Nui nā mea e noʻonoʻo ai i nā ʻāpana mīkini no nā noi aerospace, e like me ke ʻano o ka ʻāpana, ke kaumaha a me ka lōʻihi.E pili ana kēia mau mea i ka palekana a me ka hoʻokele waiwai o ka mokulele.ʻO nā mea i koho ʻia no ka hana ʻana i ka aerospace he alumini mau ke gula nui.I nā mokulele hou, akā naʻe, he 20 pakeneka wale nō o ka nui o ka hale.
Ma muli o ka piʻi nui ʻana o ka noi no nā mokulele māmā, ke hoʻohana nei ka hoʻohana ʻana i nā mea composite e like me ka carbon-reinforced polymers a me nā mea honeycomb e hoʻonui nei i ka ʻoihana aerospace hou.Ke hoʻomaka nei nā ʻoihana hana Aerospace e noiʻi i kahi ʻano ʻē aʻe i nā alumini alumini—he kila kila kila.Ke piʻi aʻe nei ka hapa o kēia kila kila i nā mea mokulele hou.E noʻonoʻo kākou i ka hoʻohana ʻana a me nā ʻokoʻa ma waena o nā alumini alumini a me nā kila kila i nā mokulele hou.
Ka hoʻohana ʻana i nā ʻāpana alumini alumini ma ke kahua aerospace
ʻO ka alumini ka mea metala māmā loa, ʻo ke kaumaha ma kahi o 2.7 g/cm3 (grams no cubic centimeter).ʻOiai ʻoi aku ka maʻalahi o ka aluminika a ʻoi aku ke kumukūʻai ma mua o ke kila kila, ʻaʻole ikaika ka alumini a kū i ka corrosion e like me ke kila kila, ʻaʻole ikaika a kūpaʻa ʻole e like me ke kila kila.ʻOi aku ke kila kila ma mua o ka alumini ma ke ʻano o ka ikaika.
ʻOiai ua emi ka hoʻohana ʻana i nā alumini alumini i nā ʻano he nui o ka hana aerospace, noho mau nā alumini alumini i kahi koʻikoʻi i ka hana mokulele hou, a no nā noi kikoʻī he nui, ʻo ka alumini ka mea ikaika a māmā.Ma muli o kona ductility kiʻekiʻe a me ka maʻalahi o ka mīkini, ʻoi aku ka liʻiliʻi o ka alumini ma mua o ka nui o nā mea composite a i ʻole titanium.Hiki iā ia ke hoʻonui hou i kona mau mea metala ma o ka hoʻohui ʻana me nā metala ʻē aʻe e like me ke keleawe, magnesium, manganese a me ka zinc a i ʻole ma ke anuanu a wela paha.
ʻO nā alumini alumini i hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana aerospace:
1. Aluminum huila 7075 (aluminika/zinc)
2. Aluminum alloy 7475-02 (aluminika / zinc / magnesium / silicon / chromium)
3. Aluminum huila 6061 (aluminika / magnesium / silikon)
ʻO 7075, kahi hui o ka alumini a me ka zinc, ʻo ia kekahi o nā mea hoʻohana maʻamau i nā noi aerospace, e hāʻawi ana i nā waiwai mechanical maikaʻi loa, ductility, ikaika a me ke kūpaʻa luhi.
ʻO 7475-02 kahi hui o ka alumini, zinc, silicon a me chromium, aʻo 6061 ka aluminika, magnesium a me ke silika.ʻO ke ʻano o ka alloy e koi ʻia ma muli o ka noi i manaʻo ʻia o ka terminal.ʻOiai ʻo ka nui o nā ʻāpana alumini alumini ma ka mokulele he mea hoʻonani, ma ke ʻano o ke kaumaha māmā a me ka rigidity, ʻo ka alumini alumini ka koho maikaʻi loa.
ʻO kahi alumini alumini maʻamau i hoʻohana ʻia i ka ʻoihana aerospace he alumini scandium.ʻO ka hoʻohui ʻana i ka scandium i ka alumini e hoʻonui i ka ikaika o ka metala a me ka pale wela.ʻO ka hoʻohana ʻana i ka alumini scandium e hoʻomaikaʻi i ka pono wahie.No ka mea he ʻokoʻa ia i nā mea denser e like me ke kila a me ka titanium, ke hoʻololi nei i kēia mau mea me ka scandium alumini māmā hiki ke mālama i ke kaumaha, a laila e hoʻomaikaʻi ai i ka pono wahie a me ka ikaika o ka rigidity o ka airframe.
