Aerospace le ho fofa

Aluminium e nkuoa e le tšepe e lumellang batho ho fofa. E bobebe, e matla ebile ea tenyetseha, e e etsa thepa ea bohlokoa bakeng sa ho etsa lifofane tse boima ho feta moea. Ho na le lebaka leo ka lona aluminium e tsejoang e le "tšepe e nang le mapheo" lipakeng tse ling. Pakeng tsa 75 le 80 lekholong ea sefofane sa sejoale-joale se entsoe ka aluminium, mme haele hantle, aluminium e ile ea sebelisoa pele ho lifofane pele ho qaptjoa sefofane. Ke kamoo Count Ferdinand Zeppelin a entseng foreimi ea sekepe sa hae se tummeng sa lifofane ka aluminium. Tsoelo-pele e ralileng motheo oa lifofane tsa sejoale-joale e etsahetse ka 1903, ha bara ba Wright ba fofa Flyer-1 ea bona. Sefofane sa pele se laolehang se boima bo fetang ba moea. Enjine tsa likoloi tsa nako eo li ne li le boima haholo ho fana ka matla a lekaneng hore sefofane se ka tloha. Ka hona, enjene e khethehileng e ile ea hahuoa bakeng sa sefofane sa Flier-1, se neng se na le likarolo tse joalo ka silinda se entsoeng ka aluminium.

Sefofane sa pele se ileng sa nkela sebaka sa lehong butle-butle, aluminium, tšepe le lisebelisoa tse ling, le moqapi ea tummeng oa lifofane oa Jeremane Hugo Schwartz's Forty ka 1917. Fuselage ea pele ea tšepe ea lefatše e hahiloe ka aluminium e thata, alloyum alloy, koporo (4,5%), le magnesium (4.5%). (1.5%) le mankanese (0.5%). Motsoako ona o ikhethileng o ntlafalitsoe ka 1909 ke Alfred Wilm, ea fumaneng hore e ka "apara", ho bolelang hore e ba matla haholo kamora kalafo e telele ea mocheso.

Ho tloha ka nako eo, aluminium e se e le sesebelisoa sa bohlokoa sa tlhahiso bakeng sa indasteri ea lifofane. Sebopeho sa lits'epe tse kopantsoeng ka aluminium tse sebelisitsoeng lifofaneng li fetohile 'me lifofane li ntlafetse, empa sepheo sa mantlha sa baqapi ba lifofane se lula se ts'oana: ho aha sefofane se bobebe ka hohle kamoo ho ka khonehang, se nang le bokhoni bo phahameng ka ho fetisisa, se sebelisa mafura a manyane kamoo ho ka khonehang le ka mmele o sa sebeng. sefofane se bobebe ka hohle kamoo ho ka khonehang, se nang le boholo bo ka khonehang, se sebelisa mafura a manyane ka hohle kamoo ho ka khonehang ebile ha se mafome 'meleng. Ke aluminium e lumellang lienjineri tsa lifofane ho fihlela sepheo sena kaofela. Aluminium e sebelisoa hoo e batlang e le kae kapa kae lifofaneng tsa sejoale-joale: ka fuselage, trim, lipaneteng le mapolanka, litsing tse thibelang, mekotleng ea ho qeta metsi, libakeng tsa phepelo, liphaepheng tsa Refueling, mamating le fatše, ka liforeimi tsa litulo tsa mofofisi le bapalami, ka lipompong tsa peterole, tsamaisong ea haeteroliki, ka har'a litšiea tse kahare tsa ntlo, libering tsa Ball li sebelisoa ka lisebelisoa tsa mokhosi, li-turbine tsa enjene le libakeng tse ling tse ngata. Li-alloys tsa aluminium tse sebelisoang haholo bakeng sa lits'ebetso tsa sepakapaka ke li-2xххх3хххххххххххххххх. 2xxx lethathamo le khothalletsoa bakeng sa lits'epe tse kopantsoeng tsa 7xxx li sebelisetsoa likarolo tse laetsoeng haholo libakeng tse mocheso o tlase le bakeng sa lits'ebetso moo ho hlokahalang mehato e phahameng. Li-alloys tsa 3xxx, 5xxx le 6xxx li sebelisetsoa likarolo tse nang le mojaro o tlase, hape le lits'ebetso tsa haeteroliki, oli le khase. Lubrication le mafura. Motsoako o sebelisoang ka ho fetisisa ke 7075, o nang le aluminium, zinki, magnesium le koporo. Ke eona e matla ho feta lits'epe tsohle tsa aluminium le lira tsa eona tse loantšanang ntlheng ena, empa ke karolo ea boraro feela ea boima ba tšepe.

