Aluminium alloy ye rocket fuel tank
Zvivako zvekugadzira zvine hukama zvakanyanya nenhevedzano yenyaya senge rocket body chimiro dhizaini, kugadzira uye kugadzirisa tekinoroji, tekinoroji yekugadzirira zvinhu, uye hupfumi, uye ndiyo kiyi yekuona kusimuka kweroketi uye kubhadhara kwemubhadharo. Zvinoenderana nekuvandudza maitiro eiyo zvinhu sisitimu, iyo yekuvandudza maitiro e rocket mafuta tank zvinhu inogona kukamurwa kuita zvizvarwa zvina. Chizvarwa chekutanga ndeye 5-series aluminium alloys, kureva, Al-Mg alloys. Mumiririri alloys ndeye 5A06 uye 5A03 alloys. Dzakashandiswa kugadzira P-2 rocket mafuta tank zvimiro mukupera kwema1950 uye zvichiri kushandiswa nhasi. 5A06 alloys ane 5.8% Mg kusvika 6.8% Mg, 5A03 is an Al-Mg-Mn-Si alloy. Chizvarwa chechipiri iAl-Cu-based 2-series alloys. Matangi ekuchengetedza eChina yeLong Kurume akatevedzana emotokari dzekutangisa anogadzirwa ne2A14 alloys, ari Al-Cu-Mg-Mn-Si alloy. kubva kuma1970 kusvika parizvino, China yakatanga kushandisa 2219 alloy kugadzira tangi yekuchengetera, inova Al-Cu-Mn-V-Zr-Ti alloy, inoshandiswa zvakanyanya mukugadzira akasiyana ekutanga matangi ekuchengetedza mota. Panguva imwecheteyo, inoshandiswa zvakanyanya mukugadzirwa kwechombo kuburitsa yakaderera-tembiricha mafuta matangi, iri alloy ine yakanakisa yakaderera tembiricha kuita uye yakazara kuita.
Aluminium alloy yekabhini chimiro
Kubva pakugadzirwa kwemotokari dzekutanga muChina muma1960 kusvika ikozvino, maaluminium alloys eiyo kabhini yekugadzira mota dzekutanga anotongwa nechizvarwa chekutanga uye yechipiri chizvarwa alloys inomiririrwa ne2A12 uye 7A09, nepo nyika dzekunze dzakapinda muchizvarwa chechina che cabin structural aluminium alloys (7055 alloy alloy alloy), 7055 alloy alloy alloy uye 7055 alloy alloy. yakaderera quenching sensitivity uye notch senitivity. 7055 iAl-Zn-Mg-Cu-Zr alloy, uye 7085 iri zvakare Al-Zn-Mg-Cu-Zr alloy, asi kusachena kwayo Fe neSi zvemukati kwakadzikira, uye Zn zvirimo zvakakwirira pa7.0% ~ 8.0%. Chizvarwa chechitatu cheAl-Li alloys anomiririrwa ne2A97, 1460, nezvimwewo zvakashandiswa mumaindasitiri ekunze emuchadenga nekuda kwesimba rawo repamusoro, modulus yakakwira, uye kureba kwepamusoro.
Particle-reinforced aluminium matrix composites ine zvakanakira high modulus uye yakakwirira simba, uye inogona kushandiswa kutsiva 7A09 alloys kugadzira semi-monocoque cabin stringers. The Institute of Metal Research, Chinese Academy of Sciences, Harbin Institute of Technology, Shanghai Jiaotong University, nezvimwewo vakaita basa rakawanda mukutsvagisa uye kugadzirira particle-yakasimbiswa aruminiyamu matrix composite, nekubudirira kunoshamisa.
