I-aluminiyam ye-alloy ye-rocket fuel tank
Izinto zokwakha zinxulumene ngokusondeleyo kuthotho lwemiba efana noyilo lwesakhiwo somzimba we-rocket, ukuvelisa kunye netekhnoloji yokulungisa, itekhnoloji yokulungiselela imathiriyeli, kunye noqoqosho, kwaye isitshixo ekumiseleni umgangatho wokuthatha i-rocket kunye nomthamo womthwalo wokuhlawula. Ngokwenkqubo yophuhliso lwenkqubo yezinto, inkqubo yophuhliso lwezixhobo ze-rocket fuel tank inokwahlulwa ibe zizizukulwana ezine. Isizukulwana sokuqala si-5-series aluminium alloys, oko kukuthi, i-Al-Mg alloys. I-alloys emele i-5A06 kunye ne-5A03 alloys. Zaye zasetyenziselwa ukuvelisa izakhiwo zetanki ye-rocket ye-rocket ye-P-2 ekupheleni kweminyaka yoo-1950 kwaye zisasetyenziswa nanamhlanje. I-5A06 alloys equkethe i-5.8% Mg ukuya kwi-6.8% Mg, i-5A03 yi-alloy ye-Al-Mg-Mn-Si. Isizukulwana sesibini yi-Al-Cu-based 2-series alloys. Amatanki okugcina e-China ye-Long March uchungechunge lweenqwelo zokusungula zenziwe nge-alloys ye-2A14, eyi-Al-Cu-Mg-Mn-Si ingxubevange. ukusuka kwi-1970 ukuya kuthi ga ngoku, iChina yaqala ukusebenzisa itanki yokugcina i-alloy ye-2219, eyi-Al-Cu-Mn-V-V-Zr-Ti ingxubevange, isetyenziswa ngokubanzi ekwenzeni iitanki zokugcinwa kwezithuthi ezahlukeneyo. Kwangaxeshanye, ikwasetyenziswa ngokubanzi kulwakhiwo lwezixhobo zokuqalisa iitanki zamafutha obushushu obuphantsi, eyi-alloy esebenza ngokugqwesileyo kobushushu obuphantsi kunye nokusebenza okubanzi.
I-aluminium alloy yesakhiwo se-cabin
Ukususela ekuphuhlisweni kwezithuthi zokuqalisa e-China kwi-1960s kude kube ngoku, i-alloys ye-aluminium yesakhiwo sekhabhinethi yeenqwelo zokuqalisa zilawulwa sisizukulwana sokuqala kunye ne-alloys yesizukulwana sesibini esimelwe yi-2A12 kunye ne-7A09, ngelixa amazwe angaphandle angena kwisizukulwana sesine. i-cabin structural aluminium alloys (7055 alloy kunye ne-7085 alloy), zisetyenziswa ngokubanzi ngenxa yeempawu zazo zamandla aphezulu, ubuthathaka obuphantsi bokucima kunye ne-notch sensitivity. I-7055 i-alloy ye-Al-Zn-Mg-Cu-Zr, kwaye i-7085 nayo i-alloy ye-Al-Zn-Mg-Cu-Zr, kodwa ukungcola kwayo kwe-Fe kunye ne-Si umxholo ophantsi kakhulu, kwaye umxholo we-Zn uphezulu kwi-7.0% ~8.0%. Isizukulwana sesithathu i-Al-Li alloys emelwe yi-2A97, 1460, njl.njl isetyenziswe kumashishini e-aerospace yangaphandle ngenxa yamandla abo aphezulu, i-modulus ephezulu, kunye nokuphakama okuphezulu.
I-particle-reinforced aluminium matrix composites ineenzuzo zemodulus ephezulu kunye namandla aphezulu, kwaye ingasetyenziselwa ukutshintsha i-alloys ye-7A09 ukwenza i-semi-monocoque cabin stringers. Iziko loPhando lweMetal, i-Chinese Academy yeSayensi, i-Harbin Institute of Technology, iYunivesithi yaseShanghai Jiaotong, njl.njl. baye benza umsebenzi omningi kuphando kunye nokulungiswa kwe-particle-reinforced aluminium matrix composites, kunye nempumelelo ephawulekayo.
