Russia lub Titanium kev lag luam yog Enviable
Russia tus tshiab Tu-160M bomber tau ua nws lub dav hlau dav hlau thaum Lub Ib Hlis 12, 2022. Lub Tu-160 bomber yog ib tug sib txawv swept tis bomber thiab lub bomber loj tshaj plaws nyob rau hauv lub ntiaj teb no, nrog ib tug tag nrho loaded-off hnyav ntawm 270 tons.
Variable-sweep-wing aircraft yog tib lub dav hlau nyob hauv ntiaj teb uas tuaj yeem hloov lawv lub cev. Thaum lub tis qhib, qhov qis qis yog qhov zoo heev, uas yooj yim rau kev tawm mus thiab tsaws; Thaum cov tis raug kaw, qhov kev tiv thaiv me me, uas yooj yim rau kev ua haujlwm siab thiab siab ceev.
Qhib thiab kaw cov tis ntawm lub dav hlau yuav tsum muaj lub pob khawm txuas nrog lub hauv paus ntawm lub ntsiab tis. Lub pob khawm no tsuas yog ua haujlwm los tig tis, pab txhawb 0 rau aerodynamics, thiab them nyiaj ntau ntawm cov khoom hnyav.
Qhov ntawd yog tus nqi sib txawv-sweep-tis aircraft tau them.
Yog li ntawd, lub pob khawm no yuav tsum tau ua los ntawm cov khoom siv uas yog lub teeb thiab muaj zog, tsis yog hlau, lossis txhuas. Vim tias cov hlau hnyav dhau thiab txhuas tsis muaj zog, cov khoom siv zoo tshaj plaws yog titanium alloy.
Kev lag luam titanium alloy ntawm yav dhau los Soviet Union yog lub ntiaj teb kev lag luam, thiab cov thawj coj no tau txuas mus rau Russia, tau txais los ntawm Russia, thiab tau khaws cia.
Daim duab 160 tis cag titanium alloy pob khawm ntsuas 2.1 meters thiab yog qhov sib txawv loj tshaj plaws tis pob khawm hauv ntiaj teb.
Txuas nrog lub pob khawm titanium no yog lub fuselage titanium lub thawv girder nrog qhov ntev ntawm 12 meters, uas yog qhov ntev tshaj plaws hauv ntiaj teb.
70% ntawm cov khoom siv nyob rau hauv daim duab 160 fuselage yog titanium, thiab lub siab tshaj plaws overload yuav ncav cuag 5 G. Yog hais tias, cov qauv ntawm lub fuselage ntawm daim duab 160 muaj peev xwm dais tsib lub sij hawm nws tus kheej qhov hnyav tsis poob sib nrug, yog li theoretically, Qhov no 270-tuj foob pob tuaj yeem ua maneuvers zoo ib yam li cov dav hlau fighter.
Vim li cas Titanium thiaj li zoo?
Lub caij titanium tau pom thaum kawg ntawm lub xyoo pua 18th, tab sis nws tsuas yog xyoo 1910 uas cov kws tshawb fawb Asmeskas tau txais 10 grams ntawm titanium ntshiab los ntawm txoj kev txo sodium. Yog hais tias ib tug hlau yuav tsum tau txo los ntawm sodium, nws yog heev nquag. Peb feem ntau hais tias titanium yog corrosion-resistant heev, vim hais tias ib tug ntom hlau oxide tiv thaiv txheej yog tsim nyob rau saum npoo ntawm titanium.
Nyob rau hauv cov nqe lus ntawm txhua yam khoom, lub zog ntawm ntshiab titanium yog piv rau cov hlau zoo tib yam, tab sis nws qhov ceev tsuas yog me ntsis ntau tshaj li 1/2 ntawm cov hlau, thiab nws melting point thiab boiling point yog siab tshaj cov hlau, yog li titanium yog cov khoom siv hlau zoo heev.
