Lub Cev Armor tuaj yeem tiv thaiv tag nrho lub cev?

Cov lus teb yog obviously tsis. Muaj tsuas yog ib hom ntawm lub cev armor nyob rau hauv lub ntiaj teb no uas tuaj yeem tiv thaiv tag nrho lub cev - lub tank.

 

Cov tub rog lub cev tsis tu ncua tsuas yog muaj cov phom phom ntxiv rau thaj tsam hauv siab thiab plab, zoo ib yam li "lub plawv tiv thaiv" ntawm cov cuab yeej sib ntaus sib tua thaum ub, los tiv thaiv thaj chaw tseem ceeb.

 

Lub taub hau, caj dab, caj npab, lub xub pwg nyom, thiab puab tais tsis tuaj yeem tiv thaiv lub cev armor. Hauv qee qhov xwm txheej tshwj xeeb, xws li thaum cov tub rog tsis tas yuav khiav lossis txav mus sai thiab tsis tas yuav nqa cov khoom siv ntau, siv cov phom phom ntau dua - ib qho uas suav nrog sab vaj huam sib luag, tiv thaiv caj dab, thiab ncej puab armor. Txawm li cas los xij, xws li ib tug tub rog cumbersome yuav tsis muaj txiaj ntsig ntawm kev sib ntaus sib tua thiab tsuas yog tuag sai dua. Yog li, hom kev tiv thaiv no feem ntau tsuas yog tsim nyog rau cov neeg ua haujlwm koom nrog hauv kev tiv thaiv cov khoom tawg.

Txawm tias lub cev armor nrog tsuas yog pem hauv ntej thiab nraub qaum daim hlau tau ua rau muaj kev tsis sib haum xeeb hauv ntau yam tub rog. Qhov hnyav ntawm lub tsho tiv thaiv mos txwv tsis yog tsuas yog ua rau cov tub rog txoj kev txav mus los thiab ua rau kom qaug zog tab sis kuj cuam tshuam rau lawv cov tshuaj tiv thaiv lub sijhawm rau kev tua.

 

Hauv kev sib ntaus sib tua ntawm Iraq thiab Afghanistan, qhov hnyav nruab nrab ntawm cov tub rog Asmeskas yog 53 kilograms ib tus neeg. Nyob nruab nrab ntawm xyoo 2004 thiab 2007, ib feem peb ntawm cov tub rog uas tawm hauv tshav rog raug kev raug mob rau lawv cov txha nraub qaum, cov leeg nqaij, lossis cov pob txha pob txha, uas yog ob npaug ntawm qhov kev sib ntaus sib tua ncaj qha.

Yog li, txawm tias tsuas yog pem hauv ntej thiab sab nraub qaum daim phiaj phom phom (qhov hnyav ze li 6 kilograms), nws tseem ua rau lub nra hnyav rau cov tub rog. Qee lub sij hawm, tsuas yog ntxig ib lub phaj rau pem hauv ntej yog ua tiav vim tias qhov tshwm sim ntawm kev txhaj tshuaj tom qab tsis yog siab.

Vim li cas hnav lub cev armor?

 

Feem ntau ua rau tuag ntawm kev sib ntaus sib tua yog ob zaug:

 

1. raug tua ntawm lub taub hau los yog raug ntaus los ntawm shrapnel los ntawm kev tawg.

2. Kev raug mob ntawm lub hauv siab thiab lub plab.

 

Ob qho no ua rau suav txog kwv yees li 80 feem pua ​​​​ntawm kev sib ntaus sib tua tuag. Kev raug mob rau cov ceg ceg feem ntau ua rau muaj kev tsis taus ntau dua li kev tuag tam sim.

 

Yog li ntawd, hnav lub kaus mom hlau thiab lub cev armor ntawm kev sib ntaus sib tua tuaj yeem txo cov neeg tuag.

 

Kuj tseem muaj cov neeg ua haujlwm tshwj xeeb uas yuav tsum tau hnav khaub ncaws hnav, xws li cov neeg saib xyuas kev nyab xeeb thauj nyiaj los yog tub ceev xwm tub ceev xwm ua haujlwm tawm tsam kev ua phem. Lawv feem ntau ntsib phom phom los ntawm cov neeg phem.

 

Snipers feem ntau tsom rau lub plawv, thaum rab phom xws li phom yog feem ntau tsom rau ntawm lub hauv siab thiab lub plab nyob ze. Yog li ntawd, hnav lub cev armor tuaj yeem tiv thaiv ib feem tseem ceeb ntawm kev raug mob phom.

Cov neeg zoo tib yam, tshwj tsis yog lawv yog cov tib neeg tseem ceeb, tsis zoo li yuav raug tsom los ntawm snipers. Txawm li cas los xij, muaj kev zam rau qhov no.

 

Thaum muaj kev kub ntxhov hauv Balkan Peninsula, Sarajevo tau raug kaw los ntawm Yugoslav Tib Neeg Tub Rog thiab Bosnian Serb Army txij lub Plaub Hlis 5, 1992, txog rau Lub Ob Hlis 29, 1996. Peb lub xyoos no, muaj cov tub rog Serbian snipers nyob ib puag ncig thaj chaw siab thiab hauv cov tsev uas tso tseg, ua rau ntau tus pej xeem raug tua thaum taug kev ntawm txoj kev. Yog tias lawv tau hnav lub tsho tiv thaiv mos txwv hauv qab lawv lub tsho, lawv tuaj yeem zam kev puas tsuaj.

