Russian researchers have released details of a proposed medium-haul widebody aircraft design which has been undergoing structural studies at the Central Aerohydrodynamics Institute.

The main characteristic of the twin-engined aircraft, designated the 'Frigate EkoJet', is an elliptical fuselage which would accommodate 300-350 passengers in a three-class, triple-aisle configuration.
