An-124

The Antonov An-124 Ruslan is a large, strategic airlift, four-engined aircraft that was designed in the 1980s by the Antonov design bureau in the Ukrainian SSR, then part of the Soviet Union (USSR).

Externally, the An-124 is similar to the American Lockheed C-5 Galaxy, having a double fuselage to allow for a rear cargo door that can open in flight without affecting structural integrity.

An-124

It is slightly shorter, with a slightly greater wingspan, and a 17% larger payload.

Instead of the Galaxy’s T-tail, the An-124 uses a conventional empennage, similar in design to that of the Boeing 747.

An-124

The An-124’s main engine is the Lotarev D-18 (238–250 kN).

The aircraft uses oleo strut suspension for its 24 wheels.

The suspension has been calibrated to allow landing on rough terrain and is able to kneel to allow easier front loading.

An-124

The plane has an onboard overhead crane capable of lifting up to 30 tonnes of cargo, and items up to 120 tonnes can be winched on board.

Up to 150 tonnes of cargo can be carried in a military An-124, it can also carry 88 passengers in an upper deck behind the wing centre section.

An-124

The cargo compartment of An-124 is 36×6.4×4.4 m (118×21×14 ft), ca. 20% larger than the main cargo compartment of the C-5 Galaxy, which is 36.91×5.79×4.09 m (121.1×19.0×13.4 ft).

Due to limited pressurization in the main cargo compartment (24.6 kPa, 3.57 psi), it seldom carries paratroopers.

An-124

Pilots have stated that the An-124 is light on the controls and easy to handle for an aircraft of its size.

Some airports require pavement protection from the heat and blast effects of the An-124’s 2 TA18-200-124 auxiliary power units.
