Kurwisa helikopta Kamow Ka-50 uye Ka-52 chikamu chekutanga
Chigaro-chimwechete kurwisa helikopta Ka-50 iri kushanda pamwe nemauto ehondo yekurwisa ndege yekudzidzira nzvimbo muTorzhek. Pamusoro payo, iyo Russian Air Force yakashandisa matanhatu Ka-50s chete; mamwe aishandiswa kudzidzira.
Iyo Ka-52 ihelicopter yekurwa yedhizaini yakasarudzika ine maviri coaxial rotors, vashandi vevaviri vakagara padivi nepadivi muzvigaro zveejection, vane zvombo zvine simba zvakanyanya uye midziyo yekuzvidzivirira, uye ine nhoroondo inotoshamisa. Yayo yekutanga vhezheni, iyo Ka-50-seat-seat fight helicopter, yakapinda mukugadzirwa makore makumi mana apfuura, muna Chikumi 40, 17. Apo helikopta yakazogadzirira kugadzirwa kwe serial, Russia yakapinda mudambudziko rakadzika rehupfumi uye mari yakapera. Makore makumi maviri chete gare gare, muna 1982, kuendeswa kumauto emhando yakagadziridzwa, yezvigaro zviviri zveKa-20 yakatanga. Kubva Kukadzi 2011 wegore rino, Ka-52 helicopters vanga vachitora chikamu muRussia kurwisa Ukraine.
Muchikamu chechipiri chemakore ekuma60, Hondo yeVietnam yakasangana ne "helicopter boom": nhamba yezvikopokopo zvekuAmerica ikoko yakawedzera kubva pa400 muna 1965 kusvika ku4000 muna 1970. MuUSSR, izvi zvakaonekwa uye zvidzidzo zvakadzidzwa. Musi waKurume 29, 1967, Mikhail Mil Design Bureau yakagamuchira rairo yekuvandudza pfungwa yehondo helicopter. Pfungwa yeSoviet kurwisa helikopta panguva iyoyo yakanga yakasiyana pane yekuMadokero: kunze kwezvombo, zvakare yaifanira kutakura timu yevarwi. Pfungwa iyi yakamuka nekuda kwekuda kwevatungamiriri vemauto eSoviet mushure mekuiswa kweBMP-1966 mauto ehondo yehondo ine hunhu hwakasiyana muSoviet Army mugore re1. Iyo BMP-1 yakatakura mauto masere, aive nenhumbi dzokurwa uye aive akapakatira 2-mm 28A73 low-pressure cannon uye Malyutka anti-tank inotungamirwa makomba. Kushandiswa kwaro kwakavhura mikana mitsva yehunyanzvi yemauto epasi. Kubva pano pfungwa yakasimuka kuti ienderere mberi uye vagadziri veherikoputa vakaraira "motokari inobhururuka yevacheche."
Muchirongwa cheKa-25F chikopokopo chemauto naNikolai Kamov, injini, mabhokisi egiya uye rotor kubva kuKa-25 marine helikopta yakashandiswa. Akarasikirwa mumakwikwi kuenda kuMi-24 helikopta yaMikhail Mil.
Mikhail Mil chete ndiye akapiwa basa kekutanga, sezvo Nikolai Kamov "nguva dzose" aigadzira helicopter dzehondo; aishanda chete nezvikepe uye haana kuverengerwa nendege yemauto. Zvisinei, Nikolai Kamov paakaziva nezvehurongwa hwechikopokopo chehondo, akarongawo chirongwa chake.
Kamov kambani yakagadzira dhizaini yeKa-25F (yekumberi-mutsara, zvine hungwaru), ichisimbisa mutengo wayo wakaderera nekushandisa zvinhu zveyazvino Ka-25 naval helikopta, iyo yakagadzirwa-zhinji paUlan-Ude chirimwa kubva muna Kubvumbi 1965. Chimiro chekugadzira cheKa-25 chaive chekuti simba remagetsi, giya guru uye rotor yaive yakazvimirira module inogona kuvharwa kubva kune fuselage. Kamow akakurudzira kushandisa iyi module muherikoputa itsva yemauto uye angowedzera muviri mutsva kwairi. Muimba yevatyairi, mutyairi wendege nepfuti vakagara padivi nepadivi; ipapo pakanga pane nhare navarwi gumi navaviri. Mune vhezheni yekurwa, pachinzvimbo chevarwi, helikopta yaigona kugashira makomba ekurwisa matangi anodzorwa nemiseve yekunze. Pasi pefuselage mune yekuisa nhare yaive 12-mm pfuti GSh-23. Ndichiri kushanda paKa-23F, boka raKamov rakaedza neKa-25, kwakabva radar nemidziyo yekudzivirira pasi pemvura yakabviswa uye UB-25-16 S-57 5-mm multi-shot rocket launchers yakaiswa. Iyo skid chassis yeKa-57F yakarongwa nevagadziri seyakasimba kupfuura iyo ine mavhiri chassis. Gare gare, izvi zvakaonekwa sechikanganiso, sezvo kushandiswa kwekare kune musoro chete kune chiedza helicopter.
Ka-25F yaifanirwa kunge iri chikopokopo chidiki; maererano neprojekti, yaive nehuremu hwe8000 kg uye maviri GTD-3F gasi turbine injini ine simba re2 x 671 kW (900 hp) yakagadzirwa neDesign Bureau yeValentin Glushenkov muOmsk; mune ramangwana, vakarongerwa kuwedzera kusvika 932 kW (1250 hp). Zvisinei, sezvo purojekiti yakanga ichiitwa, zvaidiwa nemauto zvakakura uye zvakanga zvisisakwanisi kuvagutsa mukati megadziriro yezviyero uye uremu hweKa-25. Semuenzaniso, mauto aida nhumbi dzokurwa dzemutyairi wevatyairi vendege nevatyairi vendege, izvo zvakanga zvisiri mugwara rekutanga. GTD-3F injini dzaisagona kurarama nemutoro wakadaro. Zvichakadaro, boka raMikhail Mil harina kugumira kune mhinduro dzaivepo uye rakagadzira yake Mi-24 helicopter (purojekiti 240) semhinduro itsva zvachose ine injini mbiri itsva dzeTV2-117 dzine simba re 2 x 1119 kW (1500 hp) .
Nokudaro, Ka-25F yakarasikirwa neMi-24 mumakwikwi ekugadzira. Musi waMay 6, 1968, nechisungo chakabatana cheCentral Committee yeCPSU uye Council of Ministers yeUSSR, imwe helicopter yehondo yakarairwa muMila brigade. Sezvo "inobhururuka mauto ekurwa mota" yaive yekutanga, iyo prototype "19" yakaedzwa munaGunyana 1969, 240, uye munaNovember 1970 Arsenyev chirimwa chakaburitsa yekutanga Mi-24. Iyo helikopta mukugadziriswa kwakasiyana-siyana yakagadzirwa muhuwandu hwemakopi anopfuura 3700, uye muchimiro cheMi-35M ichiri kugadzirwa nechirimwa muRostov-on-Don.
