An-26 yog ib lub dav hlau thauj tub rog zoo tshaj plaws ntawm Antonov Design Bureau. Txawm hais tias qhov tseeb tias nws cov khoom loj tau pib ntev dhau los, nws tseem nquag siv hauv ntau lub tebchaws. Nws yog indispensable tsis tau tsuas yog nyob rau hauv tub rog thauj, tab sis kuj nyob rau hauv civil aviation. Muaj ntau qhov kev hloov kho ntawm An-26. Lub dav hlau hu ua "Ugly Duckling".
Creation
Tom qab kawg ntawm Kev Tsov Rog Thoob Ntiaj Teb thib Ob, USSR tau xav tau ntau lub dav hlau uas muaj peev xwm txaus siab rau cov kev xav tau ntawm tsis yog Ministry of Defense nkaus xwb, tab sis kuj tseem siv dav hlau dav hlau. Nyob rau hauv nruab nrab ntawm lub xyoo pua 20th, lub teb chaws tus thawj coj txiav txim siab pib nws creation.
Txoj haujlwm no tau tso siab rau Antonov Design Bureau, uas muaj kev paub dhau los hauv kev tsim lub dav hlau thauj. Txoj cai sib raug tau kos npe rau xyoo 1957, tom qab ntawd kev tsim ntawm An-26 pib. Lub dav hlau ua nws thawj lub davhlau nyob rau hauv 1969, thiab twb nyob rau hauv 1973, nwstau muab tso rau hauv kev ua haujlwm hauv USSR.
Ntse
Ua tsaug rau ntau qhov kev tsim tshwj xeeb uas siv rau nws qhov kev tsim, nws qhov kev ua tau zoo, thaum lub sijhawm ua haujlwm, yog thawj chav kawm. Lub dav hlau An-26, qhov kev piav qhia ntawm cov ncauj lus kom ntxaws, yog qhov zoo dua rau cov dav hlau zoo sib xws.
An-26 aircraft, specifications:
- Crew: 5 tus neeg.
- Peev: 5.6 tons.
- Ib txwm nqa hnyav: 23 tons.
- siab tshaj tawm qhov hnyav: 24 tons.
- Tus nqi roj hauv lub tank sab hauv: 7.0 tons.
Cov neeg caij tsheb: 38 tus tub rog, lossis 30 tus neeg caij tsheb thauj neeg mob, lossis, hauv lub tsheb thauj neeg mob, 24 tus neeg raug mob ntawm stretchers.
Kev Ua Haujlwm:
- Cruising speed: 435 km/h
- siab tshaj plaws: 540 km/h
- Kev siv qab nthab: 7300 m.
- Tus nqi nce: 9.2 m / s.
- Kev siv ntau yam: 1100 km.
- Roj ntau: 2660 km.
Vim muaj plaub lub nqaj tuav ntawm nws, nws muaj peev xwm nqa cov foob pob hnyav txog li 500 kg thiab tau txwv tsis pub siv los ua tus foob pob. Lub dav hlau An-26, uas nws cov yam ntxwv ua haujlwm tau nyob rau theem siab tshaj plaws rau nws lub sijhawm, tuaj yeem siv los daws ntau yam haujlwm.
Npaj
Lub fuselage ntawm lub dav hlau no muaj plaub qhov chaw:
- nasal;
- nruab nrab;
- hatch;
- tail.
Taudocking yog nqa tawm ntawm daim tawv nqaij. Feem ntau nws yog ua los ntawm aluminium alloys thiab duralumin. Lub fuselage tsev lub cockpit thiab lub cargo compartment. Lub tom kawg muaj ib tug built-in conveyor, thiab nyob rau hauv lub Upper ib feem muaj ib tug monorail nrog ib tug talfer. Lawv tsim nyog rau kev ua haujlwm ntawm kev thauj khoom thiab tshem tawm An-26. Lub dav hlau, ua tsaug rau lawv lub xub ntiag, tuaj yeem nqa lossis nqa cov khoom thauj hauv lub sijhawm luv tshaj plaws.
Nws muaj ib qho nkag thiab plaub qhov rooj xwm txheej ceev hauv nws lub fuselage. Tsis tas li ntawd, muaj kev ua haujlwm thiab cov khoom thauj khoom. Rau kev sib khi zoo dua ntawm An-26 cabins, qhov rooj thiab lub kaus mom, siv lub sealant tshwj xeeb thiab cov roj hmab profile.
Cov tawv nqaij ntawm lub dav hlau yog ua los ntawm duralumin nplooj ntawv, lub thickness ntawm 0.8 mus rau 1.8 hli. Lawv txuas nrog hluav taws xob vuam, cov kua nplaum tshwj xeeb lossis rivets.
Wing
An-26 muaj lub cantilever, siab-dav duab plaub. Nws suav nrog ib qho chaw nruab nrab, detachable thiab nruab nrab. Lawv docking yog ua tiav siv lub luj tshib, connector profiles thiab fittings.
Raws li nws tsim, An-26 tis (daim duab ntawm lub dav hlau lees paub qhov no), yog hom caisson thiab suav nrog stringers, tawv nqaij thiab 23 tav. Muaj cua sov ntawm cov ntiv taw ntawm tis, uas tiv thaiv icing. Lub thickness ntawm sheathing txawv nyob ntawm qhov chaw. Ntawm tus Tsov tus tw muaj aileron thiab nrov plig plawg tswj pas nrig.
