Abstract
A single or multi-bladed rotor for use with a fluid flow generator or reactor, the rotor comprising a central hub which is adapted to be mounted to a rotatable shaft, the rotor further comprises at least one radial blade mounted at one end to the hub, wherein the at least one blade has a fluid reactive face which has the configuration of a logarithmic curve substantially conforming to the golden section, i.e. the order of growth of the radius of the curve which is measured at equiangular radii is constant and conforms to the ratio of 5:8.

A bladed rotor for use with a fluid flow generator or reactor, said rotor comprising a central portion which is adapted to be mounted to a rotatable shaft, the rotor further comprising at least one radial blade mounted at one end to the central portion, each blade having a leading edge and a trailing edge between its one end and its radially outer most extremity, said at least one blade having a fluid reactive face which has the configuration of at least one logarithmic curve substantially conforming to the Golden Section, the at least one blade having a remote face which is remote from the reactive face, said remote face also having the configuration of at least one logarithmic curve substantially conforming to the Golden Section, said trailing and/or leading edge of the rotor having a curvature corresponding to at least one logarithmic curve substantially conforming to the Golden Section.
A bladed rotor as claimed in clam 1 wherein the rotor comprises an aircraft propeller.
