Ngentsasa ye-17, icandelo le-A-share ye-aviation iqhubekile nomkhwa wayo oqinileyo, kunye ne-Hangfa Technology kunye ne-Longxi Shares ezibetha umda wemihla ngemihla, kunye ne-Hangya Technology ekhuphuka ngaphezu kwe-10%. Ubushushu bekhonkco loshishino buqhubekile nokunyuka. Emva kolu tshintsho lwemarike, ingxelo yophando esandula ukukhutshwa yi-Tianfeng Securities ibe yeyona nto iphambili yokukhuthaza. Ingxelo yophando ibonisa ukuba ishishini leenqwelomoya zaseTshayina (COMAC) kunye neenjini zorhwebo (COMAC) zingenisa amathuba ophuhliso lwembali. Ngokoqikelelo, imfuno yeenjini ezintsha zorhwebo kwimarike yasekhaya ingadlula i-600 yeebhiliyoni zeedola zase-US ukusuka ngo-2023 ukuya ku-2042, kunye nobukhulu bemarike yonyaka obungaphezulu kwe-200 yeebhiliyoni zeeyuan.

Olu qikelelo lunxulumene ngokusondeleyo nesantya somthamo wemveliso kunye nenkqubo yonikezelo lwasekhaya lweenqwelomoya ezinkulu eziveliswe ekhaya i-C919 kunye ne-C929. Kuyafaneleka ukuba uqaphele ukuba ukongeza kumashishini okuvelisa i-aviation yendabuko, ababoneleli bezinto ezifana ne-titanium, i-aluminiyam, kunye nobhedu kwicandelo lesinyithi elingenawo i-ferrous nabo babonisa indlela esebenzayo. Ukukhawulezisa okuzimeleyo nokulawulwayo kwekhonkco loshishino lwezophapho lwentengiso, kudityaniswa ne-catalysis yemigaqo-nkqubo yezoqoqosho ekwindawo ephantsi, kubunjwa ngokutsha ixabiso lesicwangciso sezinto eziphambili zentsimbi ezinyukayo kwimarike.

I-Titanium alloy: umqolo wenqwelomoya enkulu yasekhaya

Njengesixhobo esilula esisisiseko sezixhobo zenqwelomoya, i-titanium alloy ithatha i-9.3% yesakhiwo somzimba we-C919, iphezulu kakhulu kune-Boeing 737. Ngokunyuka okukhawulezileyo komthamo wemveliso yenqwelomoya yasekhaya enkulu, imfuno yezixhobo ze-titanium kunye nomthamo omnye weyunithi malunga neetoni ze-3.92 ziya kunika ukunyuka kwemarike enkulu. I-Baotai Co., Ltd., njengomthengisi ongundoqo wezinto eziphathekayo ze-titanium, uye wabandakanyeka ngokunzulu kwimveliso yezinto eziphambili ezifana nezakhelo ze-fuselage kunye ne-injini ye-ring forgings. Itekhnoloji yecandelo loshicilelo lwe-3D ye-titanium alloy ephuhliswe yiWestern Superconductor inokunciphisa kakhulu ubunzima bezakhiwo kwaye ngokuthe ngcembe isetyenziswa ekuveliseni isizukulwana esitsha seenqwelomoya zasemoyeni ezingenabantu kunye ne-eVTOL (ukusuka kombane ngokuthe nkqo kunye nezithuthi zokumisa).

Aluminiyam ingxubevange: Injini ekhaphukhaphu yoqoqosho olunobude obuphantsi
Kwintsimi yoqoqosho oluphantsi, i-aluminium alloy ithatha isiqingatha sezinto zokwakha zenqwelomoya. Amandla aphezulu e-aluminium alloy akhawunti ngaphezu kwe-60% ye-fuselage kunye namacandelo ephiko abonelelwa yi-AVIC Xifei ye-C919. Iphepha le-aluminiyam yomgangatho wokubhabha ephuhliswe yiNanshan Aluminium Industry iye yaqinisekiswa yiCOMAC kwaye yasetyenziswa kwi-C919 fuselage skin, iphezulu kakhulu kuneprofayile zealuminiyam yemveli. Ngokoqikelelo, imfuno yonyaka ye-aluminiyam kwisixhobo sobude obuphantsi sase-China kulindeleke ukuba idlule iitoni ezingama-500000 ngo-2030, kunye ne-eVTOL zonke iifreyimu ze-aluminium fuselage kunye neemeko zebhetri ezikhaphukhaphu zibe zezona ndawo zikhulayo.

I-Copper zinc synergy: isiqinisekiso esiphindwe kabini sombane kunye ne-anti-corrosion
Ixabiso elifihliweyo lobhedu kwiinkqubo zombane ze-aviation ziyaqhubeka nokukhululwa. Kwiimveliso ezidityanisiweyo ze-AVIC Optoelectronics, i-akhawunti yobhedu olusulungekileyo oluphezulu lwe-70%, kwaye umgca wemveliso osanda kwakhiwa kwisiseko sawo saseLingang uya kuhlangabezana nemfuno ye-aviation grade copper alloys kunye nexabiso lemveliso yonyaka ye-3 yebhiliyoni ye-yuan. I-alloys esekelwe kwi-zinc ibonisa inzuzo yeendleko-zokusebenza kwi-aircraft anti-corrosion kunye nemveliso yecandelo. I-Hongdu Airlines isebenzisa iteknoloji ye-galvanizing ye-hot-dip ukunyanga amacandelo ezixhobo zokumisa, okwandisa ubomi bokuchasana nokubola ngokuphindwe kathathu kwaye kunciphisa iindleko nge-40% xa kuthelekiswa nezisombululo ezivela kumazwe angaphandle. Isicwangciso sendawo ye-zinc aluminium alloy aviation materials ephuhliswe ngu-Runbei Hangke uphumelele isiqinisekiso sokubonelela nge-COMAC.

Imingcipheko kunye namaThuba: Imingeni yoPhuculo lweShishini kwiCandelo leMpahla
Ngaphandle kwendawo enkulu yemarike, iibhotile zeteknoloji yezinto eziphezulu zisekho. Iqondo lobushushu obuphezulu be-Hangfa Technology kwi-injini yokwenziwa kweblade yi-65% kuphela, engaphantsi kunenqanaba lehlabathi. Kwinqanaba lomgaqo-nkqubo, iSicwangciso sokuPhunyezwa seZihlomelo eziNtsha zeZixhobo zeAviation Jikelele siphakamisa ngokucacileyo ukuphumeza umlinganiselo wendawo ongaphezu kwe-90% ye-aviation grade aluminium alloys kunye ne-titanium alloys ngo-2026, eya kubonelela ngefestile yokuphumelela kwezobuchwepheshe kumashishini afana ne-Baotai Group kunye ne-Western Superconductor. Ngokobalo lwamaziko, umndilili wokukhula komndilili wonyaka wokukhula kwemarike yezixhobo zentsimbi ezingeyontsimbi kule minyaka mithathu izayo iza kufikelela kuma-25%, kwaye amashishini anenkqubo epheleleyo yobuchule bempumelelo yeteknoloji kulindeleke ukuba axhamle kwisabelo sokubuyisela ekhaya kuqala.
