The An-124 Ruslan, designed by the Antonov ASTC based in Kiev in
the Ukraine, is the world's largest and highest flying cargo capacity
aircraft in production. Its serial production has been launched at AVIANT
State Aviation Plant, Kiev, and AVIASTAR, Ulyanovsk, Russia. The aircraft,
which has the NATO reporting name Condor, is designed for long-range
delivery and air dropping of heavy and large size cargo, including
machines, equipment and troops.
The unique transport capabilities and the high performance of the
aircraft have been proven in operation. 20 An-124-100 of Antonov Airlines,
Volga-Dniepr, Poliot and other airlines transport different cargoes all
over the world; for example: 90-ton hydraulic turbines, large size
Liebherr autocranes, American Euclid dump trucks, the fuselage of Tu-204
passenger transporter, a 109-ton railway locomotive, and a sea yacht of
more than 25 metre length.
DESIGN
The aircraft fuselage has a double-deck layout. The cockpit, the relief
crew compartment and the troop cabin with 88 seats are on the upper deck.
The lower deck is the cargo hold. The flight deck has crew stations
arranged in pairs for six crew - the pilot and copilot, two flight
engineers, the navigator and communications officer. The loadmaster's
station is located in the lobby deck.
The An-124 aircraft is fitted with a relatively thick (12 %) sweptback
supercritical wing to give high aerodynamic efficiency and consequently a
long flight range. The construction includes extruded skin panels on the
wing, extruded plates for the centre-section wing panels and monolithic
wafer plates for the fuselage panels. The aircraft structural members are
made of composites that make up 1,500 square metres of the surface area.
Multi-leg landing gear and loading equipment ensure self-sufficient
operation of the aircraft on prepared concrete runways and on unpaved
strips. The landing gear is self-orienting and incorporates a kneeling
mechanism which allows an adjustable fuselage clearance to assist the
loading and unloading of self-propelled equipment.
CARGO SYSTEMS
The on-board system of cargo handling equipment make it possible to
load and unload the aircraft without the help of ground facilities. The
paradropping and cargo-handling equipment comprises two travelling cranes,
two winches, rollgang and tiedown equipment. The aircraft is often
compared to the US Lockheed Martin C-5 Galaxy. The An-124 has a
transportation capability 25% higher than that of the C-5A and 10% higher
than the C-5B.
The two cargo hatches are a distinctive structural feature. The
fuselage nose can be hinged upward to open the front cargo hatch and there
is a cargo hatch in the rear fuselage.
AVIONICS
All systems are quadruple redundant. The on-board equipment provide the
capability to execute airlift and paradrop missions by day and at night,
in visual flight rules and instrument flight rules (VFR and IFR) weather
conditions. There are 34 computers functioning aboard the aircraft,
combined into four main systems: navigation, automatic piloting, remote
control and monitoring.
The integrated flight control and aiming-navigation system comprises an
autonomous navigation system, altitude and airspeed indicating system,
combat formation flight control equipment, short-range radio navigation
and landing system, global positioning system, automatic radio compass,
ground surveillance radar, forward-looking weather radar, optical and TV
sight and IFF equipment.
AN-124-210 AND AN-124-100M
Antonov, Aviastar and Air Foyle of the UK have jointly submitted a
proposal to the UK MoD for leasing of new versions, the An-124-210 and
An-124-100M. An-124-210 will be equipped with a Rolls-Royce RB211-52H-T
engine, An-124-100M with Series 3 D-18 engines, produced by Progress
Design Bureau in Zaporozhe. These engines allow an increase in service
range of 10% and reduced take-off distance. Both versions will be equipped
with digital instrumentation and displays from Honeywell of the USA and
Aviapribor of Russia, enabling the crew size to be reduced from 6 to 4.
Also fitted are: traffic alert collision and avoidance system (TCAS 2000),
ground proximity warning system and satellite communications
system.
