Abstract: The present invention relates to an assembly of three wings joined with or without marginal plates, for aerial, water, land or space vehicles, to reduce induced drag and interference drag and provide greater manoeuvrability, independence in the fuselage design, optional installation of propulsion plant systems, an optional system of landing gears, increased maximum speed and reduced minimum speed, it being possible to reach zero speed or hover. The assembly also allows flight forwards, backwards, sideways, upwards and downwards or rotations about the axes of the vehicle.
