I ka makahiki 1935, ua hoʻokomo ʻia kahi hoʻololi hou o nā pahu BT, i loaʻa i ka index BT-7, a hoʻokomo ʻia i loko o ka hana nui. Ua hana ʻia ka pahu a hiki i 1940 a ua hoʻololi ʻia i ka hana ʻana e ka pahu T-34. (E heluhelu pū hoʻi i ka "Medium Tank T-44") Ke hoʻohālikelike ʻia me ka pahu BT-5, ua hoʻololi ʻia kona hoʻonohonoho hull, ua hoʻomaikaʻi ʻia ka pale pale kaua, a ua hoʻokomo ʻia kahi ʻenekini hilinaʻi. Ua hana mua ʻia kahi ʻāpana o ka hoʻopili ʻana o nā pā kaua o ka hull e ka welding.
ʻO nā ʻano like ʻole o ka pahu i hana ʻia:
- BT-7 - kahi pahu laina me ka lekiō ʻole; mai ka makahiki 1937 ua hana ʻia me ka turret conical;
- BT-7RT - pahu kauoha me ka lekiō 71-TK-1 a i ʻole 71-TK-Z; mai ka makahiki 1938 ua hana ʻia me ka turret conical;
- BT-7A - pahu pahu; mea kaua: 76,2 mm KT-28 pū pahu a me 3 DT pū mīkini;
- BT-7M - kahi pahu me ka mīkini diesel V-2.
ʻO ka huina, ʻoi aku ma mua o 5700 mau pahu pahu BT-7 i hana ʻia. Ua hoʻohana ʻia lākou i ka wā o ka hoʻokuʻu ʻana ma Western Ukraine a me Belarus, i ka wā o ke kaua me Finland a me ke Kaua Patriotic Nui.
Pahu BT-7.
ʻO ka hana a me ka modernization
I ka makahiki 1935, hoʻomaka ʻo KhPZ i ka hana ʻana i ka hoʻololi hou o ka pahu, ʻo ka BT-7. Ua hoʻomaikaʻi kēia hoʻololi i ka hiki ʻana i ka ʻāina, hoʻonui i ka hilinaʻi a me ka maʻalahi o nā kūlana hana. Eia kekahi, ua hōʻike ʻia ka BT-7 i nā mea kaua mānoanoa.
Ua hoʻolālā hou ʻia nā pahu pahu BT-7, me ka nui o loko, a me nā mea kaua mānoanoa. Ua hoʻohana nui ʻia ka welding no ka hoʻopili ʻana i nā pā kaua. Ua hoʻokomo ʻia kahi mīkini M-17 o ka mana liʻiliʻi a me kahi ʻōnaehana hoʻololi i hoʻololi ʻia ma ka pahu. Ua hoʻonui ʻia ka mana o nā pahu wahie. Ua loaʻa iā BT-7 kahi puʻupuʻu nui hou a me kahi pahu pahu i hoʻolālā ʻia e A. Morozov. Ua hoʻohana ʻia nā paʻa paʻa ma luna o nā kaʻa kaʻa lana i hoʻolālā ʻia e Polofesa V. Zaslavsky. I ka makahiki 1935, ua hāʻawi ʻia ka mea kanu i ka Order of Lenin no ka pono o KhPZ ma ke kahua o ka hale tank.
Ma ka BT-7 o nā hoʻokuʻu mua, e like me ka BT-5, ua hoʻokomo ʻia nā hale kiaʻi cylindrical. Akā i ka makahiki 1937, ua hā'awi nā hale kia'i cylindrical i nā conical all-welded, i'ike'ia e ka mānoanoa o ka pale kaua maika'i. I ka makahiki 1938, ua loaʻa i nā kaʻa kaʻa nā hiʻohiʻona telescopic hou me kahi laina ʻike paʻa. Eia hou, ua hoʻomaka nā pahu e hoʻohana i nā enuhe split-link me kahi haʻahaʻa haʻahaʻa, i hōʻike maikaʻi iā lākou iho i ka wā holo wikiwiki. Pono ka hoʻohana ʻana i nā ala hou e hoʻololi i ka hoʻolālā ʻana o nā huila kaʻa.
ʻO kekahi mau BT-7 i hoʻolako ʻia i ka lekiō (me ka turret cylindrical) ua hoʻolako ʻia me kahi antenna handrail, akā ua loaʻa nā BT-7 me kahi turret conical i kahi antenna whip hou.
