Ib qho kev tawg ntawm STEALTH thev naus laus zis tau tsim los ntawm cov kws tshawb fawb Lavxias. Cov neeg ua haujlwm ntawm National Research Technological University "MISiS" tau tsim cov khoom siv tshwj xeeb uas ua rau kev sib ntaus sib tua tsis pom nyob rau hauv ntau yam ntawm hluav taws xob hluav taws xob.
Ib txheej tshwj xeeb tuaj yeem hloov cov khoom ntawm lub teeb thiab hloov cov kev taw qhia ntawm electromagnetic tsis.
Siv:
Stealth tshuab
Stealth (English stealth, kuj stealth technology) yog ib txheej ntawm txoj kev los txo qhov pom ntawm kev sib ntaus sib tua tsheb nyob rau hauv radar, infrared thiab lwm qhov chaw ntawm lub detection spectrum los ntawm tshwj xeeb tsim geometric duab thiab siv xov tooj cua-absorbing cov ntaub ntawv thiab coatings, uas ho loj. txo qhov ntsuas hluav taws xob thiab yog li ua kom muaj sia nyob ntawm kev sib ntaus sib tua tsheb. Kev soj ntsuam txo cov thev naus laus zis yog ib qho kev ywj pheej ntawm tub rog kev qhuab qhia kev qhuab qhia ntawm hluav taws xob tiv thaiv, suav nrog ntau yam khoom siv thiab thev naus laus zis rau kev tsim cov khoom siv tub rog (aircraft, helicopters, nkoj, missiles, thiab lwm yam).
Nws yuav tsum raug sau tseg tias qhov tseem ceeb ntawm kev nqus ntawm cov xov tooj cua tsis tuaj yeem ua tiav tsuas yog nyob rau hauv qhov ntau centimeter, thiab ntau dua nyob rau hauv qhov ntau decimeter. Vim lub physics ntawm xov tooj cua yoj propagation, ua kom ib yam khoom NW nyuam qhuav pom nyob rau hauv lub 'meter' ntau yam, thaum lub wavelength yog piv rau cov khoom nws tus kheej qhov ntev, hloov nws cov duab yog, nyob rau hauv lub hauv paus ntsiab lus, yog tsis yooj yim sua. Tsis tas li ntawd, nyob rau theem tam sim no ntawm thev naus laus zis, nws tsis tuaj yeem ua tiav kev nqus ntawm txhua lub xov tooj cua emission poob ntawm ib qho khoom ntawm lub kaum ntse ntse. Hauv particular, los ntawm txoj kev stealth technologies, lub npe ua hauj lwm yog unsolvable ntawm tag nrho cov. Yog li ntawd, tam sim no, lub hom phiaj tseem ceeb thaum xaiv cov duab ntawm ib yam khoom (piv txwv li, lub dav hlau sib ntaus sib tua) yog qhov kev xav ntawm nthwv dej ntawm lub emitter - yog li, ib feem ntawm lub teeb liab yog absorbed los ntawm cov coatings tshwj xeeb, thiab tus so yog reflected. yog li ntawd lub xov tooj cua ncha tsis rov qab mus rau qhov kev soj ntsuam radar (uas yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov chaw nres tsheb transceiver ua ke).
Saib ntxiv:
Lavxias stealth
Nws yuav zoo li tias tam sim no, siv cov lej tau txais, nws yog qhov tsim nyog los pib tsim lub dav hlau stealth. Tab sis, ib qho kev tsis txaus siab tshwm sim - cov thawj coj tub rog ntawm peb lub teb chaws tau txiav txim siab tias "… kev tsim kho ntawm stealth aircraft raws li qhov kev xav no yog qhov tsis tsim nyog …". Ntxiv mus - "yog ib tug tuag-kawg ceg ntawm txoj kev loj hlob ntawm cov tub rog aviation …
Ib zaj duab xis hais txog yuav ua li cas ib tug Lavxias teb sab kws tshawb fawb tsim stealth technology, tsis pub leejtwg paub embodied los ntawm cov neeg Amelikas, thiab tom qab ntawd tsim ib tug technology rau ntes xws aircraft.
