwirira ntchito, zida za bismuth zatsegula njira ya tchipisi ta 1nm. Kuphatikiza apo, kuyambitsidwa kwa ma aligorivimu atsopano kwathandiziranso kupezeka kwamitundu yosiyanasiyana yamitundu yosiyanasiyana komanso zida zapamwamba za entropy alloy zomwe zimadalira kapangidwe kazinthu.

 

 

Pa Januware 19, 2022, China Aviation Industry Development Research Center idapanga akatswiri ku Beijing kuti achite ntchito yosankha "Zomwe Zili Zazikulu Zankhondo Zakunja mu 2021". Kuchokera pazochitika zachitukuko za 158 m'magawo asanu, kuphatikizapo zitsulo zogwirira ntchito, zipangizo zamakono zophatikizika, zipangizo zapadera zogwirira ntchito, zipangizo zamagetsi zamagetsi, ndi zipangizo zofunika kwambiri, machitidwe khumi otsatirawa amasankhidwa kuti afotokozedwe ndi mabungwe opanga zisankho, magawo ofufuza asayansi ndi owerenga.

US Air Force idatsimikizira bwino mapiko osindikizira a 3D opitilira

Kupanga mwachangu komanso makonda otsika mtengo ndizofunikira pakukula kwazinthu zophatikizika za carbon fiber. Bungwe la US Air Force Research Laboratory limayang'ana kwambiri paukadaulo wosindikiza wa 3D wosalekeza, ndikuyembekeza kuti ikhoza kukhala njira yaukadaulo yosinthira njira zachikhalidwe zopangira zinthu, kuchepetsa mtengo ndi nthawi yotsogolera yamagulu ambiri. Mu Epulo 2021, US Continuous Composites idagwiritsa ntchito luso lake losindikizira la fiber 3D (CF3D) kuti lisindikize bwino misonkhano iwiri yautali wa 2.4-mita, 1.8 kilogalamu ya carbon fiber composite spar, ndikumaliza ku US Air Force Research Laboratory.

Mgwirizano wazaka ziwiri wa Wing Structure Design for Manufacturing (WiSDM). Zotsatira zoyeserera zokhazikika pamapiko omaliza a msonkhano, mapiko osonkhanitsidwa kwathunthu adakwezedwa mpaka 160% ya kuchuluka kwa malire apangidwe. Palibe muyeso kapena kuwonongeka kowoneka kwa ma spars osindikizidwa a CF3D omwe adapezeka. Carbon fiber spar yosindikizidwa idapeza gawo la fiber voliyumu ya 60% ndi pafupifupi 1% -2% voids.

 

 

Njira yatsopano yopangira izi imakhala ndi in-situ impregnation, kuphatikiza ndi kuchiritsa, zomwe zimachepetsa kwambiri ndalama ndi nthawi zotsogolera. Njira yodzichitira yokha imakhala ndi kudula ndi kubwezeretsanso kwa ply drop and variable part makulidwe mkati mwa dongosolo. Pulojekitiyi, yomwe imakulitsa ulusi wokhazikika, ndi nkhani yopambana pogwiritsa ntchito njira ya CF3D yokhazikika, yomwe imakhudzanso kupanga zida zodula zamlengalenga.