I ka makahiki 1938, ua loa'a i kekahi mau pahu laina (me ka lekiō) he pū mīkini DT hou i loko o ka niche turret. I ka manawa like, pono e hoemi iki ia na poka. Ua hoʻolako ʻia kekahi mau kaʻa me kahi pū mīkini anti-aircraft P-40, a me nā kukui hulina ikaika (e like me ka BT-5) aia ma luna o ka pū a lawelawe e hoʻomālamalama i ka pahu hopu. Eia nō naʻe, ma ka hoʻomaʻamaʻa, ʻaʻole i hoʻohana ʻia kēlā mau kukui wai, no ka mea, ua ʻike ʻia ʻaʻole maʻalahi lākou e mālama a hana. Ua kapa ʻia nā tankers i ka BT-7 "Betka" a i ʻole "Betushka".
ʻO ke kumu hoʻohālike hope loa o ka pahu BT ka BT-7M.
ʻO ka ʻike o ka hakakā ʻana ma Sepania (kahi i komo ai nā pahu BT-5) i hōʻike i ka pono e loaʻa kahi pahu ʻoi aku ka holomua ma ka lawelawe ʻana, a i ka pūnāwai o 1938, hoʻomaka ʻo ABTU e hoʻomohala i kahi pani i ka BT - kahi huila kiʻekiʻe. - Tracked tank me nā mea kaua like, akā ʻoi aku ka palekana a ʻoi aku ka pale ahi. ʻO ka hopena, ua ʻike ʻia ka prototype A-20, a laila ʻo ka A-30 (ʻoiai ke kūʻē nei ka pūʻali koa i kēia mīkini). Eia naʻe, ʻaʻole i hoʻomau ʻia kēia mau mīkini i ka laina BT, akā ʻo ka hoʻomaka ʻana o ka laina T-34.
E like me ka hana ʻana a me ka hana hou ʻana o nā pahu BT ma KhPZ, ua hoʻomaka lākou e hana i kahi mīkini pahu diesel ikaika, kahi i manaʻo ʻia e hoʻololi i ka mīkini carburetor M-5 (M-17) hiki ʻole ke hilinaʻi ʻia, capricious a me ke ahi. I ka makahiki 1931-1932, ua hoʻokumu ka NAMI / NATI Design Bureau ma Moscow, i alakaʻi ʻia e Professor A.K. Dyachkov, i kahi papahana no ka mīkini diesel D-300 (12-cylinder, V-shaped, 300 hp), i hoʻolālā kūikawā ʻia no ka hoʻokomo ʻana i nā pahu. . Eia nō naʻe, i ka makahiki 1935 wale nō, ua kūkulu ʻia ka prototype mua o kēia mīkini diesel ma ka Kirov Plant ma Leningrad. Ua kau ʻia ma ka BT-5 a hoʻāʻo ʻia. He mea hōʻeha nā hopena, ʻoiai ʻaʻole lawa ka mana diesel.
Ma ka KhPZ, ua hana ke keʻena 400th, i alakaʻi ʻia e K. Cheplan, i ka hoʻolālā ʻana i nā ʻenekini pahu pahu. Ua hui pū ka 'Oihana 400 me ke keʻena o nā ʻenekini o VAMM a me CIAM (Central Institute of Aircraft Motors). I ka makahiki 1933, ua puka mai ka engine diesel BD-2 (12-cylinder, V-shaped, hoʻomohala i 400 hp ma 1700 rpm, hoʻohana wahie 180-190 g/hp/h). I Nowemapa 1935, ua ho'okomo 'ia ka engine diesel ma ka BT-5 a ho'ā'o 'ia.
I Malaki i ka makahiki 1936, ua hōʻike ʻia ka pahu diesel i ka hui kiʻekiʻe, ke aupuni a me nā limahana koa. Pono ʻo BD-2 i ka hoʻomaʻemaʻe hou aku. ʻOiai kēia, ua hoʻokomo ʻia i ka lawelawe ma 1937, ma lalo o ka inoa B-2. I kēlā manawa, ua hoʻomaka ka hoʻonohonoho hou ʻana o ke keʻena 400th, e hoʻopau ana me ka hōʻike ʻana i Ianuali 1939 o ka Kharkov Diesel Building Plant (HDZ), i ʻike ʻia ʻo Plant No. 75. ʻO KhDZ ka mea i hana nui i nā diesel V-2.
Mai 1935 a 1940, 5328 BT-7 pahu o nā hoʻololi a pau i hana ʻia (ʻaʻole helu i ka BT-7A). Ua lawelawe pū lākou me nā pūʻali koa a me nā mekani o ka Pūʻali ʻulaʻula no ke kaua holoʻokoʻa.
