"Ikhadi le-Trump" ku-Aerospace Materials

Siyazi ukuthi ukwehlisa isisindo somkhumbi-mkhathi kungonga ezindlekweni zokuqalisa.Njengensimbi ekhanyayo ebalulekile, i-beryllium iminyene kakhulu kune-aluminium futhi inamandla kunensimbi.Ngakho-ke, i-beryllium iyinto ebaluleke kakhulu ye-aerospace.Ama-alloys e-beryllium-aluminium, anezinzuzo zakho kokubili i-beryllium ne-aluminium, asetshenziswa kabanzi njengezinto zokwakha ezimotweni zasemkhathini, njengamasathelayithi okwenziwa kanye nemikhumbi-mkhathi.Uhlaka oluyisisekelo, ikholomu yegxolo kanye ne-truss engashintshi u-Liang et al.

Ama-alloys aqukethe i-beryllium nawo ayizinto ezisezingeni eliphezulu zokwakha indiza, futhi i-beryllium ingatholakala ezingxenyeni ezibalulekile njengamaphini amaphini namabhokisi amaphiko.Kubikwa ukuthi endizeni enkulu yesimanje, izingxenye ezingaba ngu-1 000 zenziwe nge-beryllium alloy.
Embusweni wensimbi, i-beryllium inezinto ezinhle kakhulu zokushisa, futhi inezindawo ezinhle kakhulu ezifana nephuzu elincibilikayo eliphezulu, ukushisa okuqondile okuphezulu, ukuqhutshwa kwe-thermal okuphezulu kanye nezinga elifanele lokunwetshwa kokushisa.Uma i-beryllium isetshenziselwa ukwakha amadivaysi okubhuleka ezindizeni eziphakeme kakhulu, inezinto ezinhle kakhulu zokumunca ukushisa kanye nezindawo zokuqeda ukushisa.Ukusebenzisa iberyllium ukuze kwenziwe “amajakhethi angangeni ukushisa” eziphuphutheki zokwenziwa nemikhumbi-mkhathi kungaqinisekisa ukuthi izinga lawo lokushisa ngeke likhuphuke kakhulu lapho lidlula emkhathini, ngaleyo ndlela kuqinisekiswe ukuphepha kwemikhumbi-mkhathi.Ngesikhathi esifanayo, i-beryllium yensimbi iphinde ibe yinto ebalulekile ekwenzeni izinhlelo zokuzulazula ezingenasici, ezibaluleke kakhulu ekuthuthukiseni ukunemba kokuzulazula kwemicibisholo, izindiza, nemikhumbi-ngwenya.Ngenxa yokuthi i-beryllium inokukhanya okuhle kwe-infrared, iphinde isetshenziswe ezinhlelweni ze-space optical.