Iialloys zeAl-Li ezisetyenziswa kwi-aerospace yangaphandle
Esona sicelo siphumeleleyo kwiimoto ze-aerospace zangaphandle yi-alloy ye-Weldalite Al-Li ephuhliswe yi-Constellium kunye ne-Quebec RDC, kuquka i-2195, i-2196, i-2098, i-2198, kunye ne-2050 Alloy. I-alloy ye-2195: I-Al-4.0Cu-1.0Li-0.4Mg-0.4Ag-0.1Zr, i-alloy yokuqala ye-Al-Li ukuba ithengise ngempumelelo ukuveliswa kweetanki zokugcina i-fuel ephantsi yokushisa ukuqaliswa kwe-rocket. I-alloy ye-2196: I-Al-2.8Cu-1.6Li-0.4Mg-0.4Ag-0.1Zr, uxinano oluphantsi, amandla aphezulu, ukuqina kwe-fracture ephezulu, eyaphuhliswa okokuqala kwiiprofayili zesakhelo se-solar ye-Hubble, ngoku isetyenziselwa ukukhupha iiprofayili zenqwelomoya. I-alloy ye-2098: I-Al-3.5 Cu-1.1Li-0.4Mg-0.4Ag-0.1Zr, eyaphuhliswa ekuqaleni ukuveliswa kwe-HSCT fuselage, ngenxa yamandla ayo aphezulu okudinwa, ngoku isetyenziswa kwi-F16 fighter fuselage kunye ne-spacecraft i-Falcon yokusungula itanki yamafutha. . I-alloy ye-2198: i-Al-3.2Cu-0.9Li-0.4Mg-0.4Ag-0.1Zr, esetyenziselwa ukuqengqeleka kwephepha leenqwelo-moya zorhwebo. I-alloy ye-2050: I-Al-3.5Cu-1.0Li-0.4Mg- 0.4Ag-0.4Mn-0.1Zr, isetyenziselwa ukuvelisa iipleyiti ezityebileyo ezithatha indawo ye-7050-T7451 ye-alloy alloy plates ukuveliswa kwezakhiwo zeenqwelo-moya zorhwebo okanye izixhobo zokusungula i-rocket. Xa kuthelekiswa ne-alloy ye-2195, umxholo we-Cu + Mn we-alloy ka-2050 uphantsi kakhulu ukunciphisa ukuvakalelwa kokucima kunye nokugcina iimpawu eziphezulu zomatshini weplate eshinyeneyo, amandla athile angama-4% aphezulu, imodyuli ethile yi-9% ephezulu, kunye nokuqina kwe-fracture kunyuswa ngoxinzelelo oluphezulu lwe-corrosion cracking resistance kunye nokudinwa okuphezulu ukumelana nokukhula, kunye nokuzinza okuphezulu kweqondo lokushisa.
Uphando lwaseTshayina malunga namakhonkco okubumba asetyenziswa kwizakhiwo ze-rocket
Isiseko sokwenziwa kwezithuthi saseTshayina sikuMmandla woPhuhliso lwezoQoqosho noBuchwepheshe baseTianjin. Iqulunqwe ngophando lwe-rocket kunye nommandla wemveliso, indawo yoshishino lwesicelo sobuchwephesha be-aerospace kunye nommandla oncedisayo. Idibanisa ukuveliswa kweengxenye ze-rocket, indibano yecandelo, uvavanyo lokugqibela lwendibano.
Itanki yokugcina i-rocket propellant yenziwe ngokudibanisa iisilinda ezinobude be-2m ukuya kwi-5m. Amatanki okugcina ayenziwe nge-aluminium alloy, ngoko ke kufuneka adibaniswe kwaye aqiniswe nge-aluminium alloy forging rings. Ukongeza, izihlanganisi, amakhonkco otshintsho, iifreyimu zenguqu kunye nezinye iinxalenye ze-spacecraft ezifana neenqwelo zokuqalisa kunye nezikhululo zasemkhathini nazo kufuneka zisebenzise amakhonkco okudibanisa, ngoko ke amakhonkco okubumba luhlobo olubaluleke kakhulu lokuqhagamshela kunye neendawo zesakhiwo. I-Aluminiyam yaseMzantsi-ntshona (iQela) Co., Ltd., iNortheast Light Alloy Co., Ltd., kunye neNorthwest Aluminium Co., Ltd. benze umsebenzi omningi kuphando kunye nophuhliso, ukuvelisa kunye nokucubungula amakhonkco okubumba.
Ngo-2007, iAluminiyam yaseMazantsi-ntshona yoyisa ubunzima bobugcisa obufana nokuphosa i-billet enkulu, ukuvuleka kwebhilethi, ukuqengqeleka kweringi, kunye noguquko olubandayo, yaze yaphuhlisa iringi yokubumba ialluminiyam enobubanzi obuyi-5m. Ubuchwephesha bokubumba obuphambili buzalise isithuba sasekhaya kwaye sisetyenziswe ngempumelelo kwiLong March-5B. Ngo-2015, iAluminiyam yaseMazantsi-ntshona iphuhlise i-alluminiyam yokuqala enkulu-enkulu enkulu iyonke yokubumba iringi enobubanzi obuyi-9m, ibeka irekhodi lehlabathi. Ngo-2016, i-Aluminiyam yaseMazantsi-ntshona yoyisa ngempumelelo inani letekhnoloji eziphambili ezinjengokuqulunqa kunye nonyango lobushushu, kwaye yaphuhlisa intsimbi enkulu ye-aluminium yealloy enobubanzi obuyi-10m, ebeka irekhodi yehlabathi elitsha kwaye yasombulula ingxaki enkulu yobugcisa. kuphuhliso lwemoto yaseTshayina yosungulo olunzima.