Lifofane li bokelletsoe ka maqephe a masesaane le likarolo tse ts'oeroeng hammoho le li-rivets. Palo ea li-rivets ka sefofaneng e ka fihla ho limilione. Mefuta e meng e sebelisa liphanele tse hatisitsoeng ho fapana le ho etsa lakane, 'me e ka fihlela meeli ea phanele e joalo haeba ho na le petso. Mohlala, mapheo a sefofane se seholo ka ho fetesisa sa thepa lefatšeng, An-124-100 Ruslan, a na le likarolo tse robeli tsa aluminium tse bophara ba limithara tse 9. E ka jara lithane tse ka bang 120 tsa thepa. Mapheo a etselitsoe hore a tsoele pele ho sebetsa esita le ka liphanele tse senyehileng. Kajeno, baqapi ba lifofane ba batla thepa e ncha e nang le melemo eohle ea aluminium empa e le bobebe. Mokhethoa oa bona ke carbon fiber. E na le likhoele tse lipakeng tsa li-microne tse 5 ho isa ho tse 15 bophara 'me e entsoe haholo ka liathomo tsa khabone. Sefofane sa pele se nang le fuselage se entsoeng ka thepa e kopaneng e ne e le Boeing 787 Dreamliner, e ileng ea fofa ka lekhetlo la pele ka 2011. lifofane tsa khoebo. Leha ho le joalo, lifofane tse ngata li bitsa chelete e ngata ho feta lifofane tsa aluminium. Ntle le moo, likarolo tsa khabone ka kakaretso ha li fane ka boemo bo hlokahalang ba polokeho.

Aluminium ha e ea ipaka e le ea bohlokoa indastering ea lifofane, empa hape le bakeng sa motsoako oa eona oa boima bo tlase le matla a maholo 'Mele o moholo oa satellite ea pele ea maiketsetso, e phatlalalitsoeng Soviet Union ka 1957, e entsoe ka alloyum alloy. ho 90% ea lits'epe tse kopantsoeng tsa aluminium ka likarolo tsa tsona. Li-alloys tsa aluminium li sebelisoa fuselage ea sekepe sa sepakapakeng, li fumaneha manong a telescopic a Hubble Space Telescope; litanka tsa haedrojene tse sebelisoang liroketeng li entsoe ka alloyum alloy, ntlha ea rokete e entsoe ka alloyum alloy, likarolo tsa koloi ea ho qala le seteishene sa orbital, le ho tlamella liphanele tsa letsatsi Cell - Lintho tsena kaofela li entsoe ka aluminium motsoako.

Le li-boosters tsa rocket tse matla li entsoe ka aluminium. Lisebelisoa tsena, tse sebelisitsoeng karolong ea pele ea ho fofa sebakeng, li na le phofo ea aluminium, li-oxidizers (joalo ka ammonium perchlorate) le li-binders. Mohlala, koloi e matla ka ho fetesisa ea lefatše, Saturn-5 (e ka tsamaisang lithane tse 140 tsa thepa ho e potoloha), nakong ea leeto la eona ho potoloha lithane tse 36 tsa phofo ea aluminium li chesitsoe.
