Qhov txaus ntshai sib xws: nyob rau tib hnub, Lub Yim Hli 3, 1938, peb lub dav hlau sib ntaus tshiab tau tawm thawj zaug hauv USSR, Great Britain thiab Ltalis. Txawm li cas los xij, rau ntau yam laj thawj, tag nrho peb tus qauv tsis haum rau cov tub rog, lawv tsis raug lees txais rau hauv kev pabcuam, thiab tom qab ib ntus lawv tau muab pov tseg.
Cia peb pib nrog peb tus swb - ntau lub hom phiaj dav hlau los ntawm tus kws tsim qauv dav hlau Nikolai Polikarpov, codenamed "Ivanov". Nws thawj lub davhlau tau xaus ib txwm, thiab qhov thib ob, uas tau tshwm sim nyob rau tib hnub ntawd, cov iav tsaws tsoo thaum lub sijhawm tsaws. Tom qab kho tas, kev ntsuam xyuas rov pib dua thiab txuas ntxiv mus txog xyoo 1940. Los ntawm lub sijhawm ntawd, kev sib tw ua qauv, Su-2 lub dav hlau, tsim los ntawm Pavel Sukhoi Design Bureau, twb tau txais yuav lawm thiab muab tso rau hauv ntau lawm. Txij li thaum Polikarpov "Ivanov" muaj kwv yees li sib npaug yam ntxwv nrog nws, tsis muaj ib qho tseem ceeb hauv kev hloov Sukhov lub dav hlau nrog nws. Hauv tib lub xyoo, txoj haujlwm tau raug kaw.
Hauv daim duab - "Ivanov" ntawm Central Aerodrome ua ntej thiab tom qab kev sim thaum Lub Yim Hli 3, 1938.
Hauv kev tsav dav hlau Askiv, qhov xwm txheej zoo ib yam. Lub tuam txhab Martin-Baker, ntawm nws tus kheej txoj haujlwm thiab siv nws cov peev txheej, tsim thiab tsim ib qho qauv ntawm MB-2 tus neeg tua rog, uas ua rau nws lub dav hlau ya yuav luag ib txhij nrog Ivanov. Lub dav hlau muaj tus lej zoo, tab sis tsis zoo li ntawd vim nws yog ib qho ntawm cov neeg tua hluav taws tshiab, Spitfire lossis Hurricane, tau tso tseg. Thiab kev saws me nyuam ntawm peb lub tshuab sib txawv ntawm tib lub hom phiaj rau kev pabcuam ib zaug tau txiav txim siab los ntawm cov kws tshaj lij Askiv tsis tas yuav tshaj. Raws li qhov tshwm sim, MV-2 qhia txog txoj hmoo ntawm "Ivanov".
MV-2 tau tsim los ua "dav hlau ua rog tag nrho" nrog rau kev siv cov khoom siv tsawg. Nws lub thav duab tau txuas los ntawm cov kav hlau, thiab ib feem tseem ceeb ntawm daim tawv nqaij yog daim ntaub. Lub dav hlau muaj lub tsaws tsaws tsaws tsaws tsag, uas thaum kawg ntawm xyoo 1930s twb tau txiav txim siab tias yog qhov qub, txawm li cas los xij, lub tuam txhab npaj yuav nruab nws nrog cov hlua uas thim rov qab tau yav tom ntej. Lub ntsiab "tseem ceeb" ntawm lub tsheb yog nws thawj lub zog cog-24-lub tog raj kheej H-puab lub tshuab cua txias Napier "Dagger". Qhov tseeb, nws suav nrog ob lub 12-lub tog raj kheej boxer lub cav tau teeb tsa ntawm ib qho crankcase. Qhov nyuaj dhau ntawm lub cav no poob qis ntawm kev cia siab.
Tsis tas li ntawd, xyuam xim rau "ntsia hlau" tawm ntawm lub cab hauv daim duab hauv qab no. Qhov no yog qhov tshwj xeeb tiv thaiv cabotage bar uas tiv thaiv lub tsheb los ntawm kev tsoo thaum lub tshuab tau ntxeev thiab txuas ntxiv thaum tsaws hauv qhov sib xyaw nrog cov tsaws tsaws. Raws li kuv paub, tsis muaj lwm lub dav hlau tau nruab nrog lub cuab yeej zoo li no.
Thaum kawg, thaum Lub Yim Hli 3, Ltalis pib sim hloov pauv tus qauv ntawm Caproni Ca-165 tus neeg tua rog. Nws yog ib qho ntawm European kawg biplane fighters. Hauv nws daim ntawv qub, nws tau tawm thawj zaug thaum Lub Ob Hlis, tab sis tom qab ntawd lub dav hlau tau rov ua haujlwm zoo. Tshwj xeeb, lub qhov taub zoo li lub qhov taub nrog lub qhov muag pom thoob plaws tau teeb tsa rau nws, thiab lub tshuab hluav taws xob rov qab tau hloov pauv nrog ib qho ruaj khov, zais nws hauv qhov ncaj qhov.
Lub dav hlau tau dhau los sai dua nws cov neeg sib tw tseem ceeb, Fiat CR-42 lub dav hlau tua hluav taws, tab sis tsis muaj peev xwm txav tau yooj yim, thiab rau cov tub rog sib ntaus sib tua nws yog qhov ua tau zoo uas tau suav tias yog tus yam ntxwv tseem ceeb. Lwm qhov tseem ceeb yog tus nqi qis dua ntawm Caproni - ib thiab ib nrab zaug ntau dua li ntawm Fiat. Kev sib xyaw ntawm cov xwm txheej no tau coj cov tub rog xaiv rau Fiat. Yuav luag 1,800 CR-42s tau tsim, thiab Ca-165 zoo nkauj tseem nyob hauv ib daim ntawv thiab tsis ntev nws tau xaus rau hnub ntawd.
Daim duab sab saum toj qhia pom Ca-165 hauv nws qhov kev teeb tsa thawj zaug, thiab daim duab hauv qab qhia nws tom qab kho dua tshiab.
