A new Russian concept aircraft is designed to fly high by staying down low. Russia's Central AeroHydrodynamic Institute named after N.E. Zhukovsky (TsAGI) is developing a new heavy transport aircraft for intercontinental routes that carries up to 500 tonnes (492 tons) of cargo in a blended wing that combines the wing and the fuselage of the aircraft, yet only reaches an altitude of between three and 12 m (10 and 40 ft) over water and land.

The low-flying leviathan is what is known in aviation circles as a Ground Effect Vehicle (GEV). A GEV is a form of aircraft that uses short, wide wings to trap a layer of air between the undersurface of the aircraft and the ground, producing vortices and downdraughts that generate more lift and less drag at very low altitudes, which allows the craft to carry heavy loads with less fuel. Here, the effect is produced by wings that blend into the body of the aircraft to not only create more lift, but also provide more interior space for cargo.

If it ever reaches the production stage, the TsAGI transport will be capable of taking off and landing on conventional runways and will carry standardized containers that would be loaded inside the wings through flap doors on the leading edge of the body and wing. According to the designers, the center section will hold the cockpit and a tank of cryogenic liquefied natural gas. This unconventional fuel was selected because it's lighter and burns cleaner, yet with much higher efficiency and safety than standard aviation fuel.
