he An-225 utilizes six Progress D-18 turbofans, each producing 51,600 lbf of thrust to haul its massive loads of cargo. This massive plane holds the world records airlifting a single-item payload—a gas power station generator weighing 418,834 pounds—and for airlifting a total payload of 559,577 pounds.
The An-225 loads and unloads through its nose—the rear ramp and cargo door were removed to save weight—and actually kneels using its retractable nosegear, allowing deliveries to drive directly into the cargo bay and more easily position loads. The Mriya also differs from the earlier Ruslan in its tail assembly. The An-225 uses a split, twin tail—rather than the single vertical fin—that allows it to carry large external items up to 440,000 pounds. - www.gizmodo.com