Stabilizer thiab of elevator
An-26 stabilizer suav nrog ob lub consoles,Txhua tus muaj tus Tsov tus tw, qhov ntswg, kawg fairing, hauv qab thiab sab saum toj vaj huam sib luag. Cov stringers yog fastened rau ntawm daim tawv nqaij siv tshwj xeeb hluav taws xob welding, thiab lawv tsuas yog glued rau spars thiab tav. Lub stabilizer txuas nrog lub fuselage nrog fittings thiab bolts.
Tim tabs tau teeb tsa rau ntawm txhua qhov ntawm An-26 of the elevator, thiab lawv raug tswj los ntawm kev txav lub kauj tsheb deb ntawm koj lossis ntawm koj. Vim lub fact tias cov kev tswj yog duplicated thiab yuav ua tau los ntawm ob pilots, qhov kev cia siab ntawm lub aircraft yog nce. Lub elevator tseem tau nruab nrog autopilot, uas tso cai rau cov kws tsav dav hlau so thaum lub davhlau. Koj tuaj yeem tswj lub elevator manually tom qab lub autopilot raug kaw.
Chassis
Cov khoom tsaws ntawm lub dav hlau muaj ib sab pem hauv ntej thiab ob txhais ceg loj. Cov tom kawg yog nyob rau hauv lub cav nacelles thiab tom qab takeoff raug tshem tawm mus rau tshwj xeeb compartments. Txhua lub ntsiab txhais ceg muaj disc nres thiab ob lub log nruab nrog inertial sensors.
Retracting and expanding the landing gear of the aircraft yog ua tsaug rau lub xub ntiag ntawm hydraulic lub tog raj kheej fais fab. Thaum muaj kev ua haujlwm tsis zoo, kev tso tawm tuaj yeem ua tiav manually, ua tsaug rau lub taub hau thiab tus kheej qhov hnyav.
tsob nroj muaj zog
An-26 yog nruab nrog ob lub cav turboprop, txhua qhov muaj peev xwm ntawm 2829 horsepower. Lawv raug ntsia rau hauv gondolas nyob rau ntawm qhov chaw nruab nrab. Lub cav yog txuas nrog lub truss nrog ib tug ncej.
Power Planttswj thiab tswj los ntawm lub cockpit, nrog kev pab los ntawm cov cuab yeej tshwj xeeb thiab cov khoom siv. Qhov no yog ua tau vim muaj hluav taws xob, tshuab thiab tsis siv neeg tshuab nruab rau ntawm An-26. Lub dav hlau muaj lub tshuab fais fab zoo heev rau nws lub sijhawm.
Ntxiv rau lub kiv cua, lub cav yog nruab nrog:
- hood;
- fairing;
- cov roj sab nraud;
- tiv thaiv hluav taws;
- anti-icing system;
- roj system.
Kom tsis txhob muaj hluav taws kub hauv lub cav, qhov kub thiab qhov tso pa tawm yog cais tawm ntawm lub tis los ntawm cov ntxaij vab tshaus tshwj xeeb thiab baffles.
Muaj lwm lub cav nyob rau hauv tus Tsov tus tw ntawm lub dav hlau, uas yuav tsum tau tsim kom muaj zog ntxiv thaum nce. Tsis tas li ntawd, nws tso cai rau koj kom muaj zog lub dav hlau thaum nyob ruaj ruaj lossis thaum lub tshuab hluav taws xob tsis ua haujlwm.
Nws tseem yog qhov tseem ceeb rau qhov tsis ua haujlwm ntawm lub tshuab tseem ceeb. Nws lub xub ntiag ua rau nws tuaj yeem txo ntau qhov kev pheej hmoo uas tuaj yeem nrog An-26 lub dav hlau hauv davhlau. Phau ntawv saib xyuas muab cov ntaub ntawv qhia ntxaws txog cov txiaj ntsig ntawm lub cav tsav.
Xov xwm
Tag nrho An-26s uas yog ib feem ntawm USSR Air Force tau pleev xim rau hauv grey. Lub dav hlau siv nyob rau hauv civil aviation tau pleev xim rau hauv cov xim ntawm Aeroflot. Nyob rau hauv niaj hnub Russia, pej xeem An-26s (koj tuaj yeem pom ib daim duab ntawm lub dav hlau hauv tsab xov xwm) tau pleev xim nrog cov xim nyob ntawm qhov xav tau ntawm lub tuam txhab uas muaj lawv. Cov aircraft, uasua haujlwm txawv teb chaws, feem ntau muaj xim camouflage.
Dashboards ntawm lub dav hlau yog xim dub. Lub cargo compartment zoo dua li, piv txwv li, ntawm An-12. Phab ntsa painting yog ntsuab thiab phab ntsa thiab qab nthab yog dawb.
Result
Ua tsaug rau nws thawj-chav ya davhlau thiab cov yam ntxwv ntawm kev ua haujlwm, kev ntseeg tau thiab ntau yam, An-26 tau nrov thiab siv thoob plaws ntiaj teb. Nws pom tias nws siv rau hauv lub luag haujlwm ntawm kev thauj tub rog thiab cov neeg caij dav hlau. Tab sis lub xyoo coj lawv tus xov tooj hu, thiab yog hais tias ua ntej nws twb xam tau tias yog ib tug zoo heev aircraft, tam sim no nws yog obsolete. Lub An-26 tab tom raug txiav tawm ntawm kev pabcuam. Nyob rau hauv nws qhov chaw tuaj ntau niaj hnub aircraft, superior rau nws nyob rau hauv ntau txoj kev.
