TsAGI unveils new concept of flying wing heavy transport aircraft
 
Russia’s Central Aerohydrodynamic Institute (TsAGI) is developing a concept of a heavy transport plane with the wing-fuselage configuration, the institute’s press office said on Jan. 16, 2017. The wing-fuselage configuration will allow using the internal volume as effectively as possible and increase aerodynamic effectiveness, the press office added.

The future heavy transport plane is being developed to haul big cargo weighing up to 500 tons from one continent to another. Standard containers can be used. They are supposed to be accommodated by the cargo bays in the wings and boarded through hatches of the forebody slats of the plane’s central part.

The plane is planned to be operated by relevant airfields. The main part of the flight is performed by planes of the type at an altitude of 3-12 meters above water, ice or the ground.

Such surfaces create the ground effect that increases the aerodynamic quality and, as a result, reduces fuel consumption and boosts the range.

A model was made as part of the research work on the concept and tested in the TsAGI wind tunnel. The model was tested in the cruiser, takeoff and landing regimes.

A special screen looking like a round-ended plate was used to simulate the water, ice and ground surfaces.

The trials showed that the model had a high degree of aerodynamic efficiency both near the screen and without it, which will allow performing stable and controllable flights. The future plane is planned to be powered by liquefied natural gas. Unlike aviation kerosene, this cryogenic propellant has high energy efficiency and decreased hazardous emissions.

The natural gas will make flights environmentally friendly and ensure the competitiveness of the Russian-made plane on the global market.
