Gushyira mu bikorwa intego ya titanium mu ndege

Umuvuduko windege zigezweho wageze inshuro zirenga 2.7 umuvuduko wijwi.Indege nkiyi yihuta cyane izatera indege kunyerera mukirere kandi bitange ubushyuhe bwinshi.Iyo umuvuduko windege ugeze inshuro 2,2 umuvuduko wijwi, aluminiyumu ntishobora kwihanganira.Ubushyuhe bwo hejuru bwihanganira titanium alloy bugomba gukoreshwa.Ibikurikira, Impuguke mu ishami ry’ikoranabuhanga rya RSM izagabana impanvu intego za titanium alloy intego ari ingenzi mu ndege!

Iyo imbaraga zijyanye nuburemere bwa aeroengine ziyongereye kuva kuri 4 kugeza kuri 6 kugeza 8 kugeza 10, naho ubushyuhe bwo gusohoka bwa compressor bwiyongera kuva kuri 200 bugera kuri 300 ℃ bugera kuri 500 kugeza kuri 600 ℃, disiki yumuvuduko ukabije wa disiki na blade byakozwe mbere. aluminium igomba gusimburwa na titanium.

Mu myaka yashize, abahanga bateye intambwe nshya mubushakashatsi bwimiterere ya titanium.Amavuta ya titanium yumwimerere agizwe na titanium, aluminium na vanadium afite ubushyuhe bwo hejuru bwakazi bwa 550 ℃ ~ 600 ℃, mugihe aliyumu ya aluminiyumu nshya (TiAl) ivanze ifite ubushyuhe ntarengwa bwo gukora bwa 1040 ℃.

Gukoresha titanium alloy aho gukoresha ibyuma bidafite ingese kugirango ukore disikuru yumuvuduko ukabije wa disiki na blade birashobora kugabanya uburemere bwimiterere.Ibicanwa birashobora kuzigama 4% kuri buri 10% kugabanya ibiro byindege.Kuri roketi, kugabanya 1kg birashobora kongera intera kuri 15km.

Birashobora kugaragara ko ibikoresho byo gutunganya titanium bizakoreshwa cyane mu ndege, kandi abakora inganda zikomeye za titanium bagomba kwitangira ubushakashatsi no guteza imbere no gukora ibinini byo mu rwego rwo hejuru bya titanium kugira ngo babone umwanya mu isoko rya titanium.