 

Hauv Bosnian Tsov Rog, ntau yam riam phom tau xaus rau hauv tes ntawm cov pej xeem. Nyob rau hauv ib puag ncig zoo li no, qhov chaw phom sij tshwm sim vim muaj kev tawm tsam rau zaub mov thiab ntau yam khoom, txawm tias cov pej xeem zoo tib yam yuav tsum xav txog kev muab lawv tus kheej nrog cov khaub ncaws mos mos.

Cov ntaub ntawv dab tsi yog siv rau cov tsho tiv thaiv mos txwv?

 

Bulletproof vests tuaj yeem muab faib ua hom mos thiab tawv. Cov tsho tiv thaiv mos mos feem ntau yog ua los ntawm ntau txheej txheej tshwj xeeb woven Kevlar thiab PE fiber ntau. Cov tsho tiv no tuaj yeem tiv thaiv kev nkag mus los ntawm cov phom phom thiab muab qhov haum zoo, tab sis lawv tsis muaj kev tiv thaiv txaus tiv thaiv cov mos txwv muaj zog dua.

 

Tsis tas li ntawd, cov fibers nyob rau hauv mos mos mos mos tsho khuam yuav degrade nyob rau lub sij hawm vim raug tshav ntuj thiab hws, ua rau lawv muaj kev laus. Nyob rau hauv cov nqe lus ntawm tus nqi-zoo, mos txwv daim hlau yog kom meej meej ib tug zoo xaiv.

Cov tsho tiv thaiv phom tawv tawv muaj xws li ntxig ntau hom mos txwv daim hlau rau hauv lub tsho tiv thaiv mos txwv. Cov ntaub ntawv siv rau cov mos txwv daim hlau muaj xws li steel, Kevlar, PE, ceramic, thiab ceramic-PE composite.

Cov phom phom hlau hlau tsis tshua muaj nqi tab sis muaj qhov tsis zoo ntawm kev hnyav heev. Lawv feem ntau tsis siv nyob rau hauv kev sib ntaus sib tua, tab sis qee zaus tuaj yeem pom ntawm cov neeg ua haujlwm ruaj ntseg lossis cov tub ceev xwm pabcuam hauv cov tebchaws uas tsim kho tsawg.

Kevlar mos txwv daim hlau yog qhov ua tau zoo tshaj plaws ntawm cov ntaub ntawv polymer uas siv hauv cov tsho tiv thaiv mos txwv. Ib qho kev xaiv zoo dua rau Kevlar nyob rau xyoo tas los no yog ultra-siab molecular hnyav polyethylene (PE). Ordinary PE cov ntaub ntawv yog cov yas mos, tab sis thaum cov molecules ua raws li cov saw ntev, nws dhau los ua cov khoom muaj zog tshaj plaws. Lub hauv paus ntsiab lus no zoo ib yam li cov pa roj carbon molecules hauv graphite, uas zoo nkaus li mos, tuaj yeem ua cov ntaub ntawv muaj zog heev xws li carbon fibers, pob zeb diamond, thiab graphene thaum npaj kom raug.

Ntawm cov khoom siv phom phom tam sim no, PE yog qhov sib sib zog nqus. Txawm li cas los xij, qib kev tiv thaiv siab tshaj plaws uas PE tuaj yeem ua tiav yog Qib 4, uas yog txaus tiv thaiv phom, phom submachine sib sib zog nqus, thiab riam phom improvised siv los ntawm cov neeg ua phem, tab sis nws tsis tuaj yeem tiv thaiv phom thiab phom phom phom.

Cov ntaub ntawv ceramic feem ntau siv rau cov ntawv tsis muaj phom yog silicon carbide thiab aluminium oxide. Nyob rau hauv lawv cov high-purity hniav nyiaj hniav kub-qib cov ntaub ntawv, txhuas oxide hu ua sapphire (xiav) thiab ruby ​​(liab), thaum silicon carbide hu ua moissanite. Cov hmoov ntawm silicon carbide thiab aluminium oxide feem ntau yog siv rau hauv kev sib tsoo lub log thiab cov pob zeb ua kom zoo nkauj rau riam sharpening vim tias lawv tseem nyuaj dua li cov hlau hnyav tshaj plaws.

 

Raws li ib tus neeg siv zoo tib yam, nws yuav nyuaj rau kev nkag siab cov ntsiab lus ntawm cov qauv ntsuas uas tau teev tseg los ntawm Ministry of Public Security. Yog tias koj tab tom yuav lub tsho tiv thaiv mos txwv, ntawm no yog ob peb lub ntsiab lus tseem ceeb kom nkag siab:

 

- Qib 4 lub tsho tiv thaiv mos txwv tuaj yeem tiv taus ntau yam 7.62x17mm thiab 7.62x25mm cov mos txwv phom thiab cov mos txwv submachine phom.

- Qib 5 lub tsho tiv thaiv mos txwv tuaj yeem tiv taus cov mos txwv 7.62x39mm.

- Qib 6 lub tsho tiv thaiv mos txwv tuaj yeem tiv taus 7.62x54mm sniper phom loj.
