Abstract:
A boundary layer propulsor comprises a rotor and a plurality of first aerofoil blades. The rotor has an axis of rotation. The plurality of first aerofoil blades extends radially from the rotor and is arranged in a circumferential array around the axis of rotation. Each of the first aerofoil blades has, in a radially outward sequence, a radially proximal portion, a middle portion, and a radially distal portion. The radially proximal portion has a first cambered cross-section, the middle portion has a second uncambered cross-section, and the radially distal portion has a third cambered cross-section. The first cambered cross-section is cambered in an opposite sense to the third cambered cross-section.

Claim (Index 10):
A boundary layer propulsion system comprising:\n a machine body having an upstream end and an opposite downstream end; and a boundary layer propulsor comprising:\n a rotor having an axis of rotation; and \n a plurality of first aerofoil blades extending radially from the rotor and arranged in a circumferential array around the axis of rotation, each first aerofoil blade has, in a radially outward sequence, a radially proximal portion, a middle portion, and a radially distal portion, \n wherein the radially proximal portion having a first cambered and the radially distal portion having a third cambered cross-section, the first cambered cross-section being cambered in an opposite sense to the third cambered cross-section, \n wherein the boundary layer propulsor is positioned at the downstream end of the machine body such that a fluid flow passing over the machine body, from the upstream end to the downstream end, flows over the plurality of first aerofoil blades, the fluid flow passing over the radially distal portions of the first aerofoil blades causes a rotation of the boundary layer propulsor relative to the machine body, and thereby causes the radially proximal portions to entrain a boundary layer flow passing over the surface of the machine body to thereby accelerate the boundary layer flow.
