5. Mhedziso
Kuenzanisa kwe160 GSM, 200 GSM uye 400 GSMKevlarpasi pe ballistic maitiro akaitwa neiyo ballistic bvunzo dzakaitwa ne 9 mm Parabellum ammunition uye nenhamba dzakasiyana dzeKevlar layer.Izvo zvakaonekwa kuti mashoma mashoma eKevlar haashande mukumisa projectiles, asi kuti anomanikidza mapurojekiti kuti afambe mberi kupinda mu ballistic gel.Kamwe chete nhamba yezvikamu zvakawedzerwa, kuderera kweprojekiti yekupinda mu ballistic gel yakaonekwa.Chikonzero chepamusoro pekupinda uku, kunyanya nehollow point projectiles, yaive nekuda kwegomba kuzadza neKevlar zvinhu uye kuita kuti iite senge FMJ projectile.Avhareji akaenzana asina kunaka gradients akaonekwa pakati peFMJ uye hollow point projectiles, kana iyo yepamusoro yasvika.
Kupfupisa mipiro yepepa iri, inogona kugumiswa:
-
1)
-
Kubudirira kwezvikamu zvakasiyana zve160 GSM, 200 GSM uye 400 GSM mamakisi eKevlar akaturikidzwa nejeli reballistic akaongororwa, uye zvakaonekwa kuti mazana maviri GSM Kevlar ainyanya kushanda pakumisa 9 mm Parabellum projectile.
-
2)
-
Zvakaonekwa kuti hapana hukama hwemutsara pakati pemhando mbiri dzakasiyana dzeKevlar dzine uremu hwakasiyana (se200 GSM uye 400 GSM Kevlar), dzakaturikidzana nenzira yekuti dzine huremu hwakafanana hwakasanganiswa.

Yakaongororwa kuti kune 9 mm Parabellum ammunition, iyo inonyanya kushandiswa pasirese, 21 akaturikidzana e200 GSM Kevlar anodiwa sediki kumisa projectile.Zvinokurudzirwa kuti, sekuchengetedza kuchengetedza, imwezve yekuchengetedza chinhu inosanganisirwa sezvo kupinza kunoenderana zvakare neprojectile profile.
Zvichienderana nemhedzisiro yakapihwa pamusoro pehunhu hweKevlar layers ehuremu hwakasiyana, zvinotarisirwa kuti hunhu uhwu hunogona kushandiswa kugadzira nekugadzira mabhati akachengeteka uye anoshanda-bullet-proof.
Maitiro akajairwa akapetwa kaviri huwandu hwezvikamu zveKevlar zvinodikanwa kana zvichienzaniswa nehuwandu chaihwo hwezvikamu zvakakuvadzwa, zvingave zvakakosha kuongorora mune imwe tsvakiridzo nepfuti dzakasiyana.Tsvagiridzo yeramangwana yaizokwanisawo kuratidza maitiro ekupinda ayo madiki caliber projectiles uye zvombo zvine paKevlar mukuenzanisa neiyo ye9 mm Para ammunition.Saizvozvo, tsvakiridzo yeramangwana ichakwanisa kuona kuti mabara nemapurojekiti akasiyana sei 200 GSM Kevlar seKevlar inoshandiswa chete mumabhururu evhavha.Nehunhu hunocherechedzwa nehollow point projectiles inopinda zvakadzika mukati meiyo ballistic gel, mushure megomba ravharwa neKevlar, tsvakiridzo yeramangwana yaizobvumira kuona kana chiitiko chakafanana chingaitika mumamiriro ezvinhu apo projectile yakapinda zvipfeko, isati yapinda munyama. .
