Ngo-2021, ubhubhani omtsha wethsaba usenobunzima, kwaye ukukhula koqoqosho lwehlabathi kunqongophele kakhulu.Nangona kunjalo, intsholongwane entsha yesithsaba ayinakumisa isantya senkqubela phambili yesayensi kunye nezobuchwepheshe.Izinto zomkhosi zezona zisisiseko kunye neteknoloji yokusika.Ngaphantsi kokutsalwa kweemfuno zophuhliso zokutshintshwa kwezixhobo, impumelelo ephambili yetekhnoloji isaphawuleka.Kule minyaka mithathu idlulileyo, siye sasungula ngokulandelelanayo "Iindlela zoPhuhliso eziNxibelelwano zeTekhnoloji yeMpahla yoMkhosi yaNgaphandle".Ngokucwangcisa ngokucwangcisiweyo inkqubela phambili yetekhnoloji kwicandelo lezinto zomkhosi kulo nyaka, sikhethe iitekhnoloji ezilishumi ezinempembelelo enkulu, kwaye sagweba ikamva lophuhliso lwenkalo yezixhobo, abafundi abakhuthazayo kunye nabafundi.Abaphandi beNzululwazi, ababonelela ngeqonga leengxoxo.Kule minyaka mithathu idlulileyo, lo msebenzi uye wafumana iimpendulo ezintle.
Kwi-2021, ukuqhubela phambili kokuphuhliswa kwezinto ezidibeneyo kuya kuba namandla, kwaye baya kwenza kakuhle ekuhlolisweni kwesicelo kwiinkalo ze-aerospace kunye nezixhobo;kwiindawo ezahlukeneyo zesicelo, izinto ezintsha ezifana nokuchasana kwe-radiation ephezulu kunye nokumelana nokunxiba kuya kuvela;Iichips zenkqubo ye-2nm ziya kukhanyisa i-elektroniki.Kwinqanaba eliphezulu lophuhliso lwezinto ezisebenzayo zolwazi, izinto ze-bismuth zivule indlela ye-chips ye-1nm yenkqubo.Ukongeza, ukungeniswa kwe-algorithms entsha kukwakhawulezisile ukufunyanwa kweekhompawundi ezahlukeneyo ze-inorganic kunye ne-high-entropy alloy materials ezixhomekeke kuyilo lwamacandelo.
NgoJanuwari 19, 2022, iZiko loPhando loPhuhliso lwezoPhando lwaseTshayina laququzelela iingcali eBeijing ukuba zenze umsebenzi wokukhetha "Iindlela eziMkhulu kwiZixhobo zoMkhosi zaNgaphandle kwi-2021".Ukusuka kwiindlela zophuhliso ezili-158 kwiinkalo ezintlanu, ezibandakanya izinto zetsimbi, izixhobo ezidityanisiweyo eziphambili, izixhobo ezikhethekileyo ezisebenzayo, ulwazi lwe-elektroniki, izinto ezisebenzayo, kunye nezixhobo eziphambili, ezi ndlela zilishumi zilandelayo zikhethwa ukuba zibhengezwe ngamaziko okwenza izigqibo, iiyunithi zophando lwenzululwazi kunye nabafundi.
I-US Air Force iqinisekise ngempumelelo i-fiber ye-3D yomshicileli wephiko spars
Ukuveliswa okukhawulezayo kunye neendleko eziphantsi zokuguquguquka ngokwezifiso ziyimfuneko ebalulekileyo yophuhliso lwangoku lwezixhobo ze-carbon fiber composite.I-US Air Force Research Laboratory igxile kakhulu kwiteknoloji yoshicilelo ye-fiber ye-3D eqhubekayo, ngethemba lokuba ingaba yindlela yobugcisa bempumelelo ekutshintsheni iindlela zemveli zokuvelisa, ukunciphisa iindleko kunye nexesha lokukhokela lamacandelo adibeneyo.Ngo-Epreli ka-2021, i-US Continuous Composites yasebenzisa i-patent yayo eqhubekayo ye-fiber 3D technology printing (CF3D) ukuprinta ngempumelelo ezimbini ii-2.4-meter-long, 1.8-kilogram carbon fiber composite spar assemblies, ukugqiba i-US Air Force Research Laboratory.
Ikhontrakthi yeminyaka emibini yeWing Structure Design for Manufacturing (WiSDM).Iziphumo zovavanyo lwe-Static kumphezulu wendibano yokugqibela yephiko, iphiko elihlanganiswe ngokupheleleyo lalayishwa ukuya kwi-160% yomthwalo womda wokuyila.Akukho mlinganiselo okanye umonakalo obonakalayo kwi-CF3D spars eprintiweyo efunyenweyo.I-carbon fiber spar eprintiweyo ifumene iqhezu le-fiber volume ye-60% malunga ne-1% -2% ye-voids.
Le ndlela intsha yokwenza izinto ezidityanisiweyo iquka ukumiliselwa kwe-in-situ, ukudibanisa kunye nokunyanga, okunciphisa kakhulu iindleko kunye namaxesha okukhokela.Inkqubo ezenzekelayo ngokupheleleyo ibonakalisa ukusika kunye nokubuyisela i-ply drop kunye nobukhulu benxalenye eguquguqukayo ngaphakathi kwesakhiwo.Iprojekthi, ekhulisa iintsinga zesakhiwo esiqhelanisiweyo, libali lempumelelo kusetyenziswa isisombululo semathiriyeli ye-CF3D, kunye neempembelelo zokwenziwa kweendawo ezixabisa kakhulu ze-aerospace.