Al-Li alloys anoshandiswa mune yekunze aerospace
Chishandiso chakabudirira kwazvo pamotokari dzekunze dzemuchadenga ndeye Weldalite Al-Li alloy yakagadziriswa neConstellium neQuebec RDC, inosanganisira 2195, 2196, 2098, 2198, uye 2050 Alloy. 2195 alloy: Al-4.0Cu-1.0Li-0.4Mg-0.4Ag-0.1Zr, inova yekutanga Al-Li alloy kuti ibudirire kutengeswa kwekugadzirwa kwemafuta ekudzikira-kupisa matangi ekutangisa maroketi. 2196 alloy: Al-2.8Cu-1.6Li-0.4Mg-0.4Ag-0.1Zr, low density, high-simba, high fracture toughness, yakatanga kugadzirirwa Hubble solar panel frame profiles, ikozvino inonyanya kushandiswa kuburitsa maprofile endege. 2098 alloy: Al-3.5 Cu-1.1Li-0.4Mg-0.4Ag-0.1Zr, yakatanga kugadzirirwa kugadzira HSCT fuselage, nekuda kwesimba rayo rekuneta, ikozvino inoshandiswa muF16 fighter fuselage uye spacecraft Falcon inotanga tangi yemafuta. 2198 alloy: Al-3.2Cu-0.9Li-0.4Mg-0.4Ag-0.1Zr, inoshandiswa kukungurutsa pepa rendege dzekutengesa. 2050 alloy: Al-3.5Cu-1.0Li-0.4Mg- 0.4Ag-0.4Mn-0.1Zr, yaishandiswa kugadzira mahwendefa akakora kutsiva 7050-T7451 alloy gobvu mahwendefa ekugadzira zvimiro zvendege dzekutengesa kana zvinhu zvekuvhura roketi. Kuenzaniswa neiyo 2195 alloy, iyo Cu + Mn ye2050 alloy yakadzikira kudzikisa kudzikamisa senitivity uye kuchengetedza yakakwira michina yeplate gobvu, iyo chaiyo simba iri 4% yakakwirira, iyo chaiyo modulus iri 9% yakakwirira, uye kuomarara kwekupwanya kunowedzera nekunyanya kushushikana kwecorrosion senge kusimba kwekurasa uye kusimba kwekupwanya.
Tsvagiridzo yeChina yekugadzira mhete dzinoshandiswa mumaroketi zvimiro
China yekutanga kugadzira mota base iri muTianjin Economic and Technological Development Zone. Iyo inoumbwa neroketi yekutsvagisa uye yekugadzira nzvimbo, aerospace tekinoroji application indasitiri nzvimbo uye yekubatsira inotsigira nzvimbo. Iyo inosanganisa roketi zvikamu kugadzirwa, chikamu musangano, yekupedzisira gungano kuyedzwa.
Rocket propellant storage tank inoumbwa nekubatanidza masilinda ane hurefu hwe 2m kusvika 5m. Matangi ekuchengetedza anogadzirwa nealuminium alloy, saka anoda kubatanidzwa uye kusimbiswa nealuminium alloy forging mhete. Pamusoro pezvo, zvinongedzo, zvindori zvekuchinja, mafaremu ekuchinja uye zvimwe zvikamu zvezvitundumuseremusere zvakaita semota dzekuvhura uye zviteshi zvemuchadenga zvinodawo kushandisa mhete dzekubatanidza, saka mhete dzekugadzira imhando yakakosha yekubatanidza uye zvimiro zvezvikamu. Southwest Aluminium (Group) Co., Ltd., Northeast Light Alloy Co., Ltd., uye Northwest Aluminium Co., Ltd. vakaita basa rakawanda mukutsvagisa nekusimudzira, kugadzira nekugadzirisa zvindori zvekugadzira.
Muna 2007, maodzanyemba akadziva kumadokero kweAluminium yakakunda matambudziko ehunyanzvi akadai sekukanda mahombe, kugadzira kuvhurika kwebillet, kutenderedza mhete, uye deformation inotonhora, uye yakagadzira mhete yealuminium alloy ine dhayamita ye5m. Iyo yekutanga yepakati yekugadzira tekinoroji yakazadza gap repamba uye yakabudirira kuiswa kune Yakareba Kurume-5B. Muna 2015, Southwest Aluminium yakagadzira yekutanga super-hombe aruminiyamu alloy yakazara forging mhete ine dhayamita 9m, ichiisa rekodhi pasi rose. Muna 2016, maodzanyemba akadziva kumadokero kweAluminiyamu yakabudirira kukunda akati wandei akakosha matekinoroji akadai sekuumburudza uye kurapwa kupisa, uye yakagadzira super-hombe aruminiyamu alloy forging mhete ine dhayamita gumi, iyo yakaseta rekodhi renyika uye kugadzirisa hombe hombe dambudziko rehunyanzvi pakuvandudza mota yeChina inorema-basa rekutanga.