Hoʻohana ʻana i nā ʻāpana kila kila ma ka aerospace
I ka ʻoihana aerospace, he mea kupanaha ka hoʻohana ʻana i ke kila kila ke hoʻohālikelike ʻia me ka alumini.Ma muli o ke kaumaha o ke kila kila, ua hoʻonui ʻia kona hoʻohana ʻana i nā noi aerospace ma mua o ka wā.
ʻO ke kila kila ʻole ka ʻohana o nā mea hao i loaʻa ma ka liʻiliʻi he 11% chromium, kahi hui e pale ai i ka hao mai ka ʻino a hāʻawi i ka pale wela.ʻO nā ʻano ʻano like ʻole o ke kila kila e komo pū nā mea nitrogen, aluminika, silika, sulfur, titanium, nickel, keleawe, selenium, niobium a me molybdenum.Nui nā ʻano kila kila, ʻoi aku ka nui ma mua o 150 mau kila kuhiliʻole, a ʻo ka mea maʻamau i hoʻohana ʻia ma kahi o hoʻokahi hapaʻumi o ka huina o nā kila kila.Hiki ke hana ʻia ke kila kila i ka pepa, ka pā, ka pā, ka uea a me ka paipu, i kūpono ia no nā ʻano hana like ʻole.
ʻElima mau pūʻulu nui o nā kila kila i hoʻokaʻawale ʻia e ko lākou ʻano aniani.ʻO kēia mau kila kila:
1. Austenitic kila kila
2. Ferritic kuhiliʻole kila
3. Ke kila kuhiliʻole Martensitic
4. Duplex kila kila
5. Ua hoʻopaʻakikī ʻia ke kila kuhili ʻole
E like me ka mea i ʻōlelo ʻia ma luna nei, ʻo ke kila kila he huila i hoʻohui ʻia o ke kila a me ka chromium.ʻO ka ikaika o ke kila kila e pili pono ana i ka maʻi chromium i loko o ka'āpana.ʻOi aku ka kiʻekiʻe o ka chromium content, ʻoi aku ka kiʻekiʻe o ka ikaika o ke kila.ʻO ke kūpaʻa kiʻekiʻe o ke kila kila i ka corrosion a me nā wela kiʻekiʻe e kūpono ia no nā ʻāpana aerospace, me nā mea hana, nā mea hoʻopaʻa a me nā mea hoʻokele pae.
Nā pōmaikaʻi o ka hoʻohana ʻana i ke kila kila no nā ʻāpana aerospace:
ʻOiai ʻoi aku ka ikaika ma mua o ka aluminika, ʻoi aku ka nui o ke kaumaha o ke kila kila.Akā i ka hoʻohālikelike ʻia me ka alumini, ʻelua mau pono koʻikoʻi nā ʻāpana kila kila:
1. He kiʻekiʻe ka pale ʻana i ke kila kila.
2. ʻOi aku ka ikaika o ke kila kila a ʻoi aku ka pale ʻana i ka ʻaʻahu.
ʻOi aku ka paʻakikī o ka hana ʻana i ka modulus shear a me ka helu heheʻe o ke kila kila ma mua o nā alumini alumini.
He mea koʻikoʻi kēia mau waiwai i nā ʻāpana aerospace, a noho nā ʻāpana kila stainless i kahi kūlana koʻikoʻi i nā noi aerospace.ʻO nā mea maikaʻi o ke kila kila e komo pū me ka wela maikaʻi a me ke ahi kū'ē,'ālohilohi, nani ke nānā aku.ʻO ke ʻano a me ka maikaʻi maʻemaʻe maikaʻi.He mea maʻalahi hoʻi ke kila kila.I ka wā e pono ai e welded, mīkini a ʻoki ʻia nā mea mokulele i nā kikoʻī kikoʻī, ʻoi aku ka maikaʻi o ka hana maikaʻi o nā mea kila kila.Loaʻa i kekahi mau mea kila kuhiliʻole ke kūpaʻa kiʻekiʻe loa, e pili pū ana i ka palekana o nā mokulele nui.a ʻo ka lōʻihi ka mea nui.
I ka hala ʻana o ka manawa, ua ʻano like ʻole ka ʻoihana aerospace, a ua kūkulu ʻia nā kaʻa aerospace hou me nā kino kila kila a i ʻole nā lewa.ʻOiai ʻoi aku ka nui o ke kumukūʻai, ʻoi aku ka ikaika o lākou ma mua o ka alumini, a me nā māka ʻokoʻa o ke kila kila ma muli o ke ʻano, hiki i ka hoʻohana ʻana i ke kila kila ke hāʻawi i kahi ratio ikaika-a-kaumaha.
