Tom qab Kev Tsov Rog Thoob Ntiaj Teb Zaum Ob Kawg, muaj ntau tus riam phom thiab khoom siv tau poob rau hauv Soviet cov tub rog txhais tes. Los ntawm qee qhov ntawm lawv, USSR tab tom pib tsim nws tus kheej cov analogues. Yog li, tau ntes 75mm PaK 41 phom tiv thaiv lub tank txaus siab rau Soviet cov tub rog tshwj xeeb, ua ntej tshaj plaws, nrog nws cov thooj voos kheej kheej-conical lub tog raj kheej thiab cov cuab yeej nkag mus. Kev tsim kho cov riam phom Soviet zoo ib yam nrog lub peev xwm ntawm 76.2 / 57 mm tau pib ua los ntawm Central Artillery Design Bureau txij li xyoo 1946. Cov phom tiv thaiv lub tank hu ua S-40 thiab tau muab cais ua cov phom tiv thaiv lub tank.
Ntaus thiab tsim
Qhov qis (thauj khoom) rau rab phom tshiab raug coj los ntawm ZIS-S-8 phom tiv thaiv lub tank tsim xyoo 1944, muaj peev xwm 85 hli. Kev hloov me me tau ua rau lub tsheb thauj mus los. Lub thoob, vim nws lub ntsej muag lub ntsej muag, muaj 76.2 mm caliber hauv qhov ntau dua (breech) thiab 57 mm caliber hauv ntu me me (muzzle). Qhov ntev ntawm cov cylindrical-conical chim yog 5.4 meters. Lub chaw them nyiaj rau rab phom tshiab tau siv los ntawm rab phom tiv thaiv dav hlau 85 hli, qauv xyoo 1939. Tom qab lub chav, cov xov conical ib feem ntawm 76.2mm caliber nrog qhov ntev ntawm 3.2 meters pib. Nws muaj 32 rab phom ntev tsis tu ncua (22 ntsuas). Lub qhov ncauj tau txais lub taub hau nrog lub cylindrical-conical channel. Tshooj ntawm lub taub hau zoo li lub taub hau muaj qhov ntev ntawm 51 centimeters, ntu ntawm lub tog raj kheej kheej kheej yog 59 centimeters. Cov phom tau txais ib txoj kab ntsug ntsug breechblock thiab cov tshuab ua haujlwm tsis siv neeg luam ib hom. Aiming cov ces kaum - (-5 + 30) degrees ntsug, (± 25) degrees horizontally. S-40 tsis muaj rab phom pem hauv ntej; lub txaj tau siv rau kev thauj mus los. Kev ncua ntawm lub log mus yog torsion bar, qhov siab tshaj plaws ntawm kev thauj mus los ntawm txoj kev nruab yog nce txog 50 km / h. Qhov hnyav tag nrho ntawm S-40 yog 1824 kg. Kev xa tawm / folding rab phom nyob rau lub sijhawm yog kwv yees li 60 vib nas this. Tua ceev mus txog 20 rds / min.
S-40 anti-tank phom mos txwv
Cov cuab yeej tiv thaiv sub-caliber thiab lub foob pob hluav taws tawg loj tau xaiv los ua cov mos txwv tseem ceeb rau rab phom. Cov phom me me uas ua los ntawm subcaliber muaj qhov ntev 84 cm thiab qhov hnyav ntawm 6.3 kg. Cov tub ntxhais uas siv riam phom (25mm) hnyav me ntsis ib nrab ib phaus. Hmoov hnyav 2.94 kg. Tag nrho cov no tau muab cov projectile nrog lub davhlau siab (thawj 1330 m / s), muaj peev xwm tua tau ntau txog li 1500 metres thiab nkag tau yooj yim tiv thaiv cov cuab yeej rau qhov ntsuas no:
- ntawm qhov deb ntawm 0.5 km, qhov projectile nkag mus thaum nws tsoo 285mm ntawm kev tiv thaiv kev tiv thaiv riam phom;
- ntawm qhov deb ntawm 1 kilometers, qhov projectile nkag mus thaum nws tsoo 230mm ntawm kev tiv thaiv kev tiv thaiv riam phom;
- ntawm qhov deb li 1.5 km, qhov projectile tau nkag mus thaum nws tsoo 140mm ntawm kev tiv thaiv tej cuab yeej.
Cov mos txwv OFZT muaj qhov ntev 89 cm thiab qhov hnyav ntawm 9.3 kg. Qhov hnyav ntawm qhov projectile yog 4.2 kg, qhov hnyav ntawm cov foob pob tawg yog 105 grams. Qhov hnyav ntawm tus neeg tua hluav taws yog 1.3 kg, lub davhlau nrawm mus txog 783 m / s.
Kev sib piv ntawm C-40 thiab PaK 41
Soviet sib piv ntawm 7, 5 cm RAK-41 cannon (Grabin system) tau zoo dua cov qauv piv txwv ntawm cov khoom siv foob pob hluav taws thiab cov cuab yeej nkag mus yam ntxwv, rau kev sib piv: ntawm qhov deb ntawm 0.5 km, German rab phom nkag mus rau hauv cov cuab yeej mus txog 200mm (C -40 txog 285mm).
Txoj hmoo ntawm S-40 phom tiv thaiv lub tank
Kev tsim ua qauv ntawm S-40 rab phom tau ua tiav ntawm lub Hoobkas thiab kev sim uas tau tshwm sim xyoo 1947. Qhov tseeb thiab cov cuab yeej nkag ntawm sub-caliber armor-piercing mos txwv tau siab dua li ntawm 57mm caliber mos txwv ntawm ZIS-2 phom tiv thaiv lub tank raug sim. Tab sis OFZT mos txwv tsis zoo rau kev faib cov mos txwv (ZIS-2) hais txog kev ua tau zoo (kev faib ua ntu zus). Xyoo 1948, kev tshuaj xyuas thaj tsam ntawm S-40 txuas ntxiv mus. Tab sis, hmoov tsis zoo, vim muaj kev muaj sia nyob tsawg thiab muaj qhov nyuaj ntawm cov khoom siv thev naus laus zis, S-40 rab phom tiv thaiv lub tank tsis nkag rau hauv kev pabcuam nrog rau cov tub rog loj.
