Antonov An-124 Ruslan ASCC codename: Condor Heavy Transport





Deskripsi:
Sebelum adanya An-225, Antonov An-124 adalah pesawat terbesar di dunia, mengalahkan C-5 Galaxy. An-124 dibuat berdasarkan pengalaman dalam pembuatan turboprop raksasa An-22 dengan beberapa pengembangan yang membuat An-124 lebih efektif.




An-124 dilengkapi dengan sebuah hidung tergantung-menghadap atas dan sebuah lerengan untuk kemampuan roll-on roll-off loading (pengangkutan). Sebagai tambahan, dua set roda hidung yang dapat direndahkan untuk merendahkan hidung dan memudahkan pengangkutan kargo. Desain An-124 mempunyai full-span leading-edge slats pada sayapnya yang memungkinkan kemampuan take-off jarak pendek. Roda pendaratannya mempunyai 24 roda sehingga An-124 dapat beroperasi pada medan yang berat. Kompartemen besar untuk 88 penumpang sebagai tambahan pada dek kargo utama 118 ft x 21 ft x 14.5 ft, dengan total volume 44.725ft3.




An-124 pertama kali beroperasi untuk Aeroflot yang digunakan sebagai pesawat kargo besar. Sejumlah An-124 digunakan oleh militer Rusia untuk misi transpor strategis. Total 54 An-124 dibuat dari 1984 sampai 1997. Pada tahun 2000, 26 beroperasi untuk AU Rusia, 21 beroperasi untuk maskapai penerbangan sipil dan 5 hilang pada kecelakaan. Keterbatasan dana membuat produksi untuk militer dihentikan dan untuk komersial tetap berjalan, 3 pesawat tiap tahun hingga 2003. Walaupun pembuatannya telah dihentikan, tetapi Rusia dan Ukraina setuju untuk memulai kembali produksi pada semester kedua tahun 2008 jika jumlah pesanan memenuhi target.

KNOWN VARIANTS:
An-124: Military transport model
An-124A: Proposed military version that would have used six sets of tandem wheels on the main gear instead of five to permit operations from rougher airfields
An-124-100: Civil version modified for compatability with cargo loading infrastructure at commercial airports
An-124-100M: Improved model equipped with uprated D-18 Series 3 engines allowing greater range and shorter takeoff distance, also fitted with more advanced Western avionics allowing crew size to be reduced from 6 to 4 by eliminating the communication operator and engineer
An-124-100V: An-124-100 aircraft modified with noise-reduction covers on the engine nacelles to meet noise pollution standards
An-124-100MV: Model incorporating the improvements of both the An-124-100M and An-124-100V versions
An-124-100M-150: Upgrade for An-124-100M models to increase payload and maximum takeoff weight, extend flight hours from the original 7,500 to 24,000 (and ultimately 40,000), and replace outdated equipment
