A hovering or VTOL aircraft with a propulsion unit using a fan in a shroud whose upper end is toroidally shaped and rotationally symmetrical with a convex curvature with a radius of curvature between 0.2 rf and 1 rf from a location 1.4 rf upstream of the blade plane to a location 0.2 rf downstream thereof. The blade, whose tip radius is rf has a twist at least from a range of ±0.25 rf around a mean radius between hub and tip to the tip such that the airflow velocity through the meridian increases outwardly from the hub of the fan toward the periphery of ...


A propulsion apparatus for generating vertical lift in an aircraft, comprising: a fan shroud defining a substantially vertical airflow passage having an axis, an upper inlet end and a lower outlet end, said passage being rotationally symmetrical about said axis but differing from a right-circular cylinder over its entire length; a fan rotatable in said passage about said axis and having a plurality of generally radial blades where the radial axis of these blades is lying in a plane perpendicular to said axis between said inlet and outlet ends and where t...
