Abstract
Disclosed is an airborne craft comprising an aerodynamic lifting device having a radial drum fan with an operating region intermediate the power loading (“y”) asymptotic region and the disc loading (“x”) asymptotic region of a power loading—disc loading characteristic for the lifting device. The radial drum or vertical axis fan comprises a fan with a rotor, the rotor having a rotational axis and comprising a plurality of rotor blades disposed in an annular ring about the rotational axis and a driving means for the rotor such that, on operation of the driving means, lift is generated.

An aerodynamic lifting device having an operating region intermediate the power loading (“y”) asymptotic region and the disc loading (“x”) asymptotic region of a power loading—disc loading characteristic for the lifting device.
An airborne craft comprising an aerodynamic lifting device having a radial drum fan with an operating region intermediate the power loading (“y”) asymptotic region and the disc loading (“x”) asymptotic region of a power loading—disc loading characteristic for the lifting device.
An aerodynamic lifting device comprising a fan with a rotor, the rotor having a rotational axis and comprising a plurality of rotor blades disposed in an annular ring about the rotational axis and a driving means for the rotor such that, on operation of the driving means, lift is generated.
An airborne lifting device comprising:
- a vertical axis fan with a plurality of blades whose axes are also vertical or near vertical disposed at a distance from said axis, having a chord and radial depth which is small relative to said distance and generating primarily radial airflow;
- a stator assembly that comprises an inner load carrying hub and lifting surfaces, stator blades that are radially inward of and parallel to said fan blades;
- an upper stator blade retainer that may incorporate lifting surfaces;
- and
- an outer shroud that incorporates upper and lower aerodynamic lifting surfaces.
