Mi-2 (nyoob hoom qav taub): specifications thiab cov duab

Tus tsim ntawm lub Mi-2 yog ib tug kev loj hlob ntawm Ni-turbine 1, nyob rau ntawm qhov chaw kawm lub fuselage tshaj ob tug me me roj turbine xyaw muaj muaj rau payload tag nrho alarm cheeb tsam. Nyob rau hauv cov creation ntawm ib tug tshiab aircraft, nws los ua lub npe hu nyob rau hauv lub Autumn ntawm 1961 thiab cov thawj Mi-2 ob xyoos tom qab nrog ob tug turbine "Izotov GTD-350" nrog lub peev xwm ntawm 400 liters. ib tug. txhua mounted sab ntawm sab saum toj no lub tsheb tav xis.

ntsiab kev pab raws qib

Lub aircraft yog tsim los ua tib yam kev pab raws qib rau cov thauj ntawm khaub-ncaws nyias khoom, txawm li cas los kawm Mi-1. Neeg nrog caij version yuav nqa 7 neeg thiab ib tug tsav. Nyob rau hauv lub luag hauj lwm ntawm cawm aircraft Mi-2 accommodates plaub stretchers thiab ib tug kho mob ua hauj lwm. Lub nkoj qab thus muaj peev xwm sawv ntawm nqa loads ntawm mus txog 700 kg. Raws li cov ya crane lossis los ua tau cawm tsheb yuav txawm peem rau ventral sib ntsib rau dai load hnyav txog li 800 kg los yog saum toj no lub alarm qhov rooj winch muaj peev xwm ntawm lifting mus txog 150 kg. Qhov thib plaub lub ntsiab daim ntawv thov uas distinguishes nyoob hoom qav taub Mi-2 - exploitation nyob rau hauv ua liaj ua teb, rau cov uas nws yuav yuav txawm peem rau nrog tso tsheb hlau luam uas muab tso rau ntawm ob sab ntawm lub tsheb tav xis, tau tuav 450 kg ntawm qhuav tshuaj los yog 500 liters. Yuav kom ua tau lwm yam kev pab raws qib cargo tso tsheb hlau luam yuav tsum tau hloov nrog cov roj ntxiv.

Keeb kwm ntawm creation

Mi-2 (saib duab. Nyob rau hauv lub daim ntawv ntsuam xyuas) twb tau nyob rau hauv lub WSK Hoobkas nyob rau hauv Mielec nyob rau hauv teb chaws Poland. Tom qab kev sib khom lus, pib nyob rau hauv Lub ib hlis ntuj 1964, lub WSK tau txais tsuas yog txoj cai los tsim lub aircraft thiab nws xyaw. Nws yuav tsum tau hloov lub Mi-1 cov tub rog aircraft thiab yuav tseem ceeb rau rau lub "Aeroflot" raws li tsheb thauj neeg mob thiab cua taxis. Ib txhia Mi-2, yog ntseeg kom tau tauj mus rau lub tebchaws United Arab koom pheej, ntawm qhov chaw uas lawv yog cov yuav mus poob rau hauv cov Yixayee.

Nyob rau hauv nruab nrab-fifties mais Bureau tau txiav txim siab mus tsa tus Mi-1 kev ua tau zoo los ntawm txoj kev loj hlob ntawm nws cov version ntawm lub turbine. Yuav kom qhov no kawg, ob tug tshiab roj turbine engine nrog ib tug dawb turbine "Izotov GTD-350" tau raug xaiv. Uas, nws yog ib nrab tus luj ntawm lub qub piston nrog combustion xyaw, ob GTD-350 twb 40% muaj zog. Lawv yog mounted sab ntawm sab saum toj no lub fuselage, uas ho tsub kom cov muaj alarm qhov chaw thiab pab txoj kev kawm ntawm cov Mi-2. Tej powerplant tso cai los mus hloov lub muab kev ceev ntawm lub ntsia hlau, kom lub cav ceev qhov.

aircraft tsab hu ua B-2, thiab tom qab renamed Mi-2. Lub nyoob hoom qav taub thawj ya mus nyob rau hauv lub Cuaj Hli Ntuj 1961 Nws yog tib yam rotor, kis tau tus mob thiab tus Tsov tus tw, xws li cov Mi-1. Tom qab pre-test twb dhau nws yog xim hlau tus Tsov tus tw rotor (1-y Ni yog ntoo) thiab ces nrog 1965, muaj ib tug tshiab lub tes tsho nqa ib rotor, noj cov Mi-6.

Txij li thaum Soviet factories tau siab koom nyob rau hauv zus tau tej cov Mi-8 thiab lwm yam hnyav Mi series, tam sim no WSK-Swidnik ntawv cog lus tau mus txog rau hauv qhuav thiab ntxiv kev loj hlob ntawm lub Mi-2 nyob rau hauv teb chaws Poland, uas pib nyob rau hauv 1964. Tus thawj Polish Mi-2 mus rau qhov no nws ua nws hluas nkauj sib ntaus nyob rau hauv Kaum ib hlis 1963, thiab tom qab kawm tiav ntawm lub xeem nyob rau hauv 1965, pib nws loj-scale lawm. Tus thawj serial Mi-2 yog nruab nrog motors 400 l. sec., tab sis nyob rau hauv 1974 qhov no parameter tau ntau zog rau 450 liters. ib tug. Cov kev siv ntawm cov iav nyob rau hauv lub ntsiab rotor, tus Tsov tus tw rotor thiab stabilizer piv ntau lawm thiab txhim kho productivity.

Rau pej xeem thiab cov tub rog kev siv txawv versions ntawm lub Mi-2 tau ua. Nyoob hoom qav taub nyob rau hauv qhov kev pab nrog cov Polish Cua Dag Zog Yuam, yog nruab nrog foob pob ua ntxaij launchers thiab cua-rau-av missiles, uas yog launched los ntawm cov ntsia rau sab ntawm lub fuselage.
